| Abstract | ||
| The experiment was conducted to study the effect of two plows (Mold board plow , disk plow) under three depth levels 12 , 15 , 18 cm and tractor speeds 2.001 , 3.814 , 4.522 km/h in some technical indicators and sunflower yield were used in study slippage percentage ,fuel consumption , field efficiency , roots depth , diameter sunflower , capacity of root , number of seed in head and sunflower . The result showed that the mold board plow was significantly superior compared disk plow in all studied properties . The result showed that the increase depth of plowing from 12 to 15 and to 18 cm caused an increase in slippage percentage , fuel consumption and decrease Field efficiency and all yield properties . Increase the tractors speed from 2.001 to 3.814 and 4.522 km / hr caused an increase in slippage percentage , and decrease fuel consumption , field efficiency and all yield properties head . | ||
