the aim of this research was to investigate performance of two combined plows compared to conventional plow. the experiments were conducted in a loamy soil texture with moisture content of 16-18% in karaj region of iran. combination of moldboard+chisel plow and disk plow+chisel plow were compared with conventional moldboard plow as three treatments. data was statistically analyzed using rcbd in...

dryland winter wheat (triticum sativum l.) generally grown in rotation with fallow or chickpea (cicer arietinum l.) constitutes a major crop in the west region of iran. information is limited on the success of more intensive dryland cropping systems while applying conservation tillage management. an experiment was conducted to determine the effect of five tillage systems on soil physical proper...

using the cropping operations program can significantly save fuel consumption and energy efficiency. prediction of the accurate amount of fuel requirements for tillage operation of the soil is difficult. changes in humidity, soil type and tillage depth directly affects on the amount of fuel consumption. bulk density of agricultural soils depends on tillage methods, the value of organic matter, ...

A GLEAMS (ver. 2.10) model was calibrated and validated using three years (1990–1992) of field–measured data to simulate tillage effects on nitrate–nitrogen (NO3–N) and herbicide losses with subsurface drain “tile” water beneath a continuous corn production system. The model was calibrated for chisel plow systems using 1991 field data and was validated against field data of two years (1990 and ...

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...

Wilhelm, W.W., Hinze, M.R. and Gardner, C.O., 1991. Maize hybrid response to tillage under irrigated and dryland conditions. Field Crops Res., 26: 57-66. The popularity of reduced-tillage cropping systems has emphasized the need to determine if maize (Zea mays L.) developed under conventional tillage systems (moldboard plow, disk, and harrow) is readily adaptable to conservation production syst...

Post-Conservation Reserve Program (CRP) land may provide an excellent opportunity to satisfy certified organic crop production requirements. However, conversion of CRP or long-term pastureland to certified organic production will require tillage because the use of herbicides is prohibited in organic production. Our objectives were to evaluate stand establishment, weed competition, yield, and gr...
