Species and cultivar combinations have been relatively well studied, though little is known about the influence of spatial arrangement on agricultural or native plant mixtures. The effect of spatial pattern on mixtures was explored in three experiments. In the first two, agricultural and native plants were planted in two-way mixtures...

In the production of vegetable crops, good fertilizer usage is only one of the important management practices, including proper seeding, pest control, adequate irrigation, and timely harvest. Because of the influence of soil type, climatic conditions, and other cultural practices, crop response from fertilizer may not always be predicted accurately....
A series of four studies were conducted in Colombia, South America,
in the field and the greenhouse to determine the effect of plant
competition and mulching on carbohydrate and photosynthate distribution
and nitrogen fixation in beans (Phaseolus vulgaris L.).
Mulching beans (determinant growth habit) with rice hulls in the
lowland...
Nonchemical weed control strategies are in short supply in snap beans, particularly strategies that target weeds within the seed row. Recent work demonstrated the limitations of propane flaming and organic herbicides for weed control in stale seedbeds. There was very little improvement in weed control with propane flame or organic...
