Unconventional methods of fertilizer placement to reduce losses of fall applied nitrogen
(1980-02-18)In two field experiments conducted in 1978-79, fall application of incorporated urea, or banded aqua ammonia, produced much less increase in yield and N-uptake than did spring application for barley grain. However, when ... -
Uncovering the genetic architecture of spike related traits in bread wheat: a viable alternative to increase yield potential
(2019-03-05)Based on the projected demand, further improvements in wheat grain yield are required. In this sense, exploring the genetic diversity associated with yield related traits is critical to derive superior progenies from ... -

Updated phosphorus rate guidelines for Manitoba
(2019-03-05)Recently Manitoba has experienced soil phosphorus (P) test levels declining into the low to very low range. This may be the result of high crop yields, an increase in crops like soybeans and canola that remove high P ... -
Upland acid sulfate soils and the effect of sulfide oxidation on soil genesis in Saskatchewan soils, Canada
(1986-02-20)Recent studies on upland acid sulfate soils in east central Saskatchewan generated interest in further study of sulfide oxidation and its effect on soil salinity, soil acidity, Solonetzic soil formation and other soil ... -
Uptake of foliar or soil application of 15N-labelled urea solution at anthesis and its affect on wheat grain protein
(1999-02-25)Late-season application of nitrogen fertilizer is of interest for increasing grain protein concentration in Canadian Western Red Spring wheat. The objective of this study was to determine the relative effectiveness of ... -
Uptake of soil and fertilizer phosphorus by nine varieties of wheat and nine varieties of barley
(1968-02-12)Barley is frequently considered to be more responsive than is wheat to phosphatic fertilizer applied to prairie soils, which are deficient in plant available phosphorus. An opinion has also been expressed that there is a ... -
URAN® (28-0-0) as an additive for reducing sodium bicarbonate antagonism of cyclohexanedione herbicides
(1992-02-20)Field tests were conducted in 1990 and 1991, to evaluate the potential of 28-0-0, (a mixture of ammonium nitrate and urea), as an additive when using sodium bicarbonate water for the dilution of cyclohexanedione herbicides. ... -
Urea phosphates

Urea treatment affects safe rates of seed placed nitrogen in Saskatchewan
(2005-02-17)Placing urea in close proximity to seed can cause seedling damage resulting in poor crop establishment. Plant densities are often well below the optimum, and plants that do emerge can exhibit poor vigor. Several strategies ...
