Titre : Agroclimatic contraints to up land rice production in west Africa Type de document : texte imprimé Auteurs : Lawson, L. T. Mention d'édition : IITA Editeur : IITA Année de publication : 1979 ISBN/ISSN/EAN : CI-10620 Note générale : Increasing areas of land are being brought under upland rice production in west Africa to meet an increasing demand for the grain, but yields have actually been showing a decline. The probable reason for the this failure to judiciously select the areas of production on the basis of a matching the physical attributes of the environments and the requirements of the crop. Careful selection of site, plant and cultural pratices, however still offer a viable approach to improving yield.

Titre de série : IITA Technical bulletin Titre : Role of mulching techniques in tropical soil and water management Type de document : texte imprimé Auteurs : Lal, R. Mention d'édition : IITA Editeur : IITA Année de publication : 1975 ISBN/ISSN/EAN : CI-10029 Note générale : Surface mulching with crop residue at the rate of 4 to 6 tons/ha decrease soil temperature and maintains favorable soil structure through enhanced biological activity. Continuous surface cover can be maintained by growing and least competitive cover crops or by the use of crop residue through rotation and tillage techniques. Mulch tillage such as minimum tillage based on the zonal tillage concept of maintaining crop residue in the inter-row zone and simultaneously providing a good seed bed meets most soil management requirements for many upland crops. Yields of maize, cowpeas, pigeon peas, soybeans and sweet potatoes on mulch tillage plots equal yields from plowed ploto. A the same time the soil erosion is minimal and soil structure is maintained by more intensive soil flora fauna activity.
