An experiment was conducted at farmer’s field in Sivapuri village, Chidambaram taluk, Cuddalore district, Tamil Nadu, India, to study the effect of inorganic fertilizers, organic manures and biofertilizers on post-harvest soil nutrient status and economics of chilli var. K2. The treatments were imposed on a sandy clay loam soil. The field experiment was laid out in a randomized block design with three replications and eleven treatments. Among the different treatments experimented, the available nitrogen, phosphorus, exchangeable calcium in post-harvest soil and benefit cost ratio were significantly higher with the application of 75% recommended dose of fertilizers + poultry manure @ 5 t ha^-1 + biofertilizers + 2% MgSO₄. The findings also revealed that the maximum available potassium and exchangeable magnesium were registered in the treatment with application of 75% recommended dose of fertilizers + sheep manure @ 5 t ha^-1 + biofertilizers + 2% MgSO₄. Furthermore, the maximum content of available sulphur in post-harvest soil was recorded in the treatment which received 75% recommended dose of fertilizers + pressmud @ 10 t ha^-1 + biofertilizers + 2% MgSO₄.
