Abstract
On December 3, 1974 our Chief Executive wrote to the President of the National Academy of Sciences and to the Secretary of Agriculture calling for an assessment of the food problem. A program with research and development recommendations to insure our food supply and improve nutrition for ourselves and other nations was requested. Priorities were to be set, specific programs outlined, and needed resources determined. A report is now available (2).
Abstract
Phosphorus occupies a unique position in the nutrition of horticultural crops. The net quantitative plant needs are not as great as for the other macro-nutrients. Crop removal is usually only a fraction of that for N, K, or Ca. Large quantities applied as fertilizer to the soil may revert to, or become fixed in, unavailable forms. There may be little movement from the area of placement. Although present in the soil it can be positionally unavailable. Seeded row crops and vegetable, strawberry, and flower transplants may show a marked response to applications of this nutrient in early spring but nothing later on.
Abstract
A brief review of a number of growth regulator responses, applications and recent discoveries of likely interest to horticulturists.
Abstract
I first met Bob Carolus 30 years ago at an annual ASHS meeting at St. Louis. Bob had just moved to the then Michigan State College to head up the vegetable program in teaching and research in the Department of Horticulture. As usual, he was promoting something new. This time it was prepackaging of fresh produce for protection and preservation. He had a special meeting and displayed samples – some of the first examples I’d ever seen of plastics – plastics for prepackaging. A package you could see through. There was also stretch film. I was fascinated. Each subsequent contact with him has been stimulating, invigorating, enlightening, and encouraging. Bob Carolus never lacks for vision and ideas.
Abstract
Agricultural research, technology, and development is at a crossroads in this nation. The chart ahead is not clear. If food is important, it’s not reflected by current investments in research. Food has been taken for granted. The present affluence of our nation in the adequacy, safety, and variety of its food supply exceeds that of any known people that have ever inhabited the earth.
Abstract
Dramatic increases have recently occurred in the productivity of the major food crops (rice, wheat, corn, grain sorghum, potatoes). These advancements have characterized a worldwide “green revolution” and received much publicity (2). An equally remarkable and parallel record of production efficiency, accompanied by an enhancement of quality, has also occurred with most fruits and vegetables (7). Many of these remarkable changes have transpired where as an increasingly greater percentage of the commodity is being utilized in the processed form.
Abstract
Members of this Society, individually and collectively, face some crucial decisions in public relations. The title of this paper should convey a message. The American public (taxpayers) are resisting further increases in support of education and agricultural research. There is an expression of disenchantment. Our operations are now being scrutinized as never before. If improvement is to occur it must come from new approaches rather than from more of the same.
