Investigations based on field records and experiences at the Guinea Fowl Production Research Unit of the Kainji Lake Research Institute have shown that some diseases management conditions which include: yolksac, fungal infections, collibacillosis, helminthiasis, management problems in particular inbreeding, moulting, heatstroke and nutritional deficiencies affect significantly the reproductive organs, egg laying and hatchability.

Both the initial, and long term symptom responses to single and mixed infections with potato x potexvirus (PVX) and the L (wild strain) and LIIA (attenuated strain) of tobacco mosaic tobamovirus (TMV) were monitored in tomato (Lycopersicon esculentum Mill), cultivar GCR 236 (+/+) which were raised under greenhouse conditions at different seasons of the year in Japan. Symptoms expression, both in rapidly as well as in severity varied with the seasons among the treatments.
A study of the problems and prospects of fish farming was conducted in Kwara State. Questionnaires were used to collect data from Fish farmers, Traders and Civil Servants. The response showed that the major constraints to fish farming were lack of funds to procure land, water supply to farmers, unstable prices of feeds and fingerlings and poor management of the ponds. Fish farming has many prospects which include: enhancing the income of the farmer, nutritionally.
Field and screen house experiments were conducted during the 1997 cropping season at the University of Ilorin, Nigeria. The experiments designed as 2 x 5 factorial and laid out in split-plot were to compare responses of field- and pot-grown maize varieties to N fertilizer application. Two open-pollinated maize varieties (DMRSR-Y and TZBP-W) were evaluated at five N levels (0, 30, 60, 90 and 120 kg N ha-1) in both the field and the controlled environment.
