Increasing wheat yields sustainability through agronomic means
This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. ...
Ensuring the use of sustainable crop management strategies by small wheat farmers in the 21st century
Virtually all current strategies to implement modern, sustainable crop management production practices involve conservation/zero tillage prior to seeding, some form of crop residue retention and management, fertilizer ...
Yield potential progress in short bread wheats in Northwest Mexico
Germplasm from the spring wheat (Triticum aestivum L.) breeding program at the International Center for Improvement of Maize and Wheat (CIMMYT) has had a major impact on the yield of irrigated spring wheats in most developing ...
Genetic progress in wheat yield and nitrogen use efficiency under four nitrogen rates
The adaptation and performance of CIMMYT's bread wheat germplasm (Triticum aestivum L.) under conditions of low N fertility have been questioned because they were developed under medium-high levels of N fertility. The ...
Interpreting genotype X environment interaction in wheat by partial least squares regression
The partial least squares (PLS) regression method relates genotype × environment interaction effects (GEI) as dependent variables (Y) to external environmental (or cultivar) variables as the explanatory variables (X) ...
Applications of raised-bed planting systems to wheat
Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...
CIMMYT's genetic progress in wheat grain quality under four nitrogen rates
Wheat (Triticum aestivum L.) breeders often try to simultaneously improve grain yield and bread-making quality. This study examined changes in CIMMYT's wheat germplasm with respect to grain protein concentration (GPC)- and ...
