Adoption, Management, and Impact of Hybrid Maize Seed in India AgEcon
Singh, R.P.; Morris, Michael L..
This paper presents results of a 1995 survey of 864 maize-growing households in six states that account for more than 70% of India's maize area: Andhra Pradesh, Bihar, Karnataka, Madhya Pradesh, Rajasthan, and Uttar Pradesh. The current adoption of improved open-pollinated maize varieties (OPVs) and hybrids is quantified, the relationship between adoption of improved germplasm and use of improved crop management practices is examined, the economic impacts of adoption are estimated, farmers' seed procurement and management practices are described, and implications for maize research and development policy are discussed. On the whole, the survey results confirm that India's national maize seed industry is expanding rapidly. Since seed policy reforms were...

FACTORS EXPLAINING THE DIFFUSION OF HYBRID MAIZE: EVIDENCE FROM LATIN AMERICA AND THE CARIBBEAN IN SUPPORT OF THE LIFE CYCLE THEORY OF SEED INDUSTRY DEVELOPMENT AgEcon
Kosarek, Jennifer; Morris, Michael L.; Garcia, Philip.
Factors affecting the diffusion of hybrid maize are explored using a unique data set from 18 countries in Latin America and the Caribbean. Our findings not only validate the conventional profitability-based explanations of farmer adoption behavior, but also confirm the importance of supply-side factors, providing empirical support for the life cycle theory of seed industry development.

HOW DOES GENDER AFFECT THE ADOPTION OF AGRICULTURAL INNOVATIONS? THE CASE OF IMPROVED MAIZE TECHNOLOGY IN GHANA AgEcon
Morris, Michael L.; Doss, Cheryl R..
Why do men and women adopt agricultural technologies at different rates? Evidence from Ghana suggests that gender-linked differences in the adoption of modern maize varieties and chemical fertilizer are not attributable to inherent characteristics of the technologies themselves but instead result from gender-linked differences in access to key inputs.

IMPACTS OF INTERNATIONAL MAIZE BREEDING RESEARCH IN DEVELOPING COUNTRIES, 1966-98 AgEcon
Morris, Michael L..
This report, which updates and extends the findings of an earlier CIMMYT study published in 1994, documents the impacts of international maize breeding research in the developing world. Covering the period 1966-98, the report reviews public and private investment in maize breeding research, describes the products of public and private maize breeding programs, estimates farm level adoption of modern varieties (MVs), and estimates the gross value of additional grain production attributable to international breeding efforts. Although private companies have greatly increased their investment in maize breeding research in recent years, public maize breeding programs still play an important role, especially in breeding for subsistence-oriented farmers. Seed...

PRACTICAL CHALLENGES TO ESTIMATING THE BENEFITS OF AGRICULTURAL R&D: THE CASE OF PLANT BREEDING RESEARCH AgEcon
Heisey, Paul W.; Morris, Michael L..
Interest in the economics of plant breeding first emerged during the late 1960s and early 1970s following the well-known green revolutions in wheat and rice. Since that time, few branches of agricultural research have been subjected to as much scrutiny as plant breeding. Impacts assessment studies consistently conclude that the economic benefits generated by successful plant breeding programs are large, positive, and widely distributed. Case studies repeatedly find that investment in crop genetic improvement generates attractive rates of return compared to alternative investment opportunities. Similarly, case studies consistently show that the welfare benefits resulting from the adoption of modern varieties (MVs) are broadly shared by producers and...

Promoting Sustainable Pro-Poor Growth in Rwandan Agriculture: What are the Policy Options? AgEcon
Morris, Michael L.; Drake, Liz; Ezemenari, Kene; Diao, Xinshen.
In 2000, as part of its strategy for growth and poverty reduction, the Government of Rwanda set a goal to increase per capita income from US$230 to US$900 and halve the incidence of poverty by 2020. Two years after those targets were established Rwanda's first Poverty Reduction Strategy Paper (PRSP) projected that GDP growth in the range of 6 to 7 percent would be needed over the long term for those targets to be realized. The principal sources of growth in the short to medium term were to be the agriculture and manufacturing sectors, with agricultural projected to start at 5.2 percent and accelerate over the period due to productivity improvements. Manufacturing growth was projected to rise sharply to 11.5 percent, based on the expansion of manufacturing...

THE PROGRAMMABLE CALCULATOR AS A TOOL FOR PRICE ANALYSIS IN DEVELOPING COUNTRIES AgEcon
Morris, Michael L..
The objective of this study is to investigate the appropriateness of hand-held programmable calculators as a research tool for economists working on price policy issues in LDC's. The emphasis is on the use of programmable not for purposes of sophisticated analysis of large data sets, but rather for preliminary analysis of the sorts of data economists typically work with in the field. A few authors have attempted to develop and test research-oriented programs relating to particular fields of inquiry, but such efforts are not yet widespread. This study attempts to expand the scope of these preliminary efforts by exploring the possibility that programmable calculators might be adopted for use by the research economist working on price analysis issues. If...
