The present investigation was conducted during the kharif seasons of 2024 and 2025 under a naturally ventilated polyhouse at the Vegetable Research Farm, CSKHPKV, Palampur, to evaluate the influence of plant growth regulators on capsicum productivity and economics. The experiment was laid out in a Randomised Block Design with three replications, comprising 13 treatments involving foliar application of GA₃ and NAA at 50 and 75 ppm during different crop growth stages. The results revealed that NAA @ 75 ppm applied as four sprays at vegetative stage, flower initiation, and 30 and 60 days after flower initiation significantly improved pericarp thickness (5.94 mm), total soluble solids (6.9˚B), ascorbic acid content (126.17 mg/100g) and titratable acidity (0.206%) whereas, GA₃ applied @ 75 ppm with four sprays at the same stages recorded highest yield (22.81 q/250m2) and its attributes, making it the most economically rewarding treatment for commercial cultivation of capsicum variety ‘Indra’ under naturally ventilated polyhouse conditions of mid hills of Himachal Pradesh.
Plant growth regulators (PGRs) offer a potential means of improving chilli productivity by regulating vegetative growth, flowering, fruit development, and biochemical quality. This study evaluated the responses of Kulai chilli (Capsicum annuum L.) to foliar applications of naphthaleneacetic acid (NAA; 20 and 40 mg L⁻¹)...

The overuse of synthetic growth regulators in chilli (Capsicum annuum L.) cultivation has compelled farmers to seek eco-friendly alternatives. The present study evaluated the effects of three organic bio stimulants, namely sea-weed extract, krishi tee and vermiwash on growth, yield and quality of chilli under open fiel...
Dragon fruit (Hylocereus costaricensis) is an emerging fruit crop in subtropical regions, where optimization of vegetative growth and fruit development is essential for improving productivity. A two-year field experiment was conducted during 2024-25 and 2025-26 under subtropical conditions of Western Uttar Pradesh, Ind...
