Photosynthate remobilization capacity from drought-adapted common bean (Phaseolus vulgaris L.) lines can improve yield potential of interspecific populations within the secondary g... por Klaedtke, SM, Cajiao V., César Hernando, Grajales Bedoya, Miguel Angel, Polanía Perdomo, José A., Borrero, Gonzalo, Guerrero, A., Rivera, M., Rao, Idupulapati M., Beebe, Stephen E., León, J.

“…Interspecific lines obtained from crosses between common bean (Phaseolus vulgaris L.) and other species from its secondary gene pool have a tendency for excessive vegetative growth and low grain yield. Contrariwise, drought-adapted common bean lines have been observed to produce high yields despite low shoot biomass production. …”

Utility of basic research in plant/crop physiology in relation to crop improvement : A review and a personal account por El-Sharkawy, Mabrouk A.

“…In most of these countries, agricultural production exceeds national demand, resulting in excess products for export. In many of the developing countries, however, agricultural productivity is still far below what it should be because of multiple technical and socio-economic constraints. …”

Nutrient recycling from organic wastes through viable business models in peri-urban areas in Sub-Saharan Africa por Danso, George K., Drechsel, Pay

“…The analysis showed that from the city perspective cost savings are only possible if large volumes of waste can be composted to reduce waste transport costs while compost sale (and agricultural use) is not a necessity from the perspective of cost savings. In fact, despite much interest the farmers’ willingness to pay remained limited at the reservation price of US$5 per 50 kg bag. …”
