Abstract:

Castor (Ricinus communis L.) is one of the oldest and most important non edible oil crops as main crop. This study was carried out to determine the effects of different inter- and intra-row spacings on the yield and yield components on Castor crop; was carried out at Babbur farm, ZAHRS, Hiriyur, Chitradurga, University of Agricultural and Horticultural Sciences, Shivamogga, Karnataka, during the growing season 2016 which comes under Central Dry Zone of Karnataka. Castor hybrids selected for the present study were DCH-177, DCH-519 and HCH-6. The field experiment was set up in a factorial RCBD and row spacings (90 and 120 cm) and intra-row spacing (60 cm) with two dates of sowing (June second fortnight and July second fortnight) were assigned in the plots. Number of branches, number of spikes, number of capsules spike-1 and seed yield were investigated. In general, wider inter row spacings and intra-row spacings, resulted in decreased seed yield. Significantly highest number of branches, number of spikes and number of capsules spike-1 (8.95, 6.66, 84.38, respectively) were obtained from 120 x 60 cm but significantly higher seed yield was noticed in 90 x 60 cm (1487.56 kg ha-1) and plant density while the lowest number of branches, number of spikes and number of capsules spike-1 (8.23, 5.80 and 844.38, respectively) were recorded from 90 x 60 cm plant density except seed yield significantly lowest was found in 120 x 60 cm (1311.90 kg ha-1).
