Soil quality as affected by tillage-residue management in a wheat-maize irrigated bed planting system
There is a clear need to develop conservation agriculture technologies appropriate for surface irrigated conditions, and the adoption by small-scale farmers. The objective of this paper is to evaluate the effect on soil ...
Soil water content, maize yield and its stability as affected by tillage and crop residue management in rainfed semi-arid highlands
Rainfed crop management systems need to be optimized to provide more resilient options to cope with projected climatic scenarios forecasting a decrease in mean precipitation and more frequent extreme drought periods in ...
Impact of Mexican germplasm on Brazilian wheat cropping: an ex-post economic analysis
This paper reviews and analyzes economic returns to wheat research in Brazil's main wheat-producing regions in Rio Grande do SuI and Paranci. Between 1975 and 1991, the area planted to wheat in Brazil increased significantly ...
Indirect selection for grain yield in spring bread wheat in diverse nurseries worldwide using parameters locally determined in north-west Mexico
The relationships of normalized water index three (NWI-3) and canopy temperature (CT) with grain yield in north-west Mexico were determined in a set of wheat lines planted in multi-location yield trials. Advanced wheat ...
Effects of conservation tillage on water supply and rainfed maize production in semiarid zones of west-central Mexico
This study analyzes the potential of conservation tillage (CT) for improving maize productivity under a range of soil and rainfall conditions in a semiarid zone of West-Central Mexico, evaluating the consequences of tillage ...
El potencial de la labranza de conservación en la mixteca Oaxaqueña
Se llevó a cabo en marzo de 1992 un sondeo en la Mixteca Oaxaqueña, región donde existen problemas fuertes de erosión y sequía que reducen severamente los rendimientos de maíz y de trigo. Dado que las tecnologías de la ...
Characterization of Mexican Creole wheat landraces in relation to morphological characteristics and HMW glutenin subunit composition
One hundred lines derived from 14 wheat landraces collected in Mexico were characterized in relation to spike and grain morphology and HMW-glutenin subunit composition. Up to seven botanical varieties were identified among ...
