Summary

Incorporation of dry matter of perennial soybean into the soil, alone or with mineral fertilization, resulted in improved vegetative growth of common beans. Fairly high LAI was observed at flowering time where dry organic matter had been added, causing leaf self-shading and decreased growth in the later states of development. In contrast, both the control and mineral fertilized plots showed slower but continuous growth up to 50 days from plant emergence. Only slight differences in grain yield were noticed despite remarkable increases of Crop Growth Rate, Relative Growth Rate, Net Assimilation Rate, and Efficiency of Solar Energy Conversion that resulted from the application of dry organic matter.
