EFFECT OF NITROGEN AND MOLYBDENUM ON THE GROWTH AND YIELD OF BARI BUSH BEAN-2

Abstract

A field experiment was carried out in Modhupur Tract (AEZ- 28) at research field of Sher-e-Bangla Agricultural University, Dhaka, during the Rabi season from November 2014 to March 2015 to study the effect of Nitrogen and Molybdenum on the growth and yield of bush bean (Phaseolus vulgares L.) cv. BARI Jhar Sheem-2. The treatments consisted of 4 (four) levels of N (0, 60, 80, 100 kg ha designated as N 0.6 kg ha -1 0 , N 60 , N 80 , N 100 ) designated as Mo respectively and 3 (three) levels of Mo (0, 0.3 and 0 , Mo 0.3 , and Mo 0.6 respectively. Urea and ammonium molybdate were used as the sources of nitrogen and molybdenum respectively. There was a positive impact on number of effective plant height number of branches plant plot -1 -1 , number of green pod plant -1 , pod length, pod yield , green pod weight, and stover yield with increasing the rate of nitrogen and molybdenum, all these parameters increased up to N green pod yield (13.40 t ha (13.07 t ha -1 -1 ) was obtained from N )) was obtained from Mo was attained in N were recorded in N 100 Mo 80 0.6 Mo 0.6 100 100 and Mo 0.6 . The highest . The highest green pod yield . The maximum pod yield (14.50 t ha treatment. The highest N, P, K and S contents in plant 0.3 found in control treatment NoMo. and N 100 Mo 0.6 treatment and the lowest result was -1 -1 -1 ) , )
