| dc.description.abstract | The present investigations entitled “Studies on influence of foliar application of nutrients on growth, yield and quality of guava (Psidium guajava L.) cv. L-49”, was carried out on the four years old guava trees of cv. L-49, planted at a spacing of 6 m x 6 m in sandy laom soil at Experimental Orchard of Department of Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2016-17. For the purpose of recording data, thirty nine uniform plants were selected and sprayed with ZnSO4 (0.50, 0.75 and 1.00%), FeSO4 (0.2, 0.4 and 0.6%), K2SO4 (0.5, 1.0 and 1.5%) and Urea (1.0, 1.5 and 2.0%), before flowering and after fruit set stage, during rainy and winter season. Based on the overall quantitative and qualitative assessment of fruits, it can be concluded that all the parameters were significantly influenced significantly with different treatment except acidity, number of seeds and weight of 100 seeds. Maximum increment in growth parameters i.e. plant height, plant spread, stem girth and average shoot length, maximum number of flowers per branch, fruit set, number of fruits per plant, fruit weight, volume of fruits, fruit size (length and breadth) and yield per tree were recorded in the trees sprayed with ZnSO4 @1.00 per cent, along with minimum number of days taken for fruit set, fruit drop and number of days for fruit maturity. However, maximum value of ascorbic acid, total sugars and non-reducing sugars were recorded under K2SO4 @1.5 per cent, during both the seasons of investigation. TSS was recorded maximum in the fruits picked from the trees sprayed with K2SO4 @1.5 per cent, during rainy season, while with K2SO4 @1.0 per cent, during winter season. Reducing sugars was recorded maximum under K2SO4 @1.00 per cent and K2SO4 @1.5 per cent, during rainy and winter season, respectively. However, effect on acidity, number of seeds per fruit and weight of 100 seeds per fruit was non-significant in both the seasons. Maximum N content in leaf was obtained with Urea @2 per cent, P and K content were obtained with K₂SO₄ @1.5 per cent, Zn content was obtained with the spray of ZnSO₄ @1.00 per cent and Fe content was obtained with the spray of FeSO4 @0.6 per cent. | en_US |
