Subject:
agronomy; crop yield; fertilizer rates; fertilizers
Abstract:
... Several recently developed and marketed fertilizers containing S and/or Zn that have been evaluated for their agronomic effectiveness are often compared with the traditional standard fertilizers on the basis of a single high fertilizer rate of the tested nutrient in terms of crop yield. This approach can provide an inaccurate or misleading conclusion that they are as good as or even better than th ...

Abstract:
... In the northern Great Plains, winter wheat (Triticum aestivum L.) grows across four seasons, allowing more time for nitrogen (N) to be lost to the environment. Recognizing uneven plant N uptake throughout the growing season, it has been established that split application of N can improve various growth parameters. However, climate plays a large role in the efficacy of split applications of N. Grow ...
