Abstract

  A field experiment consisting of nine treatments was conducted for two consecutive years from 2010 - 2011 and 2011-2012 in randomized block design with three replications at Navsari, Gujarat to study the effect of phosphorus on productivity in rabi Niger (Guizotia abyssinica L. Cass) - fodder Sorghum (Sorghum bicolor L. Moench) cropping sequence. Application of 20 kg P2O5 ha-1 through SSP with Phosphorus solubilizing Microbes (PSM) recorded significantly higher plant height, dry matter accumulation, capitula per plant and number of seeds per capitula and grain yield (628, 766 and 697 kg ha-1) by niger during both the years and remained at par with application of 10 kg P2O5 ha-1 from SSP + PSM. Similarly, application of 10 kg P2O5 ha-1 from SSP + 100 kg RP ha-1 + PSM preceding fodder sorghum recorded significantly higher green fodder yield of sorghum (368, 415 and 391q ha-1) and net realization from niger - fodder sorghum cropping system (5915 and 39,109₹ ha-1) over other treatments during both the years. Thus, it is evident that with respect to the economy in fertilizer use, a saving of 25 per cent RDF (20 kg N + 10 kg P2O5 ha-1) in fodder sorghum can be achieved under adequately fertilized niger - fodder sorghum cropping system.
