Purpose Coffee represents an important trade asset internationally. Around 70% of global coffee production is provided by 25 million smallholders farmers. In recent decades, coffee systems have been transformed into more intensified systems of coffee monoculture. The general objectives of this pa...

This review paper discusses the relevance and potential importance of food-feed systems in Asian agricultural systems, and in particular the role and contribution of legumes to these systems. A food-feed system is one that maintains, if not increases, the yield of food crops, sustains soil fertil...

Investigates the effects of improved surface drainage on the productivity of Vertisols in a wheat-and-chickpea cropping trial conducted in 1987 at ILCA;s Debre Zeit research site in the Ethiopian highlands. Chickpea plots were subjected to four irrigation treatments, viz, no irrigation, irrigatio...

Soil nutrient depletion as a result of continuous cultivation of soils without adequate addition of external inputs is a major challenge in the highlands of Kenya. An experiment was set up in Meru South District, Kenya in 2000 to investigate the effects of different soil-incorporated organic (man...

Oxisols such as those of the Colombian Eastern Plains (Llanos) are susceptible to physical, chemical and biological degradation once brought into cultivation, especially under intensive use of machinery. The main objective of this study was to determine the impact of intensive disc harrowing (2, ...

Cowpea-maize intercropping causes low yields of cowpea due to shading effect by maize plants. Staggering of dates of planting of cowpea in an intercrop is a potential way of reducing intercrop shading while increasing cowpea yield. Nonetheless, contrasting cowpea cultivars may have differential r...
