This document summarizes research on the impacts of late sowing and heat/drought stress on wheat crops in Nepal. It finds that late sowing, which is common due to the rice-wheat cropping system, reduces wheat yields significantly. Heat and drought stress during flowering and grain filling also limit yields. The document outlines several mitigation strategies, including advancing the planting date using no-till methods, growing early maturing varieties, using mulching and irrigation scheduling, and developing heat/drought tolerant wheat varieties.
“Seed priming is a controlled hydration technique in which seeds are soaked in water or low osmotic potential solution to a point where germination related metabolic activities begin in the seeds but radical emergence does not occur.”
Modern agriculture has been largely successful in meeting the food needs for ever increasing population in developing countries. On the contrary, malnutrition, especially Fe and Zn continue to pose a very serious constraint not only to human health as well economic development of nation that might formerly have got unnoticed. Besides, the micronutrient deficiencies are becoming increasingly common in agriculture as a result of higher levels of removal by ever-more-productive crops combined with breeding for higher yields, at the expense of micronutrient acquisition efficiency (Havlinet al., 2014).Therefore, agriculture must now focus on a new paradigm that will not only produce more food, but deliver better quality food as well.

Mechanisms of adaptation to drought and waterlogging in Brachiaria grassesCIAT
Drought and waterlogging are major abiotic stresses that limit the productivity of Brachiaria forage grasses. Little attention has been given to separate productivity under drought or waterlogging, from coping mechanisms in Brachiaria forage grasses. Wide phenotypic variation exists among Brachiaria grasses to cope with these stresses. This presentation will cover : 1) the current knowledge of morpho-physiological mechanisms and functional adaptations of Brachiaria spp cultivars to cope with these stresses and 2) the use of sensors and digital image analysis for the non-destructive and automated analysis of Brachiaria growth and performance at different time scales.

This topic gives the wide range in understanding the advances for managing the abiotic stress that occurs in the pulse crops like pigeonpea,mungbean,chickpea etc.
Being sessile, plants are constantly exposed to changes in temperature and other abiotic stress factors. The temperature stress experienced by plants can be classified into three types: those occurring at (a) temperature below freezing (b) low temperature above freezing and (c) high temperature. The plants must adapt to them in other ways. The biological substances that are deeply related to these stresses, such as heat shock proteins, glycine betaine as a compatible solute, membrane lipids etc.and also detoxifiers of active oxygen species, contribute to temperature stress tolerance in plants. Rapid advances in Molecular Genetic approaches have enabled genes to be cloned, both from prokaryotes and directly from plants themselves, that are thought to provide the key to the mechanism of temperature adaptation (Iba et al., 2002).
The accumulation of heat shock proteins under the control of heat stress transcription factors is assumed to play a central role in the heat stress response and in acquired thermotolerance in plants (Kotak et al., 2007). The pattern of protein synthesis during cold acclimation is very dissimilar to the heat shock proteins in many ways. Different low temperature stress proteins, such as Anti-freeze proteins or thermal hysteresis proteins (THPs) and cold shock domain proteins etc. are accumulated in plant cell and are frequently correlated with enhanced cold tolerance ( Guy, 1999).
The heat stress-induced dehydrin proteins (DHNs) expression and their relationship with the water relations of sugarcane (Saccharum officinarum L.) leaves were studied to investigate the adaptation to heat stress in plants (Wahid and Close, 2007). In order to get an in vitro evidence of Hsc70 functioning as a molecular chaperone during cold stress, a cold-inducible spinach cytosolic Hsc70 was subcloned into a protein expression vector and the recombinant protein was expressed in bacterial cells. Results suggest that the molecular chaperone Hsc70 may have a functional role in plants during low temperature stress (Zhang and Guy, 2006). To analyze the least and most strongly interacting stress with Hsps and Hsfs, a transcriptional profiling of Arabidopsis Hsps and Hsfs has been done (Swindell et al., 2007).
As plants receive complex of stress factors together, therefore in future research, emphasis should be placed on such cases where tolerance is attempted to different stress factors simultaneously by employing sophisticated techniques.

Effect of different Mulching Materials on the Yield of Quality Protein Maize ...Agriculture Journal IJOEAR
— Field research was conducted on the effects of different mulching materials on the yield of Quantity protein maize which include polythene sheet, dry grasses and control. The different mulching materials were tested on nine (9) ridges each measuring 10m. The research was laid out in a completely randomized block design each treatment replicated three times. The parameters measured include weight of cobs, weight of 100grain, and total grain, there was no statistical difference in the weight cobs among all the treatments, similarly, there was also no statistical different in the weight of 100 grain. As far the weight of grain per 5m 2 there was a significant difference among the treatments with polythene sheet covered plots that have 0.25kg, however, the grass-mulched plots 0.16kg was statistically similar to the control plots 0.15kg. And finally for store weight observed per 5m 2 , polythene sheet covered plots were significantly higher than grass-mulched plots which are also significantly different to control plots with the values of 1.23kg, 1.21kg and 0.71kg respectively.

A field experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA) farm
Mymensingh, Bangladesh during the irrigated ecosystem in December, 2009 to May 2010, with a view to study
the performance of aromatic fine rice under different date of transplanting. The experiment was carried out with
four aromatic fine rice (V1= Chinisagar, V2= Chiniatab, V3= Basmati, V4=Awnless Minicat) and three different
date of transplanting (D1=20 January, D2=5 February, D3=20 February). The experiment was laid out in splitplot
design with three replications assigning four varieties in the main plot and the three different transplanting
dates in the sub plot. Aromatic fine rice and dates of transplanting individually showed significant effect on the
agronomic parameters. Among the aromatic fine rice Awnless Minicat gave the highest yield (3.10 t ha-1
) but
that was at per with those of Basmati (1.77 t ha-1
). Transplantation on 20 January gave the highest grain yield
(2.41 t ha-1 ) which was at per with the transplantation on 5 February (1.99 t ha-1 ).The result revealed that 20 January and 5 February produced highest grain yield by all the variety. In later date of transplanting 20 February produced lower grain yield.
Rice Drying, Storage and Processing: Effects of Post-Harvest Operations on Gr...YasirAbbas348011
Various post-harvest processes of rice are commonly employed, especially during the
off-season, to ensure its consumption feasibility, which often affect the grain quality. Different forms of
drying, storage and processing of rice are evaluated to identify their effects on grain quality. Microwave
drying has emerged as an alternative to the widely-used intermittent-drying and fixed-bed-dryer methods
of drying paddy rice. Control of drying-air temperatures (between 40 ºC and 60 ºC) according to the rice
variety can improve quality, especially for exotic varieties. Keeping stored grain in hygroscopic balance,
with water content between 11% to 15%, at temperatures between 16 ºC and 20 ºC and with intergranular
relative humidity near 60%, allows 12 months of storage in a controlled environment without significant
deterioration. Other innovations, notably the application of artificial refrigeration to grain stored in bulk in
vertical cylindrical silos and the use of impermeable packaging for storage, ensure the conservation of
grain mass. The different stages and equipments used to obtain polished, brown and parboiled rice result
in significant changes in the nutritional value of rice because of the removal of the outermost layers of the
grains. Polishing reduces the nutritional value and physical homogeneity of rice. Brown rice retains more
bioactive compounds and nutrients because it does not lose the outer layer of the grains in the polishing
processes. Parboiled rice, although less nutritious than brown rice, has better grain integrity and milling
yield and less loss of nutrients than white rice.
Growth and Yield Response of Bread Wheat Variety Grown Under Varying Seed Rat...Premier Publishers
Wheat is among the most important staple crop globally. However, constrained by appropriate agronomic practices. Therefore, the information on the interaction effect of seed rate and weeding period is useful to identify the effective time of weeding for high yield of wheat. Thus, the present study conducted at Amuru district of Horro Guduru Zone, Ethiopia in 2019 cropping season with the aim of identifying optimum seed rate and appropriate time of weeding to improve production and productivity of bread in the area. The experiment was laid down in randomized complete block (RCB) design with three replications. The treatment was arranged in factorial combinations of four weeding intervals (farmer practice, weeding at two weeks after emergence, three weeks after emergence and four weeks after emergence) and three levels of seed rate (125 kg, 150 kg and 175 kg-1).The result showed that days to 50% heading, days to maturity and effective tillers per plant were highly significantly (p<0.01) affected by the interaction effect of weeding time and seed rate. Moreover, interaction effect of weeding time and seed rate was significantly (p<0.01) affected the weed above ground dry biomass. Guizotia scabra (22.47%) with population density (370), Phalaris paradoxa (22.10%) with population (364), Plantago lanceolata (18.58%) with population density (306), and Bidens piloso L. (8.74%) were the dominant weed species competing with wheat in the study area. Minimum relative weed density (26.6%) weed dry biomass (1.7gm) and maximum weed control efficiency (98.08%) was recorded at weeding four weeks after emergence and 175kgha-1seed rate. Thus, the finding suggest grain yield was increased (52.3%) when weeding four weeks after emergence over farmers practice and 13.75% at 175kg seed rate.

The study was conducted to determine influence of cowpea and soybean intercropping pattern and time of planting on yield and Gross Monetary Value (GMV) of sorghum. The treatments were included two legume crops, two time of planting, three planting patterns of legumes and sole crops (sorghum, soybean and cowpea). The experiment was conducted in randomized complete block design with three replication. Sorghum/soybean cropping system reduced sorghum grain yield by 23.9% where as sorghum/cowpea reduced by grain yield by 40.3%. The highest LER (1.55) and the lowest LER (1.19) was recorded in sorghum/soybean and sorghum/cowpea intercropping system. Highest gross monetary benefit (20561 Ethiopian birr) accrued from planting two rows of cowpea with the first weeding of sorghum in between the two rows of sorghum. However, it was at par with simultaneous planting of cowpea in double alternate plants within sorghum plants along with two rows of cowpea in between sorghum rows and two rows of soybean planted in between two rows of sorghum with first weeding of sorghum. Legumes crop soybean and cowpea should involved in sorghum cropping either simultaneously planting or sowing at first weeding or hoeing of sorghum.
Effect of conservation agriculture on soil moisture content and biomass water...Innspub Net
One of the important principles of Conservation Agriculture is the permanent soil cover with crop residues which enhances soil and water productivity that leads to improved agricultural productivity. The effect of crop residues on soil moisture content, relative growth rate and biomass water productivity were examined in a completely randomized design at the University of Reading, Berkshire district, England. Straw treatment was significant on moisture content and water use efficiency at (p< 0.01) respectively while there is no significant difference on mean relative growth rate and dry final biomass weights. The study concluded that soil moisture content is conserved with increased use of crop residues as soil cover. The study therefore recommended that project based research on Conservation Agriculture should be carried out by governments and NGO’s that will involve farmers; also they should provide support for the knowledge diffusion of Conservation Agriculture to local farmers since it will improve yield and productivity. Extension agents and other agencies that work with farmers should also be properly trained to be able to disseminate this technology to farmers.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola

There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

6. Results and Discussions
Importance of sowing date
Early sowing provides longer period of maturation, earlier flowering and
higher yield potential (Coventry et al.,??).
Wheat in Nepal is generally sown in November to late December and
harvested in March/April (Joshi et al.,2006).
Timely planting of wheat is often delayed by tillage and yield potential is
also reduced. This is due to rice crop vacating the field late (Hobbs et
al.,2005; Gupta et al.,2010).
With delay in sowing time from 1st fortnight of November to 1st fortnight of
December, a decline in yield at 32 kg/ha /day is reported (Tripati et
al.,2005).
A yield loss of 1-1.5% for delay of each day after the optimum sowing date
of Nov 15 in wheat crop is recorded (Hobbs et al.,2005).

How terminal moisture stress limits the
yield?
Many Scientists and researchers have reported of this drop in
grain and biomass yield is due to exposure of plant to
terminal heat and drought stress.
Terminal stress is the moisture stress mainly during dry
seasons on heavy soil, where plants are grown on stored
moisture and matures on progressively depleting moisture
profile(Ludlow & Muchow,1988).
Nirman et al., 2013 simulated and concluded that yields of
rainfed wheat was lower (1.7 t/ha) due to water stress during
the post anthesis phase resulting in early senescence during
dry years.
And wheat in case of Nepal is sown after rice and it grows
and survives on the residual soil moisture and late monsoon
rain or winter rain (Nirman et al.,2013) which is only 20% of
the annual rainfall (Malla, 2008).
As 0.8 tons of water is required to produce 1 kg of wheat
grain (Wani GM,2011),Wheat production falls short of
moisture.

13. Effect of terminal heat stress on
yield Terminal heat stress is due to mean daily temp exceeding 17.50C in
the coolest month in wheat growing region(Fischer & Byerlee,
1991).
Increase in temperature reduces crop duration, increase crop
respiration rates, reduces crop yield , increased sterility that reduced
the no. of grains formed, inhibit sucrose assimilation in grain, affect
survival and distribution of pest populations (Hundal & Kaur,2007).Change in

Rane et al.,2002 reported that thirty million hectares of crop was
affected by terminal heat stress in temperate growing regions.
In wheat, the grain filling duration continued to decrease at
temperatures above 26.7 °C.
Similarly heat induced spikelet sterility and increased in the
respiration losses from the crops during the grain filling also caused
by rising temperatures (Timsina and Humphrey,2006).
Heat stress affects the grain set if occurred during flowering and
terminal heat stress reduces number of grains, weight of grain and
grain filling duration (Chenu et al.,; Wall et al., ;Aggrawal
&Kalra,1994).
Wheat crop experiment conducted in open top chamber in NARC
showed that decrease in the growth stage like spike initiation,
heading, flowering, milking and physiological maturity by 14, 5, 9, 6
and 14 days respectively due to increase in
temperature(Malla,2008).

17. Mitigation strategies
Advancing in plant date
No-till method
A yield increase up to 41% is recorded by zero till plot over
conventional tilled due to 24 days earlier in planting date(Hobbs &
Gupta, 2003).
Planting the wheat in advance using zero-till ,sowing of the varieties
that can either adapt or escape terminal stress, using of crop
residues./mulching, wise use of irrigation (irrigation scheduling) and
plant nutrients (site specific nutrient management) are suggested as
possible solutions for combating the terminal stress in wheat production
(Jat et al.,2009).
Use of early maturing rice varieties in rice-wheat cropping system.
Cultivar choices
Use of varieties that can either tolerate heat, avoid heat or escape
drought/heat.
Early maturing varieties –Adoption of early maturing varieties showed
10% yield advantage over long duration varieties(Joshi et al.,2012).

An experiment conducted at 14 sites of various countries , Nepal(1), India
(6), Bangladesh (2), Pakistan (1)and Mexico(4), by CEISA as Heat trial-
Early maturity trial during 2009-10 showed superiority (>10%) of 10% lines
over local checks.
Stay green varieties- As there is positive association between duration of
photosynthetically active leaf area and grain yield, identification of
molecular markers for stay green trait can further open doors to fight heat
stress( Singh et al., 2012).
Using varieties with higher water-use efficiency.
Using varieties with heat tolerance traits as membrane thermostablity,
stomatal conductance and heat shock proteins (Slafer &
Whitechurch,2001).
Use of mulching-decreases evaporation and increases water availability
Irrigation management –wise use of irrigation by scheduling on critical
stages
Balanced plant nutrition
20. Conclusion
Late planting of wheat is one of the major cause for exposure
of wheat plants to terminal heat and drought stress.
Terminal stress of heat and drought affects on wheat
phenology and all yield attributing traits resulting in significant
drop in biomass and grain yield.
Use of better cultivation practice (Zero-tillage) with retention
of crop residues/mulching, selection of early maturing
varieties with better management practices and breeding
works over identification of molecular markers for heat and
drought tolerance is the future to solve the above mentioned
stress.
