bases irrigadas da região Nordeste. Com a crescente adoção de tecnologias a região transformouse no principal pólo frutícola exportador do Nordeste. O objetivo do trabalho foi analisar o desenvolvimento das exportações da manga no pólo, no período de 1990 a 2002. Fez-se também uma...

O Programa do Milho Híbrido criado pelo governo do Estado do Ceará é executado pela Secretaria de Desenvolvimento Rural desde o ano de 1999 até o presente momento, tem revelado um crescimento médio de 60% ao ano em sementes distribuídas. O objetivo geral deste estudo é analisar o programa...

A orizicultura é um dos segmentos mais promissores deste importante setor da economia varzealegrense, que é a agricultura. O município de Várzea Alegre / CE não dispõe de dados concretos sobre as características socioeconômicas e a predominância tecnológica, referente à produção de...

Az ammónia vízben készségesen oldódó gáz. Kémhatása bázikus, ezért semleges oldatokban ammónium ion formában van jelen, ami alacsony koncentrációban a növények preferenciális nitrogénforrása. Mivel az ammónia az élő növényi sejtekben folyamatosan képződik különböző...

Risk is pervasive in developing country agriculture, and risk preferences are though to impact seed and technology choice. Empirical research on risk preferences and technology adoption typically only consider the risk preferences of a single household member. In this paper experimental...

The study examines the determinants of improved agricultural technologies adoption in Uganda, using a nationally representative panel data set of 1,600 farming households, collected by the Ugandan Bureau of Statistics in 2005/6 and 2009/10. Two agricultural technologies—improved seeds and...

The rice industry in New South Wales, Australia, has benefited from the international flow of germplasm, as have other industries. The aim in this paper is to identify those international flows, and to value their contributions to the industry. Analysis is made of the origins and pedigrees of...

Technical efficiency of wheat farms in eastern England is measured through the estimation of a stochastic frontier production function using panel data for the 1993-1997 crop years. Variations in the technical efficiency index across production units are explained through a number of managerial...

The Iranian government encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. In this paper, using a Cobb-Douglas frontier production function, a simple relationship between a fatm-level output-based technical efficiency measure...

The paper investigates the linkages between technological change and production risk, with an application to corn. The effects of technology on risk exposure are analyzed. We define technological progress to be risk-increasing (risk-decreasing) if it increases (decreases) the relative risk...
