Abstract: The experiment was aimed to determine the effect of liquid organic manures (panchagavya and vermiwash) on post harvest available soil nutrient status of bitter gourd crop. The experiment was conducted in Factorial RBD with 3 replications by foliar spraying of liquid organic manures and three varieties are used. The pooled results showed that the highest available soil nitrogen, phosphorus and potassium was recorded in the variety Peyarafuli Ucche. Whereas, among the individual number of sprays of panchagavya and vermiwash the highest available soil nitrogen, phosphorus and potassium was recorded in control i.e., water spray. In interaction effect the pooled results showed that the maximum available nitrogen, phosphorus and potash content of the soil was recorded in the treatment combination Peyarafuli Ucche and control, water spray. The highest available soil organic carbon was recorded in the treatment Gangajal-1, 3 sprays of each panchagavya 3% at 20, 40, 60 DAS and vermiwash 10% at 25, 50 and 75 DAS.
