The present investigation was carried out in the Agricultural Research Farm, at Horticulture Department, School of Agriculture, Jaipur (Rajasthan) during 2022-23. The experiment was laid out in Factorial Randomized Block Design which comprises of ten treatment combinations viz; Control (T0), boron @ 0.2% (T1), boron @ 0.4% (T2), zinc @ 0.2% (T3), zinc @ 0.4% (T4), Boron @ 0.2% + Zinc @ 0.2% (T5), Boron @ 0.2% + Zinc @ 0.4% (T6), Boron @ 0.4% + Zinc @ 0.2%(T7) and Boron @ 0.4% + Zinc @ 0.4% @ 0.4% (T8) and treatments were replicated three times. Appraisal of the result indicated that the influence of different concentrations of micronutrients on important parameters like vegetative growth, yield and quality attributes of chilli were significantly influenced by different concentrations of boron and zinc under local agro-climatic conditions of Jaipur (Rajasthan).
The various concentrations of boron and zinc had significant effect on various vegetative growth, yield and quality and the maximum (31.64 cm) and (49.98 cm) plant height was recorded under foliar spray of Boron @ 0.2% + Zinc @ 0.4% treatment at 45 DAT and 60 DAT, respectively, (162.47) leaves per plant, (14.54) branches per plant, (16.67) flower clusters per plant, (50.10) fruits per plant, (2.66 cm) fruit girth, minimum (45.10 days) for and (50.03 days) took for 50% flowering and first harvesting, respectively and longest (8.15 cm) fruit length, heaviest (11.79 g) fruit and highest (468.73 g) yield per plant, (11.68 kg) yield per plot, 18.03 t/ha) green chillies and (3.20 t/ha) dry red chillies yield were recorded under foliar spray of Boron @ 0.2% + Zinc @ 0.4% treatment. The foliar application of boric acid @ 0.4% performed significantly superior over control and remaining treatments to get highest green chilli yield per hectare. Results further perusal that the highest B: C ratio (3.25) from green chilli production was recorded under foliar spray of Boron @ 0.2% + Zinc @ 0.4% treatment followed by (2.95) and (2.57) B: C ratio in Boron @ 0.2% + Zinc @ 0.2% and Boron @ 0.4% + Zinc @ 0.2%, respectively. Whereas, the lowest B: C ratio (1.04) was recorded under control (T0).
