Effect of integrated nutrient management practices on growth, productivity and profitability of aonla

Abstract

The experiment was conducted with an aim to evaluate the effect of integrated nutrient management on vegetative growth, yield and profitability of aonla cv. NA-7 at the Instructional cum Research Fruit Orchard, K.N.K. College of Horticulture, Mandsaur (M.P.), Department of Fruit Science, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.) during 2014-15. Randomized block design (RBD) having three replications was applied in the experiment. Eight years old uniform trees of Aonla (Emblica officinalis Gaerth) cv. NA-7 (Narendra Aonla-7) were selected for this study. There were eleven treatment combinations (Control, 800:400:800 g NPK per plant, 400:200:400 g NPK + 10 kg FYM per plant, 400:200:400 g NPK + 10 kg Vermicompost per plant, 800:200:400 g NPK + 50 g PSB per plant, 600:400:800 g NPK + 40 g Azotobactor per plant, 600:200:800 g NPK + 50 g PSB + 40 g Azotobactor per plant, 400:0:400 g NPK + 10 kg FYM + 50 g PSB per plant, 400:0:400 g NPK + 10 kg Vermicompost + 50 g PSB per plant, 200:0:400 g NPK + 10 kg FYM + 50 g PSB + 40 g Azotobactor per plant and 200:0:400 g NPK + 10 kg Vermicompost + 50 g PSB + 40 g Azotobactor per plant). The results of present experiment shows that the treatment combination 600:200:800 g NPK + 50 g PSB + 40 g Azotobacter per plant has been found most appropriate integrated nutrient dose under agro-climatic conditions of Malwa plateau for obtaining maximum vegetative growth and yield (67.68 kg/tree) for improving the reproductive parameters and it also gave maximum net income (Rs. 73174.14). The next best treatment combination were 600:400:800 g NPK + 40 g Azotobacter per plant, 800:200:400 g NPK + 50 g PSB per plant and 200:0:400 g NPK + 10 Kg Vermicompost + 40 g Azotobacter per plant in descending order.
