Quality and care of men's shirts
by Harriet H. Prato, Mary Ann Morris
Price may be a poor criterion in judging the performance of garments: lower-priced shirts surpass higher-priced shirts in durability and color-fastness.
Grazing mixed conifer forests
by Barbara H. Kosco, James W. Bartolome
Grazing on the 13 million acres of mixed conifer forests in California could provide an income through grazing fees, reduce fire hazard, and enhance tree growth—while providing more efficient livestock production for foothill ranches.The heterogeneous mixture of forage in mixed conifer forests can be well-utilized by grazing cattle throughout the year, particularly if herds are evenly distributed in the forests.
Eutypa fungus causes grapevine dieback
by Amand N. Kasimatis, William J. Moller
It has been shown conclusively that a grapevine dieback disease is caused by the wound pathogen Eutypa ameniacae.
Impact of now insecticides on mites in northern California almonds
by Marjorie A. Hoy, Norman W. Ross, Don Rough
The use of NOW insecticides in northern California almond orchards can increase pest mite populations significantly.
Effectiveness of Osmocote fertilizer influenced by placement and dosage
by Ruth A. Coleman, Tom Mock, Tok Furuta
Irrigation system, irrigation frequency, and use of supplemental fertilizer determine the effectiveness of controlled-release fertilizer for the culture of plants in containers.
Chemical control of seed-borne diseases of wheat and barley
by Dennis H. Hall, Beth L. Teviotdale, Albert O. Paulus
When alkyl mercury compounds were prohibited as treatment for seed-born jdiseases of cereals, tests were begun to find effective controls that do not contain mecuryTests of more than fifty chemicals clearly demonstrated that seedborne disease of winter cereals can be effectively controlled with compounds that do not contain mercury.
Environmental influences on corn hybrids
by John D. Prato, Jack P. Orr, Franz R. Kegel, Thomas E. Kearney, Everett F. Nourse
Single- and three-way-cross hybrids, and differences in soil types and climate, have made single-environment testing of corn hybrids inapplicable for variety evaluation. Growers must test varieties under their own growing conditions before making selections.Individual growers must carefully evaluate varieties under their own growing conditions before making selections of corn varieties.
Effects of basket design on cooling and holding strawberries
by Frank G. Mitchell, Gene Maver
Strawberries packed in solid-molded baskets take slightly longer to cool than those stored in open-mesh baskets. However, increased moisture condensation in solid baskets does not affect incidence of fruit rot.
Irrigating new avocado orchards
by Albert W. Marsh, Roy L. Branson, Sterling Davis, C. Don Gustafson, Ralph A. Strohman
Efficient water application depends on precise knowledge of water needs and use by trees.Trials on Haas and Reed avocados determined monthly water requirements of drip- and sprinkler-irrigated orchards.In a study of young avocado orchards, water requirements in both drip- and sprinkler-irrigated fields were recorded.
Prompt handling reduces processing-tomato losses
by Adel A. Kader, Leonard L. Morris
Mechanical damage to tomatoes during harvesting and handling is an obvious cause of losses, but delays in delivery and processing may cause additional losses in quality.
Pinching azaleas chemically
by James R. Breece, Tok Furuta, Henry Z. Hield
