Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...

The relatively high level of fatty acids in soybean nodules and rhizobia from soybean nodules suggested that the glyoxylate cycle might have a role in nodule metabolism. Several species of rhizobia in pure culture were found to have malate synthetase activity when grown on a number of different carbon sources. Significant isocitrate lyase activity was induced when oleate, which presumably may a...

Bean breeding programs have focused on the generation of early bush cultivars with higher yields, commercial acceptance and resistance to crop-limiting diseases. This study prioritized nutritional quality in terms iron (Fe) zinc (Zn) content bean grains grown three high tropical environments. Two five climbing were evaluated. The mineral was determined atomic absorption spectroscopy. results in...

Lipid content has been determined for two types of lipid-rich vesicles isolated from bush bean cotyledon at 24 hr of germination. The larger, nonassociating vesicles are four to six times richer in triglyceride than the smaller vesicles which associate strongly among themselves, as well as with smooth membranes in the cell. The larger vesicles contain about 640 micromoles of phospholipid per gr...

Common bean (Phaseolus vulgaris L.) is the most important food legume, cultivated by small farmers and is usually exposed to unfavorable conditions with minimum use of inputs. Drought and low soil fertility, especially phosphorus and nitrogen (N) deficiencies, are major limitations to bean yield in smallholder systems. Beans can derive part of their required N from the atmosphere through symbio...
