Comparison between two manufacture tools for conservation agriclture under rainfed agriclture conditions [electronic resource].

With fact that world population has increased over the years and more food needs to be produced, this will put more pressure on the natural resources. However, conservation agriculture which to achieve acceptable profits from agricultural production and sustain the production of resources has to be used as main aspect for arid land cultivation. Field experiments were carried out during growing season (2012 / 2013) at Ras El-Hekma area, Northwestern Coast of Egypt, to comparison between the two local manufactured machines for cultivation barley under conservation agriculture Systems in rainfed areas. Rainfall is the individual source of water in the area of experiment. The first local manufactured combination unit (a) included suitable unites for tillage, planting and fertilization. While, the other local manufactured machine (b) was suitable for water harvesting and planting. The treatments of the two local equipments were achieved through applying four different forward speeds, i.e., 1.98, 2.70, 3.42 and 4.5 km/h and three different plowing depths, i.e., 10, 15 and 20 cm. Adding Farm Yard manures at level of 10 m3/fed, and 50% of soil surface covering by crop residues (rice straw) were conducted for all treatments. Several parameters were used in comparison for the performance of the two machines, such as some soil and water properties. Results indicated that the lowest value of bulk density was observed with the forward speed of 1.98 km/h and plowing depth of 20 cm, i.e. 1.08 and 1.12g/cm³, for the two machines (a & b), respectively, as compared to that for the other treatments. Increasing plowing depth from 10 cm to 20 cm at the forward speed of 4.5 km/h for the machine (a) and (b) led to decrease bulk density by 17% and 14%, respectively.
