The influence of different methods of weed regulation on yielding and protein content in seeds of common bean (Phaseolus vulgaris L.)

Agronomy Science, 2018
The seeds of common bean, like other leguminous plants have high contents of protein with high biological value. Weed management is one of the most important problems in dry bean production.

An Urban Stormwater Contaminant Signature: Defining Priority Contaminants for Urban Stormwater Research

Water Environment Research, Volume 97, Issue 7, July 2025.
We identified a core suite of frequently detected contaminants in urban stormwater ponds using three complementary sampling methods. This urban stormwater contaminant signature (USCS) highlights cumulative exposures in pond ecosystems and supports more targeted monitoring of urban runoff.

Effect of Rice Cultivars and Herbicidal Combinations Integrations on Weeds and Yield of Broadcast-Seeded Rice Productivity and Economic Feasibility [PDF]

Journal of Plant Production, 2018
Nowadays there was an attitude from farmers to grow broadcasted seeded rice as an alternative to transplanted rice due to the scarce and costly labors in rice transplanting, but  broadcasted seeded rice suffer severely from weed competition where ...

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

Agronomy 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

Weed control and crop selectivity of post-emergence herbicides in common beans

Ciência Rural
: There are few options of wide spectrum selective herbicides registered for post-emergence weed control in common beans crop. The experiment aimed to test crop selectivity and weed control of post-emergence herbicides on common beans.

Efeito da pressão de trabalho e de modelos de pontas de pulverização sobre a eficiência de herbicida de contato em soja Operating pressure and spray nozzles effects on the efficiency of contact herbicide in soybeans

Engenharia Agrícola, 2007
Nos últimos anos, nas aplicações de herbicidas de contato em pós-emergência, tem-se verificado tendência de redução do volume de calda e a utilização de pontas de pulverização que operam com baixas pressões.

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

Food 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 ...

Implications of cereal rye cover crop termination timing and residue management on Palmer amaranth (Amaranthus palmeri) and sicklepod (Senna obtusifolia) control in peanut

Weed Technology
Weed management in peanut primarily relies on intensive herbicide programs. Integrating cereal rye as a cover crop may reduce herbicide input without compromising weed control.

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

Journal 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
