Phosphate system fertilization in no-tillage Oxisols: Effects of temporal, horizontal, and vertical distribution of available phosphorus in the soil. [PDF]
Abstract 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.

Genetic dissection of crown rust resistance in oat and the identification of key adult plant resistance genes. [PDF]
Abstract Crown rust (Puccinia coronata f. sp. Avenae Erikss.) poses a significant threat to oat production worldwide. The most effective strategy for managing this disease involves identifying, mapping, and deploying resistance genes to develop cultivars with enhanced resistance.

Pre-Crop Choice Shapes Nematode-Attached Bacterial Communities Associated With Reduced Pratylenchus penetrans Invasion of Barley Roots. [PDF]
Plant species vary in how they shape nematode‐suppressive soil microbiomes, and these legacies influence the subsequent crop. Suppressive microbiomes contain specific bacterial taxa that attach to the nematode cuticle, leading to reduced nematode invasion into the root system of the host.

Non-destructive analysis of photosynthetic pigments in Avena strigosa and Avena sativa
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.
