Effect of Integrated Nutrient Management on Productivity and Quality of Aonla

Abstract

The field experiment was conducted at the Horticulture Research CRC Farm – 1 of the Department of Horticulture, School of Agriculture, ITM University Gwalior (M.P. during the year 2019 and 2020 to study the effect of Integrated Nutrient Management on fruit yield and quality of aonl. The experiment was laid out in the randomized block design with three replications and eleven treatments viz. (control - RDF (1000: 500:1000 g/ tree, 3/4thof RDF + FYM, 3/4thof RDF + FYM + Azotobacter (100g, 3/4thof RDF + FYM+ Azospirillum (100g, 3/4thof RDF + FYM+ PSB (100g, 3/4thof RDF + FYM+ Azotobacter + Azospirillum + PSB(100g/tree each, ½ of RDF + FYM, 1/2 of RDF + FYM+ Azotobacter (100g, 1/2 of RDF + FYM + Azospirillum(100g, ½ of RDF + FYM + PSB(100g, ½ of RDF + FYM + Azotobacter + Azospirillum + PSB (100g/tree, each. The results revealed that among different treatments, application of ½ of RDF + FYM + Azotobacter + Azospirillum + PSB recorded higher fruit yield, TSS, Total sugar, Ascorbic acid which was followed by application of ¾th of RDF+ FYM + Azotobacter + Azospirillum + PSB except acidity. Thus, application of ½ of RDF + FYM + Azotobacter + Azospirillum + PSB was found to best for improving the soil nutrient status which will in turn help in improving the yield of Aonla.
