Effect of Spatial distribution of nitrogen element on wheat crop performance based on yield monitoring system

Abstract: A Steam roller in laboratory scale was designed and built in order to determine parameters on quality and quantity of processed barley. To evaluate rollers performance a series of experiment using split factorial design was conducted. Factors in the experiment design included rollers speed (250, 300 and 350 rpm), rollers gap (0.8 and 1.3 mm) and steaming duration (9, 12, 15 and 20 minutes) with three replications. A local barley variety was used for the experiments. Rollers were adjusted on speed and gap spacing factors first and samples were steamed at four above mentioned levels. Processing index (PI) and particle size analysis was performed using a sieve shaker based on ASAE standards S424.1 after experiments were done passing samples through the rollers. Result of experiments indicated that rollers rotational speed had no significant effect on processing index as well as on particles weight distribution. However, roller gap had a significant effect at one percent probability level. Also, steam duration had a positive effect on processing index as well as on particles weight distribution. Also, mean comparisons for steam duration indicated that no significant difference exists for 9, 12and 15 minutes periods for grain particles larger than 2.38 mm, but for particles smaller than that size and processing index a difference exists. Moreover, the least amount of fine particles can be obtained with 20 minutes steam duration.
