Abstract
An experiment was conducted in the greenhouse to evaluate urea
by comparing responses of irrigated wheat to treatments involving urea,
ammonium sulfate and sulfur coated urea (SCU). Grain y i e l d , total dry
matter, 100 seed weight and grain to stover r a t io were observed. The
wheat was an early maturing, short statured variety (Yecora Rojo).
The study experiment was conducted on an acid loam (pH 6.5) and
a calcareous clay loam (pH 7.6). The f e r t i l i z e r s were either surface
applied or soil incorporated at rates of 0, 50, 100, and 150 lbs. N
per acre. The experiment consisted of a factorial arrangement, four
replications and a completely randomized block design.
There was no significant difference in wheat grain y i e l d , total
dry matter, 100 seed weight and grain to stover r a t io resulting from
treatments that had received either urea or ammonium sulfate or between
plots that had received either urea or SCU.
Ammonium sulfate treatments produced significantly higher grain
y i e l d and total dry matter than treatments that had received SCU.
There were no significant differences in grain yield total
dry matter production, 100 seed weight and grain to stover ratio between
plots that had received surface application of nitrogen and those that
had received soil incorporation of the same material.
