EFFECT OF PHOSPHORUS AND BORON FERTILIZERS ON GROWTH AND YIELD OF MUNGBEAN

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka during the period from September, 2013 to December, 2013 to study the effectiveness of phosphorus and boron alone and in combination on the growth and yield of BARI Mung 5 (Vig-naradiata). The experiment included three levels of phosphorus viz., 0, 20 and 40 kg P ha and three levels of boron viz., 0, 0.75, and 1,5 kg B hi'. The experiment was laid out in a Randomized Complete Block Design with three replications. Phosphorus showed significant influence on yield and yield attributes of mungbean. Application of phosphorus @ 40 kg ha produced the highest plant height, number of branches plant'. pod plani', pod length, seeds pod', 1000-seed weight, grain yield and stover yield. In all cases the lowest values were found with the control treatment. Application of boron @ 1.5 kg hi' gave the highest plant height, number of branches plant", pods plant -', seeds pod', pod length, 1000-seed weight, grain yield, and stover yield. In all cases the lowest values are found in the control treatment. Combined application of phosphorus @ 40 kg and boron @ 1.5 kg hi'resulted the highest plant height, number of branches plant', pods plant' ] , seeds pod", pod length, 1000-seed weight, seed yield (1.79 1/ha), and stover yield(2.96 ton/ha). Phosphorus and boron alon or in combined application showed significant effect on yield and yield attributes of mungbean. The addition of P and B not only increased the yield but also protect the soil from total exhaustion of nutrients.
