Abstract
The present investigation entitled “studies on effect of different growth promoting substances on flowering, fruiting, yield and quality attributes of Ber (Ziziphus mauritiana Lamk.)” was conducted at Dry Land Horticultural farm Suragi, Pt. Shiv Kumar Sashtry College of Agriculture and Research Station, Rajnandgaon, IGKV, Raipur (C.G.) during the year 2019-20. This experiment was conducted to assess the influence of foliar application of different growth promoters on flowering , fruit set , fruit retention, fruit drop, yield and quality parameter of ber (Ziziphus mauritiana Lamk.) cv. Apple Ber. Total 16 Treatments viz. Urea (1, 2, 3%), GA3 (10,
25, 40 ppm), NAA (10, 30, 50 ppm), 2-4, D (5, 10, 15 ppm), Humic acid (1, 1.5, 2%) with 3
replication were applied in RBD design. The result revealed that maximum initial fruit set (3711), fruit retention (24.92%) and minimum fruit drop (75.07%) were recorded with NAA 50 ppm. Highest fruit yield (37.62kg/ Plant) produced with 40ppm GA3 over control (18.35 kg/Plant). The quantitative character of fruits i.e. maximum volume (49.57cc), length (4.78cm), diameter (4.74mm), fruit weight (50.99g), pulp weight (46.45g) found with 40ppm GA3. The minimum stone weight (2.75g) observed with Urea @ 1%. The maximum peel thickness obtained with humic acid 2%. The qualitative character i.e. TSS (12.9 0Brix), ascorbic acid (87.46mg/100g), reducing sugar (4.82 %), non- reducing sugar(7.313 %), Total sugar (12.13%) observed maximum and minimum acidity (0.43%) with the application of GA3 @ 40ppm.
