The impact of conservation tillage on the productivity and stability of maize cropping systems: a case study in Western Mexico
(CIMMYT, 2001)
This paper examines the economics of introducing conservation tillage into existing maize cropping systems in the state of Jalisco, in the western part of Mexico. A stochastic cost-benefit analysis (SCBA) of introducing ...
Book
Conservation agriculture and soil carbon sequestration: between myth and farmer reality
(CIMMYT, 2009)
Human efforts to produce ever-greater amounts of food leave their mark on the environment. Persistent use of conventional farming practices based on extensive tillage, especially when combined with removal or in situ burning ...
Book
The adoption of bed planting of wheat in the Yaqui Valley, Sonora, Mexico
(CIMMYT, 1998)
This report presents results of the analysis of data from a survey conducted during the fall-winter 1993/94 crop cycle in the Yaqui Valley of northwestern Mexico. It describes the agronomic characters of wheat producers ...

Farmer assessment of velvetbean as a green manure in Veracruz, Mexico: experimentation and expected profits
(CIMMYT, 1996)
This study explores factors associated with farmers' decision to experiment with velvetbean (Mucuna spp.), a green manure, as a maize intercrop in three villages of Veracruz, Mexico. To asses whether velvetbean might be ...
Book
Are productivity enhancing, resource conserving technologies a viable "Win-win" approach in the tropics? The case of conservation tillage in Mexico
(CIMMYT, 1997)
This paper summarizes factors affecting the agricultural and environmental potential of conservation tillage in maize-based farming systems in Mexico. The author begins by describing some of the implications of soil ...
Handbook
Yield and yield components: a practical guide for comparing crop management practices
(CIMMYT, 2013)
Agronomic practices are evaluated using yield data so it is essential the yield information is representative and reliable. The purpose of this manual is to explain in practical terms how to obtain such data. The manual ...
Handbook
Soil aggregate stability by wet sieving: a practical guide for comparing crop management practices
(CIMMYT, 2013)
Soils are subjected to spatial and temporal alterations of aggregates and pores caused by natural (pedogenesis) and anthropogenic (management) factors (Lal and Shukla, 2004). In fact, soil aggregate distribution is a static ...
Handbook
Soil aggregate distribution by dry sieving: a practical guide for comparing crop management practices
(CIMMYT, 2013)
From a physical perspective, the soil matrix is generally conceptualized as being constituted by soil aggregates (filled spaces) or secondary soil units, and pores (empty spaces) (Soil Science Society of America, 1997; Lal ...
Handbook
Cracking: a practical guide for comparing crop management practices
(CIMMYT, 2013)
Soil cracking can occur when wet or moist soil dries and is common in soils with a high swell-shrink clay content. Evaporation of soil pore water leads to a build-up of negative pressure which results in a reduction of ...
Handbook
Penetration resistance: a practical guide for comparing crop management practices
(CIMMYT, 2013)
Penetration resistance is an indicator for the level of compaction of the soil. Compaction limits root growth and the availability of air and water to the roots (Herrick and Jones, 2002; Lampurlanés and Cantero-Martínez, ...
