Effect of Integrated Nutrient Management on Fruit Yield and Quality of Peach (Prunus persica L. Batsch) cv. July Elberta

Abstract

The present studies were carried out in Experimental Block, Department of Fruit Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the year 2015-16. Nine years old trees of uniform size and vigour planted at 4.0 x 2.0 m spacing were selected for the studies. The experiment was laid out in a randomized block design with 11 treatments. The maximum increased in fruit set (87.70%) and yield (20.16 kg/tree) were observed significantly higher under 75% RDF + vermicompost 15 kg/tree. Maximum fruit length (64.06 mm), breadth (61.89 mm), fruit weight (129.51 g), total soluble solids (13.33 ºB) and total sugars (7.51%) were recorded under 75% RDF + vermicompost 15 kg/tree, however, highest fruit firmness (6.56 kg/cm2) and lowest titratable acidity (0.50%) were found with 4 applications of jeevamrut.
