Effect of organic manures and inorganic fertilizers on maize yield, chemical composition and seed quality under maize: Chickpea cropping sequence

The field trial was carried out at College Agronomy Farm, Anand Agricultural University, Anand to study the effects of organic manures and inorganic fertilizers on yield, chemical composition and quality of seed of maize under Maize-Chickpea cropping sequence during the year 2015-17. There were total four organic manure treatments like (M1: no manure, M2: FYM 10 t/ha, M3: castor cake 1.0 t/ha and M4: vermicompost 2.5 t/ha), inorganic fertilizer (like F1:75% RDF andF2 100% RDF) and sulphur levels (S1: o kg S/ha and S2: 20 kg S/ha) with four replications and tested in Randomized Block Design (Factorial). The results indicated that the seed and straw yields were significantly influenced due to combined application of FYM 10 t/ha and 100% RDF (100-60-00 NPK kg/ha) along with 20 kg S/ha. The nutrients like N, P, K and S content and uptake; chlorophyll content and quality parameter like protein content of maize were also increased due to same set of organic and inorganic fertilizer application.
