Studies on integrated nutrient management for growth and yield of custard apple

A research study titled, “Studies on integrated nutrient management for growth and yield of custard apple”. The research study was done in the field of student instruction and Custard apple Orchard, Department of Horticulture, School of Agricultural Sciences, G. H. Raisoni University Saikheda, Dist.- Pandhurna (M.P.) during Kharif 2023. The details of materials used in experimental they have 10 treatments with control, the experiment analysed under Randomized Block Design, with three replications. The treatment details are T1-100% Vermicompost as per RD, T2-100% FYM as per RD, T3-75% Vermicompost as per RD + 100 gm Azoto-bacter + 100 gm PSB + 100 gm Rhizobium, T4-75% FYM as per RD + 100 g Azotobacter + 100 g PSB + 100 g Rhizobium, T5-Per plant, 100% RDF (250:125:125 NPK) grams, T6-100 g each of Azotobacter, PSB, and Rhizobium + 75 percent RDF (188:94:94 NPK), T7-2 kg vermin-compost + 100 g each of Azoto-bacter, PSB, and Rhizobium + 75 percent RDF (188:94:94 NPK), T8-1.5kg of neem-cake + 100 gm of Azoto-bacter + 100 gm of Phosphate solubilizing bacteria + 75% RDF (188:94:94 NPK), T9-100 gm each of Rhizobium, Azotobacter, and Phosphate solubilizing bacteria + 0.75 kg of Neem-cake + 1 kg of Vermi-compost + 75% RDF (188:94:94 NPK) and T10- Control. The observation was recorded such as leaf area (cm²), fruit set (%),fruit length (cm), fruit diameter (cm), no. of fruits per plant, and total soluble solids (°B). The result revealed that the maximum leaf area (21.84 cm²), fruit set (60.58%), number of fruits per plant (10624.86 g/tree), fruit length (7.88 cm), fruit diameter (7.22 cm) and total soluble solids (22.55 °Brix) was observed under the treatments T9, while the minimum was observed under contro in all the parameters.
