Abstract:
A field experiment was conducted at farmer’s field in Varagurpettai village of Chidambaram taluk, Cuddalore district to study the effect of utilization of bone sludge, by-product of ossein industry as manure on the yield and economics of sugarcane during February 2021 – February 2022. The results of the present study revealed that the yield of sugarcane was favourably influenced by the use of bone sludge compost. Application of bone sludge compost at the rate of 5 t ha^-1 + pressmud compost @ 5 t ha^-1 + balance N and K through fertilizers recorded the highest cane yield of 185.12 kg ha^-1 and registered a maximum return rupee^-1 invested value of 4.15. Considering the results of the present investigation it can be concluded that application of bone sludge compost @ 5 t ha^-1 + Pressmud compost @ 5 t ha^-1 + balance N and K through fertilizers registered the highest yield and return rupee^-1 invested value in sugarcane.
