Real and potential environmental quality problems have accompanied the changes in agricultural productivity in recent decades. The development of agriculture has given rise to negative environmental impacts as large quantities of fertilizers and pesticides are used in modern agriculture to...

Soil degradation is a major constraint in most sub-Saharan African countries. short fallow rotations of 1-3 years have a potential to increase maize yield without additional inorganic nitrogen fertilizers. The mechanisms responsible for improved maize yield are partially understood. therefore the...

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...

Bambara groundnut (Vigna subterranean (L.) Verde.) is an indigenous African Leguminous crop, cultivated mainly by small-scale farmers in Zambia. The crop is grown predominantly for human consumption although it has potential for use in animal feeds and in many farming systems for soil amendments...

The objective of the study was to investigate the effect of planting date and plant population density on grain yield of two varieties of mungbean (Vigna radiata (L) Wilczek). It was carried out at the Natural Resources Development College Farm(Lusaka) during the 1995/96 rainy season.A...

Tomato (Lycopersicon lycopersicum L) production among the subsistance farmers in Zambia virtually stops during the rainy season and in low during the dry season. Field trials were carried out during the rainy and dry seasons at Zamseed farm, Lusaka, Zambia to detrmine the effects of different...

A study was conducted in the glasshouse to investigate the effects of soil type, watering interval, planting depth, and crust formation on emergence and seedling establishment of sorghum. Three separate pot experiments were conducted using three soil types and sorghum as a test crop. Various...

A trial was conducted at two sites, Lilayi Farm using no-tillage system and Ellensdale Farm using conventional tillage. The objective was to assess the efficacy of new herbicides under Zambian conditions so as to' provide recommendations for effective herbicides. Ten treatments were used at both...

A study was conducted at Lilayi farm in a no-tillage crop production system. The objective of the study was to assess the efficacy of new herbicides in a no-tillage soybean cultivation system in Zambia. Eleven treatments were used in this study. These include four preemergence, five postemergence...

On-farm experiments were conducted in the 1992-93 cropping season at Kasisi and Mufubushi. The objective of the experiment was to test alternative weeding methods to the present use of the hand hoe, for weeding in rain fed wheat production in Zambia. Six weed control treatments were used and...
