Canada is the world’s second largest exporter of wheat with 70% of its production exported annually. The herbicide era began in the 1940s with the introduction of 2,4-D, a phenoxy herbicide that was adopte...
متن کاملIncreasing the utilisation of grain when fed whole to ruminants
Feeding grain whole to cattle generally results in a lower digestibility than that obtained with processed grain. If this problem could be overcome, feeding with whole grain would reduce processing costs, and the slower rate of starch digestion in the rumen could improve fibre digestion with potential beneficial effects on intake and animal production. Two strategies are available to increase t...
متن کاملA simple method to estimate harvest index in grain crops
Several methods have been proposed to simulate yield in crop simulation models. In this work, we present a simple method to estimate harvest index (HI) of grain crops based on fractional post-anthesis phase growth ( fG = fraction of biomass accumulation that occurred in the post-anthesis phase). We propose that HI increases in a linear or curvilinear fashion in response to fG. The linear model ...
