| Abstract | ||
| The experiment was conducted to evaluate the performance indicators for NewHolland Tractor TM 140 and Massey Ferguson TSB 555 precision planter, eight lines, in Sudan. Air pressure system with two levels included 2.0 and 2.5 PSI represented main plots. Planter speed with three levels included 6.36,8.7 and 10.14 km/h were sub plots.A split plot arrangement with (RCBD) three replications was used. Effective field capacities, field efficiency, amount of seeds per meter and fuel consumption werestudied. Ag leader control was installed in the NewHolland tractor to control and measure the indicators of the performance for both planter and tractor. The results showed that increasing of air pressure system from 2 to 2.5 PSI increased the amount of seeds from 8.5 to 8.8 seeds per meter and increase fuel consumption from 13.68 to 14.37 lit/hand increase slippage percentage from 8.21 to 9.61% but decreased effective field capacity from 4.74 to 4.66 hec/hand also decrease field efficiency from 92.00 to 90.34 %. The increasing of practical velocity from 6.36 to 8.7then to 10.14 increased effective field capacity from 3.66 to 4.86 to 5.67hec/h,fuel consumption from 12.79 to 13.67 to 15.62 lit/hand slippage percentage from 5.50 to 7.70 then to 13.56 %, but decrease field efficiency from 94.46 to 92.28 then to 86.42 %. Best performance for each planter and tractor at 2 PSI and practical velocity 8.77 km/hr where the average of seeds 9.2 seeds/meter, field efficiency 93.08%, fuel consumption 13.14 lit/h and slippage percentage 6.9%.It can be recommended for this speed and pressure when working in this or similar conditions and the importance of using modern technologies in agriculture fields and make training courses for farmers about it. | ||
