Field, greenhouse, and laboratory experiments were conducted at the Montana State University Southern Agricultural Research Center, Huntley, MT, USA, in 2012 and 2013, to evaluate the effectiveness of various postharvest-appliedherbicideson late-season control, fecundity, seed viability, andprogenyfitnessofKochia scoparia (kochia) in wheat stubble. Paraquat þ atrazine, paraquat þ linuron, and p...

In subtropical regions, we have an incomplete understanding of how long-term tillage, stubble, and nitrogen (N) fertilizer management affects soil biological functioning. We examined a site managed for 50 years using varying tillage (conventional till (CT) no-till (NT)), stubble (stubble burning (SB) retention (SR)), N fertilization (0 (N0), 30 (N30), 90 (N90) kg ha?1 y?1) to assess their impac...

Farmers in Mediterranean climate regions are increasingly growing canola (Brassica napus L.) wheat (Triticum aestivum L.)-based systems to break soil-borne pathogen disease cycles, control weeds, and enhance crop marketing opportunities. A 6-year rainfed cropping experiment was conducted near Ritzville, Washington USA from 2015 2021. The objective compare performance of winter spring canola, tr...

despite a shortage of animal feed in iran, cereal stubble is often underutilized due to agro-economic reasons. on the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. fat-tailed mehraban and ghezel ram lambs were p...

.soil microorganisms are important agents in nutrient cycling and energy flow. they are extremely sensitive to environmental changes. soil microbial biomass has been proposed as an index of soil stress and disturbance. the objective of this study was to determine the effects of barley (hordeum vulgare l.) residue amounts, burning, nitrogen fertilizer levels and tillage management on organic car...

Plant pathologists' traditional recommendations have been to clean-till fields. A few passes with the disk were good. Better yet, moldboard plow the residue under. Even better, burn the stubble, then plow it. Unfortunately, clean-tilling fields did not turn out to be a sustainable practice. Water and wind erosion claimed too much top soil and threatened to reduce the yield potential of our fiel...
