Simultaneous intercropping is a crop-management strategy that is applied by the majority of small-scale farmers in the derived savanna of West Africa. Developing improved systems that are close to farmers' practices is likely to lead toadoption. This paper report economic results from a 2year on-...

Most of the farmers in the dry savannas of West Africa 'plant local varieties of cowpea, millet, sorghum, and groundnut in various intercropping systems with little or no purchased inputs. In this system, the cowpea and groundnut yields are low due to shading by cereals and lack of plant protecti...

Cowpea (Vigna unguiculata) [L.] Walp.) is a major component of the traditional cropping systems in Africa, Asia, and Central and South America where it is widely grown in mixtures with other crops in various combinations. The productivity of cowpea in these mixtures is low, mainly due to low plan...

This paper is comprised of five parts. The first part discusses the role of legumes in sustainable soil management and crop-livestock production. In this part, strategic use of legumes, selection of forage legumes to sub-optimal soil conditions, use of appropriate rhizobium, response of legumes t...

A large proportion of the maize planted in the tropics and highlands of Latin America is associated with beans and other crops. Agronomic research generally has focused on the improvement of varieties and hybrids, and the development of systems and technology for monoculture. The high production ...

Autor: Davis, J.H.C.

Maize and climbing beans are traditionally planted in association in the sierra regions of L.A. with alt. higher than 1500 m. The system has shown a series of advantages: low incidence of certain pests and diseases, less root lodging in maize, and less risk for the farmers. The types of climbing ...

CIAT has developed a new intercropping technology (cassava/grain legume associations) that tries to solve the numerous problems that arise in traditional intercropping systems. High-yielding cassava cv. with an erect, late-branching growth habit are recommended to minimize intercrop competition. ...

Results obtained in expt at CIAT are analyzed 20 maize hybrids were planted in 4 replications for 2 seasons, in monoculture and in association with bean genotypes P566 and P589, types II and IV (bush and climbing). In monoculture, Tropical White Mix gave the more than yield in both seasons (7.26 ...

Studies of planting dates, densities and patterns in maize bean associations were conducted in Colombia. An efficient methodology is needed to gain a better understanding of maize/bean systems and other crop combinations. The ideal system should minimize competition among the crops (for light, wa...
