Morphological and physiological changes in barley cultivars under black oat competition [PDF]

Advances in Weed Science, 2021
Abstract Background Weeds compete with crops, demanding efficient control to avoid yield losses. Highly competitive cultivars are a cultural method that can increase weed suppression and reduce the effects of crop-weed competition. Objective The present study aimed to assess the competitive abilities of barley cultivars (crop) against black oat (weed ...

UFSMFW 2202 - Early black oat cultivar for ground cover

Crop Breeding and Applied Biotechnology, 2022
Abstract UFSMFW 2202 is an early black oat cultivar with high dry matter and grain yield potential. When used in rotation systems, the early cycle has the immediate advantage of allowing anticipated sowing of subsequent crop. Initially, the cultivar is recommended for the North and Northwest of Rio Grande do Sul.

Temperature changes in soil covered by black oat straw [PDF]

Pesquisa Agropecuária Brasileira, 2017
Abstract: The objective of this work was to evaluate the effect of different amounts of black oat (Avena strigosa) straw covering soil surface on soil temperature at different depths. The treatments consisted of 0, 3, 6, and 9 Mg ha-1 straw. Soil temperature was measured hourly by a thermocouple inserted at different depths (0, 5, 15, 30, and 50 cm ...

System Fertilization: a Viable Practice for Black Oat-soybean Crop [PDF]

Brazilian Archives of Biology and Technology, 2020
Abstract System fertilization is characterized by partial or total fertilizer application at the predecessor crop; and it can be a viable practice to soybean crop. This study aimed to determine the fertilizer management and fertilizer levels for black oat-soybean cropping system, in high fertility soils and no-tillage system.
