Evidence for biological nitrification inhibition in Brachiaria pastures

Autor: Subbaraoa, Guntur V. Nakahara, K. Hurtado, MP Ono, H Moreta Mejia, DE Salcedo, AF Yoshihashi, AT Ishikawa, T. Ishitani, Manabu Ohnishi, M Yoshida, M Rondón, Marco Antonio Rao, Idupulapati M. Lascano, Carlos E. Berry, W.L. Ito, O.

Nitrification, a key process in the global nitrogen cycle that generates nitrate through microbial activity, may enhance losses of fertilizer nitrogen by leaching and denitrification. Certain plants can suppress soil-nitrification by releasing inhibitors from roots, a phenomenon termed biological...

Changes in soil organic matter and phosphorus fractions under planted fallows and a crop rotation system on a Colombian volcanic-ash soil

Autor: Phiri, S Barrios, E. Rao, Idupulapati M. Singh, B.R.

Planted tree or shrub fallows can help increase the fertility of degraded tropical soils. We investigated the effects of planted fallows of Indigofera (IND), Calliandra (CAL), and Tithonia (TTH); a natural, unmanaged fallow (NAT); and a maize/bean rotation (ROT) on the dynamics and partitioning o...

Disc harrowing intensity and its impact on soil properties and plant growth of agropastoral systems in the Llanos of Colombia

Autor: Phiri, S Amézquita Collazos, Edgar Rao, Idupulapati M. Singh, B.R.

Oxisols such as those of the Colombian Eastern Plains (Llanos) are susceptible to physical, chemical and biological degradation once brought into cultivation, especially under intensive use of machinery. The main objective of this study was to determine the impact of intensive disc harrowing (2, ...

Autor: Suárez Salazar, Juan Carlos Polanía, José Contreras Bastidas, Amara Tatiana Rodríguez Suarez, Leonardo Machado Cuellar, Leidy Ordoñez Espinosa, Claudia Mercedes Beebe, Stephen E. Rao, Idupulapati M.

The common bean is the most important legume for human consumption and is grown in areas under conditions of varied rainfall and temperature that limit its yield. The objective of the present study was to identify genotypic differences in adaptation of 91 bean genotypes to high temperature under ...

Root traits and their potential links to plant ideotypes to improve drought resistance in common bean

Autor: Polanía Perdomo, José A. Poschenrieder, Charlotte Rao, Idupulapati M. Beebe, Stephen E.

Drought stress limits growth and yield of crops, particularly under smallholder production systems with minimal use of inputs and edaphic limitations such as nitrogen (N) deficiency. The development of genotypes adapted to these conditions through genetic improvement is an important strategy to a...
