Soil Organic carbon (SOC) because of its influence on all aspects of soil fertility, is a useful indicator of soil health and the performance of mixed farms, and increasing SOC can improve productivity, stability and resilience of the soil. Thus the overall objective of the study was to...

Zambia has soils with low plant available nutrients due to leaching, depletion of organic matter and acidification. One way of addressing this situation is by the application of organic materials such as aqueous neem leaf extract. No known documented research has been conducted in Zambia to...

Conservation Agriculture (CA) practice is reported to increase the level of total P in soil after a few years of cultivation with fertilizer application. Measures to ensure efficient utilization of the residual P in soil can, therefore, of great importance, especially in acid soils where the...

Leguminous tree leaf litter has potential as a nutrient source for smallholder vegetable production systems. However, quality of the leaf litter influences yield responses by the crops grown. A field experiment was conducted at Msekera Research Station in Eastern Province of Zambia to assess the...

Maize (Zea mays L.) is one of the most important cereal crops in the world after wheat and rice. It is the staple food crop of people in Zambia, but phosphorus (P) deficiency in soils has been limiting grain yield. The objective of this study was to introgress desirable yield enhancing alleles...

Maize (Zea mays L.) is one of the most important cereal crops in the world after wheat and rice. It is the staple food crop of people in Zambia, but phosphorus (P) deficiency in soils has been limiting grain yield. The objective of this study was to introgress desirable yield enhancing alleles...

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...

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....

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...
