Use Efficiency

Wheat nitrogen-use efficiency in the Yaqui Valley has been estimated at about 0·31. The nitrogen that is not recovered by the crop has important environmental costs that have regional and global consequences. In addition, these nitrogen losses represent an important reduction in farm income. The objective of the present work was to validate a technology that includes the use of N-rich strips together with the GreenSeeker™ sensor and a crop algorithm in farmers' fields with the ultimate goal of improving nitrogen-use efficiency through site-specific nitrogen management in irrigated spring wheat. During the wheat crop cycle 2002/03 and 2003/04, 13 validation experiments of c. 1 ha each were established in farmers' fields in the Yaqui Valley. After the validation phase, during the wheat crop cycle 2005/06, eight technology transfer trials were established in farmers' fields; these had on an average an area of 10 ha each. Both the validation and technology transfer trials compared the farmers' conventional nitrogen management use v. the use of the N-rich strip together with the Green Seeker™ sensor and a crop algorithm to derive N recommendations for each individual field. The results of the validation trials showed that on an average over all locations, farmers were able to save 69 kg N/ha, without any yield reduction. At the price of US$0.9 per unit of N in the valley when these experiments were established, this represented savings to the farmers of US$62/ha. The technology transfer trials demonstrated that, in large commercial areas with an average size of 10 ha, farmers could improve their farm income by US$50/ha, when using sensor based N management. The combination of the N-rich strip, together with the use of the sensor and a crop algorithm to interpret the results from the sensor, allowed farmers to obtain significant savings in N use and thus in farm profits. Farm income was increased by US$56/ha, when averaged over all trials in all years.

Wheat Blossom Midge

Orange wheat blossom midge damage can impart serious loss of quality to Canadian hard red spring wheat. The extent of wheat quality deterioration is highly variable and not well related to degree of visual midge damage. Midge-damaged hard red spring wheat exhibits very high protein content, reduced flour yield, dark flour color, increased flour ash, weak sticky dough properties, low baking absorption and poor bread quality. Midge-damaged wheat contains normal levels of α-amylase and proteolytic enzymes. Severely midge-damaged wheat exhibits inferior gluten protein quality, but the cause remains obscure. The poor baking quality of severely midge-damaged wheat is associated with an unusually low sodium dodecyl sulfate (SDS) sedimentation volume. Samples with visual evidence of midge damage can be rapidly screened for quality defects on the basis of protein content and SDS-sedimentation volume. Aerial applications of Cygon and Lorsban to fields of midge-infested hard red spring wheat significantly reduced visual midge damage, and significantly reduced the extent of wheat quality deterioration.Key words: Midge (orange wheat blossom), wheat (spring), insecticide treatment
