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...

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...

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...

this study was carried out to identify technical-agronomic factors impressible from fish farming in rice fields. this investigation carried out by descriptive survey during july-august 2009. studied cities including talesh, rezvanshahr and masal set in tavalesh region near to caspian sea, north of iran. the questionnaire validity and reliability were determined to enhance the dependability of t...

Recent developments in biofuel demand and the rapid adoption of modern transgenic hybrids are changing production systems towards more corn after corn, more intensive tillage, higher plant populations, and ever higher crop residue levels at harvest. Meeting society’s needs for food, feed, and fuel from grain corn, and in the future from corn stover, requires continued refinement of tillage syst...

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...

In practice, the operation of destroying plant residues is carried out separately, in general equipment mounted on back tractor. Equipment for such as cutters, platforms with rotors, shredders, etc. known. which works aggregate The disadvantages these equipments consist fact that they work independently and only carry remains leaving them ground, technology being additional passage same land in...

Theoretical studies were carried out using main provisions theory agricultural machines, theoretical mechanics higher mathematics. The corresponding calculations a PC in Mathcad 15.0 software environment, their graphic i...

and in the tillage pan was maintained at a high level only when crop residue returns increased and soil pH Long-term experiments are ideal for evaluating the influence of was maintained above 5.6 (Pikul and Allmaras, 1986). agricultural practices on soil organic carbon (SOC) accretion. Little is known about the influence of tillage and N fertilization on SOC Long-term use of N fertilizer also r...
