EFFECT OF SULPHUR AND MOLYBDENUM ON THE GROWTH, YIELD AND OIL CONTENT OF BARI SOYBEAN-5

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 2013 to April, 2014 to study the effect of sulphur and molybdenum on growth, yield and oil content of BARI soybean 5. The experiment comprised of two factors-Factor A: Levels of sulphur (4 levels); S 0 : 0 kg S ha -1 (control), S : 10 kg S ha -1 , S 2 : 20 kg S ha -1 and S 3 : 40 kg S ha -1 ; Factors B: Levels of molybdenum (3 levels)- Mo 0 : 0 kg Mo ha -1 (control), Mo 1 : 1.0 kg Mo ha -1 and Mo : 1.5 kg Mo ha -1 . The two factors experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. For sulphur, the highest seed yield (2.00 t ha -1 ) was observed from S 2 and the lowest (1.60 t ha -1 ) from S . The highest oil content (21.52%) was observed from S 2 0 2 and the lowest (16.78%) from S .The maximum concentration in seed for N (2.80%), P (0.407%), K (0.574%), S (0.327%) and Mo (0.0143%) was found from S , while the minimum concentration in seed for N (1.67%), P (0.350%), K (0.447%), S (0.268%) and Mo (0.0112%) from S 0 2 . In case of molybdenum, the highest seed yield (1.93 t ha ) was recorded from Mo 2 , whereas the lowest yield (1.70 ha -1 ) from Mo . The highest oil content (20.64%) was recorded from Mo , whereas the lowest oil content (18.21%) from Mo 0 2 . The maximum concentration in seed for N (2.61%), P (0.402%), K (0.550%), S (0.316%) and Mo (0.0138%) was observed from Mo (1.5 kg Mo ha -1 ) and the minimum concentration in seed for N (2.18%), P (0.349%), K (0.485%), S (0.286%) and Mo (0.0121%) was recorded from Mo . For the interaction effect of sulphur and molybdenum, the highest seeds yield (2.21 t ha -1 ) was found from S 2 Mo 2 , while the lowest seeds yield (1.56 t ha ) from S 0 Mo 0 . The highest oil content (23.57%) was found from S 2 Mo , while the lowest (16.25%) from S 0 Mo 0 2 . The maximum concentration in seed for N (0.261%), P (0.402%), K (0.550%), S (0.316%) and Mo (0.0138%) was observed from S , whereas the minimum for N (1.52%), P (0.334%), K (0.433%), S (0.261%) and Mo (0.0108%) from S 0 Mo 0 . It may be concluded that application of 20 kg S ha

& 1.5 kg Mo ha -1 can be more beneficial for the farmers to get maximum yield. -1 0 1 0 2 -1 Mo 2 0 2 -1
