RESPONSE OF YIELD OF DIFFERENT VARIETIES OF MUNGBEAN TO GIBBERELLIC ACID

Abstract

This experiment was carried out in the Laboratory of Department of Agronomy, Hajee Mohammad Danesh Science and Technology University (HSTU), during the period from May to July 2017 to investigate the effect of GA3 on the yield and yield contributing characters of mungbean. GA3 was three levels such as 0, 50, and 100 ppm and four mungbean varieties were used such as BARI Mung 3, BARI Mung 4, BARI Mung 5 and BARI Mung 6. The experiment was laid out in a completely randomized design with three replications. The collected data were analyzed statistically and means were adjudged by DMRT at 5% level of probability. The results of the experiment revealed that significant variations existed among the varieties in respect of morphological characteristics and yield contributing characters like plant height, leaf area, plant water relations, number of pods plant-1, pod length, number of seeds pod-1, 1000-grain weight, total grain yield, biological yield and harvest index. BARI-Mung3 produced the leaf area, plant water relations, number of pods plant-1, pod length, number of seeds pod-1 , 1000-grain weight, grain yield, biological yield, harvest index and highest plant height. The Highest plant height, maximum straw yield, biggest leaf area, best of plant water relation were recorded at 100ppm of GA3 concentration. Whereas pod length, number of seeds pod-1, number of pods plant-1, 1000-grain weight, grain yield and biological yield highest at 50ppm.
