“…First, a positive correlation was found between grain yield and GT20 in the northern region of central China, which is different from the case in the southern region of central China. Our results also showed that GT20 had a strong positive correlation with RW in Suizhou City, while most studies showed that high temperature in grain filling stage would reduce the grain weight . These inconsistent results might be because GT20 was lower than 27 °C across most of the sowing dates in Suizhou, which was different from the situations in Wuxue.…”

“…Our results also showed that GT20 had a strong positive correlation with RW in Suizhou City, while most studies showed that high temperature in grain filling stage would reduce the grain weight. [55][56][57] These inconsistent results might be because GT20 was lower than 27 ∘ C across most of the sowing dates in Suizhou, which was different from the situations in Wuxue. Just as Tashiro and Wardlaw 34 reported, it is beneficial for grain filling when the temperature varies from 21.7 ∘ C to 26.7 ∘ C, while the temperature over 27 ∘ C would cause a decline of rice grain yield by reducing grain weight.…”

BACKGROUND Climate change has posed great challenges to rice production. Temperature and solar radiation show significant variations in central China. This study aims to analyze the responses of different rice genotypes to the variations of temperature and solar radiation in central China, and to find the way of identifying the optimal sowing date to improve and stabilize rice production. For this end, four rice genotypes (two Indica and two Japonica cultivars) were cultivated at two locations under irrigation conditions in 2 years with six sowing dates. RESULTS We investigated variations of rice grain yield, resource use efficiency, average daily temperature and solar radiation during different phenological stages. Rice grain yield could increase by about 2–17% in central China. Compared with solar radiation, temperature was a more important factor affecting rice grain yield in central China. The grain yield showed great correlation with the means temperature during different phenological stages, especially during the first 20 days after heading (GT20). Besides our results demonstrated that the grain yield displayed slender variations when the GT20 was within 24.9–26.4 °C. However, GT20 was higher than 26.4 °C in most cases, which became more frequent due to climate changes. Analysis of climate change during the last 25 years revealed that the frequency of GT20 within 24.9–26.4 °C was increased by the delay of sowing date. CONCLUSION We propose that delaying sowing date to achieve the optimal GT20 (24.9 °C–26.4 °C) can be an effective strategy to stabilize and improve rice grain yield and resource use efficiency in central China. © 2019 Society of Chemical Industry

“…Cotton main stem elongation, leaf area expansion, and total biomass accumulation were extremely sensitive to temperature about 21 days after emergence. Optimum temperature for stem elongation, leaf area expansion, and biomass accumulation was 22 to 30°C (Ziska et al 1997;Shah et al 2013). The boll size and fiber length and micronaire decreased with an increase in temperature (Conaty et al 2015).…”

This review outlines nitrogen (N) responses in crop production and potential management decisions to ameliorate abiotic stresses for better crop production. N is a primary constituent of the nucleotides and proteins that are essential for life. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment. Therefore, increasing plant N use efficiency (NUE) is important for the development of sustainable agriculture. NUE has a key role in crop yield and can be enhanced by controlling loss of fertilizers by application of humic acid and natural polymers (hydrogels), having high water-holding capacity which can improve plant performance under field conditions. Abiotic stresses such as waterlogging, drought, heat, and salinity are the major limitations for successful crop production. Therefore, integrated management approaches such as addition of aminoethoxyvinylglycine (AVG), the film antitranspirant (di-1-p-menthene and pinolene) nutrients, hydrogels, and phytohormones may provide novel approaches to improve plant tolerance against abiotic stress-induced damage. Moreover, for plant breeders and molecular biologists, it is a challenge to develop cotton cultivars that can tolerate plant abiotic stresses while having high potential NUE for the future.

“…Peraudeau et al [48] found that although night respiration increases with higher temperatures, the reduction in carbon assimilation and dry matter production is negligible with indica cultivars. Shah et al [39] observed reductions in grain yield of 0% and 10% in 2009, and 17% and 45% in 2010, for indica and japonica varieties, respectively, in a field-scale experiment involving a 2˝C increase in night temperatures. The implications of higher night temperatures on carbon assimilation and grain yields are not yet fully understood.…”

“…In areas where rainfall increases with climate change, rice yields might increase, although there might be offsetting impacts due to higher temperatures, particularly at night and during the booting, flowering, and grain-filling stages of production [10,26,38,39]. Higher humidity, in combination with higher temperatures, also can cause spikelet sterility and reduce grain quality [40,41].…”

Rice production is susceptible to damage from the changes in temperature and rainfall patterns, and in the frequency of major storm events that will accompany climate change. Deltaic areas, in which millions of farmers cultivate from one to three crops of rice per year, are susceptible also to the impacts of a rising sea level, submergence during major storm events, and saline intrusion into groundwater and surface water resources. In this paper, I review the current state of knowledge regarding the potential impacts of climate change on rice production and I describe adaptation measures that involve soil and water management. In many areas, farmers will need to modify crop choices, crop calendars, and soil and water management practices as they adapt to climate change. Adaptation measures at the local, regional, and international levels also will be helpful in moderating the potential impacts of climate change on aggregate rice production and on household food security in many countries. Some of the changes in soil and water management and other production practices that will be implemented in response to climate change also will reduce methane generation and release from rice fields. Some of the measures also will reduce the uptake of arsenic in rice plants, thus addressing an important public health issue in portions of South and Southeast Asia. Where feasible, replacing continuously flooded rice production with some form of aerobic rice production, will contribute to achieving adaptation objectives, while also reducing global warming potential and minimizing the risk of negative health impacts due to consumption of arsenic contaminated rice.
