An experiment was conducted to evaluate the effect of planting pattern, plant density and integration of zeoponix and chemical N fertilizer (urea) on sunflower yield and yield components. The experimental design was analyzed as factorial based on randomized complete block with three replications. Treatments consisted of 3 factors which are different crop densities, including 2 levels. The population of plants was including 5 plants m–2 (d1) and 8 plants m–2 (d2). The second factor was planting patterns which were included twin rectangular rows (A1) and twin zigzag rows (A2). Different fertilizing treatments were selected as third factor consisted of the sole application of zeoponix (f1) and chemical fertilizer urea (f3), and integration of 50%zeoponix +50% chemical fertilizer urea (f2), that were at 3 levels. Results showed that there were significant differences in interaction of planting pattern, plant density and fertilizing system on plant height, stalk diameter, biologic yield, seed yield, number of seeds per head, 1000 seed weight, seed oil content and oil yield, protein content and protein yield and harvest index. LSD test for means of these traits showed that zigzag arrangement × plant population of 8 plants m–2 × 100% zeoponix (a2d2f1) treatment had the best performance and could be recommended to farmers for sunflower cultivation.

— An experiment was conducted in a greenhouse at the Luyengo campus of the University of Swaziland to determine the effect of organic mulch on the growth and yield of spinach. The experiment was conducted between the months of January and February, 2017. The experiment was a completely randomized design (CRD), with treated sewage mulch (TSM) and organic compost mulch (OCM) as treatments. The no mulch (NML) was used as a control. Spinach seedlings were planted at a spacing of 15 cm within rows and 30 cm between rows. Weeding and pest control measures were done uniformly across the treatments, when and as required. The data collected included the percentage moisture retained by the different treatments on the soil, growth parameters (leaf width, leaf length, leaf number, leaf area, plant height) and yield at harvest. The results displayed a significant difference (P<0.05)><0.05). The yield also varied across the treatments as TSM had a dry mass of 43.0 g, followed by OCM at 23.4 g and the no mulch treatment recorded a dry mass of 20.9 g. The results showed that mulching improved the performance of the spinach plants in terms of plant growth, moisture retention and yield.
When plants of the same kind are grown and cultivated at the one place on a large scale, it is called a crop.

An experiment was conducted at the Crops Research Station of the Kenya Agricultural and Livestock Research Organization Alupe, Busia County. The experiment was performed to find out the most suitable mulching material and an ideal spacing for green pepper cultivation under Busia County Conditions. The experiment was laid out in a Factorial Randomized Block Design with three replications. The treatments comprised of four mulching materials viz. black plastic mulch, transparent plastic mulch, straw mulch and bare soil which was the control with three row spacings viz. 30 x 50 cm, 40 x 40 cm and 50 x 40 cm. Data collected was subjected to SAS statistical software for analysis and means separated using LSD at P≤0.05. Significant responses on plant height and number of branches per plant were observed for both seasons due to spacing and mulching treatments. The highest branches (6.97) per plant were recorded in the 40 by 40 cm spacing under the transparent mulch with the lowest (2.83) shown under the same spacing in the straw mulch of California Wonder variety. The widest spacing elicited the highest number of fruits per plant (7.37) in the black plastic mulch while only a mean of 1 fruit per plant was recorded in the mulch control during the short rain season. The highest fruit mean yield per plant of 1556 g and 1533 g was recorded in the widest spacing (50 by 40cm) during the long and short rain seasons respectively. Therefore this study recommends the use of plastic mulches at wider spacing.

Growth of Bush Pepper Seedlings of Different Sources of Cuttings Grown on Var...AI Publications
Pepper grows creepingly following the growth of its climbing plants, making it difficult to maintain and harvest. Therefore, bush pepper cultivation was developed by replacing climbing trees with 1.5 m high concrete. However, seedlings that can grow into bush pepper are cuttings from fruit branches and primary branches, which are difficult to grow because the nodes of these branches do not have root primordia. This study aimed to obtain cuttings that can grow into bush pepper on the most superior growing media. The experiment was arranged using a completely randomized design (CRD) with two treatment factors, namely formulas of growth media (M1= soil + organic fertilizer + husk; M2= soil + organic fertilizer + compost; M3= soil + organic fertilizer + husk ash; and M4= soil + organic fertilizer + moss) and sources of cuttings (S1= climbing stem; S2= axillary branch; S3= fruit branch; and S4= primary branch with one main stem node). Based on the growth percentage of fruit branches and primary branches in the seedlings, cuttings from climbing stem and axillary branches were not able to grow into bush pepper, because fruit and primary branches only grew less than 5% in all media formulas. Cuttings from fruit branches and primary branches affect the formation of bush pepper with an average percentage of growth of fruit branches and primary branches of more than 95% on M2 and M3 media. Growth of buds, leaves and roots of cuttings from climbing stem and axillary branch was significantly better than cuttings from fruit branches and primary branches.
Zeolite and Urea Fertilizer in the Growth and Yield of MaizeQUESTJOURNAL
ABSTRACT: Karo district is the center of the corn crop in northern Sumatera. Farmers use inorganic fertilizer on top recommendation, is not good for the soil, plants, and costs. Zeolite, alumino silicate compound hydrated the main elements: alkali cations, alkaline soil and have the property of absorbing, separator, catalisator, fixing soil and the efficiently of Urea. The purpose of this study were to understand zeolite, urea and interaction on the growth and yield of corn. The researchers use RAK factorial method, I zeolit: Z0 0 g/plot, Z1 105 g/plot, Z2 210 g/plot, Z3 315 g/plot. Z4 420 g/plot. II urea: U0 0 g/plant, U1 2,1 g/plant, U2 4,2 g/plant, U3 6,3 g/plant, U4 8,4 g/plant. The result shows that real zeolite affect plant height, leaf area, production and weight of 100 seeds, not unlike the stem diameter, number of leaves, number of cob. Urea real effect on plan height, leaf area, and production but did not differ on stem diameter, number of leaves, dry weight of 100 seeds and cobs line. So zeolite are 315 (Z3) and Urea 6.3 g/crop (U3), interaction (Z3U3).
Influenced of Yield and Yield Contributing Characters of Tuberose by the Appl...Agriculture Journal IJOEAR
Abstract— The experiment was conducted at the Horticultural farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to investigate the influenced of yield and yield contributing characters of tuberose by the application of bulb and fertilizers. The experiment consisted of three bulb size viz., B1- small (1.0-1.5 cm ); B2- medium (1.6-2.5 cm) and B3- large (2.6-3.0 cm ) in diameter and different sources of fertilizers viz.,F0= control (no fertilizers ), F1- chemical fertilizers 330, 150 and 200 kg ha-1 of urea, TSP and MoP, respectively; F2- vermicompost 5 t ha-1; F3- poultry litter 10 t ha-1 and F4- cowdung 20 t ha-1. The experiment was laid out in a two factor Randomized Complete Block Design with three replications. The growth parameters as well as yield characters were greatly influenced by the application of poultry manure. In case of bulb size, the highest flower (12.45 t ha-1) and bulb (23.93 t ha-1) yield was recorded from B3 and the lowest flower (8.83 t ha-1) and bulb (12.94 t ha-1) yield was recorded from B1. In case of fertilizers, the highest flower (12.09 t ha-1) and bulb (21.36 t ha-1) yield was recorded from F3 and the lowest flower (7.95 t ha-1) and bulb (14.44 t ha-1) from F0. The maximum flower (14.19 t ha-1) and bulb (27.19 t ha-1) was found from the treatment combination of B3F3 and the minimum flower (6.16 t ha-1) and bulb (10.15 t ha-1) yield from B1F0. So, it may be concluded that large bulb size and 10 t ha-1 poultry litter is best for growth, bulb and flower production of tuberose.

The effect of dosage of mycorrhizal Glomus mosseae and some varieties on grow...Innspub Net
This study aims to determine the effect of Glomus mosseae mycorrhizae dose and varieties on growth and yield of chili (Capsicum annum. L) on Entisol soil. This research was conducted at the UNSYIAH Experimental Garden, Banda Aceh. The design used in this study is factorial randomized block design (RBD). The first factor in this study is the dose of mycorrhizal Glomus mosseae (D) consisting of 4 levels, namely: D0= without mycorrhiza, D1= mycorrhiza Glomus mosseae 5g plant-1, D2= mycorrhiza Glomus mosseae 10g plant-1, and D3= mycorrhiza Glomus mosseae 15g plant-1. The second factor is chili variety (V) consisting of 3 levels, namely: PM 999 varieties, Lado F1 varieties, varieties CTH-01. The variables observed were growth parameters, chili yield, total N-content and P-available on Entisol soil and the percentage of mycorrhizal infected roots. The results showed that mycorrhizal doses were able to increase the value of N-total and P-available on the soil and can improve plant growth and yield, the use of mycorrhizal doses of 15 g tan-1 generally results in better growth and yield of chilli compared to other doses, while based on the results of research CTH-01 varieties affect the growth and yield of chili plants. There is an interaction between mycorrhizal doses with chilli varieties on growth parameters and chili yield.
Field experiment involving five improved onion (Allium cepa L.) varieties and carried out at Kulumsa Agricultural Research Center during the 2018 to 2019 cropping seasons under irrigated condition to identify the best performing variety for seed production to the target areas of Arsi Zone. The onion varieties included in the field experiment were (Nafis, Robaf, Nasic Red, Bombe Red, and Adama Red). The experimental design was a randomized complete block design (RCBD) with three replications. Phenological and growth parameters, seed yield, and yield components were studied. The result showed that Variety had a significant effect on most phonological and growth attributes as well as on yield attributes. The number of days to flowering and vigorously were significantly affected by variety; while plant height, days to boolting and branch number was not significantly influenced by variety. Flower stalks height and diameter, number of umbel per plant, and umbel diameter also significantly affected by variety. Seed yield per umbel and mean seed yield per hectare also showed a significance difference among varieties. The highest seed yield per hectare (1415.89 kg/ha) was recorded from Adama Red and followed by Nafis variety, whereas Nasic rerd, Bombe red and Robaf show no significance difference among each other, Therefore, it can be concluded that use of the improved onion varieties such as Adama red and Nafis is advisable and could be appropriate for onion seed production in the test area even though further testing is required to put the recommendation on a strong basis.
Bolting in onion bulb crops as influenced by cultivars and transplanting date...Innspub Net
Bolting reduces the quality and commercial yield of bulb onion, however, seed production is directly dependent on flower induction and bolting. Field experiments were conducted during two cropping seasons 2013-14 and 2014-15 at the Agricultural Research Institute, Swat, Pakistan to study the effects of three onion cultivars with five transplanting dates on bolting and marketable yield of onion. Seedlings of three onion cultivars were transplanted on five different dates with 15 days interval in a randomized complete block design. Onion cultivars varied in their susceptibility to bolting. Cultivar Swat-1 took significantly maximum days to bolting initiation and recorded a minimum bolting percentage compared to ‘Saryab Red’ and ‘Chiltan-89’. Early transplanting took 108.06 days to bolting initiation. The Bolting percentage was maximum at early transplanting and reduced with delay in transplanting from 25th November to 25th December. Bolting has not been recorded at late, (10th and 25th January) transplanting irrespective of the cultivar. Compare to ‘Saryab Red’ and ‘Chiltan-89’, ‘Swat-1’ has maximum plant height, leaves per plant, bulb diameter, bulb weight, total and marketable yield ton ha-1. Bulb diameter, bulb weight, days to maturity, and total yield ton ha-1 was maximum at early transplanting and decreased with delay in transplanting. Marketable yield was maximum at mid transplanting date (25th December); attributed to less bolting and percent cull compared to early transplanting. Unmarketable yield at early transplanting was largely due to bolting while at late transplanting it was due to small ungraded bulbs.
This study aimed to determine the population and percentage of larval attacks S.
exigua on leaf onion plants. This research was conducted for two months. Sampling
was done by directly observing each plant at a predetermined location three times at
intervals of two weeks. Based on the results of the study it can be concluded that the
average population of S. exigua larvae was highest in leaf onion plants in Yaba Maru
0.144 heads/clump and the lowest was Waninggap Miraf 0.039 tail/clump. While the
average attack rate of S. exigua larvae was highest in leaf onion plants at location 4
7.639% and lowest at Waninggap Miraf 3.14%.
— A pot experiment was conducted to study the effects of potting media on sprouting and seedling growth of grape cuttings. Three grape varieties viz. Red globe, Thomson seedless and Crimson seedless were planted in four different growth media: CS-Canal silt, CSFYM-Canal silt (75%) + FYM (25%), CSB-Canal silt (25%) + Bagasse (75%) and CSBCP-Canal silt (25%) + Bagasse (50%) + Coco peat (25%). The experiment was conducted in Completely Randomized Design (CRD) along with three replications. The results revealed that almost all observed parameters were significantly influenced by the potting media. However, grape varieties and their interaction with the potting media exhibited non-significant effect for sprouting percentage and most of the seedling related attributes of growth. Minimum days to sprouting (6.78),highest sprouting percentage (84.44), maximum rooting percentage (84.44) and maximum chlorophyll content of leaves (56.23) were observed from the cuttings planted in CSBCP. However, maximum number of sprouts (5.55), number of leaves (13.77), fresh weight of leaves (2.27g), fresh weight of the roots (2.16 g), were observed from CSB. No grape seedling mortality was also observed CSB and CSBCP growth media. On the basis of varietal comparison, Thompson seedless exhibited the best results for number of leaves per cutting (11.50), fresh weight of the roots (1.64 g) and number of roots per cutting (29.17 g) as compared to rest of the grape varieties. The research establishes the potential for locals to use available materials in potting media preparation for healthier and stronger grape seedlings for subsequent improved grape plantation.
Nitrogen (N) is one of the most important nutrients for plant growth and productivity. Hence its judicious use in crop cultivation is essential for achieving desirable productivity of crops. A pot experiment was designed in the experimental site of the Horticulture Garden, Sindh Agriculture University, Tandojam during 2014-15, using Randomize complete design (CRD), where five cultivars of chilli (Kunri 1, Nagina, Ghotki, Tota puri and Longi) were evaluated to four nitrogen levels, including a control, (0, 50, 150 and 250 kg ha-1). The results exhibited that all growth and yield characters of chilli were significantly (P<0.05) influenced by N levels and cultivars. However, interaction between N levels × cultivars was only significant (P<0.05) for plant height (cm) and branches plant-1. The plants treated with higher N level of 250 Kg ha-1 produced maximum plant height (71.27 cm), number of branches (9.42), days to flower initiation (74.62), fruit length (3.12 cm), fruits plant-1 (142.00), weight of single fruit (3.44 g) and fresh weight of fruit plant-1 (486.36). The plants fertilized with 150 kg ha-1 ranked second and showed plant height (70.56 cm), number of branches (9.06), days to flower initiation (exposed) 74.33, fruit length (3.02), fruits plant-1 (139.20), weight of single fruit (3.34), and fresh weight of fruit plant-1 (468.51). There was significant reduction in all the growth and yield attributed parameters at control, where N was not applied to plants. Among cultivars, Ghotki exhibited a better performance. Moreover, interaction of N levels and cultivars (250 Kg ha-1 x Ghotki) also displayed higher values for most of the traits. The findings of the current study demonstrated that although higher N level 250 kg ha-1 showed greater values for all traits, but these results were statistically similar to results obtained from 150 kg ha-1, Hence, it is concluded that N 150 Kg ha-1 is an economic dose for better growth and fruit yield of Chillies.
Effect of Transplanting Age on the Growth and Yield of Green Pepper (Capsicum...BRNSS Publication Hub
A field experiment was conducted at the research farm of the Department of Crop Production and
Landscape Mangement of the Faculty of Agriculture, Ebonyi State University, Abakiliki, in Southeasthern
Agro-ecological zone of Nigeria for a period of 8 weeks to study the effect of transplanting age on
growth and yield of green pepper, laid out in a randomized complete block design in four replicates.
The agronomical characteristics that were measured were as follows: Plant height, number of leaves per
plants, days to 50% flowering, number of fruit per plot, and weight of fruit per plot (kg/plot). The result
of the field trial showed that transplanting age had a significant effect only on plant height at 8 weeks
of age of transplanting. The other vegetative parameters such as number of branches, number of leaves,
and 50% flowering and field component such as number and weight of fruits were not affected by the
transplanting age. Therefore, the best age to transplant green pepper is from 1 to 7 weeks, for optimum
performance.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

PENDAHULUAN
Bawang daun (Allium fistulosum L.) merupakan salah satu jenis komoditas sayuran potensial dan
layak dikembangkan secara intensif dalam skala agribisnis. Di Indonesia bawang daun merupakan salah satu
jenis tanaman sayuran yang digunakan sebagai bahan penyedap rasa (bumbu) dan bahan campuran sayuran
lain pada beberapa jenis makanan populer di Indonesia, seperti soto, sup, campuran bumbu mi instan, dan
penyedap jenis makanan lainnya. Peningkatan permintaan bawang daun tidak hanya dikalangan rumah
tangga, melainkan produsen makanan instan yang menggunakan bawang daun sebagai bumbu bahan
penyedap rasa.
Luas panen bawang daun rata-rata dari seluruh provinsi di Indonesia pada tahun 2009 sampai 2014
yaitu 58.362 Ha dengan produksi sebesar 584.624 ton, sehingga diperoleh rata-rata produksi bawang daun
10,02 ton/ha (Direktorat Jenderal Hortikultura, 2015). Produksi bawang daun di daerah Jawa Tengah pada
tahun 2016 adalah 1.167.000 kuintal. Produksi bawang daun Jawa Tengah secara umum mengalami tren
yang meningkat, akan tetapi untuk periode tahun 2014 sampai 2016 tren produksi bawang daun menurun.
Produksi tahun 2016 lebih rendah bila dibandingkan dengan tahun 2015 karena turunnya luas panen (Dinas
Pertanian dan Perkebunan, 2017). Permintaan bawang daun di pasar saat ini semakin meningkat seiring
dengan meningkatnya laju pertumbuhan penduduk. Oleh sebab itu, untuk menjaga keseimbangan antara

produksi dan permintaan harus diimbangi dengan teknik budidaya yang tepat. Salah satu teknik budidaya
yang dapat diperhatikan untuk meningkatkan produksi bawang daun yaitu dengan pengaturan jarak tanam
dan pemotongan bibit anakan.
Kerapatan tanaman atau jarak tanam dapat berpengaruh terhadap hasil tanaman bawang daun.
Kerapatan tanaman mempunyai hubungan yang tidak dapat dipisahkan dengan hasil yang akan diperoleh.
Kerapatan tanaman penting diketahui untuk menentukan sasaran agronomi, yaitu produksi optimum.
Semakin meningkatnya populasi akan terjadi persaingan dalam hal pengambilan air, unsur hara dan cahaya
matahari antar tanaman sehingga terjadi penurunan produksi. Selain unsur tanaman sendiri yang berpengaruh
terhadap kerapatan tanaman, faktor tingkat kesuburan tanah, kelembaban tanah juga akan menimbulkan
persaingan apabila kerapatan tanaman makin besar (Jumin, 1994 dalam Zulaiha, 2006).
Selain penambahan jarak tanam, hal yang perlu diperhatikan untuk memperoleh hasil yang optimal
dalam membudidayakan tanaman bawang daun, adalah bibit yang akan ditanam. Bawang daun dapat
diperbanyak dengan biji atau dapat pula berupa stek tunas atau anakan. Sebelum ditanam, umumnya bibit
anakan dipotong sebagian daunnya. Hal ini bertujuan untuk mengurangi penguapan dari bibit sekaligus
untuk merangsang pertumbuhan tunas dan akar-akar baru, memperbanyak jumlah anakan dan daun sehingga
produksinya akan tinggi (Cahyono, 2011).
Penelitian bertujuan untuk menentukan jarak tanam yang paling efektif bagi pertumbuhan dan hasil
tanaman bawang daun, panjang pemotongan bibit anakan yang paling efektif bagi pertumbuhan dan hasil
tanaman bawang daun, dan mendapatkan kombinasi jarak tanam dan panjang pemotongan bibit anakan yang
paling efektif bagi pertumbuhan dan hasil tanaman bawang daun.
METODE PENELITIAN
Penelitian dilaksanakan pada bulan April - Juni 2018 di Dusun Gewok, Desa Karanggintung,
Kecamatan Sumbang, Kabupaten Banyumas dan Laboratorium Agroteknologi, Fakultas Pertanian,
Universitas Jenderal Soedirman.
Bahan yang digunakan pada penelitian ini antara lain bibit bawang daun, pupuk kandang kambing,
pupuk urea, pupuk SP 36, pupuk KCl, pupuk organik cair, bibit tanaman border (kemangi dan bunga kertas),
sebidang lahan, air, dan pestisida nabati. Alat yang digunakan meliputi cangkul, pancong, tugal, gembor,
meteran, jangka sorong plastik merk sellery, tali rafia, gunting, termohigrometer, lux meter, gelas ukur
ukuran 10 ml, hand sprayer, papan nama, logbook, oven, timbangan analitik, alat tulis, dan kamera.
Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan dua faktor. Faktor
pertama yaitu jarak tanam terdiri dari 3 taraf, yaitu (15 x 20) cm, (20 x 20) cm, dan (25 x 20) cm. Faktor
kedua yaitu pemotongan bibit anakan terdiri dari 3 taraf, yaitu tanpa pemotongan, dipotong 1/2 bagian dari
ujung tanaman, dan dipotong 2/3 bagian dari ujung tanaman.
Variabel yang diamati meliputi tinggi tanaman, jumlah daun per rumpun, jumlah anakan per rumpun,
luas daun, panjang akar, volume akar, bobot segar tanaman, bobot kering tanaman, dan bobot petak efektif.
Data yang diperoleh dianalisis menggunakan uji F, apabila terdapat keragaman dilanjutkan dengan uji
DMRT (Duncan’s Multiple Range Test) pada taraf 5% dan 1%.
Tinggi tanaman merupakan rata-rata tinggi tanaman sampel dari setiap petak percobaan. Pengukuran
dilakukan dari pangkal batang sampai pada ujung daun tertinggi. Pengamatan dilakukan 43 hari setelah
tanam (hst). Jumlah daun per rumpun merupakan rata-rata jumlah daun tiap rumpun tanaman sampel yang
dihitung dari daun yang sudah terpisah dari ujung batang sampai dengan daun yang masih berwarna hijau.
Pengamatan dilakukan 43 hst. Jumlah anakan per rumpun adalah rata-rata banyaknya anakan dari
tanaman sampel pada tiap petak percobaan yang sudah terpisah dari tanaman induk. Pengamatan dilakukan
43 hst. Pengukuran luas daun dilakukan dengan mengalikan jumlah daun dengan luas daun tiap individu
daun. Luas individu daun diukur dengan rumus luas kerucut karena bentuk bawang daun berbentuk kerucut.
Pengamatan dilakukan pada saat panen (60 hst).
Luas daun dihitung dengan rumus sebagai berikut: Luas kerucut = 𝜋. 𝑟2 + 𝜋. 𝑆. 𝑟

r = jari – jari lingkaran alas kerucut
S = panjang dinding kerucut/ sisi miring kerucut
Panjang akar adalah rata-rata panjang akar dari tiap tanaman sampel pada tiap petak percobaan.
Pengukuran panjang akar dilakukan pada akar yang paling panjang yang telah dibersihkan. Pengamatan
dilakukan pada saat panen (60 hst). Volume akar dapat diperoleh dengan cara menghitung berapa banyak
penambahan air saat akar dimasukkan kedalam gelas ukur berisi air.
Perhitungan dilakukan pada saat panen (60 hst). Bobot segar tanaman diperoleh dengan cara
menimbang masing-masing tanaman sampel dari seluruh bagian tanaman termasuk akar, setelah bawang
daun dicabut dan dibersihkan dengan air kemudian ditiriskan. Pengamatan dilakukan pada saat panen (60
hst). Bobot kering tanaman diperoleh dengan cara menimbang masing-masing tanaman sampel dari seluruh
bagian tanaman termasuk akar yang dikeringkan dengan oven pada suhu 70° C sampai didapatkan bobot
tanaman kering yang konstan. Bobot tanaman per petak dihitung dengan cara mengambil tanaman pada
petak selain tanaman border. Sampel tanaman pada petak efektif ditimbang secara keseluruhan menggunakan
timbangan. Penimbangan dilakukan saat tanaman panen (60 hst).
Pengolahan tanah dilakukan berupa pembersihan rumput dan penggemburan dengan kedalaman 20-30
cm, setelah itu diratakan dan dibuat bedengan (1 x 1 m) dengan tinggi bedeng 30 cm, jarak antar bedeng 40
cm dan jarak antar ulangan 75 cm. Pupuk dasar yang digunakan yaitu pupuk kandang kambing. Pupuk dasar
diberikan 3 hari sebelum tanam yaitu setelah selesai melakukan pengolahan tanah, dengan dosis 15 ton/ha.
Pupuk kandang diberikan dengan cara mencampurnya dengan tanah pada setiap bedeng sedalam 15-20 cm.
Bibit bawang daun yang telah disortir menurut ukurannya ditanam di petak percobaan yang sebelumnya
telah dibuat lubang tanam dengan menggunakan tugal sedalam 5 cm dengan jarak tanam sesuai perlakuan
yaitu (15 x 20) cm (35 tanaman/petak), (20 x 20) cm (25 tanaman/petak) dan (25 x 20) cm (20
tanaman/petak), setiap lubang ditanam 1 bibit bawang daun, penanaman dilakukan sore hari. Penyiraman
dilakukan pada pagi dan sore hari pada minggu pertama setelah tanam. Penyiraman berikutnya secara
berangsur-angsur dikurangi, yaitu 1-2 hari sekali yang dilakukan pada sore hari pada saattidak ada hujan.
Tanaman bawang daun dipanen pada umur 60 hari setelah tanam yangditandai dengan beberapa helai daun
bawah telah menguning atau mengering.Pemanenan dilakukan dengan mencabut seluruh bagian tanaman
termasuk akar.
HASIL DAN PEMBAHASAN
Hasil analisis uji F pengaruh perlakuan jarak tanam dan pemotongan bibit anakan disajikan pada tabel
1. Berdasarkan hasil analisis ragam diketahui bahwa jarak tanam menunjukkan pengaruh sangat nyata pada
variabel bobot petak efektif dan tidak menunjukkan pengaruh nyata pada variabel lain (Tabel 1). Penggunaan
jarak tanam 15 cm x 20 cm (J1) pada Gambar 1 menghasilkan bobot petak efektif tertinggi yaitu sebesar
1.279 g dibandingkan dengan dua perlakuan lainnya. Hal ini menunjukkan bahwa pada jarak tanam yang
sempit bawang daun memiliki populasi lebih banyak dibandingkan dengan jarak tanam yang lebih lebar
sehingga mempengaruhi bobot dalam tiap petaknya. Bentuk daun dari tanaman bawang daun yang berbentuk
kerucut juga mempermudah untuk memperoleh intensitas matahari yang optimal. Intensitas cahaya matahari
yang optimal akan membantu daun melakukan fotosintesis untuk menghasilkan fotosintat yang kemudian
disebarkan ke seluruh bagian tanaman sebagai energi untuk perkembangan dan pembelahan sel.

1. Pengaruh Jarak Tanam Terhadap Pertumbuhan dan Hasil Bawang Daun
Gambar 1. Pengaruh perlakuan jarak tanam terhadap bobot petak efektif tanaman bawang
daun.
Semakin banyak energi yang dihasilkan maka akan semakin baik pertumbuhan dan perkembangan
tanaman. Menurut Kuyik et al. (2012), fotosintesis adalah proses dasar pada tanaman untuk menghasilkan
makanan. Makanan yang dihasilkan akan menentukan ketersediaan energi untuk pertumbuhan dan
perkembangan tanaman.
Hasil bobot petak efektif pada perlakuan jarak tanam 15 cm x 20 cm (J1) sesuai dengan penelitian Zamil
et al. (2010) pada tanaman kentang dengan umbi tertinggi diperoleh pada jarak tanam yang relatif lebih rapat dan
hasil terendah pada jarak tanam lebar, didukung oleh pernyataan Sumpena dan Meilani (2005) yang melakukan
penelitian tanaman wortel, bahwa bobot umbi per plot selain dipengaruhi oleh bobot umbi per tanaman juga
dipengaruhi oleh jumlah populasinya, dimana pada jarak tanam yang rapat populasi tanaman lebih banyak.
Perlakuan jarak tanam menunjukkan pengaruh tidak nyata terhadap variabel pertumbuhan dan variabel
hasil lainnya diduga karena dalam petak percobaan belum terjadi persaingan yang sangat ketat antar tanaman
sehingga hara, air, serta cahaya matahari masih dapat diserap oleh tanaman dalam jumlah yang sama. Menurut
Lakitan (2008) jumlah unsur hara yang dibutuhkan suatu tanaman sangat berkaitan dengan kebutuhan tanaman
untuk dapat tumbuh dengan lebih baik, jika jumlah unsur hara kurang tersedia maka pertumbuhan akan
terganggu yang juga akan mempengaruhi produksi tanaman.
Hasil analisis tidak menunjukkan perbedaan nyata pada variabel lain, namun pada perlakuan 20 cm x 20
cm (J2) cenderung memberikan respon pertumbuhan dan hasil yang lebih baik yaitu pada variabel luas daun,
bobot segar tanaman, dan bobot kering tanaman dibandingkankan dengan dua taraf lainnya. Semakin luas
permukaan daun maka penyerapan cahaya matahari akan semakin optimal sehingga fotosisntesis berjalan dengan
baik menghasilkan fotosintat yang kemudian di translokasikan keseluruh bagian tanaman sebagai energi dalam
metabolisme. Menurut Ratri et al. (2015) luas daun berpengaruh pada proses fotosintesis untuk menghasilkan
asimilat yang digunakan sebagai sumber energi pertumbuhan dalam membentuk organ-organ vegetatif tanaman
yang berakibat pada peningkatan biomassa tanaman. Luas daun merupakan parameter pertumbuhan tanaman
yang berpengaruh dengan parameter pertumbuhan yang lain, termasuk bobot kering tanaman.

2. Pengaruh Pemotongan Bibit Anakan terhadap Pertumbuhan dan Hasil Bawang Daun
Gambar 2. Pengaruh perlakuan pemotongan anakan terhadap tinggi tanaman bawang daun.
Berdasarkan analisis ragam diketahui bahwa pemotongan bibit anakan menunjukkan pengaruh sangat
nyata pada variabel tinggi tanaman dan tidak menunjukkan pengaruh nyata para variabel lain (tabel 1).
Pemotongan bibit anakan sebanyak ½ bagian pada gambar 2 menunjukkan tinggi tanaman yang lebih tinggi
dibandingkan dengan pemotongan 2/3 bagian (Gambar 2). Hal ini diduga pada pemotongan ½ bagian, daun yang
tersisa lebih banyak serta tunas baru tidak terpotong dibandingkan perlakuan pemotongan P3 dimana daun yang
terpotong lebih banyak dapat mengakibatkan tunas baru ikut terpotong. Menurut Jumini (2010), pada
pemotongan ¼ bagian umbi bawang merah mampu merangsang pembentukan hormon tumbuh tanpa
mengganggu mata tunas. Sebaliknya, pemotongan umbi bibit 1/3 bagian diduga mengganggu mata tunas
sehingga pertumbuhannya terganggu.
Berdasarkan hasil analisis rata-rata jumlah daun dan jumlah anakan menunjukkan pengaruh yang tidak
nyata. Hal ini menunjukkan perlakuan pemotongan tidak memberikan pengaruh yang signifikan, sebab ada
faktor lain yang juga dapat mempengaruhi keduanya seperti faktor suhu dan intensitas matahari. Hasil analisis
juga menunjukkan pengaruh tidak nyata terhadap variabel luas daun, panjang akar, volume akar, bobot segar
tanaman, bobot kering tanaman, dan bobot petak efektif. Hal ini diduga karena adanya keterkaitan antara jumlah
anakan dengan variabel lainnya. Menurut Fatmawaty (2015), jumlah daun tanaman merupakan komponen yang
dapat menunjukkan pertumbuhan tanaman. Pembentukan daun sendiri sebetulnya dipengaruhi oleh sifat genetik
tanaman, namun lingkungan yang baik dapat mempercepat pembentukkan tersebut.
Tanaman yang mendapat perlakuan pemotongan bibit anakan ½ bagian dari ujung tanaman cenderung
memberikan respon pertumbuhan dan hasil yang lebih baik dibandingkan tanpa pemotongan dan pemotongan
2/3. Menurut Qibtiah (2016), bibit anakan bawang daun yang tidak dipotong mengalami dominansi apikal.
Kuncup apikal memberikan pengaruh yang menghambat (dominansi apikal) terhadap kuncup samping dengan
mencegah atau memperlambat perkembangannya. Bagian ujung batang atau daun mempengaruhi pertumbuha

dan perkembangan bagian tumbuhan lainnya. Bahwa pemotongan bagian ujung batang atau tanaman berarti
mengurangi jumlah auksin pada bagian tersebut, sehingga membuka peluang bagi tunas-tunas samping untuk
tumbuh, pemotongan bibit anakan dapat mempercepat pertumbuhan tunas, memperbanyakan jumlah anakan
dan daun sehingga produksinya akan tinggi.
3. Pengaruh Interaksi Jarak Tanam dengan Pemotongan Bibit Anakan terhadap Pertumbuhan
dan Hasil Bawang Daun
Hasil analisis ragam pada Tabel 1 menunjukkan bahwa interaksi antara jarak tanam dengan
pemotongan anakan memberikan pengaruh tidak nyata terhadap tinggi tanaman, jumlah daun, jumlah
anakan, luas daun, panjang akar, volume akar, bobot segar tanaman, bobot kering tanaman, serta bobot petak
efektif. Keadaan ini menunjukkan bahwa antara faktor jarak tanam dan pemotongan bibit anakan tidak
mempengaruhi pertumbuhan dan hasil bawang daun secara bersama-sama. Steel dan Torrie (1991)
mengatakan bahwa bila pengaruh interaksi berbeda tidak nyata, maka disimpulkan bahwa diantara faktor-
faktor perlakuan tersebut bertindak bebas satu dengan yang lainnya atau pengaruhnya berdiri sendiri. Hal ini
berarti bahwa perbedaan pertumbuhan dan hasil bawang daun akibat perbedaan perlakuan jarak tanam tidak
tergantung pada berbagai ukuran pemotongan anakan ataupun sebaliknya. Tidak adanya pengaruh yang
nyata dari interaksi tersebut disebabkan karena perlakuan jarak tanam pengaruhnya terhadap kompetisi antar
tanaman dalam memperoleh hara, air, dan cahaya matahari, dimana dalam penelitian ini tidak terjadi
kompetisi antar tanaman sehingga pada jarak tanam yang sempit menunjukkan hasil yang lebih tinggi,
sedangkan pemotongan bibit anakan pengaruhnya terhadap tubuh tanaman dengan mengurangi hormon
auksin pada tanaman yang bertujuan untuk merangsang pertumbuhan tunas baru, anakan, serta akar.
KESIMPULAN
Penggunaan jarak tanam (15 x 20) cm merupakan perlakuan yang paling efektif untuk meningkatkan
bobot petak efektif yaitu sebesar 1.729 g dibandingkan dengan jarak tanam (20 x 20) cm sebesar 872,33 g
dan (25 x 20) cm sebesar 613,66 g; Pemotongan bibit anakan ½ bagian dari tinggi tanaman merupakan
perlakuan paling efektif untuk meningkatkan tinggi tanaman yaitu sebesar 56,12 cm dibandingkan dengan
tanpa pemotongan sebesar 54,1 cm dan pemotongan 2/3 bagian sebesar 50,64 cm; dan Tidak terdapat
kombinasi yang paling baik antara jarak tanam dan pemotongan bibit anakan untuk meningkatkan
pertumbuhan dan hasil tanaman bawang daun.
