Abstract:
A field experiment was carried out at the Research farm, Department of Agricultural Chemistry, P.G. College, Ghazipur during kharif season of two consecutive years (2019 and 2020) to study the "Effect of boron and zinc on productivity of black gram (Vigna mungo L.) and fertility status of soil". The experiment was laid out in Factorial Randomized block design keeping levels of born as a factor A and levels of zinc as a factor B with three replications. kg^-1 zinc ha^-1, Zn2- 2.0 kg zinc ha^-1, Zn3- 3.0 kg zinc ha^-1, Zn4- 4.0 kg zinc ha^-1. The experiment was sown on 25th July during 2019 and 03th August during 2020 using UPU- 1 crop variety of black gram. Soil of the experimental field was sandy loam in texture having 1.52 and 1.51 Mg m-3 bulk density, 2.70 and 2.69 Mg m-3 particle density, 43.17 and 42.57% porosity, 62.01 and 63.42% water holding capacity, 0.72 and 0.73% organic carbon, 161.44 and 162.67 kg ha^-1 available N, 14.71 and 14.74 kg ha^-1 available P2O5, 240.90 and 242.57 kg ha^-1 available K, 0.139 and 0.141 mg kg^-1 boron, 0.50 and 0.51 mg kg^-1 zinc, soil pH 7.20 and 7.21 and EC 0.237 and 0.238 dsm^-1 at 0-15 cm depth of soil in respective years of experimentation. The recommended dose of fertilizers (NPK: 20:20:30 kg ha^-1) were applied uniformly in each plot. The levels of boron and zinc were applied as per treatments concluded from two years of study application of 2.0 kg boron along with 4.0 kg zinc ha^-1 enhance growth parameters yield attributes. Recommended for UPU^-1 variety of black gram under irrigated condition during kharif season in Eastern Plain Zone of Uttar Pradesh.
