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...

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...

The excessive application of manure on cropland areas can cause nutrients to accumulate near the soil surface and increase nutrient transport by overland flow. Inverting soils with high surface nutrient content could reduce runoff nutrient transport. This study was conducted to measure the effects of moldboard plowing on the redistribution of nutrients within the soil profile and nutrient trans...

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...

Stratification of nutrient availability, especially of P, that develops with continuous no-till (NT) can affect runoff nutrient concentration and possibly nutrient uptake. The effects of composted manure application and one-time tillage of NT on the distribution of soil chemical properties, root colonization by arbuscular mycorrhizae (AM), and plant P uptake were determined. Research was conduc...

Extreme meteorological phenomena resulting from climate change caused by anthropogenic emissions of greenhouse gases (GHG) require the implementation CO2 mitigation practices various industries, including agriculture. Owing to varying soil, climatic, and agrotechnical characteristics, they may have different efficiencies in mitigating soil emissions. The aim this study was evaluate impact three...

Compared to conventional tillage (CT) system (e.g. moldboard plowing (Moldboard-CT) and chisel (Chisel-CT)) adoption rate of conservation systems no-till (NT) strip-till (ST)) in surface- irrigated farms is considerably low. A three-year field study was conducted evaluate corn (Zea mays L) productivity four ranging intensity soil disturbance (i.e. Moldboard-CT, Chisel-CT, ST, NT) a furrow-irrig...

the main object of this study was to evaluate the effect of tillage and crop residues management of barley (hordeum vulgare l.) on quantification and qualification yield of corn (zea mays l.). treatments were laid out in complete randomized block design with seven treatments and three replications and include (1) fire of straw and stubble, plow, disc and furrower (2) gathering and transfer of s...
