THE EFFECT OF THRESHER SPEEDS ON SEED LOSS: RETAINING WHEAT SEED QUALITY
Main Article Content
บทคัดย่อ
being concerned with retaining wheat seed quality, both the use of a wheat thresher and beating with bamboo sticks were examined for comparative seed loss. The testing of the thresher was done using 5 different drum speeds: 1,000,900,800, and 700 rpm. Results show that neither fast nor slow threshing affect the quantity of seed produced. Within total losses, the main loss occurred as unthreshed seed in plant residue. Discarded seed, the percentage of broken seed and threshing time did not vary between treatments. Loss was at a minimum after beating with bamboo sticks. Tin cans proved to be good containers. Seed quality after 7 months storage was satisfactory
