Effect of integrated application of chemical fertilizers, organics and biofertilizers on growth, yield and quality of guava

A field experiment was carried out during the year 2014–15 for Mrig bahar crop of guava at Horticulture Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) to studies the effect of integrated application of chemical fertilizers, organics and biofertilizers on growth and quality of winter season guava. The experiment was laid out in Randomized Block Design with three replications and ten treatments. The application of 75% RDF + Cowdung slurry 10 litre/tree + Azospirillum (100 gm/tree) + PSB 100 gm/tree (T₆), produced the highest tree height, trunk girth, tree canopy spread, diameter of shoots and number of branches. Fruit length, fruit diameter, fruit volume, pulp weight, fruit weight and fruit yield were also higher under the treatment 75% RDF + Cowdung slurry 10 litre/tree + Azospirillum (100 gm/tree) + PSB 100 gm/tree. Treatment having 75% RDF + 25% NPK/tree blended with Cowdung slurry 10 litre/tree (T₄) proved the next best treatment and lowest values for all the parameters were recorded under control.
