The effects of litter quality and inorganic nitrogen (N) on rate of decomposition and N release pattern by three leguminous woody species were investigated under field conditions by the litterbag technique. The species studied in 1994/1995 were Leucaena leucocephala, Senna siamea and Flemingia...
This study was carried out during the 1993 /94 cropping season at the University of Zambia (UNZA) Farm and Lusitu Sub-Research Station which are situated in Agroecological Zones II and I (medium and low rainfall), respectively. The objective was to determine the nitrogen fertilizer requirement...

Its increased production is hampered by several foliar diseases of which the anthracnose caused by Collectotrichum truncatum appear to be the most prevalent, than red leaf blotch cause by Dactuliochaeta glycines reported...
Download PDF ↓The purpose of this study is to construct and estimate a model of production behavior for tobacco farmers in Zambia. The final data set consisted of annual production and price data for fifty farmers over three seasons (1990/91 to 1992/93). Production behavior is modeled in terms of a Translog...
