FORAGE YIELD AND COMPOSITION OF Avena strigosa Schreb AT DIFFERENT HARVESTING FREQUENCIES AND INTENSITIES

Agrociencia, 2022
Harvesting frequency and intensity are management criteria in forage plants and their choices affect herbage yield and quality. The objectives of the study were to evaluate herbage yields of morphological components and chemical composition (crude protein, neutral detergent fiber and acid detergent fiber) of Saia oats (Avena strigosa Schreb) at three ...

Cover crop productivity and subsequent soybean yield in the western Corn Belt

Agronomy Journal, Volume 112, Issue 4, Page 2649-2663, July/August 2020., 2020
Abstract Cover crops (CC) in corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] rotations may prevent N loss and provide other ecosystem services but CC productivity in the western Corn Belt is limited by the short growing season. Our objective was to assess CC treatment and planting practice effects on CC biomass, spring soil nitrate ...

Productivity of black oats: Avena strigosa Schreb. on chernozem and its significance as food and medicine

Selekcija i semenarstvo, 2023
Oats are of great economic importance. This species is unfairly neglected and less cultivated in the world and our country, because other small grains give a higher yield. This study aimed to test black oats - Avena strigosa Schreb. and examine its morphologically productive properties on chernozem.

Carbon concentration predicts soil contamination of plant residues

Agricultural &Environmental Letters, Volume 5, Issue 1, 2020., 2020
Plant biomass can be corrected for soil contamination knowing C concentration. Knowing this association will lead to more and better estimations of surface residue mass with conservation agricultural management. Little practical difference existed among plant sources in the association between ash and C concentrations. DM = dry matter.
