It is widely assumed that living in rural Iowa means you live near a field of corn or soybeans. It is common to see large equipment during spring and fall and most people are aware that care should be given when using certain pesticides near these fields. In general, most everyone knows what to expect. Now there’s something new dotting the Iowa landscape . . . Vineyards! Like row crops, vineyards also use farm equipment and pesticides. We would like to take you on a written tour of what you might expect in a vineyard throughout our growing season. For a “real” tour, contact a local grape grower!

During adolescence, nutrition needs are high; however the literature shows that few adolescents are following standardized nutritional requirements. A few weeks before an intervention about nutrition to high school adolescents in Lausanne, they were invited to fill in a self-reported questionnaire about their nutrition modes and habits, and their self-image satisfaction (N = 198). Results show that only 5% of youth are eating 5 fruits and vegetables per day and only 29% 3 to 5 dairy products. 21% of female and 6% of boys are not satisfied about their self-image, and those exhibiting a poor self-image tend to adopt health compromising eating patterns in a higher proportion. During adolescence it is important not only to investigate the nutritional habits but also one's self image.

Soybean cyst nematode (SCN) causes the greatest yield loss of any single pathogen of soybean in Iowa. An estimated 50 million bushels were lost in Iowa to SCN in 2004. Damage from SCN is not limited to yield loss from root feeding; SCN also makes other diseases like sudden death syndrome, iron deficiency chlorosis, Pythium, Phytophthora root and stem rot and brown stem rot worse. Once established in a field, SCN cannot be eradicated. However, the use of multiple management tactics can help minimize yield loss.

Producers continually strive for high yielding soybeans. The state-wide average yield for Iowa is now more than 50 bu./acre. The “yield plateau” reported by many producers does not exist, and is a perception largely brought on by misuse of an oversimplified management system. High yielding soybeans are achieved through improved and targeted management decisions. Improved agronomic decisions for soybeans are critical since soybean is very sensitive to stresses that influence soybean growth, development and yield.

As a result of higher seed prices, improved planters and weed management programs, soybean growers are more aware of the importance of seeding rates and optimal plant populations at harvest. A harvest population of approximately 100,000 uniformly distributed plants per acre will maximize economic return in Iowa regardless of row spacing. There appears to be no economic advantage to harvest populations greater than, or less than, 100,000 plants per acre. Economics, however, should be considered carefully when striving for higher harvest populations since seed is expensive. Timely management, such as weed management, is more critical at low plant populations.

Planting soybeans in rows narrower than 30 inches can improve yield potential. Most Midwest research documents that narrow rows (less than 30 inches) yield greater than wide rows (30 inches or greater). On average in Iowa a 4.5 bu./acre yield increase can be expected using 15-inch row spacing, compared to 30-inch row spacing. These data have been fairly consistent for the past 20 years.

The planting date for soybeans should be based on seedbed conditions and calendar date rather than soil temperature. The optimum time to plant soybeans in Iowa is the last week of April for the southern two thirds of Iowa and the first week of May for the northern one third of Iowa.

The Food Assistance Monthly Participation Report is a monthly summary of Food Assistance program participation, Statewide and for each Iowa county. Breakouts are reported for participants also in the FIP program, those only receiving Food Assistance, and those that are receiving economic assistance under other programs (primarily Medicaid). This report may also be known as the F-1 Report.

Natural rubber is a unique biopolymer of strategic importance that, in many of its most significant applications, cannot be replaced by synthetic alternatives. The rubber tree Hevea brasiliensis is the almost exclusive commercial source of natural rubber currently and alternative crops should be developed for several reasons, including: a disease risk to the rubber tree that could potentially decimate current production, a predicted shortage of natural rubber supply, increasing allergic reactions to rubber obtained from the Brazilian rubber tree and a general shift towards renewables. This review summarizes our knowledge of plants that can serve as alternative sources of natural rubber, of rubber biosynthesis and the scientific gaps that must be filled to bring the alternative crops into production.
