Abstract: A field experiment was conducted to assess the effect of potash management through gliricidia green leaf manuring on soil fertility and yield of soybean in Vertisols at Research field of AICRP for Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra during kharif 2018. The experiment comprised of six treatments and four replications laid out in Randomized Block Design. The results indicated that application of 75% N +100% P+15 kg K (inorganic) +15 kg K through gliricidia resulted in improvement in soil fertility with higher soybean yield and was on par with application of 75% N +100% P +30kg K through gliricidia, application of 50% N +100% P+30kg K through gliricidia and application of 100% RDF (30:75:30 NPK kg ha^-1). Hence, it is concluded that the integrated application of 75% N +100% P+ 50% K through chemical fertilizer and 50% K through gliricidia green leaf manuring at 30 DAS resulted in improvement in soil fertility and yield of soybean grown in Vertisols.
