Seasonal uptake and distribution of nutrient elements by kiwifruit vines 2. Micronutrients
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: W. A.G. Kotzé --- , Republic of South Africa Johanna de Villiers --- , Republic of South AfricaUptake and distribution of micronutrients by kiwifruit vines (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson var. deliciosa) cv. Hayward were studied in sand culture. The period of rapid accumulation of different micronutrients differed substantially. Zinc was accumulated mainly... -
Nutrient inflow to the roots of irrigated wheat throughout the growing season under semi-arid climatic conditions
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C.C. du Preez --- Department of Soil Science, Republic of South Africa A. T.P. Bennie --- Department of Soil Science, Republic of South AfricaThe objective of this study was to obtain information on the inflow of N, P, K, Ca, Mg, S, Cu, Fe, Mn and Zn to the roots of wheat (Triticum aestivum L.) grown under normal irrigation farming conditions. Except for... -

Item type: Journal Article • Journal: South African Journal of Clinical Nutrition • Authors: G Mphwanthe --- Department of Human Nutrition and Health, Malawi AA Kalimbira --- Department of Human Nutrition and Health, Malawi NC Geresomo --- Department of Human Nutrition and Health, MalawiObjective: The objective of the study was to determine the amount of home-fortified maize flour products consumed and wasted by women aged 15–49 years, and children aged ≤ 5 years. -
Effect of phosphorus and nitrogen sources on essential nutrient concentration and uptake by maize (Zea mays L.) during early growth and development
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Pieter-Ernst Coetzee --- Department of Soil, Crop and Climate Sciences, South Africa Gert M Ceronio --- Department of Soil, Crop and Climate Sciences, South Africa Chris C du Preez --- Department of Soil, Crop and Climate Sciences, South AfricaIn South Africa, maize is often produced on highly weathered soils with low organic matter contents. These soils are unable to supply sufficient nitrogen (N) and phosphorus (P) for sustainable maize production, resulting in the use of fertiliser sources containing... -
The effect of conditioning Acacia mearnsii De Wild. hedge-plants under shadenetting on rooting, elemental uptake and productivity of cuttings
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Sascha L Beck-Pay --- Institute for Commercial Forestry Research, University of KwaZulu-Natal, South Africa Mark D Laing --- Discipline of Plant Pathology, School of Agricultural Earth and Environmental Sciences, South AfricaAcacia mearnsii is a commercial forestry tree in South Africa, largely grown from open-pollinated seeds. Clonal deployment of superior selections of the species is restricted due to its poor rooting ability. The effects of conditioning parent hedge-plants under three levels... -
A comparison of zinc sources and extraction methods on sandy soils suitable for maize cropping
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: CF Wessels --- , South Africa LF van Straaten --- , South Africa CC du Preez --- , South Africa GM Ceronio --- , South AfricaMaize is the most important crop produced for human and animal nourishment in South Africa. The crop is susceptible to zinc (Zn) deficiencies, which result in lower grain yields with poorer nutritional value. Knowledge of the nature and behaviour of... -
Magnesium and zinc fertilisation improves rice yield and yield component responses to nitrogen, phosphorus, and potassium
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Firmin N Anago --- University of Abomey-Calavi, Benin Emile C Agbangba --- University of Abomey-Calavi, Benin Brice C T Oussou --- National Institute of Agronomic Research of Benin, Benin Gustave D Dagbénonbakin --- National Institute of Agronomic Research of Benin, Benin Lucien G Amadji --- University of Abomey-Calavi, BeninThe aim of this study was to assess the effects of magnesium (Mg) and zinc (Zn) on the response of rice to nitrogen (N), phosphorus (P), and potassium (K) application. Two sets of field experiments were carried out in Benin...
