Abstract:
The experiment was carried out at the farm of the Faculty of Agriculture and Veterinary
Medicine, Thamar University, Dhamar Governorate to study the performance field evaluation of
wheat seeder machine (Gaspardo No 0709). Three factors were selected for this research they are
forward speed (2.02-2.05, 3.7- 3.80 and 3.91- 4.05km/h), three weight of grain (2, 3 and 4 kg)
and tow sowing rate (20 and 40 kg/ha).The experimental data were analyzed using analysis of
variance (ANOVA). The means were compared with LSD at 5% level significance for all study
parameters. This analysis was performed by Statistical Analysis SAS program. The results
showed that the largest discharge rates were found to be 168.03, 108.54 and 111.25 g for the
discharge opening 40 kg, speed 3.91-4.05 km / h and seed quantity 2 kg, respectively. The
largest mean number of plants / 1 meter length was 54.778, 49.6459 and 52,458 for the discharge
opening 40 kg, speed 3.91 - 4.05 km / h and seed quantity 2 kg, respectively. The largest mean of
plant density (plant / m2
) was 219.11, 197.00 and 209.83 plants / square meter for discharge
opening 40 kg, speed 3.91 - 4.05 km / h and seed quantity 2 kg, respectively. The results showed
that the discharge opening (40 kg / ha x 6 boxes) was significantly superior by giving it the
highest rate of discharge, as the highest values were attained for the two studied traits (number of
plants in 1 meter length and the value of plant density) compared to the discharge opening 20 kg
/ ha x 6 boxes). While the difference in speed, did not have a significant effect on the rate of seed
discharge for all studied traits. Also, the quantity of seeds (2) kg achieved the highest rate of
discharge, and the highest values at the two studied traits compared to the quantities (3 and 4) kg.
The obtained results recommended using discharge opening 40 kg, speed 3.91 - 4.05 km / h and
the quantity of seeds (2) kg. |
