(Unpublished).https://krishikosh.egranth.ac.in/handle/1/5810205900A field study entitled “Yield and quality of chilli as influenced by foliar spray of humic acid in Inceptisols” was conducted during kharif 2021-22 at Research Farm, Chilli & Vegetable Research Unit, Dr. PDKV, Akola. The experiment had eight treatments replicated thrice using randomized block design. The treatments included, Absolute control, the humic acid sprays at 0.5, 1.0 and 1.5% were applied as 3 sprays and 6 sprays respectively along with 100% RDF at various growth stages. The data revealed that the significantly highest green chilli yield (270.10 q ha-1) was recorded with the application of 100% RDF + 6 sprays of humic acid @ 1.5% (T8). There were increment of 8.92% increase over RDF, which was at par with the treatment of application of 6 sprays of HA @ 1% (T7). All the growth parameters like fruit weight, fruit length and fruit width were recorded highest in the treatment T8. The nutrient uptake of N (24.06 kg ha-1), P (9.49 kg ha-1), K (26.81 kg ha-1) and S (8.72 kg ha-1) was recorded highest in the treatment 100% RDF + 6 sprays of humic acid @ 1.5% concentration (T8). The quality parameters such as Chlorophyll (55.35), Flavonoid (1.21) and Total Soluble Solids (13.22 ° Brix) was recorded significantly highest in treatment T8. Whereas the highest Anthocyanin content (0.14) was recorded in absolute control T1. However, the Nitrogen Balance Index (48.98) was reported highest in treatment (T6). The data showed that there were no significant differences in ascorbic acid (140.67 mg 100g-1), capsaicin (1.24%) and uptake of micronutrients by chilli plant, fruit and soil nutrient status after harvest of crop. It can be concluded that the foliar application of 6 sprays of humic acid @ 1.5% along with 100% RDF significantly resulted on growth and yield of chilli under the climatic conditions of Akola.EnglishThesis
