Item Leaf area manipulation and Nitrogen Fertilization on yield and Agronomic traits of maize(1978) Remison, S.U.; National Cereals Research Institute, IbadanThe grain yield of maize is severely reduced by leaf diseases and pest’s which are fairly abundant in tropical environments because of the favourable weather conditions. The most common leaf diseases of maize in Nigeria are maize rust caused by Puccinia polysora leaf blight caused by Helminthosporium maydis leaf spot caused by Curvularia pallescens maize streak virus (MSV) transmitted by insect vectors of the genus Cicadulina and brown spot caused by Physoderma maydis (Fajemisin, 1978). Yield losses in the humid rain forest zone especially to rust, as high as 44 percent have been recorded (Craig, 1966).Item Progress from Half-Sib Selection in Kitale Station Maize(1973) Eberhart, S.A.; Harrison, M.N.; A.R.S. U.S.D.A., Iowa State University, Ames, Iowa, U.S.A. International Institute of Tropical Agriculture, P.M.B. 3520, Ibadan, Nigeria.A strain of Kenya flat-white maize (Zea mays L.) had been maintained on the Agricultural Research Station at Kitale, Kenya for several years by visual selection of the ears at harvest (mass selection) to provide seed the following year. Since the Kenya flat-white complex apparently traces back to varieties from South Africa that originally came from the southern U.S.A such as "Hickory King", "White Horse tooth", "White Pearl", and others [6], the late maturity and disease resistance of the Kenya strain suggests that mass selection has been effective in developing adapted varieties for Kenya conditions.
