ABSTRACT
The field experiment was carried out during rabi season of 2021-22 and 2022 at Vegetable Research Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur to find out the response of capsicum hybrids to micronutrients under protected conditions. The experiment was laid out in Split Plot Design (SPD) with 15 treatment combinations and replicated thrice. The experiment comprised three hybrids viz., Indira, Swarna and Bomby and five levels of micronutrients viz., control (no micronutrients application), soil application of Zn, Fe & B, fertigation of EDTA of Zn & Fe and solubor at 15 days interval, foliar application of vegetable special @ 5g/lit at 15 days interval and foliar application of chelated combo micronutrients @ 1g/lit at 15 days interval. Recommended package of practices for the crop were followed except treatments. Results of the experiment revealed that the hybrid Indira recorded significantly highest plant height (91.30 and 94.89 cm), number of branches (11.87 and 12.30), stem girth (4.31 and 4.60 cm), number of leaves (102.94 and 106.43), internode length (13.82 and 14.01 cm), number of flowers per plant (38.22 and 38.36), fruit set (55.10 and 55.44%), no. of fruits per plant (20.99 and 21.22), fruit weight per plant (3.69 and 3.74 kg) and fruit yield per 1000 m2 (70.36 and 71.35 q) while fruit length (11.45 and 11.71 cm), fruit diameter (10.54 and 10.66 cm), weight of placenta (18.51 and 18.71g) and average weight of fruit (193.31 and 195.90g) were significantly highest in Swarna. In case of micronutrients, foliar application of vegetable special @ 5g/at 15 day recorded significantly highest value of plant height (93.72 and 96.77cm), no. of branches (12.66 and 13.39), stem girth (4.75 and 5.12 cm), no. of leaves (105.52 and 108.68), internode length (14.75 and 15.04cm), no. of flowers per plant (41.34 and 41.95), fruit set (56.66 and 57.45%), no. fruits per plant (20.56 and 20.73), fruit length (11.85 and 12.07cm), fruit diameter (10.62 and 10.80cm), weight of placenta (18.31 and 18.46g), average fruit weight (189.03 and 191.33g), fruit weight per plant (4.12 and 4.17 kg) and fruit yield (78.64 & 79.60q/1000 m2). Hence, hybrid Indira and foliar application of vegetable special @ 5g/at 15 days may be recommended for higher productivity from capsicum crops under protected conditions.
