(Taylor & Francis Group, 1995-04-01)This study was conducted to compare pod and seed characteristics, nutritive value, digestibility and seed survival of intact medic pods after ingestion by sheep. Different diets comprising the intact pods of six cultivars ...
-
(Taylor & Francis Group, 1994-04-01)A plotless vegetation sampling technique (ellipse‐intercept method) is described and its accuracy and precision compared by simulation models with two other line‐based techniques: line‐intercept and a point‐intercept method ...
-
(Taylor & Francis Group, 1996-12-01)The purpose of this paper is to describe the use of satellite remote sensing and GIS techniques in applying a localised range condition assessment methodology based on fence‐line contrasts. The approach was to compute six ...
-
(Taylor & Francis Group, 1996-04-01)The performance of lactating dairy cattle fed on a maize silage (S) dry‐lot scheme was compared with that of lactating dairy cattle switched abruptly from a dry‐lot regime to graze endophyte‐free Johnstone (J), Kentucky ...

(Taylor & Francis Group, 1994-04-01)Edited by J.C. Noble & R.A. Bradstock pp. viii + 485 CSIRO, Australia, 1989. ISBN 0 643 04985 1
-
(Taylor & Francis Group, 1994-08-01)A point‐based technique was used to determine the effects of grazing, due to stocking rate and cattle‐to‐sheep ratio, on the defoliation pattern of three grass species. At each of 100 systematically located points per ...
-
(Taylor & Francis Group, 1993-12-01)A step‐wise approach was followed towards the design of a monitoring system for the herbaceous layer on the escarpment of the Drakensberg mountains in the Transvaal, South Africa. The parameter of concern was proportional ...
-
(Taylor & Francis Group, 1993-12-01)A Lolium multiflorum cv. Midmar pasture and ninety individual plants (both Italian and Westerwolds types), from 15 different Lolium multiflorum cultivars in a spaced‐plant trial, were assessed for total nonstructural ...
-
(Taylor & Francis Group, 1993-08-01)Tswana steers were continuously grazed at stocking rates of 3, 6, and 9 ha LSU‐1 in two blocks, and steers in one block were supplemented with phosphorus. Dry matter yield of herbaceous rangeland plants was measured at the ...

-
(Taylor & Francis Group, 1996-08-01)The effect of plant density (row spacing / seeding rate), cultivar choice, nitrogen (N) fertilization and close‐down date on the number of reproductive tillers surviving to maturity in tall fescue (Festuca arundinacea ...
-
(Taylor & Francis Group, 1996-08-01)The effect of plant density (row spacing / seeding rate), nitrogen (N) fertilization, cultivar choice and close‐down date on tiller initiation in tall fescue (Festuca arundinacea Schreb.), managed for seed production, was ...

-
(Taylor & Francis Group, 1993-04-01)The relation between above‐ground phytomass production and three independent variables, namely, seasonal rainfall, evapotranspiration (Et) and veld condition, were investigated using fourteen years’ data (1977–1991) from ...
-
(Taylor & Francis Group, 1993-12-01)Two experiments designed to establish possible reasons for the often‐observed low voluntary feed intake of animals grazing kikuyu pastures were conducted at two widely differing locations. Low digestibility and low rate ...
-
(Taylor & Francis Group, 1996-12-01)Seedling emergence, survival and species composition were recorded on vegetation subjected to seven practicably feasible soil and defoliation treatments. Soil disturbance, with defoliation removal, produced the greatest ...
-
(Taylor & Francis Group, 1996-08-01)Quantification of the potential ingestion rates of different grasses is important for modelling purposes but is difficult to achieve under field conditions. The ingestion rates of the sourveld species Alloteropsis semialata, ...
-
(Taylor & Francis Group, 1996-12-01)Selective grazing by livestock inevitably results in patch grazing. This study was initiated to determine the effects of patch grazing on (1) the vigour of a single grass species, Themeda triandra, and of the sward, and ...
