Abstract:
A pot experiment was conducted during kharif 2018-19 at S.K.N. College of Agriculture, Jobner (Rajasthan) on the “Effect of Zn and Fe enriched FYM 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 soil properties (pHs, ECe, SAR, OC and DTPA-Zn and Fe content, available N, P2O5, K2O and yield attributes of cowpea on loamy sand soil. The experiment comprising of 15 treatment combinations replicated three times, was laid out in completely 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. Results revealed that under 6 mmol L-1 RSC of irrigation water, the ECe, organic carbon, DTPA-Zn and Fe, available N, P2O5 and K2O were decreased significantly, while pH and SAR of soil increased significantly. The number of total and effective nodules, nodule index, plant height, number of pods per plant, number of seeds per plant, seed index of cowpea decreased significantly with all levels of sodic water and maximum reduction was recorded with the application of 6 mmol L-1 of sodic water. The application of Zn enriched FYM decreased the pH and SAR significantly while Organic carbon, DTPA-Zn and Fe, available N, P2O5, K2O of soil, number of total and effective nodules, nodule index, plant height, number of pods per plant, number of seeds per plant, seed index of cowpea increased significantly.
