EFFECT OF BENZYLEAMINOPURINE (BAP) AND PK ON GROWTH AND YIELD OF SUMMER MUNGBEAN (BARI mung-6)

Abstract

The experiment was conducted at the research field of Sher-e-Bangla Agricultural University, Dhaka during the period from April to June, 2017 to study the effect of benzyleaminopurine (BAP) and PK on growth and yield of summer mungbean (BARI mung-6). In this experiment, the treatment consisted of four doses of BAP viz. B 0 = 0 ppm BAP, B ii

20 = 20 ppm BAP, B = 40 ppm BAP and B = 60 ppm BAP and three different doses of PK viz. F 0 60 =Recommended dose of NPK, F =Recommended dose of N+ 125% recommended dose of PK, F 2 1 =Recommended dose of N+ 150% recommended dose of PK. The experiment was laid out in a two factors randomized complete block design (RCBD) with three replications. Data on different growth parameters and yield contributing characters of mungbean were recorded. The collected data were statistically analyzed for evaluation of the treatment effect. A significant variation among the treatment was found while different concentration of BAP and PK were applied. The maximum plant height was recorded with the dose of 20 ppm BAP. The maximum leaf length and leaf breadth were recorded with the dose of 20 ppm BAP. Among the different doses, 20 ppm BAP ha -1 showed the highest number of pods plant . The maximum seeds pod -1 , thousand seed weight (56.56 g) were recorded from 20 ppm BAP. The 20 ppm BAP was observed in the highest seed yield of 1.00 t ha -1 . The maximum plant height was observed from recommended dose of N+ 125% recommended dose of PK treatment. The highest leaf length and leaf breadth were recorded from recommended dose of N+ 125% recommended dose of PK treatment. The maximum number of pods plant -1 was recorded from recommended dose of N+ 125% recommended dose of PK. Recommended dose of N+ 125% recommended dose of PK showed the highest number of seeds pod -1 , weight of 1000 seed. The highest seed yield (1.00 t ha ) was recorded from recommended dose of N+ 125% recommended dose of PK. The highest seed yield 1.13 t ha -1 was obtained from 20 ppm BAP and recommended dose of N+ 125% recommended dose of PK.
