Abstract
A triple-purpose combine implement has been assembled manufactured and in the Department of Agricultural Machines workshop to be used in furrow, fertilization and seed planting. It consists of triple implements included,furrowing and seeding and fertilization. A field experiment was conducted in one of the fields of the Faculty of Agriculture - University of Baghdad in 2013 in silt loam soil in order to assess the efficiency of the locally manufactured combine implement. New Holland TD80 tractor was used with the combined implement as a machinery unit. Six speeds of the tractor were used included; 3.69, 4.23, 5.61, 6.27, 8.33 and 11.17 km/h, which represented the main plots and the depth of furrows included 15, 20 and 25 cm, which represented the subplots were used in this study. Width of furrow, practical productivity, the amount of seed and the distance between the gore and the fuel consumption were measured in this experiment. The experiment was carried out with under the (RCBD) with three replications. Maize crop Class 5018 was planted in the experiment The results can be summarized as fallows; A speed of 6.27 km/h gave the best rate for furrow width (77cm), the best rate for seeds (30.60 Kg/hac) and the best rate of distance between the gore reaching 26 cm. While speed 11.17 km/h outperformed in giving the lowest rate of fuel consumption as it amounted to 5.99 l/h, the rate of the practical productivity was 2.11 hac/h, the best rate of furrow depth at 25 cm, the best rate of furrow width at 76.41, the best distance between gore at 26.17 cm and quantity of seeds reaching 37.04 kg/h and gave furrow depth of 15 cm and a higher rate of the practical productivity amounted to 1.24 hac/h and the lowest rate of fuel consumption amounted to 8.91 l/h.As for the significant of overlap between the speed and furrow depth, it has impacted significantly in all traits. The test the combine implement proved the success to be used in the work of furrow opening at a suitable width and depth for the cultivation of maize, as well as the right amount for seeding and fertilizing and within the distance recommended by the competent agricultural circles of Ministry of Agriculture.
