Conservation tillage combined with cover crops or mulching may enhance natural enemy activity in agroecosystems by reducing soil disturbance and increasing habitat structural complexity. In particular, weed seed predation can increase with vegetation cover and reduced tillage, indicating that mulches may improve the quality of the habitat for weed seed foraging. The purpose of this study was to...

During cold acclimation, winter rye (Secale cereale L. cv Musketeer) plants accumulate antifreeze proteins (AFPs) in the apoplast of leaves and crowns. The goal of this study was to determine whether these AFPs influence survival at subzero temperatures by modifying the freezing process or by acting as cryoprotectants. In order to inhibit the growth of ice, AFPs must be mobile so that they can ...

The materials of long-term field experiments carried out in the forest-steppe Ob region Novosibirsk and northern Kuznetsk basin Kemerovo various types crop rotations on leached chernozems were analyzed to assess possibility developing organic farming. most stable rotation relation weeds is a grain-fallow with winter rye, where coefficient productivity decrease an increase infestation by 1 unit ...

Antifreeze activity is induced by cold temperatures in winter rye (Secale cereale) leaves. The activity arises from six antifreeze proteins that accumulate in the apoplast of winter rye leaves during cold acclimation. The individual antifreeze proteins are similar to pathogenesis-related proteins, including glucanases, chitinases, and thaumatin-like proteins. The objective of this study was to ...

A nutrient loss reduction strategy is necessary to guide the efforts of improving water quality downstream an agricultural watershed. In this study, effectiveness two winter cover crops, namely cereal rye and annual ryegrass, explored as a in watershed that ultimately drains into supply reservoir. Using coupled optimization-watershed model, optimal placements crops were identified would result ...
