The effects of three levels of soil moisture content (8-10, 10-12 and 12-14% d.b.) and three levels of plowing depth (15, 20 and 25 cm) on draft, specific draft and drawbar power requirement of a 7-shank chisel plow in a clay loam soil were investigated. The experimental design was a randomized complete block design with a 3×4 factorial. The effect of plowing depth on all of the parameters ment...
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract The traditional tillage implement, the Maresha plow, and the tillage systems that require repeated and cross plowing have caused poor rainfall partitioning, land degradation and hence low water productivity in Ethiopia. Conservation tillag...

Influence of cultural practices on incidence of foot rot in potrichoides was added. winter wheat. Plant Disease 69:948-950. The three preplant tillage systems evaluated in this study were 1) conCrop rotation, preplant tillage, cultivar selection, nitrogen fertilization, and ben...
could be optimized using modified NT systems (including ST) and starter fertilizer. In Iowa Mallarino et al. (1999) Utilizing conservation tillage practices and increasing fertilizer N found that ST frequently increased early growth but seluse efficiency for corn (Zea mays L.) are necessary for optimizing dom increased corn grain yields compared with NT. growers’ profits and for minimizing loss...
Equilibrium-tension lysimeters were used to evaluate and compare dissolved reactive phosphorus (DRP) leaching from a prairie and fertilized no-tillage and chisel-plowed corn agroecosystems on Plano silt loam (fine-silty, mixed, superactive, mesic Typic Argiudolls) in south central Wisconsin during four monitoring periods, March through April 1996, 1997, and 1998, and from January 1999 through S...
Crop management practices (tillage, residue management, fertilization, etc.) define the soil environment to which crops are exposed and through these environmental conditions control crop growth. The purpose of this paper is to report the response of winter wheat (Triticum aestivum L.) to long-term (10 years) application of fallow tillage practices (plow, sub-till, and no-till) and N fertilizat...
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...
the aim of this study was to evaluate the effect of long-term reduced tillage on yield and weeds of spring barley. treatments consisted of three tillage systems including: (a) conventional tillage (ct), (b) reduced tillage (rt), and (c) herbicide tillage (ht) as the main plot, and two cultivars of spring barley (tocada and rastik) as subplots. the results showed that the yield of both cultivars...
Bing, L.A. and Lewis, L.C., 1993. Occurrence of the entomopathogen Beauveria bassiana (Balsamo) Vuillemin in different tillage regimes and in Zea mays L. and virulence towards Ostrinia nubilalis (Hiibner) Agric. Ecosystems Environ., 45: 147-156. The entomopathogen, Beauveria bassiana (Balsamo) Vuillemin, is an important component in the corn (Zea mays L. ) agroecosystem; this pathogen was found...
