Paper Title
Effect of Crop Geometry on Seed and Oil Yield in Hybrid Castor

Abstract
A field experiment was carried out during wet season (August 2016 to February 2017)at Water Management Research Block, Department of Agronomy, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai. The soil of the experimental field was sandy clay loam and experiment was laid out in Randomized Block Design (RBD), comprised of eight treatments were replicated thrice viz., G1 - 150 × 120 cm (5,555.55 plants/ha), G2 - 120 × 120 cm (6,944.44 plants/ha), G3 - 120 × 90 cm (9,259.25 plants/ha), G4 - 120 × 60 cm (13,888.88 plants/ha), G5 - 90 × 90 cm (12,345.67 plants/ha), G6 - 90 × 60 cm (18,518.51 plants/ha), G7 - 90 × 45 cm (24,691.35 plants/ha), G8 - 75 × 75 cm (17,777.77 plants/ha).Among the different spacing tried, wider spacing of 120 × 120 cm was highly influenced the yield components viz., the total number of productive spikes,total number of capsule spike-1,seed weight which finally reflected on seedand oil yield. A conducive environment under wider spacing flavours better growth and yield parameters which finally resulted in increased seed and oil yield as compared to narrow spacing of 75 × 75 cm. Keywords - Oil yield, Seed yield, Spikes, Capsules and Spacing’s.
