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...

Under increased population pressures, extensive methods of arable cultivation give way to intensive ones. The whole agricultural policy area then becomes central in influencing and further determining production trends and, consequently, the farming system that evolves. In most developing...

The seed yield of sesame in Zimbabwe is low compared to other countries, yet the crop is gaining in economic significance. A trial was therefore conducted at Gwebi, Zimbabwe, to evaluate the effects of plant population and fertilizer nitrogen rate on the yield and yield components of sesame...

Maize is an important staple and cash crop in Zambia. Abiotic and biotic stress conditions, particularly low soil fertility (low nitrogen) and grey leaf spot(Cercospora zeae- maydis), reduce maize yields. Most varieties developed by the Zambian National Maize Programme have neither resistance to...

Land, which includes the surface of the earth, the airspace above it and everything beneath the surface down to the centre of the earth, is the source material wealth. As human beings we live on the earth and obtain from it food, clothing, fuel, shelter, metal and precious stones. Even when we...

The land has been the ultimate source of nourishment and origin of man and other living organisms. Man has depended and still depends on plants and animals for his survival. These in turn depend on the earth and other organisms. The cultivation of crops has been known to man for a long time, and...

It has been reported that 50 to 95% of small-scale maize (Zea mays L.) farmers weed their fields once during the growing season. The weeding is done at either 2-3 leaf or 7-8 leaf time of weeding. Farmers using hoes dig up the weeds, shake off the soil and either leave the weeds to dry in the...

The land tenure system of any given country has a long term impact on the development of the agricultural sector. Hence for developing countries like Zambia which wish to diversify their economies through the promotion of the sector, the land tenure system must be moulded in such a way as to be...

The effect of vesicular arbuscular mycorrhiza (VAM) and rhizosphere pseudomonads on chickpea (Cicer arietinum L.) wilt caused by Fusarium oxysporum f. sp. ciceri (Matuo and Sato) in Zambia was investigated. Vesicular arbuscular mycorrhiza was isolated from three soils obtained from Kasama area of...

This study was designed to determine the influence of the maturity status on partitioning of photosynthate to the roots and nitrogen fixation in common beans (Phaseolus Vulgaris L.). Two experiments(glasshouse at the University of Zambia and field at the Zambia Seed Company farm, Ngwerere, north...
