Crop varieties have been developed for monocrop culture, and considerable progress has been made in increasing yield potential for those farmers who have put capital and available technology to work in the better agricultural regions. Agronomic trials with intercropped systems have concentrated on such variables as relative plant population of component crops, planting dates, fertilizer treatments, and spatial orientation of the crops. Photoperiod insensitivity allows the planting of a variety at any time during the year, and gives flexibility to new systems which require planting outside the traditional dates for a region and crop. The importance of maize-bean intercropping in the Latin American tropics makes it essential to consider these systems in the development of new germplasm. An understanding of present and potential cropping system is essential to successful genetic improvement of crop species. Literature Cited Aiyer, A. K. Y. N. 1949. Mixed cropping in India. Indian J.
