Effect of Soil Application of Zinc Sulphate on Growth, Yield and Quality of Guava cv. L-49

A field study was carried out to determine the effect of soil application of zinc sulphate on growth, yield and quality of guava cv. L-49 during rainy and winter season. Different soil applications were applied i.e. T1 : ZnSO4 @ 0 g/plant (Control), T2 : ZnSO4 @ 50 g/plant, T3 : ZnSO4 @ 75 g/plant, T4 : ZnSO4 @ 100 g/plant, T5 : ZnSO4 @ 125 g/plant and T6 : ZnSO4 @ 150 g/plant with three replications under randomized block design. The results of the study revealed significant increase in growth, yield and quality of guava fruit. However, application of ZnSO4 @ 125 g/plant proved to be the best treatment in increasing the yield, fruit length & fruit breadth, fruit weight, TSS, Ascorbic acid and decreased acidity during rainy and winter seasons. For nutrient analysis, maximum N and Zn content in leaf and fruit was recorded under application of ZnSO4 @ 125 g/plant and maximum K content in guava fruit was observed due to application of ZnSO4 @ 100 g/plant. Thus, it can be concluded that effect of soil application of zinc sulphate increases the growth, yield and quality of guava fruits.
