Evaluation of the Ceres-maize model in the simulating maize (Zea Mays L)growth, development and yield at different planning dates and nitrogen rates in a subtropical environment of Zambia
(University of Zambia, 2014)
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 ...
Combining ability for early maturity in maize (Zea mays L) under drought and low nitrogen conditions
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 ...
Inheritance of resistance to grey leaf Spot and nitrogen utilisation efficiency in Maize (Zea Mays L.)
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 ...
Response of maize (Zea Mays L.) cultivars to single weeding methods at different crop developmental stages
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 ...
Effects of environment on pollen-silk synchronisation in maize hybrid seed production
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 ...
