Crop simulation models can accurately predict yield with a priori knowledge of the soil properties and crop management practices. Generation of new information through traditional agronomic research practices is not sufficient to meet the needs for new agro-technologies and they are generally...
Download PDF ↓In maize hybrid seed production, the objective is to maximise seed yield of desirable seed grade that is saleable and genetically pure. To achieve this, the timing of pollen shed of the male and silking of the female should be well synchronised. Currently, maize hybrid seed production is based on...
The unpredictable rainfall patterns increased the demand for early maturing maize cultivars. The two most limiting production constraints in maize are drought and low nitrogen. In most national breeding programs in Southern Africa there are no early maturing testers for use in the early phases of...
Download PDF ↓Maize is an important staple and cash crop in Zambia. Abiotic and biotic stress conditions, particularly low soil fertility (low nitrogen) and grey leaf spot(Cercospora zeae- maydis), reduce maize yields. Most varieties developed by the Zambian National Maize Programme have neither resistance to...
It has been reported that 50 to 95% of small-scale maize (Zea mays L.) farmers weed their fields once during the growing season. The weeding is done at either 2-3 leaf or 7-8 leaf time of weeding. Farmers using hoes dig up the weeds, shake off the soil and either leave the weeds to dry in the...
