India has the largest area and stand as the second largest producer of cashew in the world. During the year 2018-19 the area under cashew was 11,05,000 ha with production of 7,42,714 MT with average productivity of 707 kg ha -1 (Anon., 2019). Cashew usually grown in

Rice (Oryza sativa L.) is the second most important food in the world after wheat. Most rice is now grown in areas where the temperature is higher than the optimum growing temperature (28/22°C); therefore, a further increase in average temperature or high temperature occurring in the sensitive phase of the crop can affect growth and yield. Clutter. For every 1°C increase in daytime maximum/night minimum temperature from 28°C/21°C to 34°C/27°C, rice yield decreases by 7% to 8%. Additionally, the benefits that crops derive from high atmospheric carbon dioxide concentrations must be lost due to warming. The thermal stability of cell membranes is thought to correlate well with yield performance. Temperature is important in photosynthesis, but too hot can cause reduced photosynthesis of leaves and reduced distribution of dry matter to shoots and roots. The disadvantage of temperature is not limited to the above-ground rice. The underground area is affected, if not more, by the flood, and the temperature of the soil changes due to the heat. Future increases in global temperatures threaten people worldwide who depend on crops for their health and food security. In the past, the stress of the crisis on rice production focused on the rice crop. This review highlights the importance of rice in the world, the effect of high temperature on the growth, quality, yield and properties of rice, and the need for future research.

The available daily rainfall data of 40 years at SGCARS, Kumarawand, Jagdalpur, District Bastar was examined for long term rainfall averages on weekly basis for Kharif season and its temporal variability. Coefficient of variation of 24.14 per cent indicated that the season's weekly rainfall was more or less stable over the years. The contribution to annual rainfall was 85.57 percent during Kharif season. Within the weeks, 30 th week (23 rd July to 29 th July) was recorded as the highest rainfall contributing week with 8.16% followed by 26 th week (25 th June to 1 st July) with 7.78% of total season's weekly rainfall. Mean weekly precipitation amount and its assurance reaches the peak (>65 mm/week) during 25th SMW to 33 rd SMW which is classified as heavy rainfall and again declined thereafter. In week 28 th continuity of rainfall (<20mm) is recorded for over 39 years. There is an ample scope of rain water to cultivate crop as rainfed kharif crop and also for rain water harvesting from July to September which can be utilized as crop saving irrigation as well as pre-sowing irrigation for succeeding rabi crops which are generally sown on residual soil moisture.
