Drought is a major constraint to common bean (Phaseolus vulgaris L.) production, especially in developing countries where irrigation for the crop is infrequent. The Mesoamerican genepool is the most widely grown subdivision of common beans that include small red, small cream and black seeded vari...


Blair, Matthew W.Galeano, CarlosTovar, EduardoMuñoz Torres, Mónica CeciliaVelasco, AlejandroBeebe, Stephen E.Rao, Idupulapati M.[Development of a Mesoamerican intra-genepool genetic map for QTL detection in a drought tolerant x susceptible common bean (Phaseolus vulgaris L.) cross]Development of a Mesoamerican intra-genepool genetic map for QTL detection in a drought tolerant x susceptible common bean (Phaseolus vulgaris L.) cross

A study was conducted to identify the most productive cultivars and their cutting management to optimize nutrient productivity in semi-arid areas of Rwanda. Four cultivars of Brachiaria brizantha (Piatá, MG4, Marandú and Xaraes), two cultivars of Brachiaria humidicola (Llanero and Humidicola), tw...

Beebe, Stephen E.Rao, Idupulapati M.Polanía Perdomo, José A.Grajales, Miguel A.Cajiao V., César Hernando[Improved harvest index in drought resistant common beans and possible effects on combining ability]Improved harvest index in drought resistant common beans and possible effects on combining ability

Nitrogen (N), the most critical and essential nutrient for plant growth, largely determines the productivity in both extensive and intensive grassland systems. Nitrification and denitrification processes in the soil are the primary drivers of generating reactive N (NO3-, N2O and NO), largely resp...


Subbaraoa, Guntur V.Rao, Idupulapati M.Nakahara, K.Ando, YasuoSahrawat, Kanwar LalTesfamariam, T.Lata, Jean-ChristopheBoudsocq, S.Miles, John W.Ishitani, ManabuPeters, Michael[Nitrogen management in grasslands and forage-based production systems—Role of biological nitrification inhibition (BNI)]Nitrogen management in grasslands and forage-based production systems—Role of biological nitrification inhibition (BNI)

Background: Agriculture is the single largest geo-engineering initiative that humans have initiated on planet Earth, largely through the introduction of unprecedented amounts of reactive nitrogen (N) into ecosystems. A major portion of this reactive N applied as fertilizer leaks into the environm...

Human activity has had the single largest influence on the global nitrogen (N) cycle by introducing unprecedented amounts of reactive-N into ecosystems. A major portion of this reactive-N, applied as fertilizer to crops, leaks into the environment with cascading negative effects on ecosystem func...

Agriculture and livestock production systems are two major emitters of greenhouse gases. Methane with a GWP (global warming potential) of 21, and nitrous oxide (N2O) with a GWP of 300, are largely emitted from animal production agriculture, where livestock production is based on pasture and feed ...

Low nutrient availability, especially phosphorus (P) and nitrogen (N) supply is the major limitation to forage production in acid infertile soils of the tropics. A field study was conducted at the farm ‘La Es- peranza’ located in Mondomo, Department of Cauca, in the coffee growing zone of Colombia...

the Quesungual Slash and Mulch Agroforestry System (QSMAS) on the dynamics of soil nitrogen (N) and phosphorus (P), and their impact on QSMAS’ productivity in southwestern Honduras, Central America. Five land use systems were compared: (l) Slash-and-burn traditional system; (2, 3 and 4) QSMAS of ...
