Study on the efficiency of seeder performance in no-tillage farming system and its impact on selected technical and physical performance indicators and wheat yield

Eield experiment was conducted in one of the fields in Baghdad Governorate during the 2021-2022 agricultural season in loamy soil to investigate the feasibility of using no-tillage farming systems for wheat cultivation and their impact on plant growth and yield.The experiment employed a German-made NEWHOLLAND Tractor 80-66S with machinery units,The study examined three factors.Three speeds were tested 4.23, 6.54, and 8.37 km/h.Two seed rates were used 100 kg/ha and 140 kg/ha.Three configurations were evaluated: Osduman seeder alone, Osduman seeder with soil servicing tools, Broadcaster seeds with soil servicing tools.Performance indicators studied included fuel consumption rate, field efficiency, drawbar power, soil moisture content, and biological yield.The least significant difference (LSD) test at a 0.05 significance level was used to compare treatment means.The highest speed 8.37 km/h, at a seed rate of 100 kg/ha and with the Osduman seeder treatment Z, recorded the lowest fuel consumption rate of 4.26 L/ha and the highest field efficiency of 73.42%.At the same speed and seeder configuration treatment Z but with a seed rate of 140 kg/ha, the highest biological yield was achieved 7067 kg/ ha.The lowest speed 4.23 km/h, at a seed rate of 100 kg/ha and with the Osduman seeder, recorded the highest soil moisture content 0.247%.At the same speed and seed rate but with the Osduman seeder combined with soil servicing tools treatment Zt, the lowest draft power, was recorded 1.88 kW.
