Economics of the Greenseeder Hand Planter

Agrosystems, Geosciences &Environment, Volume 2, Issue 1, Page 1-7, 2019., 2019
Core Ideas Break‐even corn yield increase for a US$50 Greenseeder hand planter is 1.12%. A US$50 Greenseeder hand planter needs to use 12.19% fewer seeds, and reduces labor man‐days by 38.66%. If used for fertilization, the Greenseeder hand planter could increase corn yields up to 10.82%.

Reduced‐lignin alfalfa production in the water‐limited environments of the US Central Great Plains

Agronomy Journal, Volume 117, Issue 3, May/June 2025.
Abstract Previous studies indicate reduced‐lignin (RL) alfalfa (Medicago sativa L.) cultivars as a more digestible livestock feed option with minimal reductions in biomass than conventional alfalfa cultivars at the same growth stage, allowing for harvest flexibility. However, these findings are derived from environments with adequate moisture. Thus, RL

From Field Experiments to Regional Forecasts: Upscaling Wheat Grain and Forage Yield Response to Acidic Soils

Agronomy Journal, Volume 111, Issue 1, Page 287-302, January–February 2019., 2019
Core Ideas Wheat varieties differ in forage and grain yield in their tolerance to acidic soils. Grain yield maximized at soil pH of 5.8 and 4.8 for sensitive and tolerant varieties. Forage yield maximized at soil pH of 6.0 and 5.5 for sensitive and tolerant varieties.

Soil pH influence on cotton lint yield and quality

Agrosystems, Geosciences &Environment, Volume 8, Issue 1, March 2025.
Abstract Increases in cotton (Gossypium hirsutum L.) production across Oklahoma due to various circumstances have led to cotton planted on soils that have been traditionally managed for differing crops, specifically winter wheat. Many of these soils are possibly acidic in nature due to natural and anthropogenic activities such as excessive ammonia ...

Evapotranspiration Rates of Turf Bermudagrasses under Nonlimiting Soil Moisture Conditions in Oklahoma

Crop Science, Volume 58, Issue 3, Page 1409-1415, May–June 2018., 2018
Due to limited water availability and increasing water costs, it is essential to identify and utilize turfgrasses with reduced water use rates. The objective of this study was to evaluate the evapotranspiration rates of bermudagrass (Cynodon spp.) genotypes under nonlimiting soil moisture conditions in the field at Stillwater, OK.

Evaluation of tissue phosphorus concentrations as diagnostic tool for phosphorus nutrition in corn

Soil Science Society of America Journal, Volume 89, Issue 2, March/April 2025.
Abstract Phosphorus (P) management in corn (Zea mays L.) traditionally relies on soil testing, but other diagnostic tools, such as tissue analysis, can be used to assess nutrient management. This study aimed to evaluate plant tissue analysis, Normalized Difference Vegetation Index (NDVI), and Soil Plant Analysis Development (SPAD) readings as ...

On‐Farm Winter Wheat Response to Nitrogen‐, Phosphorus‐, Potassium‐, and Sulfur‐Rich Strips in Oklahoma

Crop, Forage &Turfgrass Management, Volume 3, Issue 1, Page 1-11, December 2017., 2017
Core Ideas Thirty‐two percent of the locations had an increase in grain yield with increased nutrient inputs. Wheat response to additional N was potentially due to underestimated yield potential or N losses attributable to ammonia losses, immobilization, leaching, or environmental conditions.

Micronutrients concentration and content in corn as affected by nitrogen, phosphorus, and potassium fertilization

Agrosystems, Geosciences &Environment, Volume 7, Issue 4, December 2024.
Abstract The interaction between nitrogen (N), phosphorus (P), and potassium (K) fertilizers significantly impacts the uptake of micronutrients in corn, influencing their availability in soil and uptake by plants. Understanding the interaction of macro‐ and micronutrients is a prerequisite to targeting nutrient balance in crop production.

Predicting Early Season Nitrogen Rates of Corn Using Indicator Crops

Agronomy Journal, Volume 109, Issue 6, Page 2863-2870, November–December 2017., 2017
Core Ideas Early season N deficiencies in corn are hard to recognize, or they appear later in the season, and are too late to correct the deficiency. Indicator crop growing over the winter and early spring cycle makes perfect sense in terms of being able to detect N deficiencies earlier in the growing season. Indicator crop concept could apply to other

Cambios en fracciones de fósforo en Inceptisoles y Mollisoles por aplicaciones de vinaza y/o cloruro de potasio Changes in fractions of phosphorus in Inceptisols and Mollisols for applications of vinasse and /or potassium chloride

Acta Agronómica, 2010
Con el fin de determinar el efecto que la aplicación de vinaza puede tener sobre las fracciones de fósforo y su relación con la acumulación de biomasa total en maíz dulce, un experimento en invernadero fue realizado con suelos de los municipios de ...
