“n Voorlopige evaluasie van eenjarige, wintergroen weidings met speenlammers, in die Oos‐Kaapse suurveld
Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa • Authors: T.G. Coetzee --- Departement van Landbou‐ontwikkeling (Oos‐Kaapstreek), Republiek van Suid‐Afrika G.R. Barnes --- Departement van Landbou‐ontwikkeling (Oos‐Kaapstreek), Republiek van Suid‐Afrika W.S.W. Trollope --- Agronomie Departement, Landboufakulteit, CiskeiA preliminary evaluation of annual, wintergreen pastures using weaned lambs in the eastern Cape sourveld. Animal production and feed availability on oats, vetch and oats/vetch pastures were evaluated under continuous grazing, at three stocking rates, using weaned lambs. The oats... -
Field response of three subtropical pasture legumes to lime, P and K on an acid sandy soil
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A.J. Kruger --- , Republic of South Africa V.D. Wassermann --- , Republic of South Africa A.J. van der Merwe --- , Republic of South AfricaA field study was undertaken to determine the response of Macroptilium atropurpureum cv. Siratro, Stylosanthes guianensis CM. Oxley and Aeschynomene falcata cv. Bargoo to lime P and K on an acid soil, very low in minerals. The trial extended over... -
Winter cover crops effects on soil strength, infiltration and water retention in a sandy loam Oakleaf soil in Eastern Cape, South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: HA Mupambwa --- Department of Agronomy, South Africa IIC Wakindiki --- Department of Agronomy, South AfricaThere is substantial evidence that cover crops increase soil fertility and plant nutrition but the few studies concerning soil physical properties are conflicting. This study determined the effects of monocultures of vetch (Vicia dasycarpa L.), lupin (Lupinus angustifolius L.), oats... -
Winter cover crops and fertiliser effects on the weed seed bank in a low-input maize-based conservation agriculture system
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: E Dube --- Department of Agronomy, Faculty of Science and Agriculture, South Africa C Chiduza --- School of Agricultural Sciences, Faculty of Agriculture, Science and Technology, South Africa P Muchaonyerwa --- School of Agricultural, Earth and Environmental Sciences, South Africa M Fanadzo --- Department of Agronomy, Faculty of Science and Agriculture, South Africa TS Mthoko --- Department of Agronomy, Faculty of Science and Agriculture, South AfricaThis study investigated the effects of grazing vetch (Vicia dasycarpa L.) and oat (Avena sativa L.) cover crops and fertiliser on the seed bank of some problematic weeds in a maize-based conservation agriculture system. Soil sampling for seed bank analysis... -
Influence of mono- and biculture cover cropping systems on soil polysaccharides and aggregate stability in a sandy loam Oakleaf soil in Eastern Cape, South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: HA Mupambwa --- Department of Agronomy, South Africa IIC Wakindiki --- Department of Agronomy, South AfricaMono- and biculture cropping systems are thought to affect aggregate stability by influencing soil polysaccharides but the exact relationship is uncertain. The objective of this study was to determine the effects of cover cropping systems on polysaccharides and aggregate stability... -
Conservation agriculture effects on plant nutrients and maize grain yield after four years of maize–winter cover crop rotations
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Ernest Dube --- Department of Agronomy, Faculty of Science and Agriculture, South Africa Cornelius Chiduza --- Department of Agronomy, Faculty of Science and Agriculture, South Africa Pardon Muchaonyerwa --- School of Agricultural, Earth and Environmental Sciences, South AfricaThe effects of maize rotation with oat (Avena sativa cv. Sederberg) and grazing vetch (Vicia dasycarpa cv. Max) winter cover crops on nutrient availability, maize grain yield and maize grain nutrient concentration were investigated. Soil samples were collected from the... -
Preliminary evaluation of the effectiveness of Rhizobium leguminosarum bv. viceae strains in nodulating hairy vetch (Vicia villosa) in the sandy soils of Zimbabwe
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Akinson Tumbure --- Soil Productivity Research Laboratory, Department of Research and Specialist Services, Zimbabwe Menas Wuta --- Department of Soil Science and Agricultural Engineering, Zimbabwe Farai Mapanda --- Department of Soil Science and Agricultural Engineering, ZimbabweHairy vetch (Vicia villosa Roth) is an introduced temperate forage legume in Zimbabwe that has no locally available commercial inoculant. In this study, Rhizobium leguminosarum bv. viceae strains MAR 1504, MAR 833 and MAR 346 available in Zimbabwe's strain bank... -
A vetch winter cover crop can improve response to nitrogen fertiliser and profitability of no-till maize
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Ernest Dube --- Department of Agronomy, Faculty of Science and Agriculture, South Africa Cornelius Chiduza --- Department of Agronomy, Faculty of Science and Agriculture, South Africa Pardon Muchaonyerwa --- School of Agricultural, Earth and Environmental Sciences, South AfricaA high nitrogen (N) fertiliser requirement can be a deterrent to the adoption of conservation agriculture (CA). A field trial was carried out to test whether a high biomass-yielding vetch (Vicia dasycarpa L.) winter cover crop can be used to... -
