Nitrogen fertilization to malt barley enhances pea yield and quality, regardless of cover cropping, in the malt barley–pea rotation

open access: yesAgronomy Journal, Volume 117, Issue 3, May/June 2025.
Abstract Cover crop and N fertilization rate to malt barley (Hordeum vulgare L.) (NRMB) can affect soil residual NO3‐N that may alter pea (Pisum sativum L.) growth, yield, and quality in the malt barley–pea rotation. The effect of cover crop (oat [Avena sativa L.) cover crop vs. none) and NRMB (0, 40, 50, 60, 70, and 80 kg N ha−1) were examined on soil

Bentazon Determination by Conductometric Titrantion Using Acid Hydrocholoric as Titrant

open access: yes, 2016
Bentazon is an active principle of post-emergence herbicides used to control weeds in several crops of oilseeds, leguminous and cereals. Commercial formulations of these herbicides are found as concentrated solutions of the bentazon sodium salt.

Chlorophyll Fluorescence Imaging Reveals the Dynamics of Bentazon Action on Sunflower (Helianthus annuus L.) Plants

open access: yesAgronomy
Fluorescence photography was used to evaluate the effects of bentazon, an herbicide that inhibits electron transport in photosystem II, on sunflower, taken as a model plant. We measured chlorophyll fluorescence to visualize the penetration, distribution,

Enhancing Soybean (Glycine max L. Merr) Heat Stress Tolerance: Effects of Sowing Date on Seed Yield, Oil Content, and Fatty Acid Composition in Hot Climate Conditions

open access: yesFood Science &Nutrition, Volume 13, Issue 1, January 2025.
Seed yield, oil content, and protein content of soybean genotypes significantly changed under different temperature regimes. Temperature during the seed‐filling period affects the composition of fatty acids of soybean genotypes. High temperature during the seed‐filling period altered unsaturated fatty acid composition by increasing oleic acid and ...

Hollow Fiber–Supported ZIF‐8@GO Reinforced Sol–Gel for Preconcentration of Paraquat Before Determination by UV‐Vis Spectrophotometry

open access: yesJournal of Analytical Methods in Chemistry, Volume 2025, Issue 1, 2025.
A novel, sensitive, and efficient method was developed for the determination of paraquat in soil samples, centered on solid‐phase microextraction using hollow fiber–supported ZIF‐8@GO reinforced sol–gel combined with UV‐Vis spectrophotometry at 257 nm. Silica‐based ZIF‐8@GO was synthesized through sol–gel technology by reacting tetraethyl orthosilicate

Effect of Ammonium Sulfate and Bentazon on Sethoxydim Absorption

open access: yes, 1989
The effect of ammonium sulfate on absorption of14C-sethoxydim applied alone and with bentazon was studied in large crabgrass. Adding ammonium sulfate to14C-sethoxydim increased14C absorption 6-fold at 0.5 h after application but did not affect the amount

Efficiency of herbicides applied in post-emergence in maize and Urochloa brizantha cv. Marandu intercropping = Eficiência de herbicidas aplicados em pós-emergência em milho consorciado com Urochloa brizantha cv. Marandu

open access: yesAgro@mbiente On-line, 2014
- In the Cerrado region the consortium between corn and forage grass has been widely used aiming at establishment or renovation of pasture. The efficiency of the consortium can be obtained by suppression of competition between species consorts with the

Dryland pea seeding rates can be reduced without yield or economic penalty

open access: yesCrop, Forage &Turfgrass Management, Volume 10, Issue 2, December 2024.
Abstract Montana is the leading producer of field peas (Pisum sativum L.) in the United States. A density of 8 to 10 plants ft−2 is recommended when growing field peas in that state, but this recommendation is based on work done elsewhere. Field experiments were conducted in central Montana from 2021 through 2023 and at three additional locations in ...
