Abstract
The present investigation was conducted to evaluate influence of nutrient management using bio-organic manure on bio-chemicals in Aonla. 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 thrice. Results showed treatment T10- Poultry Manure (7.5kg/tree) + RDF 50% + Azospirillium (10ml/tree) + PSB (10ml./tree) outperformed the rest with maximum TSS (11.830 Brix), Ascorbic acid content ( 599.98 mg/ 100g fruit pulp), reducing sugar (3.28%), non-reducing sugar (3.00%), total sugar (6.29%) and minimum acidity (1.32%). The treatment combination is therefore recommended for application to Aonla trees in Eastern Uttar Pradesh in order to obtain high yields with better quality fruits.
