Impact of weather on rice – A review
V Sridevi, V Chellamuthu
Climate chooses the right crop for a particular environment, while the prevailing weather condition of that environment decides the potentiality of that crop. Among the crops, rice is a sensitive crop that depends highly on weather condition. Among the abiotic stresses, weather plays the dominant role in influencing the growth and yield of rice. If water is not the limiting factor, the most important weather parameters are temperature and solar radiation. Rainfall (spatial and temporal variation) is the direct critical weather parameter in rainfed ecologies. When considering the growth stages of rice, reproductive and ripening stages are the most sensitive stages to weather. Spikelet fertility is the most sensitive yield component when rice is subjected to stress viz., low or high temperature, low solar radiation or water deficit (drought). Adjust the cropping schedule to reduce the risk of unfavorable weather condition during the reproductive and ripening stages. For obtaining high yields, each and every phenophase of rice should enjoy the favourable weather conditions so as to put forth the best performance in obtaining the genetic yield dictated. The review is mainly confined to the influence of weather elements during different phenophase on growth, yield components and yield of rice.
