“…Shoot length was reduced in water stress regimes; it might be because of the difference in genetic makeup of both varieties along with insufficient availability of essential nutrients under water-stress. These outcomes are in conformity with the findings of Sarwar et al (2010) stating significant relationship between varieties and levels of irrigation. Application of FYM increased shoot length of wheat (Sharma et al 2005).…”

Crop growth is negatively influenced under water-stress conditions, which is among the most yield-limiting factors significantly decreasing crop yield. This study evaluated the effect of water-deficit stress on physiological, bio-chemical and yield attributes of wheat (Triticum aestivum L.) under both constantly wet and water-stressed conditions on two wheat varieties (UJALA-14, SARC-4). Further, the combined impacts of crop genetic variability and organic manuring in soil was studied for overcoming the partial drought stress in wheat. Treatments of different levels of irrigation water alone or with farmyard manure (FYM) @ 20 Mg ha‒1 were compared as: constantly wet irrigation (control), irrigation intensity equal to field capacity (FC), ½ FC + FYM, and ¼ FC + FYM. Crop growth, physiological and chlorophyll as well as sodium and potassium contents were measured. The findings of current study exhibited that shortage of water had negative effects on growth, physiological, bio-chemical and yield attributes of wheat. Genotype SARC-4 exhibited superior growth response having constantly wet and field capacity condition, on the other hand UJALA-14 gave better growth response under water stress conditions of ½ FC and ¼ FC when treated with FYM amendment. It is concluded that partial drought stress developed tolerance in wheat genotypes particularly in UJALA-14, which was strengthened with organic amendment. Combined use of drought tolerant varieties and application of FYM as a fertilizer is very effective way to enhance crop yield.

“…Irrigation at critical stages resulted in highest seed yield in rice whereas yield of wheat was highest with irrigation at 1.0 CPE. These results are in line with findings of Sarwar et al, (2010). The high seed yield of rice in inorganic management in the first year may be owing to the fact that inorganic fertilizers release nutrients instantly and in readily available forms for the plants during its growth, development and reproductive phase when the nutrient demand is at its peak.…”

A field experiment was conducted during rainy (kharif) season of 2018–19 and winter (rabi) season of 2019–20 at the Water Management Research Farm of CSK Himachal Pradesh Agricultural University, Palampur, Kangra, Himachal Pradesh to study the effect of moisture and nutrient management practices on different soil microbial entities and crop yields in rice (Oryza sativa L.)–wheat (Triticum aestivum L.) system. Experiment was laid out in a split-plot design with 3 replications. Treatments comprised of 3 irrigation levels, viz. Recommended critical stages regimes; Irrigation at 0.8 CPE (cumulative pan evaporation) (rice) and 0.6 CPE (wheat); Irrigation at 1.0 CPE (rice) and 1.0 CPE (wheat) assigned to main-plots and 4 nutrient management practices, viz. Inorganic; Organic; Natural farming; and Integrated management allotted to sub-plots. Irrigation at critical stages resulted in significantly higher rice yield, bacterial, azotobacter, phosphate solubilizing bacteria (PSB), actinomycetes population. However, fungi population increased under higher moisture regimes. In case of wheat crop, irrigation at 1.0 CPE resulted in a significantly higher yield (7.5% higher over irrigation at critical stages) in both the years of study. Organic and integrated nutrient management practices being statistically at par with each other recorded significantly higher microbial population. A significantly higher fungi population was, however, recorded with natural farming. The highest crop yields were obtained with integrated nutrient management (3.4 t/ha rice and 3.6 t/ha wheat in second year). The best combination for rice was irrigation at critical stages along with integrated nutrient management. Whereas, for wheat irrigation at 1.0 CPE with same nutrient management proved to be the best. Hence it is recommended to follow integrated nutrient management and irrigation at critical stages in rice and at 1.0 CPE in wheat for higher productivity as well as for improved biological properties of soil.

“…The differences in days to heading among genotypes across environments were due to genetic variability and the environment has no influence on genotypes performance. Results of this study were supported by [9,11] also reported significant differences for days to heading, while non-significant interaction results validated the findings of [9,8]. The correlation results were supported by the finding of [12], who investigated a non-significant positive correlation between days to heading and grains spike -1 , a non-significant negative correlation between days to heading and plant height, while in contrast to the present results a positive and significant correlation between days to heading and spike length.…”

“…Soil moisture not only affects physiochemical activities of a plant but also regulates the translocation of plant nutrients to various organs. Hence, adequate and timely irrigation is one of the most important cultural practices that should be considered necessary for successful crop husbandry [8]. The screening of elite and exotic wheat germplasm for drought tolerance is desirable to boost up grain yield [9].…”

Wheat (Triticum aestivum L.) is an important crop also known as the king of cereals and consumed as a staple crop by one-third of the global population. However, wheat production under rainfed conditions is restrained by water scarcity. The experiment was conducted to evaluate wheat breeding lines for yield. Fifteen F 4:7 bread wheat lines along with two check cultivars Tatara and AUP-5008 were tested in RCB design in three replications under irrigated and rainfed conditions. Analysis of variance showed significant (p<0.01) differences among the genotypes for days to heading, plant height, spike length, grains spike -1 , grain weight spike -1 , 1000-grains weight and grain yield while nonsignificant for rest of the traits. Genotype by environment (GE) interaction was significant (P<0.05) for grain yield and non-significant for the remaining traits.1000-grains weight showed positive significant
