Abstract
The investigation on âEffect of integrated nutrient management for evaluating the quality parameters of manila tamarind (Pithecellobium dulce) cv. Localâ was carried out to identify the application of optimum concentration of nutrients (NPK @ 100% and 50%) along with biofertilizers (FYM, vermicompost and phosphobacteria) to evaluate the quality parameters viz., TSS (°Brix), reducing sugar, dietary fibre, titrable acidity, total chlorophyll content, relative water content, ash (g 100-1 fresh weight), tanin (mg 100-1 fresh weight), moisture content (%), total phenols (mg 100-1 fresh weight), ascorbic acid (mg 100-1 fresh weight), total flavanoids (mg 100-1 fresh weight) of manila tamarind. The field experiment was laid out in randomized block design in three replications with ten treatments. On evaluating the quality parameters 50% of NPK + 5 kg vermicompost + 10 kg FYM+ phosphobacteria 100 g(T8 ) shows better significant results than control. The present study concludes that the application of 50% of NPK along with 5 kg vermicompost, 10 kg FYM and phosphobacteria 100 g can be recommended for the optimum dose for application of integrated nutrients to improve the quality of manila tamarind.
