EFFECT OF HIGH TEMPERATURE AT DIFFERENT GROWTH STAGES OF SHORT DURATION AMAN RICE VARIETIES (Pages : 16 - 19)

Temperature is one of the most important environmental factors influencing crop growth, development and yield processes. Temperature is becoming the major concern for plant scientists worldwide due to the changing climate. Three short duration Aman rice varieties (Binadhan-17, Binadhan-19 and Binadhan-22) were evaluated under high temperature (360C) at booting and flowering stages for 3 days along with ambient temperature. Panicle length, number of filled grain panicle-1 and 1000-grain were similarly affected by high temperature at booting and flowering stage. High temperature (360C) at flowering stage produced the highest number of unfilled grain panicle-1. Yield was significantly decreased with high temperature at flowering followed by booting stage. However, high temperature at flowering stage was found more detrimental. Binadhan-19 reduced less yield in high temperature compared to other varieties.Download
