Effectiveness of Organic Control of Biodeterioration of Yam Tubers in Storage Using Plant Extract (Alstonia boonei, Xylopia aethopica, Crotolaria spp, Chromoleana odorata) Against Farmers Post Harvest Crop Loss
Journal Title: Journal of Plant Science and Research - Year 2016, Vol 3, Issue 1
Abstract
Organic leaf extracts of four plants (Alstonia boonei De Wild, Chromolaena odorata Lam, Crotolaria retusa Linn, and Xylopia aethiopica) were assessed for their effectiveness in the control of biodeterioration of yam tubers in storage. The root knot (40%) infested yam tubers were dipped in the various organic leaf plant acetone extracts for 24 hours and assessed for 6 weeks on sprout inhibition, 8 weeks for sprouting inducement and 12 weeks for biodeterioration in storage. The results indicated that there was no significant difference (P>0.05) among the treatments and control on inhibition of yam tuber sprout. However, there were significant differences (P<0.05) among the treatments as regards the inducement of sprouting. Xylopia aethiopica (43.4) and Chromolena odorata (42.4) extracts significantly (P<0.05) stimulated yam tuber sprouting potentials and also controlled yam tuber biodeterioration in storage. Chromolaena odorata (0.00) and Xylopia aethiopica (0.00) best inhibited the yam biodeterioration activities in 12 weeks of storage as there were significant differences (P<0.05) among the treatment means of Crotoleria spp, Alstonia boonei, and the control. The organic leaf extracts can evidiently be used for effective prevention of biodeterioration of yam tubers in storage, the study therefore recommend wide spread use by farmers.
