Abstract

A pot experiment was conducted to evaluate the effect of different RSC waters and zinc fertilization on soil properties, yield and nutrient ratios of fenugreek on loamy sand soil. The experiment comprising 12 treatment combinations replicated three times was laid out in completely randomized block design with four levels of RSC water (control, 2.5, 5.0 and 7.5 mmol L-1) and three levels of Zn (0, 10 and 20 mg ZnSO4 ha-1 soil). Results revealed that under 7.5 mmol L-1 RSC of irrigation water, the ECe, content of different fractions of soil Zn and available soil Zn was decreased significantly, while pH and ESP of soil increased significantly. The seed and straw yield of crop, P/Zn in straw and Ca/Mg ratios of seed and straw decreased significantly with all levels of RSC of irrigation water. While, Na/K, Na + K/Ca and Na/Ca ratio of seed and straw increased significantly. P/Zn and Fe/Zn ratios of seed also increased significantly. The increasing level of zinc significantly increased the seed and straw yield of crop, Ca/Mg ratio of seed and straw. While P/Zn, Zn/Fe, Na/K, Na + K/Ca and Na/Ca ratios of seed and straw decreased significantly.
