    A Research on the Determination of Sowing Performance of Pneumatic Precision Drill for Cereals Sowing
    (Univ Namik Kemal, 2009) Bayhan, Y.; Kayisoglu, B.; Ulger, P.; Akdemir, B.
    In this research, sowing rate and seed distribution of furrow openers of pneumatic seed drills were determined. In addition, sowing rates given in the machine catalogue were compared with test results. Coefficient of variation of the seed distribution of the furrow openers were less than that 4% given in the literature as maximum value for evaluating of seed drills. Amount of distributed seed from the furrow openers varied between 3% and 12%. Test results of sowing rates were less than that the catalogue value of sowing machine but differences were not significant statistically.
