Radical veld improvement in South Africa with special reference to the Highland sourveld of Natal.
(1970)No abstract available. -
The development of cultivated dryland grass pastures for livestock production in the high rainfall areas of Rhodesia.
(1979)No abstract available. -
An assessment of Coastcross II Bermudagrass and kikuyu for growing out young beef animals.
(1983)The immediate aim of this study was to relate herbage availability, liveweight gain and stocking rate to one another under continuous and rotational grazing so that management recommendations could be formulated for ... -
Control of bush encroachment with fire in the arid savannas of Southeastern Africa.
(1983)No abstract available. -
Beef production from kikuyu and Italian ryegrass.
(1985)Four grazing trials to characterise cultivated pastures, in terms of beef production, were conducted in Bioclimate 3 of Natal. Dual purpose and British beef type cows were run on kikuyu at stocking rates ... -
Ecological effects of fire in the montane grasslands of Natal.
(1985)Although controlled burning has been used to manage Highland Sourveld grasslands, little was known of its effects on the vegetation. This study examined the effects of past fire treatments on veld condition,species ... -
Potential of established pastures in the winter rainfall region.
(1986)The seasonal production of 11 pastures was evaluated in dryland and irrigated trials at eight sites in the Winter Rainfall Region. These data were related to ... -
An evaluation of irrigated ryegrass/clover pastures for fat lamb production in the Highland Sourveld of Natal.
(1986)The primary objective of this study was to increase net farm income in the Highland Sourveld of Natal by developing pasture based fat lamb production systems. Secondary objectives included (a) determination of ... -
Studies of the management of grazing resources on the Makatini Flats and Pongolo River Floodplain.
(1988)Subsequent to the impounding of the Pongolo river in the 1970's, development of irrigated agriculture on the Makatini flats has been reducing the area of vegetation available for grazing, and flooding patterns on the ... -
Soil loss and run-off in Umfolozi Game Reserve and the implications for game reserve management.
(1988)Two management blocks were set aside in Umfolozi Game Reserve (UGR) to compare different management approaches. In one, the non-cull block, a noninterventionist policy was followed and no large mammals ... -
Factors affecting the seasonal variation of veld quality in South Africa.
(1988)This project was initiated to investigate the factors affecting the seasonal variation of veld quality in South Africa, with specific objectives as follows: (1) to establish what factors might play a role in seasonal ... -
The development of stocking rate models for three veld types in Natal.
(1990)The overall objective was to develop stocking rate models for three veld types. namely the Lowveld. the Southern Tall Grassveld and the Natal Sour Sandveld. in Natal. Sub-objectives were to determine ... -
The seasonal patterns in plant quality in various ecological zones in Natal.
(1990)The objectives of this study required that the following investigations be undertaken: 1) to determine if plant quality can be altered by modifying growing conditions; 2) to quantify the seasonal trends in plant quality ... -
The responses of grasses to fire and bush clearing in the Hluhluwe Game Reserve.
(1992)Contemporary and historical studies of the flora of the Hluhluwe Game Reserve (HGR), have emphasised the woody component whilst little work has been performed on the herbaceous vegetation. This is particularly true with ... -
Development and testing of a remote controlled oesophageal fistula valve for goats.
(1993)A remote control sampling technique was developed for the collection of oesophageal fistula samples from goats. Number and size of samples can be varied and collected throughout the day without disturbing the animal's ... -
Towards formalized adaptive management in succulent valley bushveld.
(1993)This study was designed to provide the means for implementing formal scientific vegetation management 1n the succulent valley bushveld of the eastern Cape, South Africa. Nowhere in the world has a detailed, ... -
Short-term effects of mixed grazing by cattle and sheep in highland sourveld.
(1994)Data derived from a long-term grazing trial were used to determine short-term effects of mixed grazing by cattle and sheep in Highland Sourveld. Five cattle to sheep ratio treatments (viz. 1 :0, 3:1, 1 :1, 1 :3, 0:1) ... -
The influence of fertiliser nitrogen on soil nitrogen and on the herbage of a grazed kikuyu pasture in Natal.
(1994)The work reported in this thesis was designed to develop a better understanding of the fate of fertiliser nitrogen applied to a tropical pasture under field conditions, with the eventual objective of ... -
The bioeconomic implications of various stocking strategies in the semi- arid savanna of Natal.
(1994)Climatic and market uncertainty present major challenges to livestock producers in arid and semi-arid environments. Range managers require detailed information on biological and economic components of the system in order ... -
Managing Lolium perenne L. (perennial ryegrass) in a sub-tropical environment in KwaZulu-Natal, South Africa.
(1994)Lolium perenne L. (perennial ryegrass) generally fails to persist under the sub-tropical cpnditions of South Africa. Furthermore, little research data are available on how to manage this species locally. ...
