Abstract
In the current investigation, each of five castor (Ricinus communis L.) hybrids (DCH-4, DCH-117, DCH-177, DCH-519 and GCH-4) and varieties (DCS- 9, 48-1, JC-12, local green and local pink) raised under irrigated condition showed significant variation with regard to growth and yield attributes. Among the castor hybrids/varieties, DCH-519 hybrid showed significantly superior plant height, number of branches/plant, number of leaves /plant, leaf area, leaf area index, leaf area duration, leaf yield and seed yield followed by DCS-9 variety, GCH-4 hybrid, DCH-177 hybrid and 48-1 variety. However, local green and local pink castor varieties had inferior values for all these attributes.
