Impact of Zinc, Boron and Molybdenum Addition in Soil on Mungbean Productivity, Nutrient Uptake and Economics

Abstract

Zinc (Zn), boron (B) and molybdenum (Mo) are essential to increase the productivity of mungbean (Vigna radiata L.) and help to maintain the soil fertility but mostly ignored. Hence, an experiment was conducted during the years of 2016 and 2017 to know the impact of Zn, B and Mo on mungbean yield, nutrient uptake, economics and soil fertility improvement. The experiments were planned in randomized complete block design including of eight treatments with three replications. The treatments were T1 = Control, T2 = Zn 2 kg ha-1, T3 = B 1.5 kg ha-1, T4 = Mo 1 kg ha-1, T5 = Zn2B1.5, T6 = Zn2Mo1, T7 = B1.5Mo1 and T8 = Zn2B1.5Mo1. The other fertilizers, N, P, K and S at 20, 20, 30 and 10 kg ha-1, respectively were used in all treatments. The results indicate that the highest seed yield (1522 kg ha-1) was obtained from T8 treatment followed by T7. The highest percent seed yield increment (51.6%) over control was achieved in T8 treatment. Most of the growth and yield contributing characters of mungbean were recorded highest in T8 treatment. The maximum nodulation (37.6) and highest amount of protein (24.3%) was also obtained from T8 treatment. The T8 treatment contributed positively to attain higher total uptake of N, P, K, S, Zn and B by mungbean. The combination of Zn, B and Mo is showed more productive compare to sole or couple use of these micronutrients. The T8 (Zn2B1.5Mo1 kg ha-1) treatment exhibited helpful effects on soil organic matter, total N, available P, Zn and B. This treatment also showed economically better on the basis of net return. Results of the present study suggest that the combination of Zn, B and Mo applied at 2, 1.5 and 1 kg ha-1, respectively could be recommended for mungbean cultivation.

Influence of molybdenum application on soil nutrient status and uptake by cauliflower (Brassica oleracea var. botrytis L.) in an Acid Alfisol soil

“…As uptake is a function of yield and higher yields were registered in the plots where Mo application was done, might have led to an increase in the potassium uptake. Similar stimulative effects of Mo application on potassium uptake were also reported by many researchers in lentil, mungbean and loquat (Islam et al, 2018;Qudus et al, 2020;Hossain et al, 2020;Ali et al, 2021).…”

“…The significant effect of Mo application in increasing the curd yield might be due to the role of Mo in phosphorus utilization which might have played a significant role in causing early maturity of the plant (Sahito et al, 2018) which prevented the curd deformation and better marketable curds compared to control. A similar experimental outcome has also been reported in cauliflower, lentil, mungbean and blackgram (Hossain et al, 2018;Islam et al, 2018;Khan et al, 2019;Qudus et al, 2020;Hossain et al, 2020;Mahesh et al, 2021).…”

“…A synergistic effect between phosphorus and Mo application might have led to the formation of anionic complexes between Mo and P, resulting in higher phosphorus uptake by the crop. The stimulative effect of Mo application on phosphorus uptake has also been reported by many researchers in lentil and mungbean (Islam et al, 2018;Hossain et al, 2020;Qudus et al, 2020).…”

“…Molybdenum cofactors participate in the active site of nitrate reductase, which plays an important role in nitrate assimilation and might have improved the utilization rate of N fertilizer (Li et al, 2017). A similar increase in the nitrogen uptake due to the Mo application was reported in many other crops i.e., broccoli, hairy vetch, lentil, mungbean and wheat (Ahmed et al, 2011;Alam et al, 2015;Pawar and Tambe, 2016;Islam et al, 2018;Hossain et al, 2020;Qudus et al, 2020;Moussa et al, 2021).…”
