Abstract
Leaf symptoms of K deficiency in grapes were described as early as 1894, but this nutritional disorder was not identified in deciduous fruits until 1928. It is the most common nutritional problem of grapes and all other deciduous fruits require K fertilization under certain soil conditions. Potassium deficiency is frequent on light, sandy soils low in K, on heavy soils with a high fixing power, and on calcareous soils. On susceptible soils, it is often associated with heavy production.
Abstract
I consider myself to be a geneticist and plant breeder. Although not an expert in nutrition, I have long been interested in the improvement of nutritional value through plant breeding. This interest has led to a study of the genetic control of carotene synthesis. This knowledge has been used in our breeding program to derive tomatoes with a high content of provitamin A, and to the improvement of color.

, from plants, garden-based curriculum may be an effective way to teach nutrition ( Morris and Zindenberg-Cherr, 2002 ). Schools play a critical role in nutrition education not only to encourage physical health of students but also to increase educational

Abstract
The review by Evans and Sorger (6) on “The Role of Mineral Elements with Emphasis on the Univalent Cations” as found in the 1966 Annual Review of Plant Physiology Volume 17 is principally concerned with other than floriculture crops. However, the K nutritional requirements of floriculture crops are so similar to those of vegetables that the review can stand for both.

Abstract
In discussing the nutrient components of foods there is often a tendency to discuss those that receive the most positive emphasis by nutritionists. Proteins, vitamins, and even minerals far too often receive the major emphasis. However, the availability of calories, closely related to the availability of food, is often ignored, particularly in discussions of world malnutrition. The presentations delineate the massive population increase, and then suggest the solution to be a technical advance that will increase the amount of protein available. But the basic problem is food, and in order to establish some priority it must be recognized that the availability of calories is one of the first limiting problems in world nutrition. This does not suggest that the distribution of protein to various segments of a population is not important.
