Response of fenugreek (Trigonella foenum-graecum) to different RSC waters and zinc fertilization

A pot experiment on fenugreek was conducted during rabi season at cage house S.K.N. College of Agriculture, Jobner, Rajasthan. The soil was loamy sand with pH 8.4, available nitrogen 118.10 Kg/ha, available phosphorus 13.25 Kg/ha and available potassium 152.18 Kg/ha. Application of 7.5 mmol L⁻¹ RSC of irrigation water decerease the ECe of available soil Zn while, pH and ESP of soil increased significantly. The plant height, number of pods per plant, number of seeds per pod, test weight, seed and straw yield of crop, nutrient concentration viz., P, K, Ca, Mg, Zn and Fe in seed and straw significantly with all levels of RSC of irrigation water and maximum reduction was recorded with the application of 7.5 mmol L⁻¹ RSC of water whereas N and Na in seed and straw increased significantly.
