A study some rice growth properties under impact practical speed and tillage depth

الملخص EN

The effect of practical speed and tillage depth was studied on some mechanical properties for tillage machine ( moldboard plow type ) and soil physical properties on Rice Jasmine variety at two practical speed levels of 2.

681Km.

hr-1and 3.

562 Km.

hr-1 and three levels of tillage depth of (10, 14and 22cm).

The experiments were carried out in a factorial experiment under randomized complete block design with three replications.

The results showed that the practical speed of 2.

681 Km.

hr-1is significantly better than the practical speed levels of 3.

563 Km.

hr-1 as well as tillage depth 10cm was significantly superior to the other two tillage depth 14 and 22 cm in all studied parameters except fuel consumption and field efficiency.

The results showed fuel consumption of 9.

762 and 8.

599 L.

ha-1, field efficiency of 76.

407 and 77.

287 %, slippage percentage of 8.

796 and 8.

002%, germination percentage 95 and 98%, plant height 74.

9 and 75.

5 cm, the plant branches number 4 and 6 branch/plant, 100-grain weight 19.

18and 19.

58 g and grain yield 3.

200 and 3.

273t.

ha-1 for practical speed levels of 2.

861 Km.

hr-1 and tillage depth 10 cm, respectively
