EFFECT OF BORON AND ZINC ON THE GROWTH AND YIELD RESPONSE OF MUNGBEAN

Abstract

The experiment was carried out during the period from March 2017 to June 2017 at the Agronomy farm of Sher-e-Bangla Agricultural University, Dhaka to evaluate the effect of boron and zinc on the growth and yield performance of mungbean (var:BARI Mung-6). The experiment comprised of two factors; Factor A: Three levels of boron - (i) B R = Recommended dose of B, (ii) B = 20% less than recommended dose of B and (iii) B = 20% higher than recommended dose of B and Factors B: Three levels of zinc - (i) Zn ii

R+20 = Recommended dose of Zn, (ii) Zn R-20 R = 20% less than recommended dose of Zn and (iii) Zn = 20% higher than recommended dose of Zn. The experiment was laid out in a randomized complete block design using three replications. Data on different growth parameters, yield contributing parameters and yield were recorded. Results showed significant variations in the growth and yield parameters due to the application of varying levels of boron and zinc; and also applying them combined. Higher values of almost all the parameters were observed with the interaction treatments B R Zn R R+20 and also with other interaction treatments having 20% higher amount of boron and zinc over the recommended dose. Significantly the highest dry weight per plant was obtained with B R+20 Zn (68.07 g). However the higher seed yields (1362-1371 kg/ha) were obtained with B R+20 R Zn R R-20 and B combination of treatments which were attributed to the higher values of number of pods per plant (23.45-24.25), number of seeds per pod (12.72-12.87) and 1000 seed weight (over 47 g) of these two interaction treatments.
