Abstract:
The field experiment was carried out at the Department of Agronomy, N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) during the rabi/summer seasons of 2014-15 to 2016-17.The treatment consists of two levels of organics viz FYM @10 t/ha and bio compost (Based on organic carbon content of FYM), two levels of bio fertilizers viz No bio fertilizer and Rhizobium + PSB each @ 10 ml each /kg seed as seed treatment and two levels of inorganic fertilizers viz 75% RDF and 100% RDF. The RDF was 20:50:50 N-P₂O₅-K₂O kg/ha. The experiment was laid out in a randomized block design with factorial concept with three replications. After three cuttings, the crop was left for seed production. The result of experiment revealed that plant height, green fodder yield, dry fodder yield, seed yield and green fodder equivalent yield found non significant due to different organic manures. However, numerically higher growth and yield were obtained with FYM. Same trend observed in case of NPK uptake. The maximum net returns and B:C ratio were also realized in application of bio compost. In case of bio fertilizers, plant height, green fodder, dry fodder and seed yield were not found significant but numerical higher yields were obtained with Rhizobium + PSB each @ 10 ml each /kg seedas seed treatment in pooled, while green fodder equivalent yield recorded significantly highest with Rhizobium + PSB each @ 10 ml/kg seed) in pooled. Similar results observed in case of NPK uptake. The net returns and B:C ratio were also realized higher with bio fertilizer application. In case of inorganic fertilizer, significantly the highest plant height, green fodder yield, dry fodder yield, seed yield and green fodder equivalent yield were recorded by 100% RDF during all the individual year as well as in pooled results over lower level 75% RDF. N, P₂O₅ and K₂O uptake also higher under 100% RDF. The net returns and B:C ratio were also secured higher with application of 100% RDF. Based on organic carbon content of FYM, the bio compost mean value were 7 t/ha.
