Almond variety evaluation
by Dale E. Kester, Warren C. Micke, Donald Rough, Dale Morrison, Robert Curtis
| Full text HTML  | PDF  
An index devised by University and almond industry experts shows the strong and weak points of eleven major varieties. Forty field andmarketing characteristics are rated.
Plant cover helps control rangeland soil erosion
by Michael J. Singer, John Blackard, Gordon L. Huntington
| Full text HTML  | PDF  
Range management to ensure adequate plant cover during the rainy season can prevent large erosion losses of foothill soils.
Mixing turfgrasses controls Fusarium blight
by Victor A. Gibeault, Richard Autio, Stanley Spaulding, Victor B. Youngner
| Full text HTML  | PDF  
Perennial ryegrass mixed with Kentucky bluegrass produces turf that looks good and resists Fusarium blight in hot summer months.
“Blue” soils cause complex drainage problems
by Blaine R. Hanson, Lynn D. Whittig
| Full text HTML  | PDF  
A shallow drainage system and careful irrigation management may be the only feasible solution when such soils underlie good top soil.Saturated “blue” soils drain poorly and hinder plant growth. When such soils underlie good top soil, the only feasible solution may be a shallow drainage system and good irrigation management.
Insecticides enhance spider mite reproduction
by Thomas F. Leigh, Paul F. Wynholds
| Full text HTML  | PDF  
Organophosphorus insecticides stimulated egg laying of mites reared on the treated cotton plants.Organophosphorus insecticides applied to cotton in greenhouse tests seemed to stimulate egg laying in mites reared on the plants. This and destruction of predators may explain some mite outbreaks.
Chemical “pruning” of walnut trees
by George C. Martin, Paul LaVine, G. Steven Sibbett, Chic Nishijima
| Full text HTML  | PDF  
A chemical pinching agent sprayed on young walnut trees in the spring reduced terminal growth and increased branching, producing a response similar to that obtained by pruning.
Irrigation rates critical in Imperial Valley alfalfa
by Frank E. Robinson
| Full text HTML  | PDF  
Applying too little water to Imperial Valley alfalfa in summer sprinkler irrigation causes leaf burn from salts in the water. Higher rates cause ponding and soil crusting.
New hope for Verticillium control in cotton
by Lee J. Ashworth, Oen C. Huisman
| Full text HTML  | PDF  
San Joaquin Valley cotton growers can now keep Verticillium wilt fungus levels low enough to obtain satisfactory yields by monitoring fungus buildup and rotating fields to other crops.
Combination of pear rootstocks recommended for new Bartlett plantings
by William H. Griggs, James A. Beutel, William O. Rell, Ben T. Iwakirl
| Full text HTML  | PDF  
Since no one type of Bartlett tree-with various rootstocks or own-rooted - proved superior in all characteristics studied over twelve years, researchers recommend a combination of the best types.
