Abstract:

The experiment was carried out on Kinnow mandarin (Citrus reticulata Blanco.)” to see the “Effect of foliar spray of plant growth regulators and micro nutrients. The experiment was laid out in Randomized Block Design (RBD) having 15 treatments with three replications each. Foliar application of plant growth regulators and micro nutrients viz. NAA (20 & 40 ppm), 2,4-D (10 & 20 ppm), Zinc sulphate (0.5 %), Borax (0.5 %) alone and in combinations were applied twice in the month of April and May on 14 years old Kinnow trees. The fruit growth characters like fruit weight, length, breadth, volume of fruit and fruit retention were recorded at monthly intervals and maximum fruit growth was observed with treatment 20ppm NAA+ ZnSO4 0.5% followed by 2,4-D 10 ppm +0.5% ZnSO4. The per cent fruit drop was minimum in 10 ppm 2,4-D treatment. However, maximum dropping of fruits were observed under control (6.44%) recorded at final stage of study. The number of days taken for fruit maturity was higher in control (179.33) than other treatments while it was minimum under 2,4-D 20 ppm (170.12) followed by NAA 20 ppm + Borax 0.5%.
