Effect of foliar application of humic acid on yield parameters and quality of chilli

Abstract

An experiment was carried out to study the “Effect of foliar application of humic acid on yield parameters and quality of chilli” during kharif 2020-21 at Research Farm, Chili and Vegetable Research Unit, Dr. PDKV, Akola. The experiment had eight treatments replicated thrice in Randomized block design. The treatments included: T1 -Absolute control, T2 - 100% RDF (100:50:50 kg N, P2O5 and K2O ha-1), T3, T4 & T5 -100% RDF +3 spray of HA @ 0.5, 1.0 and 1.5% respectively, T6, T7 & T8 -100% RDF +6 spray of HA @ 0.5, 1.0 and 1.5% respectively. Among all the treatments T8 (100% RDF + 6 spray humic acid @ 1.5%) treatment was found most effective treatment and recorded significantly maximum yield parameters and chlorophyll content of chilli. However, ascorbic acid content, capsaicin content, soil available nutrients and micro nutrients showed no significant change in response to humic acid treatment.
