4 What’s This All About? 8.5 million acres of agricultural land 47,000 farms Avg. size is 181 acres More than 1/3 of all the land development that has taken place since 1607 has occurred in the last 20 years. Average annual rate of agricultural land converted to developed uses (acres) 23,260 Average annual rate of rural land converted to developed uses (acres) 69,480 More, smaller farms

5 Survey

6 If your wheat acreage decreased, what were the two most important reasons for the decrease? (Indicate the most important reason with a 1 and the second most important reason with a 2)

7 Survey What price/bushel level would it take for you to re- introduce wheat on your farm or increase wheat acreage? 6% $3.50-3.75 28% $3.76-4.00 48%$4.01 + 17% Do not plan to grow wheat regardless of price

11 Management Studies Bread Wheat Seeding Rate Plots were planted into conventionally tilled fields at rates of 15, 20, 25, 30, and 35 seeds per row ft. (25, 34, 43, 51, and 60 seeds per square ft.) at both sites. RCBD with 4 reps Karl 92, Soissons, TAM 110, Lakin, and Renwood 3260

17 Management Studies Bread Wheat Seeding Rate A quadratic effect of seeding rate on early season plant density was observed across sites in 2005 and 2006. The number of heads was increased with increased seeding rate up through 30 seeds row ft (1/3 more than the recommended seeding rate for SRWW). Yield was also increased with seeding rate, even at what would normally be considered extremely high rates.

18 Fertilization Randomized complete block design with eight replications was deployed to evaluate late- season N rates and timing. 0, 20, 30, and 40 lb N/ac applied as dissolved urea solution at GS37, GS 45, or GS 54. Sulfur was applied randomly to four of the eight replications at GS 30 in each year, resulting in this effect being nested within replication effect. Soissons (French Bread Wheat) Heyne (Kansas HRWW) Renwood 3260, (SRWW –strong gluten)

19 Fertilization Late-season N increased yield ~ 10% of the time. Late-season N never decreased yield. S at GS 30 caused foliar burn but not lost yield.

23 Loaf volume of Soissons, Heyne, and Renwood 3260 winter wheat varieties as affected by late season N (with S), 2001-2003.

24 Fertilization No effect of late-season foliar N on yield Grain and flour protein concentration of all three cultivars were consistently increased with the application of late- season foliar N applications up to 30 lb N ac -1. Variable response to S. Growth stage (45 versus 54) timing of late-season N application generally did not differ significantly as to the effect on grain, flour, and bread quality characteristics. Grain protein increase in response to applied N varied by cultivar. Application of 30 to 40 lb N ac -1 between GS 45 and 54 to winter bread wheat cultivars grown in humid, high rainfall areas likely will result in consistent increases in grain and flour protein concentration as well as increased water absorption and improvements in bread loaf volume. Other measured flour and baking properties were not commonly affected.

25 Disease Management Karl 92, Amelio, TAM 110, Renwood 3260, and Lakin. Seed for the seed treatment plots was treated with Baytan 30 seed treatment at 1.5 oz per 100 lb seed. Quilt was applied at 14 oz/ac to all treated plots at GS 37 (flag leaf emergence).
