ABSTRACT
Field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore under irrigated conditions to develop an improved technology package and evaluate the system of crop intensification (SCI) practices in castor. The experiment was laid out in randomized complete block design, comprised of eight treatments viz., T1-120 x 90 cm spacing + 100% NK (60 and 30 kg of N and K2O ha-1) + Hand weeding (HW) twice (30 and 60 DAS) - Control, T2-120 x 120 cm spacing + 100% NK + HW, T3-150 x 150 cm spacing + 100% NK + HW, T4 - 150 x 150 cm spacing + 125% NK + HW, T5-120 x 120 cm spacing + 100% NK + Mechanical weeding (MW) twice (30 and 60 DAS), T6-150 x 150 cm spacing + 100% NK + MW, T7 - 150 x 150 cm spacing + 125% NK + MW and T8 - 90 x 90 cm spacing + 100% NK + HW. The treatments were replicated thrice. The results revealed that the castor hybrid grown under SCI practices under square planting with wider spacing of 120 x120 cm along with 100% NK and mechanical weeding at 30 and 60 DAS produced higher castor bean yield. Higher stalk yield was observed at closer spacing of 90 x 90 cm + 100% NK + HW. Oil yield was higher under 120 x 120 cm spacing with mechanical weeding over others treatments. Higher nutrient uptake of total N, P and K was recorded under closer square geometry of 90 x 90 cm spacing with 100% NK and hand weeding.
