Planning public water projects: Economic principles involved in construction and operation have important bearing on over-all value of public projects
by J. W. Milliman
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Economic facets of water project planning—of primary importance in themselves—have important bearing on questions turning on legal issues of water rights and engineering questions of design, capacity, and location.

Weather pattern effect on corn: Relationship between weather extremes, silk distortion, and blanking in sweet corn indicated by Coachella Valley studies
by James W. Cameron, Donald A. Cole
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: A peculiar distortion of silk growth related to an unusual weather pattern was associated with severe and widespread blanking—failure of seed set—in early sweet corn in Coachella Valley in 1958. As a result, much corn harvested in various areas of the Valley during the first two weeks of May was discarded as cull. Later harvests were of much better quality.

Yellowing of garbanzo beans: Aphid-spread yellowing virus needs different control though visibly similar to Fusarium wilt caused by soil-borne fungus
by D. C. Erwin, W. C. Snyder

Summary Not Available – First paragraph follows: Garbanzo bean—Cicer arietinum—an edible crop grown in California in the south coastal areas, is ordinarily planted in April on nonirrigated land and harvested in July or August.

Mechanical pruning for citrus: Hedging and topping machines effective in increasing yields and reducing pruning costs during four years of field tests
by Paul W. Moore
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Annual pruning of mature, thrifty lemons with hedging and topping machines—supplemented by some hand pruning—is a means of cutting pruning cost by 30% to 50% without sacrificing either yield or fruit quality.

Sulfur deficiency widespread: Areas in 34 of California's 58 counties found to have soils deficient in nutrient essential for normal growth of plants
by W. E. Martin
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The frequency of sulfur deficiency in California soils ranks sulfur a close third—after nitrogen and phosphorus—as a major plant nutrient which must be supplied to maintain crop production.

Induced increase of soft scale: Imbalance between scales and natural enemies on walnut trees in northern California results in scale population increases
by A. E. Michelbacher, Stephen Hitchcock
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The principal natural enemies of soft scales attacking walnut trees in northern California are small winged parasites easily killed by trace amounts of insecticides. If undisturbed, the parasites are able to maintain the scale population much below an economic level.

Factors in prune skin texture: Marked skin toughness of dehydrated prunes investigated in effort to identify probable cause of the texture problem
by Leonora Hohl Strohmaier, Jane Magee Loomis

Summary Not Available – First paragraph follows: No direct relationship between thickness and toughness of the skins of dehydrated prunes could be found in studies of the thickness, structural and textural characteristics of four varieties of fresh and dehydrated California prunes.

Sweeter ice cream preferred: Study indicates consumers prefer ice cream with higher sugar content than the 15% level usually considered to be optimum
by Rose Marie Pangborn, Thomas A. Nickerson
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: An essential ingredient—sugar—affects palatability, body and texture, freezing point and storage properties of ice cream.
