in order to determine the effect of different tillage methods on grain yield and yield components of two wheat cultivars an experiment was conducted in sanandaj in during 2005 and 2006-2007. experiment was carried out in a split plot design based on rcbd with four replications. the three methods of tillage, including moldboard plow, chisel plow and no tillage were arranged as main plots, and tw...

High residue conservation tillage systems for cotton (Gossypium hirsutum L.) production have been proposed as having the potential to be both economically and environmentally sustainable, and research regarding till­ age systems has indicated that several advantages may exist for conservation tillage systems compared to con­ ventional tillage systems. However, adoption of new farming systems on...

Tillage-induced changes in soil properties are difficult to predict, yet can influence evaporation, infiltration and howwater is redistributedwithin the profile after precipitation.We evaluated the effects of sweep tillage (ST) on near surface soil water dynamics as compared with an untilled (UT) soil during a 7-month period. Plots were established in a fallow field devoid of residue under stub...

This study was designed to investigate the effects of different tillage systems on some parameters such as soil salinity (pH, EC, SAR), soil density and nutrients in a nested experimental design with three treatments (no tillage, reduced tillage and conventional tillage) and three replications. Chenaran city fields were selected as the case study areas. Result of the statistical analysis indica...

Mechanized agriculture is increasing rapidly in the Cerrado region of Brazil, causing concerns about water quality, off-site impacts, and sustainability. Our objective was to determine the impact of tillage on soil biological activity and aggregate stability in an Oxisol typical to the region. Three different tillage practices common to the Cerrado region (no-till, disk harrow, and disk plow) a...

a mineral soil (Farnham and Finney, 1965), which provides a high potential for diffusion and storage of O2 Organic soils in the Everglades Agricultural Area (EAA) of southfor microbial utilization in the organic soil. Neller (1943) ern Florida, USA, are subsiding due primarily to oxidation by aerobic microorganisms. Since there are large C losses in drained Histosols, reported that soil O2 rang...

rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. a field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (brassica napus l. cv. hyola-401) during 2011-12 growing season at rice research institute of iran-department of mazandaran ...

this study carried out to evaluate the effect of different tillage systems on rapeseed yield (hayola 401) planted in corn residues. this experiment was done in moghan region with clay soils during 2009-2012. different seedbed preparation methods include mt: moldboard + disk tillage (conventional tillage was included), sct: stem crusher + chisel + disk tandem harrow, stt: stem crusher + double-d...
