Light fruit set and leaf injury from boron deficiency in vineyards readily corrected when identified
by James A. Cook, Bruce E. Bearden, C. Verner Carlson, Carl J. Hansen
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Excess boron in the soil of some grape growing regions of California has caused vine injury in many vineyards and the possibility of boron deficiency has received little attention until recently.

Studies on self- and cross-pollination of olives under varying temperature conditions
by Muriel V. Bradle, William H. Griggs, Hudson T. Hartmann
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Investigations with Ascolano, Manzanillo, and Sevillano olive varieties show that chances of fertilization and fruit set are much greater after cross-pollination than after self-pollination. Pollen tube growth usually is faster following cross-pollination than after self-pollination and more pollen tubes can reach embryo sacs before the sacs degenerate.

Shipping methods used for fresh cut flowers evaluated in transcontinental trials
by Seward T. Besemer

Summary Not Available – First paragraph follows: Six trial shipments of cut flowers grown in San Diego County were sent by air freight to Ithaca, New York, to evaluate the condition of the flowers on and following arrival at the eastern market.

Surface irrigation water deliveries and costs in the San Joaquin Valley cotton area
by Charles V. Moore, Trimble R. Hedges
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Most San Joaquin Valley operators of irrigated farms depend on surface water sources to supplement ground water supplies. In years of low rainfall, when ground water levels drop, wells deliver less than normal quantities—some wells go dry—and sources of surface water are of increased importance.

Effects of tillage and fertilizers on use of water and soil salinity in irrigated orange orchard at Riverside
by Robert B. Harding, Thomas M. Ryan
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Where furrow irrigation is practiced there is extreme variability in concentrations of soluble salts in the soil, and the effects of cultural practices and different fertilizers determine the distribution of the salts.

Test crop on acid soil indicates manganese toxicity may be aggravated by nitrogen
by John C. Lingle, J. R. Wight
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Heavy application of ammoniacal nitrogen fertilizers to acid coastal soils has been suspected of stimulating manganese toxicity of Brussels sprouts.

Feeding trials with dairy cows show DDT detectable in milk is proportional to DDT in daily feed
by G. Zweig, L. M. Smith, S. A. Peoples
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: A feeding experiment with dairy cows was conducted in an attempt to define a level of DDT in feeds that would be un-detectable in the milk. For six weeks pairs of animals—including producers of both high- and low-fat milks—were fed daily rations containing 0-5 ppm—parts per million—of DDT, based on their feed intake.

Low-concentrate rations for fattening lambs tested in two feeding trials
by J. H. Meyer, A. O. Nelson
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The fattening of lambs on a low-roughage ration was studied in two experiments to determine whether sheep as cattle can be fattened on rations with low-fiber content.
