Effect of Phosphorus Management on Quality of Maize (Zea mays L.) and Green Gram (Vigna radiata L.) under South Gujarat Condition

A field experiment was conducted at the College Farm, Navsari Agricultural University, Navsari to study the “Effect of phosphorus management on quality of rabi maize (Zea mays L.) and summer Green gram (Vigna radiata L.) under south Gujarat condition with an objective to assess the residual effect of rock phosphate (RP) and single super phosphate (SSP) along with Vascular Arbuscular Mycorrhiza (VAM) applied to rabi maize crops with four teen different phosphorus management treatment rock phosphate (RP), single super phosphate and Vascular Arbuscular Mycorrhiza (VAM) two levels I,e. 100% RDF (recommended dose of fertilize ) and 75% RDF in summer green gram. Application of 75 percent phosphorus as enriched rock phosphate along with VAM gave significantly higher grain yield, straw yield protein content and protein yield over rest of the treatments under study during the individual years as well as in the pool. The same trend was observed in Green gram seed and stover, from the results, it can be concluded that the application 75 percent rock phosphate along with VAM to rabi maize and improvements in quality of both crops of sequence.
