This paper presents the data obtained from on-farm experiments on tillage, variety, weed control, and fertilizer in the irrigated areas of Mardan, Peshawar, and Swat Districts of NWFP. More emphasis is given to Mardan ...

In sub-Saharan Africa, greater use of mineral fertilizers is crucial to increasing food production and slowing the rate of environmental degradation. Regional growth rates in fertilizer consumption have never been particularly ...

This study makes use of data on wheat production in the Punjab of Pakistan from 1979 to 1985 to 1) examine patterns of varietal diversity in farmers' fields both at the regional and district levels and 2) identify how and ...

During the 1989-90 and 1990-91 cropping seasons, researchers from CIMMYT and the Evaluation Units of the Malawian Ministry of Agriculture (MOA) collected data to profile farmers' adoption behavior and varietal choices, and ...

This paper profiles farmers' adoption behavior and varietal choices with respect to local and improved maize technologies (variety, fertilizer application, and other agronomic practices) in three agroeconomic zones of ...

Sources of yield growth in wheat are investigated based on a stylized framework of technical change. Evidence suggests that the relative contribution of input intensification to yield growth has diminished in recent years ...

This paper synthesizes the evidence on cereal crop poductivity in developing countries over the past 30 years and looks at future prospects for productivity in growth. For more than three decades we have witnessed the ...

During 1987, a diagnostic survery was conducted in the higher-altitude farming systems of Swat. This followed a field-specific crop-cut survey of maize fields in the same farming systems in 1985. These surveys were designed ...

This publication, through its focus on maize production in drought stressed areas of developing countries, explores economic, research, and policy issues related to maize agriculture in marginal areas of the developing ...
