Effect of Humic and Boric Acid on Chili (Capsicum annum L.) Growth, Yield and Quality under Arid Zone of Rajasthan

The field experiment was carried out during 2017-18 at the Agricultural Research Station,Mandor, Agriculture University, Jodhpur. The main aim of these experiments was to researchfindings on the vegetative growth, yield, and quality with treatment parameters of the chillicrop. The treatments included humic and boric acid, which were applied as foliar applicationswith different concentrations at 30, and 60 days after transplanting of the plant. The resultsobtained strongly indicated that all the treatments and their combinations had significantlyinfluenced the growth, yield, and quality of chilli. Among the various treatments, HA @ 40 mgL-1 + BA @ 40 mg L⁻¹ was found to be significantly superior in terms of increasing plant height,the number of leaves plant ⁻¹, leaf area plant ⁻¹, and the number of primary branches plant ⁻¹. With regard to fruit yield and quality parameters, the chilli plants sprayed with HA @ 40 mg L⁻¹ + BA @ 40 mg L ⁻¹ also recorded the highest fruit set per cent, the number of fresh fruits per plant, the length of fresh fruit, the diameter of fresh fruit, yield per plant and yield per ha.
