Intensification of Aonla (Emblica officinalis Gaertn.) Production through Integrated Nutrient Management

Abstract

The present experiment entitled “Intensification of aonla (Emblica officinalis Gaertn.) Production through integrated nutrient management was conducted at School of Agriculture Science, Vikrant University, Gwalior, Madhya Pradesh during rabi 2023-24 to rabi 2024-25.  The experiment was laid out in randomised block design  in three replication with following 9 treatments, viz., T1= Control (No nutrients), T2= 25 kg FYM + 100% RDF, T3 = 25 kg FYM + 100% RDF + Biofertilizers, T4= 10 kg Vermicompost + 100% RDF + Biofertilizers, T5= 12.5 kg FYM + 5 kg Vermicompost + 100% RDF + Biofertilizers,  T6= 25 kg FYM + 10 kg Vermicompost + 75% RDF + Biofertilizers, T7=  25 kg FYM + 10 kg Vermicompost + 50% RDF + Biofertilizers T8= 25 kg FYM + 10 kg Vermicompost + 100% RDF + Biofertilizers, T9 = 25 kg FYM + 10 kg Vermicompost + 100% RDF (No Biofertilizers). The result of the study revealed that maximum plant height (350.40cm), Canopy Spread (3.65m), Shoot Length (30.3cm), Fruits per tree (325), Average fruit weight (50.5g), Total Yield per Tree (14.3kg) and Ascorbic Acid (617.6 mg/100g), available N(306.4 kg/ha), available P (28.01 kg/ha), available K (276.3 kg/ha), microbial activity (27.8 X105) and ascorbic acid (716.6 mg/100g)was recorded in T6. While lowest soil pH and titrable acidity which is desirable was also recorded in treatment T6.
