Two field experiments were conducted during the 1993 and 1994 growing seasons at Samaru (7° 38' E; 11° 11' N), northern Nigeria, to evaluate N-use efficiency (kg grain per kg available soil N) and yield of 5 maize genotypes planted early in the season under five levels of N. The hybrid (8644-27) ...
The type and level of disease reaction of Ugandan maize genotypes to Peronosclerospora sorghi was characterized using several variables during the second season of 1994 at two locations, Nazaretti in Mpigi district and Ikulwe in Iganga district. Maize genotypes differed significantly (p 0.05) in ...
Biotic constraints (insects, diseases, parasitic weeds) and abiotic stresses (drought) are widespread and pose a constant threat to maize production worldwide. Tropical environments provide the greatest opportunity for evolution of insects and diseases because of the favourable year- round climat...
A parasitic weed, Striga hermonthica (Del.) Benth., infects millions of hectares of arable land in sub-Saharan Africa, and it threatens production of cereal crops. The objectives of this study were to investigate inheritance in maize (Zea mays L.) inbred lines of tolerance and resistance to S. he...
Maize fiber was evaluated in wet, dry and silage form with 200 g cotton cake supplementation in growing Nellore Brown ram lambs (24.8±0.96) using six sheep per treatment in a growth-cummetabolism trial of 90 days with collection of feed, leftover, feces and urine samples during the last ten days....
On-farm trials were conducted at Kaduna in the northern Guinea savanna of Nigeria in 1996 and 1997. The objective was to investigate the residual effects of Mucuna and cowpea grown during the first 2-3months of the season on subsequent maize yields, to elicit farmers' feedback on these cropping s...
Considerable progress has been made in breeding improved cowpea varieties in the last five years. The major breeding objectives were to develop high yielding cowpea varieties for sole cropping as well as intercropping with acceptable seed types and resistance to major diseases, insect pests, nema...
