By-plant Prediction of Corn (Zea mays L.) Grain Yield Using Height and Stalk Diameter
(Oklahoma State University, 2011-05-01)Current methods for determining midseason nitrogen (N) rates in corn have used normalized difference vegetation index (NDVI), and in some cases, plant height and intra-specific plant competition. Another parameter that can ... -
By-plant Sidedress Nitrogen in Corn (Zea Mays L.) Based on Plant Height and Normalized Difference Vegetation Index
(Oklahoma State University, 2012-07-01)Current methods of applying nitrogen (N) fertilizer do not treat small scale variability that is known to exist. Variations in corn grain yield can be found from one plant to the next. With knowledge that yield potential ... -
Calendar spread options for storable commodities
(2013-12)Previous studies provide pricing models of options on futures spreads. However, none fully reflect the economic reality that spreads can stay near full carry for long periods of time. A new option pricing model is derived ... -
Corn Sensor Development for By-plant Management
(Oklahoma State University, 2012-07-01)Corn grain yield prediction and by-plant nutrient management have become a major research topic. This research was conducted to develop a sensor to improve by-plant management by detecting plant location and measuring corn ... -
Economic study of alternative best management practices for swine effluent application to corn in semiarid climate
(2004-12)Scope and Method of Study: The intent of this study was to analyze the economic implications of alternative irrigation systems (subsurface drip water irrigation and center pivot sprinkler irrigation) in Texas County, ... -
Effect of the method and rate of planter applied nitrogen on corn and grain sorghum production
(2023-05)In Oklahoma corn (Zea mays) and grain sorghum (Sorghum bicolor L) account for nearly 20% of all the total value of farmed cropland in the state. Fertilizer, specifically nitrogen (N) is one of the greatest input cost and ... -
How Much Would It Be worth to Know the Wasde Report in Advance?
(Oklahoma State University, 2013-12-01)Past research has shown that prices move in response to WASDE reports, but have only looked at price movements immediately prior to and after a report. This research seeks to determine the profitability of trading based ... -
Identification of optical spectral signatures for detecting cheat and ryegrass in winter wheat, and determination of optimum rate and growth stage of foliar applied phosphorus in corn
(2004-07)Site specific weed management requires the identification of crop and weed species in a mixture. Reflectance spectra were used for the detection of cheat and ryegrass in winter wheat under greenhouse conditions. The three ... -
Interactive effect of nitrogen, phosphorous, and potassium fertilization on corn (Zea mays L.)
(2022-12)Corn (Zea mays L.) is a high-yielding C4 plant that is cultivated all over the world as a food, feed, and biofuel source. Corn plantations in the southern Great Plains have risen during the last two decades, particularly ... -
Management of double-crop corn system
(Oklahoma Cooperative Extension Service, 2022-05) -
Performance Tests of Corn Varieties and Hybrids 1954
(Oklahoma Agricultural Experiment Station, 1954-12) -
Using informative Bayesian priors and on-farm experimentation to predict optimal site-specific nitrogen rates
(2023-05)Precise site-specific nitrogen applications will reduce excess nitrogen fertilizer run-off and have corresponding environmental benefits. Adoption of site-specific nitrogen application technology has been slow, and many ... -
Yield response of corn and grain sorghum to row offsets on subsurface drip laterals
(Elsevier BV, 2018-09-30)Subsurface drip irrigation (SDI) is a micro-irrigation system that could be adopted by producers in the semi-arid regions around the world for efficient use of water. Yet, several crop management issues related to SDI ...
