Field experiments were conducted at Tapioca and Castor Research Station, Experimental farm during Rabi 2015 and Kharif 2016 season under irrigated and rainfed condition, respectively to find out the optimum plant density for higher productivity and economics of hybrid castor DCH 519. The experiment consisted of six treatments such as T1 120x120 cm, T2 150x120 cm, T3 150x150cm, T4 180x120 cm, T5 180x150 cm, T6180x180 cm. The experiment was conducted in Randomized Block design with four replications. The results of the experiment indicated that wider spacing of 180 x 180 significantly had the highest yield attributing characters such as No. of effective spikes plant-1, primary spike length, No. of capsules spike-1 which was observed to be on par with 180x150cm while significantly higher plant height and seed yield were recorded under closer spacing of 120x120cm which was followed by 150x120cm spacing. Higher gross return of Rs. 51696/ha and net return of Rs.29596/ha with BCR of 2.33 was realized under closer spacing of 120x120cm.
