S. persica is a preferential halophyte, evergreen multipurpose tree species grows widely on arid salt affected lands in Rajasthan,Gujarat, Haryana and Punjab states of India (6.73 M ha). Realizing the potentials, management practices viz., Farm yard manure,gypsum and nitrogen, for its establishment were worked out earlier. Experimental site is located on a hummocky, sandy plain. Soilsare coarse sandy to loamy sand, underlain by hard, compact, pan of calcium carbonate at 75-100 cm depth. The substratum isimpervious to roots and water. Incremental tree growth was minimal after ten years. Thirteen fertilizer combinations consistingof control, FYM, N, P K and Zn were applied in Random Block Design in three replications in January, 2009. After three yearsall the treatments recorded better incremental growth as compared to control. Phosphorus application with FYM either alone orw 12 2 4 9ith other inorganic fertilizers was most effective. Maximum height increment was 35.9 in T (FYM + K SO + SSP) and T13 2 4 4 12 9 6(FYM + Urea + SSP) treatments, crown growth in T (FYM + K SO + SSP + Urea + ZnSO ), T , T , and T (FYM + SSP)12 13, 11 4 6treatments (ranging from 40 to 51). For collar girth, four treatments T , T T (FYM + ZnSO + SSP) and T recording morethan 50 incremental growth contain phosphorus either alone or with other elements. Fruit yield was influenced by rainfall also.After deficient monsoon, the mean fruiting was observed in 24.2 trees only in April, 2010. Zinc application influenced the fruity 4 7 13 3ield and per tree yield was more in T (341g), T (334g) and T (243.7g) followed by in T (123g). After above average monsoon1 2 11 12(562 mm), mean fruiting tree percentage was 49.5 (nil –T to 77.8 in T and T treatments) in 2011. T was the best treatment13 8recording maximum overall fruit yield of 1.25 kg (207 g/tree) closely followed by T (1.20 kg; 240 g/tree) and T (1.10 kg;353g/tree), respectively indicating the positive influence of Potassium with Phosphorus. While most trees have mixed colored(purple, white and pink) fruits, few trees yielded only white colored fruits every year.
