POWER REQUIREMENT FOR SOWING PATTERNS ON TWO FALLOW LANDS UNDER WHEAT PRODUCTION

Abstract

An experiment related to wheat cultivation was conducted at south of Sulaimani province, Kurdistan regionIraq during autumn in 2016-2017. Completely Randomized Block Design was applied with split-split plot arrangement, and the experiment was conducted on two fallow lands, the first land was plowed in the spring and the other remained unplowed, two different sowing modes with rotary seed broadcaster were used, namely conventional and overlapped prose lines, and two similar sets of tillage systems were chosen for the study. The averages were compared by using Duncan’s test. The coefficients of variance (CV) for overlapped and conventional seed spreading were 9.2% and 48.4%, respectively. The spring-plowed fallow land proved to obtain significantly different values compared to the unplowed land, which were higher by 51.9%, 48.5%, 47.1%, 26.9%, 31.6%, 6.7% and 30.1% for fuel consumption, draft, power losses due to slippage, working time, energy utilization, wheat yield and total cost, respectively. The average results for overlapped seed broadcasting were higher than those of the conventional manner by: 0.8%, 0.3% 1%, 0%, 3.3%, 6.7% and 14.5%. The lowest values were resulted from applying: MB plus seed distributor plus MB, while, the maximum yield was given by applying: cultivator plus seed distributor plus cultivator.
