The kara mandarin: Tangerine-type, late spring fruit of excellent eating considquality is promising
by James W. Cameron, Robert K. Soost
| Full text HTML  | PDF  
Not available – first paragraph follows: The Kara mandarin is a tangerine-type citrus fruit, which was first described in 1935. Its parents were the Satsuma mandarin and the King-probably a tangor. Because of its high quality, additional studies were made in 1952 on the behavior of the Kara.

Cucumber beetles: Insecticides tested for control on melons in northern California
by A. E. Michelbacher, W. W. Middlekauff, O. G. Bacon
| Full text HTML  | PDF  
Not available – first paragraph follows: Melon fields—if left unprotected from the cucumber beetle—are likely to be damaged and some will be completely destroyed.

Nutrient units per dollar: Purchase of food by nutrient content per pound more efficient than by cost per pound
by John H. MacGillivray
| Full text HTML  | PDF  
Not available – first paragraph follows: Foods vary in nutritional value and in price and—when not controlled by taste preferences—their purchase usually is for nutrient content. But because most foods contain seven or more essential nutrients appraisal is difficult without some sort of guide.

Dormancy of grasses: Temperature, day-length, available moisture factors on rang elands
by Horton M. Laude
| Full text HTML  | PDF  
Not available – first paragraph follows: On California rangelands, the perennial pine bluegrass—Poa scabrella—may enter complete dormancy in late spring when surrounding annual vegetation is still green and vigorous.

Dryland pasture erosion control: Establishment of perennials for forage on sloping land needs minimum seedbed preparation and reduces erosion
by Bryan C. Sandlin, Victor P. Osterli
| Full text HTML  | PDF  
Not available – first paragraph follows: A good dryland pasture stand can be obtained on sloping or hilly range land with a minimum of seedbed preparation—and without undue loss of top-soil.

Pollen storage: High viability of pollen obtained after storage in home freezer
by W. H. Griggs, George H. Vansell, Ben T. Lwakiri
| Full text HTML  | PDF  
Not available – first paragraph follows: Hundreds of samples of deciduous fruit and olive pollen—used in breeding and artificial pollination studies—have been stored satisfactorily from one season to the next in an ordinary home freezer at temperatures ranging close to 0°F.

Sweet potatoes: Flowering induced by grafting scion on ornamental rootstock
by M. P. Zobel, G. C. Hanna
| Full text HTML  | PDF  
Not available – first paragraph follows: Most varieties of sweet potatoes— Ipomea batatas—normally do not produce flowers under California conditions. The ability to induce flower and seed production would greatly facilitate the development of varieties with superior quality, higher yield, and disease resistance.

Not available – first paragraph follows: The agromyzid leafminer—Liriomyza subpusilla Frost—was more abundant on tomato during the 1952 season than in any other recent year.
