Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...

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

Strip Crops and Intercrops Outperform Crop Rotations for Weed Management Under Conservation Agriculture in Zimbabwe

Weed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT High weed infestation remains a major constraint on crop productivity for smallholder farmers practising Conservation Agriculture (CA). Fewer, more diverse weeds are desirable to reduce competition and provide ecosystem services. Crop diversification can help, but it is not yet clear which species combinations and layouts are most effective ...

Yield of Short Duration Drought Tolerant Transplant Aman Rice Varieties as Influenced by Integrated Nitrogen and Weed Management Practices

Advances in Agriculture, Volume 2026, Issue 1, 2026.
Rice productivity varies substantially across rice varieties along with judicious nitrogenous fertilizer and weed management (WM) practices. At AFL, Bangladesh Agricultural University, we tested two cultivars of short‐duration drought‐tolerant T. aman (autumn) rice, Bangladesh Rice Research Institute (BRRI) dhan66 and BRRI dhan71, and how different ...

Ecological studies on the crabgrass, Digitaria sanguinalis SCPLI on the upland field.

Japanese Journal of Crop Science, 1951
1. In this ecological studies, the close relations among the crabgrass and several crops were observed in the upland field. 2. Branched ears of the crabgrass (dominant species) were correlated to numbers of its seed. 3. Falled seeds of this weed were found 218.2 in ten square centimeters after the sweet-potatoes were harvested.
