Abstract: The experiment was carried out in the field of AICRP on tuber crops, Research and Instructional Farm, Department of Horticulture, College of Agriculture (IGKV), Raipur (C.G.) during Kharif, 2010-11. The experiment was laid out in a randomized block design with nine treatments three replicationswith an objective to study the effect of intercropping cowpea, french bean, turmeric and ginger with colocasia under agro-climatic conditions of Chhattisgarh plains. The treatment consisted of sole and intercropping viz: TI- Colocasia (sole) with 60 x45 cm, T2 – Colocasia + Cowpea (1:1) with 60 : 30 cm, T3 – Colocasia + Cowpea (1:2) with 60 : (15 : 15) cm, T4 – Colocasia + French bean (1:1) with 60 : 30 cm, T5 – Colocasia + French bean (1:2) with 60 : (15 : 15) cm, T6– Colocasia + Turmeric (1:1) with 60 : 30 cm, T7 – Colocasia + Turmeric (1:2) with60 : (15 : 15) cm, T8 – Colocasia + Ginger (1:1) with60 : 30 cm, T9 – Colocasia + Ginger (1:2) with60 : (15 : 15) cm.The name of variety for different crops areColocasia : Indira Arvi-1, Cowpea : Pusa komal, French bean : Contender,Turmeric : Rashmi, and Ginger: SuprabhaThe result revealed that growth parameters of colocasia viz., plant height, number of leaves and yield attributes like number of cormels plant-1, weight of cormels plant-1 weight of mother corm plant-1, total yield plant-1, total tuber yield and marketable tuber yield t ha-1 were recorded significantly highest under sole cropping of colocasia.Among all intercropping system, plant height and number of cormels plant-1were observed higher under colocasia + cowpea at the 1:1 row ratio followed by colocasia + french bean at the 1:1 row ratio. Beside that; weight of cormels plant -1, weight of mother corm plant-1, total tuber yield and marketable tuber yield t ha-1 were found higher under colocasia + ginger at the 1:1 row ratio among the other intercropping system.
