Effect of planting ratio (Female: Male) and foliar spray of plant growth regulators on seed yield in CMS based chilli hybrid UARChH42 (JCH42)

Present experiment was aimed to determine the effect of planting ratio followed by PGR spray on seed yield of newly released chilli hybrid UARChH42 (JCH42). Significantly higher value of number of fruits plant⁻¹ (37.86 and 44.01), seed yield (27.68 and 27.75 kg ha⁻¹) and number of seeds per fruit (72.68 and 74.30) was obtained in P₂ (2:1) planting ratio and PGR spray of S₄ (NAA @ 40 ppm) respectively. Similar trend was seen in treatment combination P₂S₄ (2:1 + NAA @ 40 ppm). Results revealed that 2:1 ratio proved to be best for natural crossing followed by spraying at flower initiation stage with NAA @ 40 ppm to obtain higher seed yield.
