Plant relations in mixtures of Trifolium subterraneum cv. Mt Barker and Lolium multiflorum cv. Midmar: II. Yield advantage as reflected in the Land Equivalent Ratio
Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa • Authors: M. van den Berg --- , Republic of South Africa A.J. Kruger --- , Republic of South AfricaLand Equivalent Ratios (LER) were calculated for mixtures of Trifolium subterraneum and Lolium multiflorum in terms of dry matter production and crude protein production. This ratio denotes the yield advantage, if any, of a specific mixture against the pure stands... -
Intercropping of beans (Phaseolus vulgaris L.) and sugar-cane: The effect of inter-specific competition on the growth of plant cane
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M. F.A. Leclezio --- Department of Crop Science, J.D. Lea --- Department of Crop Science, P.K. Moberly --- ,The competitive effects of intercropped beans (maturation period: three months) on the growth, tiller development and yield of plant sugar-cane (maturation period: 18 months) in the subhumid coast-hinterland of Natal were investigated over two seasons. In the first season rainfall... -
Methods of presenting intercropping results and preliminary results with Zea mays and Phaseolus vulgaris
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M.N. Austin --- Department of Agronomy, J.N. Marais --- Department of Agronomy,Replacement intercropping trials with maize and dry beans were conducted to provide information which could lead to a cropping strategy that would reduce the risk of rainfed crop production in the Ciskei. Attention is focused on the problem of analysing... -
A preliminary investigation of the potential for maize - legume intercropping in the semi-arid area of Sidamo region, Ethiopia. I. Maize response
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Y.B. Alemseged --- , Australia G.W. King --- , Australia L.R. Coppock --- International Livestock Centre for Africa, Ethiopia J.C. Tothill --- International Livestock Centre for Africa, EthiopiaAn intercropping trial involving four legumes, three maize planting densities and two legume planting times was undertaken at Dembela Wacho in the Sidamo region of Ethiopia during the 1987 growing season. The objective was to explore the potential of intercropping... -
A preliminary investigation of the potential for maize - legume intercropping in semi-arid area of Sidamo region, Ethiopia. II. Legume response
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Y.B. Alemseged --- , Australia G.W. King --- , Australia L.R. Coppock --- International Livestock Centre for Africa, Ethiopia J.C. Tothill --- International Livestock Centre for Africa, EthiopiaAn intercropping trial of maize (Zea mays) with two dual-purpose and two forage legumes was undertaken at Dembela Wacho in the Sidamo region of Ethiopia during the 1987 growing season. The objective was to explore the potential of intercropping in... -
Spatial variability of nitrate nitrogen in soil during the growing season of maize, cowpea and soybean
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A.A. Bloem --- Department of Agriculture, North West Province, Republic of South Africa R.O. Barnard --- Department of Plant Production and Soil Science, Republic of South AfricaThe nitrogen advantage of legumes in crop rotation systems is well known, but the nitrogen advantage from legumes to associated crops in an intercropping system is unclear. The objective of this study was to determine whether plant-available nitrogen is released... -
Grain yield response and Chilo partellus infestation in diverse sorghum-cowpea intercrop arrangements
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: K.K. Ayisi --- Department of Plant Production, Republic of South Africa M.S. Mposi --- Department of Plant Production, Republic of South Africa J. van den Berg --- , Republic of South AfricaYield improvement and insect pest control in intercropping systems relative to sole cultures has been variable and inconsistent over habitats, component species, varieties, density, row arrangement, soil fertility and moisture. This study was initiated to quantify yield response of two... -
Cropping System Intensification as a Management Method Against Vectors of Viruses Causing Maize Lethal Necrosis Disease in Kenya
Item type: Journal Article • Journal: East African Agricultural and Forestry Journal • Authors: E. S. Namikoye --- Department of Agricultural Science and Technology, G. M. Kariuki --- Department of Agricultural Science and Technology, Z. M. Kinyua --- Kenya Agricultural and Livestock Research Organization, M. W. Githendu --- Department of Agricultural Science and Technology, M. Kasina --- Kenya Agricultural and Livestock Research Organization,Maize Lethal Necrosis Disease (MLND) has emerged as a great threat to maize production in East Africa. It is caused by a synergistic infection of maize by sugarcane mosaic virus (SCMV) and maize chlorotic mottle virus (MCMV). This study was... -
Improving productivity of orange-fleshed sweetpotato (Ipomoea batatas) through intercropping with legumes and moderate phosphorus application
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Eliah Munda --- International Potato Center, Mozambique Petrus J Pieterse --- Department of Agronomy, South Africa Maria I Andrade --- International Potato Center, Mozambique Godwill S Makunde --- International Potato Center, Mozambique Engil I Pereira --- School of Earth, Environmental, and Marine Sciences, USASweetpotato yield is adversely affected by poor soil fertility in Mozambique where access to inorganic fertilisers is lacking. The objective of the study was to evaluate the effectiveness of intercropping sweetpotato with groundnut and soybean at various phosphorus (P) fertilisation... -
Forage yield, competition and economic benefit of intercropping cactus and millet with mulch in a semi-arid environment
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Marcondes de Sá Souza --- Universidade Federal Rural de Pernambuco, Brasil George do Nascimento Araújo Júnior --- Universidade Federal Rural de Pernambuco, Brasil Luciana Sandra Bastos de Souza --- Universidade Federal Rural de Pernambuco, Brasil Alexandre Maniçoba da Rosa Ferraz Jardim --- Universidade Federal Rural de Pernambuco, Brasil Gabriel Italo Novaes da Silva --- Universidade Federal Rural de Pernambuco, Brasil Gherman Garcia Leal de Araújo --- , Brasil Fleming Sena Campos --- , Brasil Maurício Luiz de Mello Vieira Leite --- Universidade Federal Rural de Pernambuco, Brasil José Nildo Tabosa --- Instituto Agronômico de Pernambuco, Brasil Thieres George Freire da Silva --- Universidade Federal Rural de Pernambuco, BrasilThis study aimed to quantify forage yield, economic performance, biological efficiency and competitive ability in cactus intercropped with millet, compared with their monocrops, both with and without mulch, under irrigation. The experiment was conducted over two years in semi-arid of... -
Lucerne establishment in dryland conditions: effects of crop residues and wheat as a nurse crop
