Prognóstico dos rendimentos qualitativos do milho na agricultura de sequeiro em Moçambique

Abstract

This work presents a prognosis of qualitative yields of corn in rainfed agriculture in Mozambique. To achieve the objectives, the period from 1974-2003 was chosen and data manipulation was performed using two statistical packages (Excel and AgroMetShell) In the south, the beginning of the rainy season varies between the third decade of October and the third decade of November. The end of the rainy season varies between the third decade of February and the second decade of April. In the North, the beginning of the rainy season varies between the second decade of October and the first decade of December. The end of the rainy season varies between the third decade of March and the third decade of April. There is a close relationship between the characteristics of the rainy season represented by the amount and distribution of precipitation and the yields of maize in Mozambique. Precipitation during the agricultural season, and in general, badly destroyed mainly in the south, where the expected yields are low. However, in the Center and North, rainfall is not as badly destroyed as it is in the South, for which results show average expected yields. It is proposed with this work to develop the liner regression model, to determine current evapotranspiration, to continue with the study used more meteorological stations with better representativeness and in agro-ecological zones.
