Impact of foliar nutrition on growth, yield attributes, yield, quality parameters and economics of groundnut [Arachis hypogaea (L.)] under rainfed condition

An investigation was carried out at College Farm, College of Agriculture, Navsari Agricultural University, Bharuch during the kharif season of 2023 to study the “FOLIAR NUTRITION IN GROUNDNUT [Arachis hypogaea (L.)] UNDER RAINFED CONDITION”. The experiment was laid out in a randomized block design with nine treatments, which included: T1 (Control), T2 RDF (12.5-25-00 NPK kg/ha), T3 (RDF + 2% Panchagavya), T4 (RDF + 2% Cow urine), T5 (RDF + 2% Vermi bed wash), T6 (RDF + 1% Novel), T7 (RDF + 2% Urea), T8 (RDF + 1% 19-19-19) and T9 (RDF + Nano urea 2 ml/lit), each with three replications. Foliar nutrition apllied at flowering and pegging stages of groundnut. The soil of experimental plot was clayey with low in available nitrogen (237 kg/ha), available phosphorus (34 kg/ha) and high in available potash (325 kg/ha). The soil reaction (pH) was slightly alkaline (7.78). The finding revealed that, significantly higher all the growth parameters viz. plant height at 75 DAS (41.56 cm) and at harvest (63.95 cm), number of branches per plant at 75 DAS (8.692) and at harvest (10.00), dry matter accumulation per plant at harvest (40.44 g) recorded Yield attributes viz. number of pods per plant (18.43) and number of seeds per pod (2.563) as well as seed yield (1384 kg/ha), haulm yield (2620 kg/ha) and shell percentage (72.16%) recorded significantly the highest with T3 (RDF + 2% Panchagavya) which was statistically at par with T8 (RDF + 1% 19-19-19) and T6 (RDF + 1% Novel).
