An experiment was carried out during the Kharif season of 1986 to 1995 on light textured soils of North Saurashtra Agro-climatic Zone at Jamkhabhalia to study the nitrogen and phosphorus requirement of castor (Ricinus communis L.) under rainfed conditions. The results revealed that significantly higher grain yield (617 kg/ha), highest net ICBR (1:3.59) and FUE (2.8) were obtained when castor was fertilized with 30 kg N/ha. Application of phosphorus @ 30 kg P2O5/ha significantly increased yield of castor with net ICBR 1:1.10 and 1.83 FUE as compared to control.

Abstract


An experiment was carried out during the Kharif season of 1986 to 1995 on light textured soils of North Saurashtra Agro-climatic Zone at Jamkhabhalia to study the nitrogen and phosphorus requirement of castor (Ricinus communis L.) under rainfed conditions. The results revealed that significantly higher grain yield (617 kg/ha), highest net ICBR (1:3.59) and FUE (2.8) were obtained when castor was fertilized with 30 kg N/ha. Application of phosphorus @ 30 kg P2O5/ha significantly increased yield of castor with net ICBR 1:1.10 and 1.83 FUE as compared to control.
