Abstract: Castor (Ricinus communis L.) is one of the oldest cultivated crops, but currently it represents only 0.15% of the vegetable oil produced in the world. Castor oil is continuing importance to the global speciality of chemical industry because it is the only commercial source of a hydroxylated fatty acid. An experiment was carried out during August 2016 to February 2017 at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai, to study the effect of crop geometry on physiological characters and yield of hybrid castor (YRCH 1). The soil of the experimental field was sandy clay loam and experiment was laid out in Randomized Block Design (RBD) with comprised of eight treatments were replicated thrice viz., G1 - 150 × 120 cm (5,555 plants ha-1), G2 - 120 × 120 cm (6,944 plants ha-1), G3 - 120 × 90 cm (9,259 plants ha-1), G4 - 120 × 60 cm (13,888 plants ha-1), G5 - 90 × 90 cm (12,345 plants ha-1), G6 - 90 × 60 cm (18,518 plants ha-1), G7 - 90 × 45 cm (24,691 plants ha-1) and G8 - 75 × 75 cm (17,777 plants ha-1). Among the different crop geometry, 120× 120 cm spacing registered higher dry matter production (DMP) and Leaf area index (LAI), the spacing of 150 × 120 cm recorded higher crop growth rate, total chlorophyll content, relative leaf water content. Significantly seed and oil content was registered in wider spacing (120× 120 cm), which provides a favorable environment to each and every plant parts as compared to narrow crop geometry of 75 × 75 cm.
