Abstract
An experiment was conducted during 2011-2012 at the Department of Fruit Science, K.N.K. College of Horticulture, Mandsaur (M.P.) on seven year old guava tree cv. L-49 with two levels of nitrogen i.e., 600 g N (100% N) and 450 g N (75% N), two levels of phosphorus i.e., 400 g P2O5 (100% P2O5) and 300 g P2O5 (75% P2O5) and a common dose of potassium i.e., 300 g K2O and 30 g each of Azospirillium and PSB inoculation and 10 kg Vermicompost. The results revealed that the age fruit weight (220.37 g), number of fruits per tree (384), TSS (11.67 0Brix), total sugar (8.06%), reducing sugar (4.17%), non-reducing sugar (3.89%), pectin (0.81%), ascorbic acid (207.90 mg/100 g pulp) and lowest acidity (0.20%) were obtained with treatment T9. The combined application of recommended dose of NPK with vermicompost (10 kg) and biofertilizers (30 g /plant) gave significantly higher fruit yield per tree (84.66 kg) with higher B: C ratio (1:5.27).
