Abstract
The present investigation was conducted to Evaluate the effect of Integrated Nutrient Management (INM) on the Economic and Physical attributes of Aonla (Emblica officinalis Gaerten). The research was carried at Main Experiment Station, Horticulture, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during the year 2021. It was laid out in a randomized block design with 10 treatments, namely: T1 – Control, T2- RDF 100% (1kg.N: 0.5kg.P:1kg.K per tree), T3- FYM (10kg./tree) + RDF 100%, T4- Poultry Manure (7.5kg./tree) + RDF 100%, T5- FYM (10kg./tree) + RDF 50% + Azospirillium (10ml./tree), T6- Poultry Manure (7.5kg/tree) + RDF 50% + Azospirillium (10ml./tree), T7 -FYM (10kg./tree) + RDF 50% + PSB (10ml./tree), T8- Poultry Manure + RDF 50% + Azospirillium (10ml./tree), T9 –FYM (10kg/tree) + RDF 50% + Azospirillium (10ml./tree) + PSB (10ml./tree) and T10- Poultry Manure (7.5kg/tree) + RDF 50% + Azospirillium (10ml/tree) + PSB (10ml./tree).The experiment was replicated three times. Results showed treatment T10 outperformed the rest with maximum fruit set percent (78.56%), fruit retention (20.29%), fruit yield (102.78 kg/tree), fruit weight (41.89 g), fruit length (3.87 cm), specific gravity (1.05 g/cm3 ) and maximum gross return/ha Rs. (128264), Net return Rs. (92154) and Cost: benefit ratio was evaluated with the use of treatment combination T10. Thus, the treatment combination T10 is therefore recommended for application to Aonla trees in eastern Uttar Pradesh in order to obtain high yields with better quality fruits.
