“…Therefore, rice production would be major concern in recent years due to changing climatic conditions, because significant reduction in rice yield may occur due to fluctuations in these climatic parameters. According to Sarker et al (2012), the influences of maximum temperature and minimum temperature are more pronounced compared with that of rainfall. Climate, particularly rainfall, was identified as the critical determinant of the productivity of upland rice (Gupta and Toole, 1986;Nokkoul and Wijitparp, 2013;Saito et al 2006).…”

The study was conducted at Birsa Agricultural University, Ranchi during the years 2009-2013 for understanding the effect of weather variables on the yield of three direct seeded upland rainfed rice varieties viz., Vandana, BVD-109 and BVD-111 in Jharkhand. Correlation and regression methods were used to estimate the impacts of weather on rice yield. Study indicated that temperature, rainfall and sunshine hours have significant effect on the rice yield. Average minimum temperature during sowing to vegetative stage in cv. Vandana and during flowering in BVD-109 and BVD-111 showed significant negative relationship with yield. Rainfall during vegetative and grain filling stage are significantly and positively related with grain yield in all the three rice varieties. The effect of sunshine hours on grain yield of rice was comparatively higher at milk stage than the other phenological stages in all three varieties. However, the effect of sunshine hours on yield is significant during the milk stage in Vandana and BVD-111 only. Multiple regressions using critical weather parameters in critical stages of the three varieties could explain the variability in yield of Vandana, BVD-109 and BVD-111 by 92, 74 and 91 percent, respectively.

Constant research efforts have been undertaken to create and adopt soybean varieties and farming practices that would lead to more drought-tolerant crops. Given that drought-tolerant crops are more stable in terms of price and supply, private genetic companies invest in those genetic materials with the biggest market opportunities. This begs the question: has there been any indication of improvements in drought-tolerance of crops? In this study, we focus on analyzing three soybean distinct relative maturity zones in the state of Missouri and determine if and in what direction is the drought tolerance of these crops changing over time.

“…Quadir et al (2003) showed that the monsoon rainfall up to certain optimum level is favorable for Aman rice yield and harmful for rainfall beyond that optimum level. The impact of climate variables on Aman rice yield has been studied by Sarker et al (2012), Amin et al (2015), Chowdhury and Khan (2015) and Mamun et al (2015), which provide important relationship of rainfall, humidity and temperature with rice yield. All these studies have shown adverse impacts of the increase of maximum and minimum temperature and rainfall beyond the optimum requirement.…”
