Abstract

A pot experiment was conducted during kharif 2018-19 at S.K.N. College of Agriculture, Jobner (Rajasthan) to study the “Effect of Zn and Fe enriched Farmyard manure on nutrient availability and yield of cowpea [Vigna ungiculata (L.)wilczek] under sodic water irrigation” to evaluate the effect of different sodic water and sources of Zn and Fe on yield, nutrient concentration and uptake by cowpea on loamy sand soil. The experiment comprising of 15 treatment combinations replicated three times, was laid out randomized block design with three levels of sodic water (2, 4 and 6 mmol L-1 ) and five levels of sources of Zn and Fe (0, ZnSO4.7H2O, FeSO4.7H2O, Zn enriched FYM, Fe enriched FYM) as variables. The total and number of nodules per plant, nodule index, pods per plant and seeds per pod were counted at stage and harvesting respectively. Results revealed that under 6 mmol L-1 Residual sodium carbonate of irrigation water, the seed and straw yield of, nutrient concentration and uptake viz., P, K, Zn and Fe in seed and straw decreased significantly with all levels of sodic water and maximum reduction was recorded with the application of 6 mmol L-1 of sodic water, while N in seed and straw, protein content in seed increased significantly. The application of Zn enriched FYM increased seed and straw yield , nutrient concentration and uptake viz., N, P, K, Zn and Fe in seed and straw, protein content in seed.

Keywords: Sodic water, Zn enriched FYM, Fe enriched FYM, seed and straw yield, nodule index
