EFFECT OF DIFFERENT COMBINATIONS OF PHOSPHORUS AND BORON ON GROWTH AND YIELD OF A SELECTED BARI MUNG-6

Abstract

The study was carried out at Sher-e-Bangla Agricultural University, Dhaka duringthe period from April to June of 2015 to find out the effect of differentcombinations of phosphorus and boron on growth and yield of a selected BARI Mung-6. The treatments of the experiment were laid out with RandomizedComplete Block Design (RCBD) with three replications. There were two factorsviz. phosphorus and boron. Four phosphorus levels viz. (i) P 0 = (Control), (ii) P 1 = 20 kgha -1 , (iii) P 2 = 30 kg ha -1 and (iv) P 3 = 40 kg ha -1 and four levels boron viz. (i) B 0 = (Control), (ii) B 1 = 1 kg ha -1 , (iii) B 2 = 1.5kg ha -1 and (iv) B 3 = 2kg ha wereconsidered. The experimental findings revealed that the longest plant (83.71 cm),maximum number of leaves plant -1 (23.27), maximum number of branches plant (5.86), highest pod length (10.28 cm), highest number of pods plant (35.47),highest number of seeds pod -1 (11.6), highest 1000 seed weight (38.72 g), highest grain yield (1.81 t ha -1 ), highest stover yield (2.86 t ha -1 ), highest biological yield(4.67 t ha -1 ) and the highest harvest index (38.80) were recorded from P 2 . The highest protein content (14.78%) was recorded from P 2 B 2 -1 -1 B 1 and also from P 2 (14.71%). In conclusion, P 2 B 1 (30 kg P ha -1 and 1 kg B ha -1 ) may give the

-1 B 1 maximum return in respects of yield and quality for the betterment of pulses producers and eaters in Bangladesh.
