Experiment on effect of foliar spray of urea and zinc sulphate with sixteen treatments combination on guava was carried out during 2012-13 at Mandsaur (M.P.). The result showed that the 2.0 % urea treatment gave significantly the maximum plant height (0.42m), fruit retention (51.92%), fruit volume (173.50ml) per fruit, minimum acidity (0.40%), TSS (11.75 0Brix) and ascorbic acid (196.87mg/100g pulp). With respect to effect of zinc sulphate the data showed maximum plant height (0.39m), fruit retention (50.56%), fruit volume (169.50 ml) per fruit, minimum acidity (0.42%), TSS (11.32 0Brix) and ascorbic acid (196.87mg/100g pulp) per plant. It was found that application of 2.0% Urea and (0.8% ZnSo4) were superior among tested different dose of both the urea and zinc sulphate under Mandsaur (M.P.) condition.
