A study was conducted to determine the net carbon sequestration potential of citrus to mitigate climate change. Perennial crops such as citrus have the potential to absorb and sequester carbon dioxide from the atmosphere, save for the carbon released back through the application of agro-chemical...
Download PDF ↓Green houses provide opportunity for year round crop production. Although tomatoes are an option for utilizing greenhouse space, performance of tomato under these conditions has potential limitations which may include root restriction and its attendant impacts such as artificial media effects on...
Download PDF ↓The before-and-after study design (also known as the pre and post-test design) was carried out with objectives of (i) determining the potential reduction in greenhouse gas emissions associated with changing pig manure management systems from the use of slurry pits (baseline emissions) to...
Download PDF ↓Wheat is an important economic cereal crop used in the production of a wide range of foods and other products. However, due to low wheat production (< 1.5 ton/ha) in acidic soils, and the country’s total demand of about 240,000 metric tones as at 2010, is unable to be met. Acid soils generally...
Download PDF ↓There are concerns about increasing incidence of sulphur (S) deficiency in agricultural soils due to increased cropping intensity, development of high yielding crop varieties and the use of S-free fertilizers. Zambia recorded cases of S deficiency in the 1950's and subsequently noticed grain...
Download PDF ↓A study was conducted in Magobbo area of Mazabuka District to validate the yield predicting capacity of the Zambia Semi-quantified Land Evaluation System for rain fed maize production under small-holder farming conditions. An area where soils had been surveyed and mapped was used as a test site....
Download PDF ↓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...
Download PDF ↓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...
Download PDF ↓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...
Download PDF ↓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...
