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 ... -
Effect of Seed Distribution and Population on Maize (Zea Mays L.) Grain Yield
(Oklahoma State University, 2013-12-01)Maize planting is normally accomplished by hand in the developing world where two or more seeds are placed per hill with a heterogeneous plant spacing and density. To understand the interaction between seed distribution ... -
Host resistance and diversity of Spiroplasma kunkelii as components of corn stunt disease
(2007-12)Corn stunt is an important plant disease for which successful control using resistant maize germplasm has been unsatisfactory in the past. It is unknown at present if the pathogen Spiroplasma kunkelii has the ability to ... -
Maize (Zea-maize L.) Grain Yield Respond to Nitrogen Applied at Different Distances Away from the Row
(Oklahoma State University, 2010-05-01)A one percent global increase in nitrogen use efficiency would be worth approximately 1 billion dollars (Raun and Johnson, 1999). It is thus important to apply nitrogen (N) midseason or split applied so as to improve ... -
Precision planting of maize (Zea mays L.)
(2012-12)Precision seed placement and the resulting leaf orientation have the potential to influence some of the parameters that controls productivity. The objectives of this work were to evaluate the impact of seed placement and ...
