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 ...

Introduction of Food‐Based Cover Crops Reduces Weed Control Frequency, Improves Land Productivity, and Increases Income of Robusta Coffee Farms

Advances in Agriculture, Volume 2026, Issue 1, 2026.
Coffee (Coffea canephora) takes 2 to 3 years to begin yielding, during which period the young coffee plants do not fully occupy the land. Introduction of fast‐growing food crops during these early stages will help maximize land use, provide early income, improve soil health, reduce weed pressure, and moderate the microclimate.

Genetic divergence among African cowpea lines based on morphoagronomic traits. [PDF]

, 2019
The aim of this study was to estimate the genetic divergence between African cowpea lines from the Cowpea Germplasm Bank of Embrapa Meio-Norte, Brazil. The morphoagronomic diversity of 57 cowpea lines was assessed using multivariate analysis.

Na+ and/or Cl− Toxicities Determine Salt Sensitivity in Soybean (Glycine max (L.) Merr.), Mungbean (Vigna radiata (L.) R. Wilczek), Cowpea (Vigna unguiculata (L.) Walp.), and Common Bean (Phaseolus vulgaris L.)

International Journal of Molecular Sciences, 2021
Grain legumes are important crops, but they are salt sensitive. This research dissected the responses of four (sub)tropical grain legumes to ionic components (Na+ and/or Cl−) of salt stress.

Grazing and cover crop effects on soil health during transition to organic production

Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract The authors studied the efficacy of six objective‐based, reduced tillage cover cropping systems with or without livestock grazing to induce changes in soil condition and soil health on a fine sandy loam during the organic transition phase in the northern Great Plains.
