Abstract

A field experiment was conducted at Agricultural Research Station, Kovilpatti to study the effect of different P sources on the yield of Cotton (variety.MCU.10) and on soil fertility status of rainfed vertisol. The results showed that the seed cotton yield was significantly increased by the application of FYM enriched Mussorie rock phosphate at 20 kgha" along withsoil application of phosphobacterium (2.0 kgha'). The same treatment significantly influenced the P uptake of the crop. Highest monetary return was realised. with the application of FYM enriched Mussoorie rock phosphate along with the soil application of phosphobacterium.
