“…Most multiple cropping researchers were trained in reductionist science and began to look at components of systems. Research at the Centro Internacional de Agricultura Tropical (CIAT) in Colombia focused on maize and bean genotypes for intercropping, relative densities and planting dates, and physical orientation of different maize and bean combinations 7 , 8 . Important to these breeding programs was the study of genotype by system interactions, since unique adaptation of intercropping would signal the need for separate breeding or at least testing programs in complex systems 9 .…”

Results from research on controversial topics are often interpreted according to the world view of the reader. With conflicting results from different researchers or institutions, it is likely that vested financial interests or adherence to conventional wisdom will lead to rejection of science-based conclusions. An example from the past is the comparison of multiple cropping with monocrop systems, where clear advantages of complex systems are discounted by those committed to the monoculture paradigm. A current example is comparison of organic with conventional farming systems and food products, where food price, suspicion about certification and philosophy about perceived ‘non-scientific’ results cloud the technical conclusions. An emerging example is comparisons of local versus global food systems, where multiple issues including comparative advantage and food preferences obscure the key questions of energy investment, food equity and local well-being. A proposed solution to this dilemma is to instead focus scarce research funds on improving the development of alternative agroecosystems, rather than invest human energy into futile comparisons that are unlikely to convince the skeptics. In this way, more creative alternatives can be explored and greater progress made toward food equity and sufficiency.

“…All of the associated beans yielded significantly less than the beans in the two monoculture treatments. The monoculture bean yields were representative of the potential of this cultivar, although higher yields have been reported (Francis et al, 1978a). Bean yields did not differ when the climbing beans were entrained either within or between the beds in monoculture.…”

Figure kl. Total leaf area index in Type II and Type IV 2kS intercrops and in maize monocrops at 40,000 and at 55,000 plants per hectare * * * Beans and maize are staple food crops in many parts of Latin America, where they are predominantly produced in intercropped systems. It is common 1 y observed that bean yields are reduced by the presence of the maize, although the maize itself is little affected. The objective of my research was to investigate the physiological bases for the depressive influence of the maize on bean yields, in the first experiment, bean growth and yield responses were quantified and compared in monoculture and in association with maize. I hypothesized that maize affected bean growth by competing for resources, in space and over time. These hypotheses were tested in the remaining three seasons.
