Integrated nutrient management in ber (Zizyphus mauritiana Lamk.) cv. Gola under Malwa Plateau conditions of Madhya Pradesh

Abstract

Not AvailaA field experiment was carried out with different treatment combinations of organic manures (FYM @ 53, 39.75 and 26.5 kg, vermicompost @ 26.5, 19.86 and 13.25 kg), inorganic fertilizers (full dose of recommended fertilizer, 50% dose of recommended fertilizer and 25% dose of recommended fertilizer) and bio-fertilizers (Azotobacter and PSB) on five-year-old ber trees cv. Gola under Malwa plateau conditions. The results revealed that the application of 50% recommended dose of fertilizer through vermicompost + 50% RDF through NPK + 50 g Azotobacter + 50 g PSB (T7) significantly increased the plant height (2.43 m), canopy volume (9.56), number of primary (16.93) and secondary branches (24.92) per shoot, fruit set (7.30%) and fruit retention (40.95%), fruit length (3.58 cm) and diameter (3.31 cm), fruit volume (22.25 ml), pulp weight (20.06 g), stone weight (1.91 g), average fruit weight (21.97 g), yield (34.14 kg/tree), TSS (20.85°Brix), ascorbic acid (74.04 mg/100 g pulp), reducing sugar (5.15%), non-reducing sugars (4.74%), total sugars (9.89%), TSS/acid ratio (160.38) and chlorophyll content in leaves spad value (71.00).
