Abstract
A study was conducted with four traditional photosensitive and one high yielding rice varieties grown during the kharif season under rainfed conditions. The curvilinear technique was used to examine the influence of meteorological parameters on the yield of rice. Rice varieties grown in different agroclimatic regions performed differently to climatic parameters. The maximum yield was observed when rainfall ranged between 100 and 115 cm. Maximum and minimum temperature ranges of 29–32°C and 23–25°C respectively appear ideal for optimum yield. Photoinsensitive high yielding variety performed well even at low light intensity (250-350 hours of bright sunshine).
