Alphabetically-arranged entries present directions for growing a wide variety of vegetables organically.

Describes modern methods of growing food and discusses the importance of further technical development to preserve and produce more food for a growing world population.

Traced observations were carried out for efficiency and behavior of Camellia japonica L. in bloom stage by employing p** (32)-labeled phosphorus, growing in Southern Korea. The precentage of phosphorus contained in flowerbud was double the value of the other parts, and the root and the stem were the same patterns in the course of the times. The circulation of the phosphorus in the plant seems to occur within 4 hours, the proportions of the phosphorus at the growing-point and flowerbud had a half of the total phosphorus contained in other parts. Specific activities of each part were notable on the growing-point where, after 21 hours it took more than 80 %. On the other hand, the efficiency rate which derived from the phosphorus was shown as about 19 %

"Growing hardwood trees for pulpwood offers an opportunity to overcome the objections which woodland owners have to managing their timber. Pulpwood growing is a relatively short-term venture requiring minimum investments of time, capital, and technical know-how. Also, hardwood pulpwood is likely to have reliable local market outlets in southeastern Ohio for years to come. From 1960 to 1965 pulpwood production in the area has increased about 5 percent per year (Kingsley and Dickson 1967). The demand should continue to rise as pulpmills expand their productive capacities.S3.

The daily soil temperatures used in this light chamber study were patterned after observations made under field conditions: 18 to 39C where the surface was sparsely shaded by brush, and 18 to 53C where the surface was left bare. The soil moisture was maintained at field capacity. Emergence of sacaton (Munro), vine mesquite (HBK.), bush muhly (Scribn.), and fourwing saltbush ((Pursh) Nutt.) was adversely affected by the high temperature regime. Survival of all 14 accessions except rhodesgrass (Kunth), ‘Vaughn’ sideoats grama ((Michx.) Torr.), and black grama ((Torr.) Torr.) was reduced by the high temperature regime.At the close of the 21-day trial most species had stopped growing or were growing very slowly under the high temperature regime. The shoot weights for the plants growing in the low temperature regime averaged nearly twice as much as those growing in the high temperature regime. There was no significant difference in root weight per seedling between temperature regimes. The root lengths of black grama, ‘Vaughn’ sideoats grama, tobosa ((Buckl.) Benth.), lehmann lovegrass (Nees), and alkali sacaton ((Torr.) Torr.) were not reduced significantly by the high temperature regime.The high temperatures were detrimental, in one way or another, to all species even when moisture was adequate but black grama and sideoats grama performed satisfactorily.
