Nutrient Management in Cotton-Chickpea Cropping System.

      Аннотация: The field experiment was conducted during 2006-07 and 2007-08 at the research farm of Department of Agronomy, MPKV, Rahuri, Dist. Ahmednagar (MS) to find the effect of different organic and inorganic sources alone or in combination with each other on growth attributes, yield attributes, yield, economics and nutrient uptake of hybrid cotton-chickpea cropping sequence under Western Maharashtra condition. The experiment was laid out in split plot design with three replications. The main plot comprised of seven treatments viz. T1: Gross recommended dose of fertilizer (GRDF) i.e.10 t farm yard manure (FYM) ha-1 + recommended dose of fertilizer (RDF) as 100:50:50 kg NPK ha-1, T2: 75 % RDF + 25 % recommended dose of nitrogen (RDN) through vermicompost, T3: 50 % RDF + 50% RDN through vermicompost, T4: 25 % RDF + 75 % RDN through vermicompost, T5: 100 % RDN through vermicompost, T6: fertilizer dose according to soil test crop response (STCR) equation and T7: Control were applied to hybrid cotton cv. Phule-492 during summer season and the sub plot treatments comprising of S1: Control, S2: 50 % RDF, S3: 75% RDF and S4: 100% RDF. Chickpea cv. Digvijay was used to the experiment in rabi season.
