INFLUENCE OF FERTILIZER AND PLANT POPULATION ON GROWTH AND YIELD OF SUMMER MUNGBEAN (Vigna radiata L)

Abstract

An experiment was carried out at the Agronomy Field. Sher-e-BangLa Agricultural University, Dhaka during the period from March to June, 2006 to study the influence of bio-fertilizer and plant population on growth, and yield of mungbean (Vigna radiata). The experiment consisted of two levels of treatments viz, a). inoculation (No inoculation, BINA-MB 441 and BINA-MB-THA 301)and h). plant population (10,20,30.40 and 50 plants m 2 ). The experiment was laid out in a randomized complete block design (Factorial) with three replications. The results revealed that BINA-MB 441 performed the best. The highest seed yield (1.20 t h a t), number of nodules plant", dry weight of nodules plant", number of pods plant 4 , number of seeds pod1 , weight of 1000 seeds, seed yield plant", straw yield and harvest index were attained from BINA-MB 441. Plant population also significantly influenced all crop characters studied. The results revealed that 30 plants rn'2 showed the best performance in respect of seed yield (1.25 t ha") than other plant population treatment. The highest number of nodules plant" (10.44), number of pods plant" (14.26), number of seeds pod" (30.23). weight of 1000 seeds (47.54 g) and seed yield plant" (5.61 g) were obtained from 10 plants m' whereas the highest plant height, LA! (2.31) and straw yield (3.65 t ha") were found in 50 plants rn' 2 . Combination of BINA-MB 441 with 30 plants rn'2 was found to be the best in respect of seed yield and straw yield. Combinution or I3INA-M 13 441 with 10 plants in' 2 was found the hcsL in respect of number of nodules plant" (13.32), number of pods

(16.69), number of seeds pod" (32.24), weight of 1000 seeds (50.71 g) and seed yield plant" (6.98 g) whereas significantly the highest plant height, leaf area index (2.99) and straw yield (3.97 ha") were found in B[NA-MB 441 with 50 plants rn' 2
