Effect of Leaf Powder Treatment on Root-Knot Nematode (Meloidogyne incognita) and Proximate Composition of Yam Tubers; Implication on Food Security
Journal Title: Journal of Plant Science and Research - Year 2016, Vol 3, Issue 1
Abstract
Farmers face several challenges in yam production occasioned by incidents of pest and pathogens among which are nematodes, termites, beetles. The effect of leaf powder of five plants, Ocimum basilicum L. (Basil plant), Vernonia amygdalina.L., (bitter leaf) Azadirachta indica L. (neem) Moringa oleifera Lam. (horseradish) and Piper nigrum Schum and Thonn (bush pepper), were assessed for their effect on root-knot nematode, Meloidogyne incognita in yam and their influence on tuber proximate composition. The trial was conducted in Abia State, Nigeria laid out in completely randomized design, replicated three times. Data were collected and analyzed using descriptive statistics and analysis of variance (ANOVA). Results indicate that carbohydrate content increased by 10.4% in Basil plant, 21.4% in Bitter leaf, 8.1% in Neem, 11.1% in horseradish and 12.8% in Bush pepper treated yam tubers at 0.01t/ha when compared to the control. The protein composition increase was not significant (P > 0.05). Application of leaf powder at 0.01t/ha before planting and during tuber initiation suppressed root knot nematode population and consequently, improved growth and yield of yam, improved the dietary value of the yam tubers which has the potentials for enhanced nutrition and food security of the Nigerian citizens and it is therefore recommended for wide spread farmers’ awareness and adoption.
