Abstract The investigation was conducted in the 2019–2020 agricultural season Al-Thaghr area, north of Basrah Governorate, Iraq (latitude 31.145288N and longitude 47.431334E), clay soil. Two factors were used investigation. first factor three tillage systems (heavy by mouldboard plow, low chisel no-till system). second concentrations biocide Trichozon (4 g m -2 , 2 without adding pesticide). ex...

Syringopais temperatella Led. (Lep., Scythrididae) is a serious threat of barley and wheat in Jordan as it causes great loss crop. There growing interest the development innovative control strategies aiming to minimize environmental impact pest management improve safety agro-food chain. However, little attention has been paid on use cultural methods against pest, accordingly, this study aimed a...

optimum working life of tractor and farm machinery employed in potato production in hamadan province was assessed through data envelopment analysis. an input oriented model was applied to determine the optimized machinery system. in this model inputs were the lifetime of tractor as well as seven involved machines including moldboard plow, potato planter, chemical fertilizer spreader, tractor mo...

drafts of major primary tillage implements were measured in a clay loam soil using a tension loadcell. implements consisted of a moldboard, a disk and a chisel plow each equipped with one tillage unit. a photoelectric speed sensor was used for actual forward speed measurements. during the study, the effects of forward speed and tillage depth on draft requirements were investigated. a general re...

This research focused on rill formation, rill density, and associated flow velocity distribution in rills at the field level and with different tillage treatments in the inland Pacific Northwest. The study was conducted by applying flow at three different rates under winter conditions, which provides the greatest potential for rill formation. The following tillage treatments were tested: chisel...
