Avaliação de factores intervenientes na lavoura com tracção animal na Macia

Abstract

The present work has as main objective: to evaluate the intervening factors in the farming with animal traction in Macia, as well as its quantification. This work was carried out in the villages of Magul and Manzir, in the district of Macia in Gaza Province. The data were collected in “serra” (friable soil) and “low” (heavy soil) soils in the villages of Magul and Manzir between the months of August and October 2001. The treatments consisted mainly of tests with plows. complete and incomplete moldboards (without tuning and adjustment accessories). Three joints were used, two of which had characteristics closer to those of draft animals in the region, and the other was larger than the typical size of the region. Data analysis was performed using the Mstat program performing test 1 with a significance level of 5% and also comparing the results with some literature data. Thus, from the work carried out and with the methodology outlined, the results suggest that the efficiency of the crop in both types of soils was not affected by the removal of accessories from the implements. It was also found that there was a relative excess of power of around 400 Watts to plow the soils in the “low” compared to those in the “serra”. It is recommended that more studies of this kind be carried out in other regions of Mozambique in order to have a real standard of data for the specific climatic, environmental and social conditions of each region
