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...

Soils play a key role in the global carbon cycle. They can be a source or a sink of carbon and in ̄uence CO2 concentrations in the atmosphere. In order to calculate the carbon budget of a region, the effect of soil management practices on carbon sequestration in soils needs to be quanti®ed. Objectives of this experiment were to determine: (i) the effects of ridge till, plow till and no-till on t...

Effects of different tillage management on the growth and yield maize were studied from early June to September 2017. The experiment was set up with three treatments: traditional shallow moldboard plow straw removal (MT), sub-soiling/ /sub-soiling rotation mulch (ST) no-till/sub-soiling/no-till retention (NT). soil compaction layers, plant height, chlorophyll content, above-ground biomass deter...

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...

Introduction The Rodale Institute (Kutztown, PA) began experimenting with an Organic No–Till Plus system in 2004, where commercial crops (corn, soybean, pumpkin) were no-till drilled or planted into cover crops that were rolled with a roller/crimper. The roller consists of a large steel cylinder (10.5 ft. wide x 16 in. diameter) filled with water to provide 2,000 lb. of weight. The Rodale Insti...

The weed seed bank of a long-term tillage study in subarctic Alaska was studied at the end of 10 years of continuous spring barley (Hordeum vulgare L.). Tillage treatments were: no-till, disked once (spring), disked twice (spring and fall), and chisel plow (fall). Soil cores were obtained from each tillage treatment and seeds were manually separated from soil after washing through sieves. Tilla...

Fatty acid methyl esters (FAMEs) were used to `®ngerprint' soil microbial communities that evolved during 25 years of wheat-fallow cropping following native mixed prairie sod at Sidney, Nebraska, USA. Total ester-linked FAMEs (EL-FAMEs) and phospholipid-linked FAMEs (PL-FAMEs) were compared for their ability to discriminate between plots remaining in sod and those cropped to wheat or left fallo...

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...
