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.

Growth, Yield and Economic Advantage of Onion (Allium cepa L.) Varieties in R...AI Publications
Haphazard and low soil fertility, low yielding verities and poor agronomic practices are among the major factors constraining onion production in the central rift valley of Ethiopia. Therefore, a field experiment was conducted in East Showa Zone of Adami Tulu Jido Combolcha district in central rift valley areas at ziway from October 2021 to April 2022 to identify appropriate rate of NPSB fertilizer and planting pattern of onion varieties. The experiment was laid out in split plot design of factorial arrangement in three replications. The main effect of NPSB blended fertilizer rates and varieties (red coach and red king) significantly (p<0.01) influenced plant height, leaf length, leaf diameter, leaf number and fresh leaf weight, shoot dry matter per plant, and harvest index. Total dry biomass, bulb diameter, neck diameter, average fresh bulb weight, bulb dry matter, marketable bulb yield, and total bulb yield were significantly (p<0.01) influenced only by the main effect of NPSB blended fertilizer rates. In addition, unmarketable bulb yield was statistically significantly affected (p≥0.05) by the blended fertilizer rates and planting pattern. Moreover, days to 90% maturity of onion was affected by the main factor of NPSB fertilizer rate, variety and planting pattern. The non-fertilized plants in the control treatment were inferior in all parameters except unmarketable bulb yield and harvest index. Significantly higher marketable bulb yield (41 t ha-1) and total bulb yield (41.33 t ha-1) was recorded from 300 kg ha-1 NPSB blended fertilizer rate applied. Double row planting method and hybrid red coach onion variety had also gave higher growth and yields. The study revealed that the highest net benefit of Birr, 878,894 with lest cost of Birr 148,006 by the combinations of 150 kg blended NPSB ha-1 with double row planting method (40cm*20cm*7cm) and red coach variety which can be recommendable for higher marketable bulb yield and economic return of hybrid onion for small scale farmers in the study area. Also, for resource full producers (investors), highest net benefit of Birr 1,205,372 with higher cost (159,628 Birr) by application of 300 kg NPSB ha-1 is recommended as a second option. However, the research should be replicated both in season and areas to more verify the recommendations.

Seed management’s influences on nodulation and yield of improved variety of s...Agriculture Journal IJOEAR
Abstract— A pot study was carried out on an improved soybean variety (TGX 1448-2E) to assess the effects of seed management on its nodulation and yield. The experiment was in factorial combinations with six replicates at the teaching and research farm of University of Abuja. The factors were 2 soils, 2 levels of phosphorus fertilizer (-P and + P), and 2 seed sources (farmer’s and researcher’s managed seeds). P was applied as triple superphosphate at 30 kg P ha-1. Destructive sampling was done at 8 weeks after planting to record growth parameters and nodulation. At maturity, the number and weight of pods, weight of 50 seeds and total seed yield were recorded. The results showed that generally researchers’ managed seeds showed a significantly higher mean values than farmers’ managed seeds. The pod and total seed weight from researchers’ seeds were 106.26 g and 52.43 g per plant respectively against the farmers’ managed seed with pod weight of 80.23 g and total seed weight of 44.35 g per plant. P application influenced significantly the weight of nodules, pods and seeds per plant. This significant lower performance observed in farmers’ managed seeds could have resulted from factors such poor seed handling or mix up during harvesting or storage, poor quality seed selection for planting.

Fruit relative water content, carotenoid total chlorophyll content, flowering, fruition, growth and yield parameters of pepper (Capsicum annuum L.) cultivars: ‘Granada’, ‘Goliath’ and ‘Nobili’ were evaluated under two level of irrigation water: tap water (control) and tap water + 50mm NaCl, organic and inorganic fertilization in order to determine the field performance, for the improvement of smallholder agriculture in Cameroon. Four fertilizer application rates (0, 3, 6 and 12 t.ha-1) of Water Lettuce (WL) and Poultry Manure (PM) and 100kg/ha of NPK were used in a randomized complete block design experiment with four replications. The results overall indicated that the raising of fertilizer application rate of PM an WL increased significatively (p<0.05) carotenoid content, fruit water content, growth and agronomical parameters and decreased the date of flowering and fruition for all varieties studied compared to the control and NPK fertilizer, and what it regardless of the level of salinity. Application of WL or PM at 12 t ha-1 and NPK significantly increased fruit water content, growth and yield parameters in Granada compared to other cultivars. Irrigation of saline water decreased significantly (p<0.05) growth and yield parameters of all varieties. Significant (p<0.05) increased in growth parameters was observed in all cultivars at NPK fertilization. ‘Granada’ showed better growth and yield than ‘Nobili’ and ‘Goliath’ revealing a greater response of this cultivar to fertilization. This study is important contribution to identify tolerant cultivars for salt stress and permit to restore soil fertility and increase yield in coastal areas in Cameroun througth culture of Granada tolerant’s cultivar for salt stress.
Utilization of Marginal Soils with Application of Phosphorus and Ethephon for...Agriculture Journal IJOEAR
— Abundance of marginal soils is among the major constraint to achieve high yield for crop production due to unsuitable physical and chemical properties of the soils. Commonly, farmers would manage the marginal soil by adding soil amendment, compost and fertilizer which increase the cost of production. Alternatively, application of fertilizer together with plant growth regulator (PGR) during crop management can be practiced to utilize the marginal soil effectively. The aim of this experiment was to determine effects of phosphorus (P) fertilizer and PGR namely ethephon on growth performance of sweet corn grown in three marginal soils namely Rasau, Kuah and Dampar. The treatments were arranged as factorial randomized complete block design with four rates of P fertilizer and standard rate of ethephon replicated four times. The results indicated that the physical properties of the marginal soils vary which Rasau dan Kuah series have low content of silt (10.30% and 36.10%), respectively and clay (9.40% and 11.86%) while Dampar series has low sand content (21%). Consequently, Dampar series depicted highest soil moisture content (18.80%) compared to Rasau and Kuah with high content of silt and clay at 42.43% and 36.43%, respectively. At tasseling stage, where application of P fertilizer with combination of ethephon at 0 and 15 kg P 2 O 5 ha-1 there were significant difference between soil series on root length, total biomass wet and dry weight but exception for total biomass dry weight at 0 kg P 2 O 5 ha-1. Moreover, at 45 kg P 2 O 5 ha-1 there were significant difference among soil series on leaf number and total biomass dry weight whereas at highest P rate of 60 kg P 2 O 5 ha-1 only root length and root volume were affected. Most of the results were observed highest on Rasau soil series which contain highest sand particle instead of silt and clay compared to Kuah and Dampar series. However, the addition of ethephon and several P rates did not affect plant height among soil series. The results suggest that, the marginal soil can be utilized for sweet corn production by addition of combined P fertilizer at low rate and PGR.
Physiological Quality of Bean Seeds Related To Azotobacter spp. InoculationIOSRJAVS
Research aimed at improving the quality of crops. The results obtained with seed coating were very influential with regard to fertilization and disease resistance. Nitrogen fertilization increases costs in agricultural production and the loss of fertile lands, altering the natural conditions and has negative consequences for the microorganisms (MO), which regulate the balance between quality of crops and soils. The biological nitrogen fixation (BNF) consists on MO work which provide nitrogen in soil and secrete substances that promote plant growth, these can be made by inoculation of seeds. The germination rate, emergency and vigor are an indicator that determines the productivity and physiological quality of a plant variety. The germination rate, number of emerged seeds per pot in favorable field conditions and vigor by accelerated aging test were evaluated. The seed treatments were: the seed inoculation with Azotobacter spp., Immersion in nutrient broth without bacteria, sterilization and zero handling. The experiment has shown that inoculation of common bean seeds with Azotobacter spp. does not adversely affect germination, emergency or vigor and stimulate the development of abnormal seedlings.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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.

1. Enhancing Soil Health and Crop
Producitvity using Artocarpus
heterophyllus (Jackfruit) Seeds as a Soil
Amendment in Sustainable Agriculture
DURON’S GROUP
3. Null Hypothesis
There is no significant difference in soil acidity level, NPK content
and plant growth parameters between the control group and the
groups treated with different concentrations of Artocarpuss
heterophyllus seeds as a soil amendment.
5. Scope and Limitations
The main focus of this study is to determine how unhealthy soil
that causes low crop production affects the community, how they
affect people and farmers, and how to enhance the soil and crop
productivity. The researcher will focus on the soil‘s acidity level,
Nitrogen, Phosphorus, Potassium level and plant growth parameters
other types of factors that can prove the soil health and productivity
will be excluded.
6. Scope and Limitation
In addition, only 10 seeds, 15 seeds, 20 seeds of jackfruit seeds
will be used to determine what concentration will be more attractive to
enhance soil health and crop productivity. The researcher will only test
soil that are found in Gensan.
