GROWTH AND YIELD OF MUNGBEAN VARIETIES AS AFFECTED BY MOLYBDENUM

Abstract

A field experiment was carried out at the research field of Sher-e-Bangla Agricultural University, Dhaka during the period of March to May 2016 to study the influence of molybdenum on growth and yield of mungbean varieties. The treatments were three mungbean (Vigna radiata) varieties viz. BARI mung-5 (V ), BARI mung- 6 (V 2 ) and BU mug-4 (V ) and five molybdenum doses viz. Control (M 0 ), 2g/kg seed (M 1 ), 4g/kg seed (M 2 3 ), 6g/kg seed (M 4 ) and 8g/kg seed (M ). The experiment was laid out into Split-plot design with three replications where varieties were assigned in the main plot and molybdenum in the sub-plot. The purpose of this experiment was to evaluate variations between the mungbean varieties developed by two different institutions and to study the possibility of increasing yield by molybdenum application. Data on different yield contributing characters, growth and yield were recorded. Interaction between varieties and molybdenum showed a positive impact on growth, yield and yield attributes of mungbean. Varieties showed no significant variations on plant height, number of nodules plant -1 , dry weight, number of pods plant -1 , number of seeds pod , first flowering, pod yield, seed yield, husk yield, stover yield, biological yield and harvest index. Pod yield, seed yield, husk yield, stover yield, biological yield and harvest index was unaffected by molybdenum application. Interaction between variety and molybdenum doses significantly influenced pod yield, seed yield, stover yield, biological yield and harvest index of mungbean. Seed yield (1210.83 kg/ha), stover yield (3338.00 kg/ha), biological yield (4.55 t/ha) was higher in V 3 M 1 treatment and harvest index was higher in V 1 M teatment. It may be concluded that interaction between variety and molybdenum doses had a significant influence on the growth and yield of mungbean.
