Abstract:
Agronomical an investigation was carried out held during the kharif season of 2022-23 at the Experimental Farm, College of Agriculture, Latur. To investigate the impact of humic acid and fertilizer on growth and yield on maize. The experiment was designed using Randomized Block Design. The eight therapies were tested three times. The treatments were T₁: Control, T₂: 100% RDF, T₃: 75% RDF +10 kg Humic acid, T₄: 75% RDF + 15 kg humic acid, T₅: 75% RDF + 20 kg humic acid, T₆: 100% RDF + 10 kg humic acid, T₇: 100% RDF + 15 kg humic acid, T₈: 100% RDF + 20 kg humic acid. Each experimental unit’s gross (total) and net plot sizes were 5.4 meter x 4.5 meter and 4.2 meter x 3.9 meter, respectively. On 4^th July, 2022, sowing was carried out using the dibbling method and a seed rate of 15 kg ha^-1. For the maize crop, recommended dose of fertilizer was 150: 75: 75: kg NPK ha^-1. The result of experimental revealed that 100% RDF + 20 kg humic acid recorded significantly highest grain yield.
