Ensuring the use of sustainable crop management strategies by small wheat farmers in the 21st century
(CIMMYT, 1998)
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 ...

Adaptation of wheat to the canopy environment: physiological evidence that selection for vigor or random selection may reduce the frequency of high-yielding genotypes
(CIMMYT, 1993)
Increasing the potential yield of wheat is a major thrust of CIMMYT's Wheat Program. Farmer's wheat yields are linearly related to the yield potential of new varieties. At the same time, breeders should ideally be able to ...

Intercropping cereals with N-fixing legume species: a method for conserving soil resources in low-input systems
(CIMMYT, 1993)
The natural resources of the developing world are becoming increasingly threatened as the agricultural sector intensifies. A major resource being lost is the topsoil. Low levels of soil organic matter and the incomplete ...

Wheat production and grower practices in the Yaqui Valley, Sonora, Mexico
(CIMMYT, 1992)
Wheat yields in the Yaqui Valley of NW Mexico have appeared to remain stable in the past decade despite the release of new varieties and improved agronomic recommendations. A study was conducted during the winter of 1990/91 ...

Canopy temperatures of wheat: relationships with yield and potential as a technique for early generation selection
(CIMMYT, 1993)
It is shown that, for bread wheat, air-canopy temperature difference correlates significantly with grain yield, especially when measurements are taken later in the day, We discuss the potential of this technique as an early ...

Increasing wheat yields sustainability through agronomic means
(CIMMYT, 1998)
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. ...

Cultivo intercalado de cereales con especies de leguminosas que fijan N: un metodo para conservar los recursos del suelo en sistemas de bajos insumos
(CIMMYT, 1994)
La producción de cereales con pocos insumos y gran eficiencia contribuye a aliviar la pobreza, incrementa los ingresos agrícolas y favorece la conservación del medio ambiente (1os suelos y el agua). Este Informe Especial ...
Book
Applications of raised-bed planting systems to wheat
(CIMMYT, 1997)
Wheat has traditionally been planted in solid stands, especially in irrigated environments and rainfed production systems with moderate to high rainfall. Wheat is usually planted by either drilling closely spaced rows 10-30 ...

Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
(American Phytopathological Society (APS), 1998)
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 ...
