Data from rodent antinociception models indicate that N-methyl-D-aspartate (NMDA) receptor antagonists do not produce antinociception alone or potentiate morphine antinociception, but do attenuate the development of morphine tolerance. This study examined the antinociceptive effects of the noncompetitive NMDA receptor antagonist dizocilpine, the competitive NMDA receptor antagonist (-)-6-phosph...

Soil organic carbon (SOC) pool is the largest among terrestrial pools. The restoration of SOC pool in arable lands represents a potential sink for atmospheric CO2. Restorative management of SOC includes using organic manures, adopting legume-based crop rotations, and converting plow till to a conservation till system. A field study was conducted to analyze soil properties on two farms located i...

Research was initiated at the Texas Experimental Ranch in 1981 to quantify the effects of 2 stocking densities, equivalent to 14 and 42-paddock rotational grazing (RG) treatments, on aboveground biomass dynamics, aboveground net primary production (ANPP), and harvest efficiency of forage. Baseline data were collected in 1981 from 3 adjacent 30-ha paddocks in a lepaddock, cell designed RG treatm...

A field experiment was conducted during kharif 2018 at Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (U.P.). The soil experimental plot sandy loam in texture, nearly neutral reaction (pH 6.7), low organic carbon (0.35%), available N (230 kg ha-1), P (20 ha-1) and K (189 ha-1). laid out Randomized Block Design with factorial concept. There were 13 treatments including 12...

Brassicaceae seed meals produce ionic thiocyanate (SCN (-)), a bioherbicidal compound. This study determined the fate of SCN (-) in a field soil amended with seed meals of Sinapis alba, Brassica juncea, and Brassica napus and quantified crop phytotoxicity by monitoring carrot ( Daucus carota) emergence. Meals were applied at 1 or 2 t ha (-1), and soils were sampled to 35 cm for SCN (-). Maximum...

Die Anforderungen an die moderne Landwirtschaft bedingen einen effizienten Ressourceneinsatz, auch bei der N-Düngung. Ökonomisch optimierte Entscheidungsregeln wurden mit Künstlichen Neuronalen Netzen (KNN) und Support-Vector-Machines (SVM) erzeugt und in der Anwendung mit einer betriebseinheitlichen Variante verglichen. Es zeigte sich, dass Einsparpotentiale von bis zu 69 kg N/ha möglich sind ...

The field experiment was conducted during Zaid season 2022 at the experimental of Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj Uttar Pradesh, India. soil plot sandy loam in texture, nearly neutral reaction (pH 7.3), low organic carbon (0.48%), available nitrogen (230 kg/ha), phosphorus (13.60 k...

Aminocyclopyrachlor is a pyrimidine carboxylic acid herbicide used to control broadleaf weeds and brush. Amending soil with activated charcoal is recommended to prevent off-site transport of aminocyclopyrachlor and non-target plant damage. We used the batch-equilibrium method to determine the concentration of aminocyclopyrachlor in a pseudo-steady state with biochar, soil, and biochar-soil syst...
