Effect of Composted Municipal Solid Waste and Npk Fertilizer on the Growth and Yield of Maize (Zea Mays L) in Nsukka

ABSTRACT Municipalities are facing a growing problem of how to safely dispose off their wastes. Municipal solid waste (MSW) is waste from households, commercial centres, and institutions (school, offices). Composting is used to reduce huge pile of biodegradable MSW and convert it into value-added product like manure and biogas. Inorganic fertilizer such as NPK also exerts strong influence on plant growth, development and yield. Two-year experiments were conducted in the Teaching and Research...

Multi location Performance Evaluation of Exotic Hybrid Rice (oryza sativa l.) Varieties in Eastern Zone of Tanzania

ABSTRACT  Three exotic hybrid rice genotypes, HEU 022, HEU 188 and HEU 528 from China were tested to evaluate their stability and adaptability in the eastern agronomic zone of Tanzania. Three commonly grown varieties, SUPA, SARO 5 and TXD 88, were used as checks. A Randomized Complete Block Design (RCBD) experiment with three replications was carried out at four locations, ARI-Cholima, ARI-Katrin, Sokoine University of Agriculture (SUA) and Kilangali Rice Seed Farm all located in Morogoro Re...

Biology and Ecology of the Leafroller (Sylepta derogata Fabricius) on Okra (Abelmoschus esculentus (L.) Moench)

ABSTRACT Sylepta derogata, Fabricius a major insect pest, defoliates and causes enormous yield loss in Abelmoschus esculentus (L) Moench. Control of the pest with chemicals and other methods have not been successful due to scanty information on the biology and ecology of the pest. This study was conducted to assess the biology and ecology of Sylepta derogata on Abelmoschus esculentus. Abelmoschus esculentus was planted in early (March-June, 2009), mid (July-September, 2009) and late (Novembe...

Response of Soyabean (Glycine max (L.) Merill) to Integrated Weed Management in a Forest-Savannah Transition Ecosystem in Oyo State, Nigeria

ABSTRACT Weed infestation of soyabean field causes 65% yield reduction in the forestsavanna transition ecosystem of Nigeria. Single weed control method is often less effective. However, Integrated Weed Management (IWM), will ensure more effective and environment friendly control. There is little information on IWM application on soyabean field. This study was therefore aimed at investigating response of soyabean to IWM. Field study was carried out in the 2008 and 2009 planting seasons to as...
