Effect of preharvest spray of NAA, GA₃ and Urea on fruiting, fruit quality and yield of ber (Zizyphus mauritiana Lamk.) cv. Banarasi Karaka

An experiment was conducted to assess the effect of preharvest sprays of NAA, GA₃ and Urea on fruiting, fruit quality and yield of ber cv. Banarsi Karaka at the Horticulture Garden, Department of Horticulture, C.S. Azad, University of Agriculture and Technology, Kanpur during 200S-09. The experiment was planned in a randomized block design with nine treatments replicated thrice, viz. T₁ (control), T₂ (NAA 15 ppm), T₃ (NAA 25 ppm), T₄ (GA₃ 20 ppm), T₅ (GA₃ 30 ppm), Ts(Urea 1.5%), T₇ (Urea 2.0%), T₈ (T₂ +T₄ +T₆) and T₉ (13 +T₅ +T₇). Foliar sprays of 25 and 30 ppm NAA and GA₃ in conjunction with 2% urea produced significantly bigger sized fruits measuring 3.93 cm in length and 2.85 cm in width with maximum TSS (16.60° B) and sugar content (11.20%) as against the minimum of 2.00 cm, 3.00 cm, 13.8°B and 8.52% values, respectively recorded under control. The maximum fruit yield amounted to 147.00 kgltree in comparison to 55.0 kg of control.
