Abstract

A field experiment was conducted at university guava orchard, Rajmata Vijayaraje Scindia Krishi Vishwavidyalaya, Gwalior (M.P.) during the year 2014-15.Guava plants were treated with zinc sulphate at 0.2 per cent, 0.3 per cent and 0.4 per cent and GA 3 at 30 ppm, 60 ppm and 90 ppm along with a control.Higher concentration of zinc sulphate (0.40%) and GA 3 (90 ppm) spray enhanced the tertiary shoot length (8.08 cm), Shoot diameter (4.26 mm) and number of leaves per shoot (7.10).The maximum fruit set (95.55%) and fruit retention (77.48%) was recorded with higher dose of zinc sulphate and GA 3 .The higher dose of zinc sulphate and GA 3 minimize the fruit drop (18.07%).Maximum TSS (11.65) was recorded in higher dose of zinc sulphate and GA 3 .Minimum acidity (0.20%) was recorded in higher dose.
