The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

In order to investigate the eff ect of transition of mounted implements from operation to transport on longitudinal stability of a tractor that works on sloping land, a mathematical model was developed. In this model two operation modes for a mounted chisel plow were considered: penetration of the plow into the soil and depth reduction of it, and the eff ects of transferred forces and torques f...

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...

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...

Dryland farming in the Mediterranean climate of the Pacific Northwest, USA supports extremely low earthworm populations under conventional tillage. Increases in earthworm populations are being observed in fields under no-till cropping systems. A 30+ year experiment with four tillage levels in a pea (Pisum sativum L.)-winter wheat (Triticum aestivum L.) rotation was evaluated for earthworm popul...

Abstract This paper reviews and analyzes the impact of residue burning on environment human health, influence ex-situ in-situ management reducing pollution improving soil crop yield, farmers’ economic benefits. Paddy is cultivated 43.8 Mha in India, producing 118.43 Mt grain an estimated 165.8 straw. Burning most common practice for managing rice residues mainly due to its simplicity, low cost,...
