Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains... |

As cultivares atualmente plantadas na região apresentam porte alto, principalmente quando cultivadas em áreas de matas recém desbravadas e espaçamento reduzido, o que favorece o acamamento. um dos principais problemas da orizicultura acreana. Os trabalhos de introdução de material genético para as condições do Estado do Acre, não tem apresentado resultados satisfatórios, possivelmente, pelo fato desse material ter sido desenvolvido em região de clima, solo e cultivo, diferentes das condições desse Estado. Partindo de 30 cultivares provenientes do Centro de Pesquisa Agropecuária do Trópico Úmido (CPATU), foi conduzido um ensaio no campo experimental da EMBRAPA/UEPAE-Rio Branco, no ano agrícola 19801/81, em área de terra firme, de Latossolo Amarelo, textura... |
