The study was conducted to determine and characterize grain yield, grain yield stability, uniformity of three way cross(TWC), single cross (SC) hybrids and open pollinated (OP) varieties of sorghum and relate their grain yield to morphological and physiological attributes via leaf area index and...

Maize (Zea mays L.) is an important crop in Zambia but it is being threatened by a number of foliar diseases. In Zambia, gray leaf spot caused by Cercospora zeae-maydis has become a serious foliar disease of maize in the last four years.The assessment of the variability of Cercospora zeae-maydis...

Soil acidity is a major constraint to crop productivity and lime, the primary amendment, is seldom effective when applied alone and it is not easily accessed by resource-poor farmers. Organic residues around the farm are seldom used as soil amendments. This study was conducted at the University...

Maize is a major staple food crop widely grown in Zambia. Low soil fertility and high cost of chemical fertilizers are some of the major factors limiting maize productivity. The use and integration of legume green manure species in the cropping system is an important alternative to inorganic...

Beans are an important crop in Tanzania grown by a wide range of farming communities. Its production, however, is very low due to various factors of which drought is becoming very important due to its frequency in the recent past. Provision of bean varieties that would withstand drought is...

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...
