Effect of different levels of boron on growth and yield of mungbean (Vigna radiate (L.) Wilczek) under guava (Psidium guvajava L.) Based agri-horti system in Vindhyayan region

Abstract

The present investigation entitled “Effect of different levels of boron on growth and yield of mungbean (Vigna radiata (L.) Wilczek) under guava (Psidium guvajava L.) Based agri-horti system in Vindhyayan region” was conducted during the Kharif season of 2017-2018 at Agricultural Research Farm, R.G.S.C. (BHU), Barakachha, Mirzapur (U. P.). The experiment was conducted in 10 years old guava orchard. The experiment was laid out in randomized block design having seven level of boron (B) with recommended dose of fertilizer (20 N, 40 P and 20 K ) kg /ha i.e. control, N20 + P40 + K20 + 1.0 kg B /ha, N20 + P40 + K20 + 2.0 kg B /ha, N20 + P40 + K20 + 3.0 kg B /ha, N20 + P40 + K20 + 4.0 kg B /ha, N20 + P40 + K20 + 5.0 kg B /ha and N20 + P40 + K20 + 6.0 kg B /hatreatments were replicated thrice. Results revealed that application of N20 + P40 + K20 + 6.0 kg B /ha recorded significantly higher value of the growth parameters viz. plant height (cm), dry matter accumulation (g plant-1) trifoliate leaves, branches plant-1 and root nodules plant-1 as well as yield and yield attributes like pods plant-1, number of grains pod-1, 1000-grains weight and yield of grain and stover (kg /ha) and economics viz. gross income (₹ 103924.7 ha-1), Net return (₹78205.74 ha-1), it’s found statistically at par with N20 + P40 + K20 + 5.0 kg B /ha and N20 + P40 + K20 + 4.0 kg B /ha. The treatment N20 + P40 + K20 + 6.0 kg B /ha under agro climatic conditions of Vindhyan region of Mirzapur was markedly enhanced the yield and net return of mungbean as compared to control under guava based agri-horti system.
