Influence of GA3 and NAA on capsicum production under protected structures

Abstract

The experiment was carried out in Polly house at Agriculture Farm, School of Agricultural Sciences 8#x38;#x38; Technology, RIMT University, Mandi Gobindgarh, Punjab, India to study the influence of GA3 and NAA on flowering, fruiting and yield attributes of capsicum cv. Indra under protected structures during 2020-21. Three levels each of GA3 (25, 50 and 75 ppm) and NAA (50, 100 and 150 ppm) along with a control (distilled water) were applied as foliar application after transplanting. Though, the Polly house was not fully under controlled and soil fertility ingredients were heterogeneous that is why the experiment was laid out in a randomized block design with three replications and all the required parameters were recorded and analysed statistically. Results revealed that application of GA3 @ 75 ppm resulted with minimum days to flowering (34.33), fruiting (44.33) and longer duration of fruiting (48.27 days) whereas, more number of flowers/cluster (4.73), number of fruits/plant (15.23), fruit setting (65.60%), average fruit weight (45.60 g), fruit yield/plant (0.69 kg), fruit yield/plot (6.95 kg) and fruit yield/ha (43.42 t) while,less days to fruit maturity (60.00)was reported under the application of NAA @ 100 ppm.
