Assessment of Temperature Impact on Wheat Varieties using Info Crop Model
The present experiment was conducted at Research farm of Rajasthan Agricultural Research Institute, Sri Karan Narendra Agriculture University, Durgapura, Jobner, Rajasthan during Rabi season 2016-17 and 2017-18 using double split plot design with three replications consisting thirty-six treatment combinations, namely, main plots: irrigation levels (0.6 Etc, 0.8 Etc, 1.0 ETc and 1.2 ETc), sub plots: varieties (Raj 4120, Raj 4079 and Raj 4238) and sub-sub plots: Dates of sowing (15th Nov., 30th Nov. and 15th Dec.) treatments. The Results revealed that Info Crop model was calibrated and validated with experimental data of three wheat cultivars (Raj 4120, Raj 4079 and Raj 4238) under different dates of sowing and irrigation scheduling. The model performance was evaluated using average error (Bias), root mean square error (RMSE) Normalized RMSE (nRMSE) and index of agreement (d) and it was observed that there is a good agreement between simulated and measured durations. Based on these results it can be concluded that the model was very accurate in predicting the growth parameters like leaf area index, biomass production and yield and captured the temporal patterns of yield variability reasonably well when compared to observed field data with good accuracy (error % between10-20). It is concluded that the Info Crop model is suitable option to predict wheat yield under semi-arid conditions of Rajasthan.
Economic impact of climate change on apple in high hills of Himachal Pradesh: Ricardian approach
Horticulture is a vibrant sector of agriculture, distinguished by scale of production, commercialization and emerged as an important source of earning livelihood for small and marginal scale farmers. The knowledge about the impact of climate change on horticultural crops is limited and increasing temperatures and changing weather conditions have harmed apple production, causing serious concern in the state, further forcing apple farmers to switch towards other crops. Therefore, the present study was conducted in high hills of Himachal Pradesh to assess the economic impact of changing climatic scenario on apple cultivation. The study found that the net revenue from apple cultivation was Rs 1.73 lakh, with 11.53 per cent variation in the study area. The results of the ricardian approach reported that the positive quadratic coefficient for minimum temperature and annual rainfall implied that either more or less both climatic variables will increase the net revenue from apple. On the other hand, the negative quadratic coefficient of maximum temperature indicated that there is an optimal maximum temperature level after which net revenue decreases in both directions. Minimum temperature and annual rainfall increased net revenue by Rs 728.56 and Rs 520.08 per 10Celsius increase in minimum temperature and 1 cm increase in annual rainfall, respectively, whereas maximum temperature decreased net revenue by Rs 925.86 per 10Celsius increase in maximum temperature for apple in high hills of Himachal Pradesh.
Stability Analysis for Grain Yield and its Components in Bread Wheat (Triticum aestivum L.)
Genotype × environment interaction and stability parameters were determined for grain yield and its components by planting 52 bread wheat genotypes under normal (E1 and E3) and late sown condition (E2 and E4) during rabi 2019-20 and rabi 2020-21. The pooled analysis of variance for stability revealed that mean squares due to genotypes and environments were found highly significant for all the characters studied when tested against pooled deviation, revealed that significant variations exist among genotypes and environments. G x E interactions were found significant for all the traits studied when tested against pooled deviation, suggested that genotypes interacted significantly in different environments for all the traits studied. For grain yield per plant, genotypes AKAW 4901, K 1317 and UAS 375 recorded higher grain yield per plant and had non-significant regression coefficient as well as deviation from regression, thus, were considered as stable genotypes. Among these three genotypes, AKAW 4901 was also found to be stable for biological yield per plant, also showed stability under favourable condition for number of productive tillers per plant, number of spikelets per main spike, number of grains per main spike and flag leaf area. K 1317 was also found to be stable for 1000 grain weight, also showed stability under favourable environment for number of productive tillers per plant and biological yield per plant, and under unfavourable environment for grain filing period, plant height, spike length, number of spikelets per main spike and number of grains per main spike. UAS 375 was also found to be stable for biological yield per plant, also showed stability under favourable environment for days to 50 per cent heading, and under unfavourable environment for grain filing period, spike length and number of grains per main spike.

Nano Fertilizer Mediated Approach Nutrient Influence on Nutrient Use Efficiency, Soil Microbial Properties, Crop Productivity, Quality and Profitability of Wheat (Triticum aestivum L.) Under Typic Ustochrepts Soil of Western Uttar Pradesh
Nano-fertilizer plays an important role in improving the fertilizer use efficiency owing to their unique properties like smaller size, high specific surface area; high surface energy and high solubility in the large nutrient requirement staple food crops like wheat (Triticum aestivum L.) to meet the global food security by reducing the drastic hazards of excessive use of fertilizers. This experiment was conducted for two years 2020-21; 2021-22 of Rabi season with the aim of this study was to evaluate the effect of nano-fertilizer mediated nutrients along with the conventional fertilizers and biofertilizers on crop growth and yield of wheat.
