EFFECT OF BORON AND MOLYBDENUM ON GROWTH AND YIELD OF BARI MOTORSHUTI-1

Abstract

The experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from November 2012 to March, 2013 to study the effect of boron and molybdenum on growth and yield of BARI motorshuti-1. The experiment comprised of two factors-Factor A: Levels of boron (4 levels); B 0 : 0 (control), B 1 : 1.0 : 1.5 and B 3 : 2.0 kg B ha -1 ; Factors B: Levels of molybdenum (3 levels)- Mo : 0 (control), Mo 1 : 1.0 and Mo 2 : 1.5 kg Mo ha -1 . The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. For boron at 25, 35, 45, 55 and at harvest, the tallest plant (16.23, 38.54, 63.09, 76.60 and 82.54 cm, respectively) was recorded from B , whereas the shortest plant (14.42, 36.24, 57.97, 72.67 and 75.56 cm, respectively) from B 3 . The longest pod (8.29 cm) was observed from B 3 0 , while the shortest pod (7.31 cm) from B . The highest seed yield (7.61 t ha -1 ) was observed from B 3 and the lowest (6.28 t ha 0 -1 . The highest stover yield (13.08 t ha -1 ) was found from B , whereas the lowest (10.38 t ha -1 ) from B 0 3 0 , B 2 ) from B . The maximum concentration in seed for N (0.451%), P (0.308%), K (0.370%), B (0.0348%) and Mo (0.0133%) was found from B , while the minimum concentration in seed for N (0.374%), P (0.228%), K (0.307%), B (0.0261%) and Mo (0.0104%) from B . For molybdenum, at 25, 35, 45, 55 DAS and at harvest, the tallest plant (15.63, 38.70, 62.55, 77.50 and 82.32 cm, respectively) was found from Mo 2 0 , while the shortest plant (14.71, 36.08, 59.12, 72.95 and 78.14 cm, respectively) from Mo . The longest pod (8.38 cm) was recorded from Mo 2 (1.5 kg Mo ha -1 0 3 ) and the shortest pod (7.39 cm) from Mo . The highest seed yield (7.35 t ha -1 ) was recorded from Mo 2 0 (1.5 kg Mo ha ), whereas the lowest (6.59 t ha -1 ) from Mo 0 . The highest stover yield (12.69 t ha ) was observed from Mo 2 , while the lowest (11.03 t ha -1 ) from Mo . The maximum concentration in seed for N (0.452%), P (0.299%), K (0.365%), B (0.0356%) and Mo (0.0131%) was observed from Mo 2 (1.5 kg Mo ha -1 0 ) and the minimum concentration in seed for N (0.380%), P (0.234%), K (0.316%), B (0.0259%) and Mo (0.0106%) from Mo . Due to the interaction effect of boron and molybdenum at 25, 35, 45, 55 DAS and at harvest, the tallest plant (17.31, 40.57, 65.49, 80.34 and 85.58 cm, respectively) was recorded from B 0 3 Mo and the shortest plant (13.22, 34.79, 57.01, 68.67 and 71.19 cm, respectively) from B pod (8.94 cm) was recorded from B 3 Mo 2 2 0 Mo , whereas the shortest pod (7.05 cm) from B 0 Mo 0 . The highest seed yield (8.29 t ha -1 ) was found from B , while the lowest seed yield (6.14 t ha -1 ) from B 0 Mo . The highest stover yield (14.51 t ha -1 ) was observed from B 3 Mo 2 0 and the lowest (10.14 t ha -1 0 -1 0 -1 . The longest ) from B . The maximum concentration in seed for N (0.0497%), P (0.384%), K (0.419%), B (0.0409%) and Mo (0.0151%) was observed from B 3 Mo , whereas the minimum concentration in seed for N (0.350%), P (0.223%), K (0.305%), B (0.0252%) and Mo (0.0093%) was found from B Mo ha -1 0 Mo 0 2 . Combination of 1.5 kg B ha can be more beneficial for the farmers to get maximum yield and as well as economic return from the cultivation of BARI Motorshuti-1. 3 Mo 0 -1 2 Mo 0 & 1.0 kg
