one of the basic adjustments in application of agricultural implements, particularly tillage tools, is their work in a leveled state while in operation. throughout the ongoing research, and by application of electronic and hydraulic circuits, an intelligent system was designed, developed and evaluated. the device is expected to perform the plow longitudinal as well as lateral adjustments at the...

A two-year field study was conducted to investigate the performance of a lightweight trash-board moldboard plow (with and without a trash-board), as influenced by stubble height and water content. Both fields were measured for the performance of a trash-board moldboard plow when used during the optimization of the plowing depth, the water content, and the reaction forces. The results showed tha...

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...

Soil C change and CO2 emission due to different tillage systems need to be evaluated to encourage the adoption of conservation practices to sustain soil productivity and protect the environment. We hypothesize that soil C storage and CO2 emission respond to conservation tillage differently from conventional tillage because of their differential effects on soil properties. This study was conduct...

field capacity, fuel consumption and drive wheel slippage in massey ferguson (mf399) tractor with standard and liquid ballasted (630 kg) axle load and at 4wd mode was evaluated and compared. the tests were conducted at the experimental station, college of agriculture, shiraz university, in a field with clay loam soil at average moisture content of 18% d.b. the experiment was of a randomized com...

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...

Soil loss from dryland farms on the Columbia Plateau in Oregon and Washington (USA) results primarily from rain falling on frozen, cultivated soil. Soils are most susceptible to erosion when moldboard plowed, summer-fallowed, repeatedly rodweeded or cultivated, and fall planted to winter-wheat. These tillage practices are used because they help control weed and disease infestations and consiste...
