Accessing the higher production with integrated nutrient management in Custard apple cv. Arka Sahan

Abstract

The experiment evaluated different levels of recommended doses of fertilizers (RDF), farmyard manure (FYM), vermicompost, and biofertilizers like Azotobacter (AZB) and Phosphorus Solubilizing Bacteria (PSB) in custard apple cv. Arka Sahan. Treatment 75% RDF + VC @ 2 kg/plant + AZB + PSB (T₉) showed the highest plant height (400 cm), plant spread (East-West 409.96 cm, North-South 481.36 cm), number of branches (58.92), fruits per plant (31.5), and yield per plant (9.08 kg). The highest fruit weight (350.65 g) was recorded with 50% RDF + VC @ 4 kg/plant + AZB + PSB (T₁₀), while 100% RDF + 20 kg FYM (T₂) resulted in the maximum stem girth (37.49 cm). These findings underline the efficacy of integrated nutrient management in enhancing the growth and yield of custard apple cv. Arka Sahan, offering valuable insights for its cultivation under Madhya Pradesh’s conditions.
