This study aims to define the role of zero tillage (ZT) in economic return for the lentils in the regions of Al-Qamishli and Al-Malikiyah (Al-Hasakah governorate). All farmers who followed ZT system in these regions has been selected. Sample size amounted to 200 randomly selected farmers, of which 100 follow ZT system, and the other 100 follow traditional cultivation. The economic analysis depended on estimating the average production costs, and economic returns for growing seasons 2013/2014 and 2014/2015. The results showed that the production cost in ZT is less than the TC by 12%, estimated to 56024, 63982 SYP/ha respectively. The net profit of ZT was about 391986 SYP/ha on average, with 7958 SYP/ha greater than TC.  Moreover the average cost ZT compared to ZT has been reduced by 19.8%, estimated to 30 and 37 SYP/kg, respectively. The analysis showed that the ZT reduce the amount of fuel consumption, working hours, seeding rate and total cost by 67%, 56 %, 44%, 32%, respectively. While the yield has increased by 9%.  This study revealed that ZT achieved an economic return higher than TC by 12 %.

Keywords: Zero tillage (ZT), Traditional cultivation (TC), Production costs, Economic return, Rain-fed lentils.

This research was conducted at the General commission for Scientific and Agricultural Research (GCSAR), AL Qamishli Scientific Agricultural Research Center, AL Qamishli , Syria. in the first establishment zone, according to the split plot design, where agricultural system (zero tillage, and traditional tillage) represented the main treatments and fertilizations the split treatments, with three replications. Four levels of nitrogen fertilizer (N0 , N1 100 kg/ha , N2 150 kg/ha , and N3 200 kg/ha) as Urea 46%, and three levels of phosphoric fertilizers (P0 , P1 100 kg/ha, and P2 150 kg/ha) were used. Results of the three seasons 2008- 2011 showed that zero tillage treatments significantly over yielded traditional ones by 8-20 % , that can be attributed to different fertilization levels of N and P in addition to rain. Results also clarified that increasing of N fertilization at (P0), has given significant increase in production on direct proportion with the increase of nitrogen fertilizing level (N1, N2, N3) and reached in comparison with the control (110, 178, 217 kg/ha) in the traditional tillage, but in zero tillage the productivity at the tow levels (N1, N2) increased by (118-147 kg/ha) respectively. The increase has reduced at the level N3 to(113 kg/ha), but at (P1) fertilizing level of zero tillage the yield increase of (N1) reached (336) kg/ha, which significantly over yielded the (N1,N2) by (313, 247 kg/ha). While under traditional tillage the highest increase reached (313 kg/ha) under N2 and the yield decreased 147 kg/ha under N3.  At (P2) level and (N0) level the increase in yield under zero tillage was(147 kg/ha),to become at N1 level up to (216 kg/ha) and to reach at (N2) to (376 kg/ha). Consequently, zero tillage significantly over yielded the traditional tillage. We recommend using zero tillage with (N2, P2) fertilization levels.
