Defining critical leaf‐ and petiole‐potassium concentrations for monitoring cotton nutritional status

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Plant tissue testing is an effective tool for diagnosing crop nutritional status; however, critical tissue‐potassium (K) concentrations have not been established for modern cotton (Gossypium hirsutum L.) cultivars. We aimed to define critical leaf‐ and petiole‐K concentrations at various growth stages for optimal cotton production.

Summer cover crops impact weed biomass and C and N acquisition

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Despite the potential to improve nutrient cycling, weed suppression, and system resilience, mixed‐species cover crops remain underutilized in organic irrigated systems. This study evaluated the influence of cover crop diversity and associated weeds on biomass production (both cover crops and weeds), as well as carbon (C) and nitrogen (N ...

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Integrating early spring‐planted barley or oat for Palmer amaranth management in soybean

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Fall‐planted cover crops (CCs) are widely used for weed suppression, but CC establishment challenges after fall harvest in temperate regions necessitate alternative approaches. The objectives of this study were to evaluate the integrated effect of spring‐planted barley or oat CC and herbicide programs for CC biomass production, Palmer amaranth

Osmo and hydro priming improvement germination characteristics and enzyme activity of Mountain Rye (Secale montanum) seeds under drought stress [PDF]

, 2012
Impacts of various concentrations of polyetylenglycol 6000 (PEG 6000)(0, -9, -11, -13 and -15 bar) and hydro priming on Mountain Rye (secale montanum) germination characteristic and enzyme activity were evaluated under drought stress in the seed ...

Genome‐Wide Analysis of Tritipyrum HSFs and Functional Characterization of TtHSF97 for Salt Tolerance

Food Science &Nutrition, Volume 14, Issue 1, January 2026.
This study focuses on the mechanism of heat shock transcription factor (TtHSF) mediated salt stress tolerance in Tritipyrum. A total of 103 TtHSF genes were identified through genome‐wide analysis, with the function of the TtHSF97 being emphasized.

Sowing time affects the abundance of pests and weeds in winter rye [PDF]

, 2006
Selection of an appropriate sowing time for some winter rye (Secale cereale) cultivars could reduce the need for crop protection measures. In this study the occurrence and status of pests and weeds in relation to sowing time and growth habit of winter ...

The Soil Erosion Paradox Re‐Examined: Alluviation and Land Use History in a Small British Lowland River Catchment in the Late Holocene

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Modern studies show that soil erosion results in a loss of ecosystem function, particularly fertility, and is a cause of declining agricultural yields. However, despite the well‐attested high rates of soil erosion across Roman and medieval Europe there appears to have been little or no soil‐associated decline in agricultural production—the ...

Comparing conventional and improved organic vegetable rotations, yields and nitrogen husbandry [PDF]

, 2010
During 2005 to 2009 three approaches to organic vegetable rotations were compared to a conventional rotation in an interdisciplinary project. The organic rotations differed in their reliance on animal manure vs.
