Effect of Chemicals on Defoliation, Defloration and Leaf Emergence on Sardar Guava in Rainy Season Crop

An investigation was conducted in order to observethe effect of chemicals, viz. Kl, KNO₃, urea and (NH₄)₂SO₄ on defloration, defoliation and leaf emergence on Sardar guava in rainy season crop. Maximum defloration and defoliation in the rainy season crop was caused by Kl (0.5%) followed by urea sprays. The days taken for the emergence of leaves were the highest (25 days) in the trees treated with KNO₂ 4 per cent, with the minimum of 21 days taken by trees sprayed with both the level of urea.
