EFFECT OF BORON ON GROWTH AND YIELD OF FIELD-PEA

Abstract

A field experiment was carried out to find out the effect of boron on growth and yield of field pea (BARI Motor-3) at the farm of Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh during the period from November, 2019 to March 2020. Seven doses of boron including control was considered as treatments viz. T ; control), T 1 (0.5 kg B ha -1 ), T 2 (1.0 kg B ha -1 ), T 3 (1.5 kg B ha -1 ), T 4 0 (0 kg B ha (2.0 kg B ha

(2.5 kg B ha -1 ) and T 6 (3.0 kg B ha -1 ). This experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. All the parameters studied on growth, yield attributes and yield parameters were significantly affected due to boron doses. The maximum plant height (107.80 cm) was registered from the treatment T (3.0 kg B ha -1 ) but the T 3 (1.5 kg B ha -1 ) showed maximum number of branch plant (4.27), number of pods plant -1 (20.53), number of seeds pod -1 (6.60), 100 seed weight (13.08 g), seed yield (1732 kg ha -1 ), stover yield (1862 kg ha -1 ), biological yield (3594 kg ha ) and harvest index (48.27%) whereas the lowest result was obtained from control treatment T

(0 kg B ha -1 ). In terms of nutrients content in field pea seed, significantly highest B content (33.33 ppm) was recorded from T but the highest N content (4.81) and Mn content (102.50 ppm) were achieved from T 5 . Similarly, significantly the highest Zn content (60.12 ppm) and Fe content (164.30 ppm) was recorded from T 4 whereas the lowest N, B, Zn, Fe and Mn content were recorded from control treatment (0 kg B ha ). Regarding P, K, S, Ca and Mg content in field pea seed, non-significant variation was found among the treatments. So, from the above results, it can be concluded that application of 1.5 kg B ha -1 (T 3 ) can be treated as best treatment followed by T (1.0 kg B ha -1 ) regarding yield performance of field pea (BARI Motor-3). 3 2 -1 -1 6 -1 -1 ), T -1 5 0
