Abstract A pot experiment was conducted at S. K. N. College of Agriculture, Jobner during rabi using cowpea as a test crop to study the response of cowpea to organic manures and soil salinity. The seed yield of cowpea increased to the extent of 13.5 and 27.3, and 24.9 and 32.3 and stover yield to the extent of 8.6 and 13.2, and 12.4 and 19.9% with the application of 5 and 10 t FYM/ha and 2.5 and 5 t vermicompost/ha, respectively, over control. The increasing level of organic manures increased the N, P, K Ca and Mg content of seed and stover and OC of soil, while decreased Na content of seed and stover, bulk density, ECe, pH and ESP of the soil. The P, K, Ca and Mg content of seed and straw and OC pH and ESP decreased with increasing level of EC, while N and Na content of seed and stover, bulk density and ECe of soil increased with increasing level of EC of soil.
