Abstract:
An agronomic investigation was conducted during rabi 2020-21 at Experimental Farm, Department of Agronomy, College of Agriculture, Latur, to study the influence of different fertilizer levels and humic acid application on seed yield and economics of Chickpea (Cicer arietinum L.). The experimental site was clayey in texture, slightly alkaline in reaction, soil was low in available nitrogen, medium in available phosphorous and high in available potassium. Soil was well drained, with good moisture retention capacity. The experiment was laid out in Factorial Randomized Block Design (FRBD) with nine treatment combinations, consisting of two factors i.e. different fertilizer levels and humic acid application through soil, which included three levels each of different fertilizer levels and humic acid application. The different fertilizer levels were 75% RDF (F₁), 100% RDF (F₂) and 125% RDF (F₃) whereas, humic acid levels were 1 kg humic acid ha^-1 (H₁), 2 kg humic acid ha^-1 (H₂) and 3 kg humic acid ha^-1 (H₃). The gross plot size of each experimental unit was 5.4 m × 4.5 m and net plot size was 4.8 m × 3.9 m. Sowing was done on 08^th November, 2020 by dibbling method at spacing 30 cm x 10 cm. The crop was harvested on 23^rd February, 2021. The result of the experiment revealed that higher seed yield (3051 kg ha^-1),gross monetary returns(₹ 149499 ha^-1), net monetary returns (₹ 102424 ha^-1) and B:C ratio (3.18) was observed with the application of 125% RDF (F₃). Higher seed yield (3025 kg ha^-1), gross monetary returns(₹ 148225 kg ha^-1), net monetary returns (₹ 100427 kg ha^-1) and B:C ratio (3.10) was observed with the application of 3 kg ha^-1 humic acid (H₃).
