Performance of Bio-enhancers and Nano-fertilizers on the Morphological and Yield Traits of Red Okra (Abelmoschus esculentus L.)

Horticultural crops are confined to various climate and environmental conditions that influence their whole life cycle and their activities. Providing proper amount of relevant nutrients is also a factor from them. One major vegetable crop of India is okra that is grown on large area. In this study, a field experiment conducted on red okra during summer season 2023 at Experimental Farm, Kharora, Mata Gujri College, Sri Fatehgarh Sahib, Punjab, India under Randomized Block Design and plants were treated with various treatments. The investigation found superior results from the treatment T6 (Nano Urea @0.4% + Panchagavya @3%) in which crop response best toward growth attributes like plant height (121.40 cm), number of secondary branches plant-1 (31.01), and harvest duration (41.57) while, minimum number of days were recorded days to first flowering (47.27), days to first fruiting (50.67) and days to first picking (53.13). Treatment T6 showed significant results among the yield parameters such as pod weight (9.74 g), pod yield (9.82 q ha-1), length of pod (10.44 cm), pod diameter (1.89 cm), number of pods plant-1 (18.44), biological yield (18.82 kg ha-1) and harvest index (52.63%). Moreover, plants represent best in yield that results in higher B:C ratio (2.94) and net retuns (₹ 399286.93 ha-1) respectively.
