Abstract
The present investigation was undertaken to evaluate the “Response of Plant Growth Retardant (Mepiquat Chloride 5% AS) in Chilli cv. Pusa Jwala” at Vegetable Research Centre of G.B. Pant University of Agriculture & Technology, Pantnagar, Udham Singh Nagar (Uttarakhand) during kharif season of 2021. The experiment was laid out in Randomized Block Design with three replication and seven treatments. During the study, observation on plant height at 30, 45, 60 DAT, number of branches per plant, leaf area at, chlorophyll a, chlorophyll b and total chlorophyll content, number of fruits/plant, average fruit length, average fruit weight , yield / plant, yield per plot, and gross yield/ ha , total soluble solids, ascorbic acid content and ascorbic acid: total soluble solids ratio were recorded. The findings of present investigation revealed that the performance of chilli cv. Pusa Jwala was significantly influenced by different plant growth retardant treatments. Among all treatments, Plant Growth Retardant Mepiquat Chloride 5 % AS @ 1500 ml/ha at 15 days before initiation of flowering followed by 2nd spray at initiation of flowering (T6) was found best with respect to overall plant growth, yield and quality parameters with a total yield (59.65 q/ha). Based on overall performance, it could be concluded that under prevalent climatic conditions of Uttarakhand tarai region, plant growth retardant mepiquat chloride 5 % AS @ 1500 ml/ha at 15 days before initiation of flowering followed by 2nd spray at initiation of flowering is the best in terms of higher yield of chilli cv. Pusa Jwala. Hence, recommended for commercial cultivation, provided all other scientific management practices are followed.
