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...

In assessing the efficacy and economic value of intercropping cabbage as a way of managing Diamondback moth (DBM), Plutella xylostella L., six cropping cultures were evaluated. The trial was conducted at the National Irrigation Research Station, in Mazabuka, Zambia, in 1995/96. The cropping...

Two experiments were conducted to investigate the efficacy of different nutritional supplements on productive performance of broilers. Parameters considered included growth rate, feed consumption, feed efficiency, mortality and the economic feasibility of using the commercial supplements....

A field experiment was carried out during the 1994/95 growing season at the Zambia Seed Company (ZAMSEED) farm (located at longitude 28" 18' E and latitude 15" 19' S) to evaluate 12 selected sorghum genotypes for forage/silage yield and quality; and to determine the effect of growth stages at...

Wheat is increasing becoming an important staple food crop in Zambia particularly in the urban and per-urban communities where shift in food tastes and preferences to wheat products has occurred. Production and yield are however severely limited by cost of irrigation water and nitrogen...

Information on genetic variability and stability of yield and yield components of sunflower in Zambia is lacking. The study was undertaken to determine the magnitude of yield; determine the relationships between yield and it's components; and estimate the heritability and stability of important...

An ecological study was undertaken over a period of one and half years in miombo woodland found in Serenje District, Zambia in order to determine the extent of woodland degradation in the study area as well as determining the avifauna community structure in the study area, and how it responds to...

Alley cropping offers great potential for increased and sustained crop production. However, there is currently limited understanding of the effects of maize/leucaena interactions on water distribution. A field trial was conducted to investigate the distribution of soil water and performance of...

Increasing yield through selection for yield per se in most Agricultural Crops has been difficult to achieve since yield is quantitatively inherited with low heritability. A field experiment was carried out in 2010/11 growing season at Sebele, Gaborone, Botswana on twelve tomato genotypes...

Common beans (Phaseolus vulgaris L.) is one of the most important legume crops in Zambia as a source of protein and income for most resource poor people in both rural and urban set-ups. It contains a higher percentage of protein as compared to maize, rice and cassava. However, common beans is...
