INFLUENCE OF PHOSPHORUS AND BORON ON THE GROWTH AND YIELD OF MUNGBEAN (BAR! MUNG-5)

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm. Dhaka during the period from March, 2008 to May. 2008 to study the influence of phosphorus and boron atone and in combination on the growth and yield of BARI Mung 5 (Vigna radio/a). The experiment included thur levels of phosphorus viz.. 0. 15. 30 and 45kg Pha and four levels of boron viz.. 0.0.5. 1 and 2 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 munghean. Application of phosphorus 30 kg ha 4 produced the highest plant height. pod planC1 . pod length. seeds pod ', 1000-seed weight. stover yield except number of branches plant '. In all the cases lower values were found with the control treatment. Boron fertilizer also had significant effect on yield and yield attributes of munghean. Application of boron@ 1 kg ha 1 gave the highest seed yield, pods plant '. seeds pod* 1000-seed weight. stover yield except plant height. In all cases the lower values were Ihund with the control treatment. Phosphorus

30 kg ha 4 was found statistically superior to all other treatments. Phosphorus in combination with boron showed significant effect on yield and yield attributes of mungbean. Combined application of phosphorus @ 30 kg and boron

1 kg ha" resulted the highest seed yield, plant height, stover yield and total content of P and B by munghean. On the other hand, in all the cases lower values were found in the control treatment. The addition of P and B not only increased the yield but also protect the soil from total exhaustion of nutrients.
