EFFECT OF VARIETY AND FLOWER REMOVAL ON THE PERFORMANCE OF MUNGBEAN

Abstract

The experiment was conducted during the period from March to June 2013 at the farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh to study the effect of variety and flower removal at 3 intervals out of the cropping duration of mungbean. The varieties like BARI mung-3, BARI mung-4, BARI mung-5 and BARI mung-6 were used as the test crop. The experiment consists of two factors designated: Factor A (Mungbean variety 4; V : BARI mung-3, V 2 : BARI mung-4, V 3 : BARI mung-5 & V : BARI mung-6) and Factor B (Flower removal 4 levels; R 0 4 : No removal of flower, R : Removal of flower at 30-35 DAE, R 2 : Removal of flower at 40-45 DAE & R : Removal of flower at 50-55 DAE). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The tallest plant (54.05 cm) was recorded from V 4 1 3 , whereas the shortest plant (44.13 cm) was recorded from V . The maximum number of pods per plant (19.98) was recorded from V , whereas the minimum number of pods per plant (18.16) was recorded from V . The highest seed yield (1.99 t/ha) was recorded from V , whereas the lowest seed yield (1.63 t/ha) was observed from V 1 4 . The highest stover yield (2.47 t/ha) was recorded from V whereas the lowest stover yield (2.24 t/ha) was recorded from V 1 4 .The tallest plant (51.86 cm) was found from R and the shortest plant (47.96 cm) was observed from R 3 0 . The maximum number of pods per plant (21.21) was recorded from R , while the minimum number of pods per plant (16.10) was found from R 3 2 . The highest seed yield (1.92 t/ha) was recorded from R , while the lowest seed yield (1.36 t.ha) was observed from R . The highest stover yield (2.77 t/ha) was observed from R 2 3 , while the lowest stover yield (1.61 t/ha) was observed from R 3 .The tallest plant (57.85 cm) was recorded from V 4 R , while the shortest plant (41.15 cm) from V 1 R 3 0 . The maximum number of pods per plant (22.57) was recorded from V 4 R , while the minimum number of pods per plant (14.90) from V 4 R 3 2 . The highest seed yield (2.20 t/ha) was found from V 4 R , while the lowest seed yield (1.40 t/ha) from V 4 R 3 2 . The highest stover yield (3.02 t/ha) was recorded from V 4 R 2 , while the lowest stover yield (1.87 t/ha) was recorded from V . It was revealed that the combination of V 4 R appeared best in terms of yield contributing characters and yield of mungbean.
