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...

In order to solve the problem of low mechanization level hairy vetch harvesting, a feeding device for an anti-winding harvester was designed. Firstly, physical properties stalk were studied. According mechanical stalk, key components designed and analyzed, structure working principle described. Secondly, discrete element method used simulate analyze movement performance device. On this basis, t...

It has been established that the blood test is one of quick methods assessing physiological state body under action exogenous stimuli, what important when testing new feed additives in pig feeding. Studies morphological parameters showed feeding young pigs with starter additive “Activo” helped to increase red cells and hemoglobin level. Thus, content second group increased by 7.5 % compared con...

β-glucosidase is involved in the degradation of cellulose in soil and has the potential for monitoring biological soil quality. the objective of this study was to determine the effects of barley residue placement, burning, nitrogen fertilizer and tillage management on β-glucosidase enzyme after a period of 90 days. a field experiment was carried out based on a completely randomized design with ...

this experiment was conducted to improve the nutritive value of barley stubble for two consecutive years. after harvesting crop, at first year, a completely randomized design, with a 3 × 3 factorial experiment was conducted in which 27 plots were divided into nine treatments. the treatments including zero, 2.5 and five percent urea each with zero, three and six percent molasses were mixed with ...

In the current study area, livestock are an integral part of mixed farming system, and play very important roles as sources draught power, nutrition, cash income, employment poverty alleviation. However, feed shortage, especially during dry season, is most constraint to optimal productivity. This aimed investigate resources feeding practices, coping strategies with seasonal scarcity, identify m...

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...

.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...
