Abstract


Direct combine harvesting of crops helps in solving the problem of
labor shortage during harvest period, timely harvest and obtaining good grain quality. A study was conducted in the mechanized rain fed schemes in
Gedarif State eastern Sudan to evaluate the performance of different combine harvester makes, to quantify harvesting losses and to estimate the value of the losses for direct harvesting of sorghum. Three combine harvester makes were assessed, namely; New Holland, Claas and Massey Ferguson. The data was collected from 46 combine harvesters during three harvesting seasons (2014, 2015and 2016). The exact number of each combine harvester make was 21, 9 and 16 for New Holland, Claas and Massey Ferguson, respectively. The collected data included machine parameters, harvesting losses and economic data. Results showed that the average forward speed, work rate, field efficiency and fuel consumption, was 5.1 km/hr, 2.2 ha/hr, 86% and 7.4 l/ha, respectively. The three harvesters produced similar seed quality in terms of sound seeds, cracked seeds and impurities. The pre-harvest loss was significantly (P ≤ 0.01) the highest among the other loss types. Irrespective to harvester make, the header loss was significantly (P ≤ 0.01) the highest among machine loss types. No significant differences were noted between combine harvester makes in threshing and machine losses. The total harvesting, machine and collectable losses were 25.1 %, 10% and 19.4 %, respectively. The average value of the pre-harvest loss, machine loss, total loss and collectable loss was 432.4 SDG/ha, 304.4 SDG/ha, 736.8 SDG/ha and 188.9 SDG/ha, respectively. In conclusion, the performance of the three combine harvesters was technically satisfactory, the machine loss was reasonable and collecting the remaining heads manually after harvest was
profitable
