Abstract:

Rice is one of the most important food crops in the world. Rice is the mainstay of nearly 40% of the world__ampersandsign#39;s population. The planting date is critical for ensuring that the crop receives the best weather conditions possible. The duration of phenophases correlated negatively with the maximum temperature. Towards the end of the planting season, the duration is shortening. Plant height was found to have a significant positive correlation with rainfall and a significant negative correlation with temperature. Dry matter accumulation was highest on August 5th, with a positive correlation with relative humidity and a negative correlation with temperature. It was observed that rainfall during heading to 50% flowering had a negative correlation with a number of filled grains. The yield of the crop had a significant negative correlation with rainfall during the flowering to physiological maturity. The planting date is critical to ensuring that the crop receives optimal weather conditions
