Joint effects ofn pre-selection mating system (RA) and percent truncation selected(20%;50%;0%(control) were studed in a 2x2x3 factorial experiment with 5 replicates to examine direct response to selection for pupal weight(PW), and correlated responses for larval weight(LW) and papation time(PT)in...

Greenhouse and field studies were conducted to evaluate manure extracts and their effect on crop yield and selected soil chemical and microbial properties. For the green house study, comfrey and tithonia plant materials were each used at rates of 0.0625, 0.0935, 0.125 and 0.156 kg per litre of...

The effects of 0%, 10%, 20% and 30% maize bran levels in broiler finisher diets, on the performance of Arbor acres and Cobb 500 broilers was investigated. Diets containing different levels of maize bran were introduced at 29 and 35 days of age. The test diets were fed ad lib up to the 47th day of...

Two potato cultivars, ‘Norchip’ and ‘Russet Burbank’ were used to study the changes that occur in potato tubers during growing season and through storage. In addition, the post harvest effects of bruising, chemical treatment (CIPC) and CO2 build-up in storage bins on the quality of stored tubers...

A study was conducted to determine the effect of substrate pasteurization and sterilization on the yield of Pleurotus cornucopiae and Pleurotus sajor-caju, and on the suitability of sorghum, wheat and maize grains, and wooden sticks as mycelium carriers in spawn production. The Pleurotus species...

This study was designed to determine the effectiveness of using azolla in rice fields and to investigate the appropiate time and quantities of azolla to be incorporated. The trial was conducted at the University of Zambia Field Station as a pot experiment. Three different quantities of azolla...

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...

A field trial was conducted at Mt. Makulu Research Station in Chilanga, Zambia to determine the effect of seed tuber size and plant spacing on the yield, dry matter content and daughter tuber sizes of three potato varieties. The trial was also meant to determine the combination of seed tuber size...

In this dissertation, I argue that the rating system of the Rhodesia Railways and the customs agreements concluded by Northern Rhodesia contributed to the failure of settler maize and cattle farming along the line of rail in Northern Rhodesia. Settler agriculture in Northern Rhodesia developed...
