Titre de série : Savana, 1 Titre : Productivity of crops in the savana and rain forest zones in Nigeria Type de document : texte imprimé Auteurs : Kassoum, A. H. ; Kowal, J. M. Année de publication : 1973 ISBN/ISSN/EAN : CI-04500 Note générale : Potential crop productivity in the savana and rain forest zones of Nigeria is assessed using dewit's model of gross photosynhesis and actual rates of dry matter production and economic yields of crops. Net potential photosynthesis is 20-40 per cent greater in the savana zone than in the forest zone. Rates of dry matter production and economic yields of some crops is the savana are twice as high as they are in the forest maximum.

Titre de série : Savana, 2 Titre : An assessment pf aridity and the severity of the 1972 drough in northern Nigeria and Neigh bouring countries Type de document : texte imprimé Auteurs : Kowal, J. M. ; Adeoye, K. B. Année de publication : 1973 ISBN/ISSN/EAN : CI-04514 Note générale : Agroclimatological parameters such as the annual rainfall, the start and end of the rains, the length of the rainy season and evaporation, are closely related to latitudinal position. These relationships are quantitative expessed en terms of regression equations, which are usuel to examine the causes and asess the severity of the 1972 drought in the drier zones of northern Nigeria and neighbouring countries of Niger and chad. A northern limit of arable farming based on the minimum requirements for the cultivation of millit is established along lat. 14.7°N.
