Soil tillage is a critical process in agricultural production. Furthermore, the consumes lot of energy and time to complete soil practices. A disk plow with triple disks was tested one Agriculture Forestry college plantations at University Mosul during season 2013. The research included two moisture contents (10.7 16.2%), three distances between inner face scraper (2, 4, 6 cm). Besides, forward...

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...

Soil N2O emissions from three corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] systems in central Iowa were measured from the spring of 2003 through February 2005. The three managements systems evaluated were full-width tillage (fall chisel plow, spring disk), no-till, and no-till with a rye (Secale cereale L. 'Rymin') winter cover crop. Four replicate plots of each treatment were establishe...

Crop growth models can be useful tools in evaluating the impacts of di€erent tillage systems on the growth and ®nal yield of crops. A tillage model was incorporated into CROPGRO-Soybean and tested for conditions in Ames, IA, USA. Predictions of changes in surface residue, bulk density, hydraulic conductivity, runo€ curve number, and surface albedo were consistent with expected behaviors of thes...

to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...

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...

a one-way moldboard plow turns over soil in only one direction. problems created by this type of tillage in iran include compaction of boundary regions, decreased efficiency of irrigation and disruption of bed leveling, requiring the use of bed-leveling equipment every few years. to overcome these problems, the use of a two-way plow with two harrows which turns over the soil to both the left an...

Proso millet (Panicum miliaceum L.) is well-adapted for the Central Great Plains and could be planted in a winter wheat (Triticum aestivum L.)-millet-fallow rotation, resulting in two crops in 3 yr. To determine the most suitable tillage system for proso millet production within this rotation, seven tillage management systems were evaluated over a 6-yr period (1972-1977). The research was condu...

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...
