abstract in order to study the sensitivity of seven crops to total herbicide soil residue, an experiment was carried out under controlled conditions in 2009 at the college of agriculture, ferdowsi university of mashhad-iran. in this study 7 crops (pea, bean, lentil, corn, rape, beet and tomato), across 7 simulated soil residual concentration of total herbicide (0, 0.0002, 0.0005, 0.001, 0.002, ...

the seedbed preparation and cereal residue present due to limit of maize (zea mays l.) growing period are a major challenge in double cropping after winter cereals in iran as: shahrekord. in this research, effects of various seedbed preparation methods and crop residuea managements on vegetative growth and yield of forage maize (ksc 704) were studied in a barley-maize double cropping during 200...

Perennial grain production will likely present unique challenges for managing diseases that affect the productivity and longevity of crops being considered. Typical cultural practices effective at reducing soiland residue-borne pathogens, such as annual crop rotations, delayed fall planting, and tillage, are not feasible in perennial systems. Consequently, soiland residue-borne pathogens, and p...

Research was conducted on silt-loam Alfisols at the Pine Tree Branch (PTBS) and Cotton Branch (CBES) Experiment Stations. Prior to the initiation of this study, both study locations were cropped under CT; thus the results of this study represent a short-term NT history. Previous crops were sorghum (Sorghum bicolor L.) and soybean at PTBS and CBES, respectively. The research area was established...

In this study, we estimate rice residue, associated burning emissions, and compare results with existing emissions inventories employing a bottom-up approach. We first estimated field-level post-harvest rice residues, including separate fuel-loading factors for rice straw and rice stubble. Results suggested fuel-loading factors of 0.27 kgm (±0.033), 0.61 kgm (±0.076), and 0.88 kgm (±0.083) for ...

straw burned (Bird et al., 2001; 2002). Recent work in tropical and temperate rice ecosystems has determined The transition from open-field burning of straw residues to alternathat the operationally-defined mobile humic fraction tive residue management practices may affect soil C sequestration potential and the supply of nutrients to crops. A field study of dual(Na4P2O7 or NaOH extractable) is ...

in order to evaluate of pea, bean, lentil, wheat, rape and barley sensitivity to foramsulforun, rimsulforun and nicosulforun herbicides soil residue, a pot experiment was conducted at ferdowsi university of mashhad. experimental type was completely randomized design in factorial arrangement with three replications. treatments included herbicides (rimsulforun, foramsulforun and nicosulforun), he...

the effects of soil tillage methods and residue management were studied at miandoab agriculure station during 2003-2005. the experiment design was split block with the main plots devoted to residual management strategies (burning residue, crushing residue by disk, no treatment). subplots were tillage methods (moldboard plowing to 20-25 cm in fall, moldboard plowing to 20-25 cm in spring, moldbo...

Residue management has become a new challenge for Indian agriculture and agricultural growth, as well environmental preservation. The rice-wheat cropping system (RWCS) is predominantly followed in the Indo-Gangetic plain (IGP), resulting generating large volume of residue. Annually, India produces 620 MT crop residue, with rice wheat accounting 234 surplus 30% total. Farmers are resorting to bu...
