Using Thermal Units To Predict Biomass Accumulation And Total Nitrogen Uptake For Cover Crops In Arkansas, Mila Victório Pessotto
Using Thermal Units To Predict Biomass Accumulation And Total Nitrogen Uptake For Cover Crops In Arkansas, Mila Victório Pessotto
Graduate Theses and Dissertations
Including cover crops in agricultural production systems is an important management practice. Cover cropping can improve soil health, increase plant-available nitrogen (N), provide surface residue to prevent erosional soil loss, increase water infiltration, and increase weed suppression. Cover crops growth can be predicted using thermal days or growing degree days [GDD] similar to commodity crops such as corn (Zea mays L.) or rice (Oryza sativa). Growing degree day calculations are a well-known tool to predict crop growth stage or development stage and can be adapted for use in any plant species, including cover crops. Identifying and developing the relationship between …
Phenotypical Characters Associated With The Loss Of The Seed And The Production Of Biomass In Panicum Coloratum Var. Makarikariense, Maria F. Moresco Lirusso, Mónica B. Sacido, Guillermo R. Pratta, Silvina A. Felitti
Phenotypical Characters Associated With The Loss Of The Seed And The Production Of Biomass In Panicum Coloratum Var. Makarikariense, Maria F. Moresco Lirusso, Mónica B. Sacido, Guillermo R. Pratta, Silvina A. Felitti
IGC Proceedings (1997-2023)
Since the beginning of humanity, plants have been manipulated by humans by artificial selection to obtain changes in their characteristics. This progress has been achieved through the domestication of the species. Panicum coloratum is a species of summer perennial grass, megathermic, tolerates waterlogging, cold and slightly saline soils. It is of African origin and used as fodder in various parts of the world. In Argentina around 130.500 hectares are sown, the most widespread varieties are: var. coloratum, and var. makarikariense Goossens. Its characteristics of determined flowering and ununiform ripening within the panicle, added to a very low retention of …
Forage Yield Of Oat On The Four Altitude Regions Of The Qinghai-Tibetan Plateau, H. B. Zhang, C. T. Liu, J. Q. Deng, X. L. Yang
Forage Yield Of Oat On The Four Altitude Regions Of The Qinghai-Tibetan Plateau, H. B. Zhang, C. T. Liu, J. Q. Deng, X. L. Yang
IGC Proceedings (1997-2023)
Forage oat (Avena sativa L.) for livestock in Qinghai-Tibet Plateau may be used biomass under widely different altitude conditions. To assess the effect of altitude on the biomass of oats, we conducted an experiment to explore the adaptability of forage oat Jiayan No. 2 in different altitudes for better agronomic traits and higher forage yield. Four regions included Hezheng county (2207 m a.s.l) and Tianzhu county (2407 m a.s.l), Gansu province, Haiyan county (3042 m a.s.l), Qinghai province and Hongyuan county (3460 m a.s.l), Sichuan province were selected, and agronomic data as well as dry matter yield were determined. …
Benefits Of Cover Cropping Systems In Walnut Orchards As Sustainable Agricultural Practice, Ana Medic, Consuelo B. Baez Vega
Benefits Of Cover Cropping Systems In Walnut Orchards As Sustainable Agricultural Practice, Ana Medic, Consuelo B. Baez Vega
CSU Journal of Sustainability and Climate Change
In recent years walnut orchards implemented cover crops in between rows to improve soil’s quality, lessen soil’s erosion, increase organic matter, manage nutrient movement and availability, enhance water retention, and expand microbe, insect, and flora diversity. Commonly selected cover crops in California are from families Poaceae, Brassicaceae, and Fabaceae. Considerations should be made when choosing a particular cover crop mixture to enhance multiple benefits and improve sustainable practices in orchard settings. An experiment was conducted in a walnut orchard to compare functionality and benefits of three systems multi-crop, monocrop, and no vegetation cover crop system. The following components were evaluated: …
