Weed Emergence in a Soil with Cover Crops in an Agroecological No-Tillage System [PDF]
Planta Daninha, 2018 : The cultivation and deposition of cover crops residues on the soil surface can reduce weed emergence. The objective of this study was to evaluate the emergence of weeds, in a greenhouse, on a soil with cover crops in an agroecological no-tillage system.

Phosphate system fertilization in no-tillage Oxisols: Effects of temporal, horizontal, and vertical distribution of available phosphorus in the soil. [PDF]
J Environ QualAbstract System fertilization enhances logistics and phosphorus (P) use efficiency, but its effects in high P‐export systems, particularly regarding fertilization timing, placement, and distribution, remain unclear. This study evaluated P fertilization timing (90, 45, and 0 days before winter crop sowing [DBS]), placement (banded vs.

Mapping crown rust resistance in the oat diploid accession PI 258731 (Avena strigosa). [PDF]
PLoS OneOat crown rust, caused by Puccinia coronata Corda f. sp. avenae Eriks. (Pca), is a major biotic impediment to global oat production. Crown rust resistance has been described in oat diploid species A. strigosa accession PI 258731 and resistance from this accession has been successfully introgressed into hexaploid A. sativa germplasm.

Non-destructive analysis of photosynthetic pigments in Avena strigosa and Avena sativa
Australian Journal of Crop Science, 2019 Chlorophylls and carotenoids are the main photosynthetic pigments in plants. The photosynthetic potential of crop plants is used to determine the correct rate of nitrogen fertilization. To date, no studies have been conducted to understand the relationship between different methods of measurement of photosynthetic pigments in oats.
