Abstract:
A field study was conducted during kharif 2019-20 at Research field of AICRP for Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra to assess the effect of potash management through gliricidia green leaf manuring on soil fertility and yield of rainfed cotton in Vertisols. The soil of the experimental site was Vertisol which was moderately alkaline in reaction, low in available nitrogen, medium in available phosphorus and high in available potassium. The nine treatments replicated three times in randomized block design comprised of control, 100% RDF (60:30:30 NPK kg ha-1), 100%, 75% and 50% N and 100% P through chemical fertilizers and the combinations of 15, 20 and 30 kg K ha-1 through gliricidia green leaf manure at 30 DAS and remaining recommended dose of potassium as basal dose through inorganic fertilizers. The results indicated that application of 100% NP + 10 kg K (inorganic) + 20 kg K ha-1 through gliricidia green leaf manure at 30 DAS recorded significantly higher cotton yield with improvement in soil fertility and it was found to be on par with application of 100% NP + 15 kg K (inorganic) + 15 kg K ha-1 through gliricidia green leaf manure. Hence, it is concluded that conjunctive application of 100% NP + 10 kg K (inorganic) + 20 kg K ha-1 through gliricidia green leaf manuring at 30 DAS resulted in improvement in soil fertility and yield of cotton grown in Vertisols under rainfed conditions.
