Cost effective phosphorous management practices for rainfed cotton in vertisols

摘要

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~(-1) along withsoil application of phosphobacterium (2.0 kgha~(-1)). 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 tile soil application of phosphobacterium.
