Study of intercropping systems castor oil and Legumes on seeds yield and yield related traits in twoo agroecological zones of Cameroon
Journal Title: International Journal of Advances in Scientific Research - Year 2018, Vol 4, Issue 4
Abstract
The experiment was conducted under field conditions at Ngaoundere and Bertoua, respectively in the Sudano-Guinean and Bimodal Forest zones in Cameroon and during the two consecutive cropping seasons of 2015 and 2016.Randomized complete block design with three replications was used and seven treatments : monocrops castor oil, soybean, cowpea and common bean; intercropping systems castor oil-soybean, castor oil-cowpea and castor oil-common bean. Plants growing and production parameters was assessed. Comparison of the performance of each farming systems was made on the basis of the Land Equivalent Ratio (LER). Results indicate that castor oil and Legumes productivity varies depending intercropping system, study zone and experimentation year. Castor oil seeds yield in intercropping with soybean, cowpea and common bean are 10.09, 13.52 and 17.88% folds greater than castor oil in monocrop. Castor oil is signicantly (p˂0.05) more productive in Soudano-Guinean zone (seeds yield : 160.97±1.93 Kg/ha) compared to Bimodal Forest zone (143.76±2.05 Kg/ha) of Cameroon and inversely for Legumes. Castor oil and Legumes productivity is better in 2015 than 2016. LER varies from 1.05 in intercropping system castor oil-soybean in 2016 to 1.33 in intercropping system castor oil-common bean in 2015. Intercropping systems castor bean-Legumes are avantageous for Cameroonian farmers. However intercropping castor oil-common bean is more effective compared to the both castor oil-soybean and castor oil/cowpea systems. The Sudano-Guinean zone of Adamaoua Cameroon is more favorable for castor oil growth while Legumes growth in Bimodal Forest of East Cameroon better. By cultivating castor oil in association with Legumes, Cameroon peasants contribute not only to fight against climate change but also to ensure food security.
