Sugar beet: An efficient user of soil nitrogen
by F. Jack Hills, Gary R. Peterson
| Full text HTML  | PDF  
New measuring techniques have enabled researchers to accurately estimate the amount of N to apply to achieve maximum sugar yield.The efficient use of nitrogen fertilizer for sugarbeets calls for just enough to achieve maximum sugar yield, and no more. Experiments indicate that a t the correct application rate, excess N is not left to leach to ground waters.
Parasitic nematode seeks out navel orangeworm in almond orchards
by James E. Lindegren, Charles E. Curtis, George O. Poinar
| Full text HTML  | PDF  
Because the orangeworm-infested almond is not penetrable by most insecticides, a better solution to NOW infestation might be a biological control method. application of an entomophagous nematode.A strain of nematode used as a biological insecticide on a variety of crops has found new application as a biological control agent of NOW in almond orchards.
Effects of prolonged drying and harvest delay following ethephon on walnut kernel quality
by George S. Sibbett, George C. Martin, T. Mark Draper
| Full text HTML  | PDF  
Walnut kernel quality deteriorates if harvest is delayed. Ethephon, applied to advance harvest, was not found to accelerate this process.
Avoiding ethylene concentrations in harvested lettuce
by Leonard L. Morris, Adel A. Kader, James A. Klaustermeyer, Charles C. Cheyney
| Full text HTML  | PDF  
At almost any stage of the handling process, lettuce may be exposed to ethylene gas, trace amounts of which can cause russet spotting.A common atmospheric pollutant, ethylene gas, can result in serious quality losses in lettuce. Exposure can occur anywhere in the handling process.
Furadan controls root weevil on strawberries
by Norman F. McCalley, Norman C. Welch
| Full text HTML  | PDF  
When applied as a bed sprag to weevil-infested strawberry plants after fall and winter picking, Furadan greatlg reduced populations of woods and cribrate weevils.Experiments conducted over two years showed Furadan sprays can give effective control of woods weevil and cribrate weevil on strawberries.
Control of Penicillium decay of garlic
by Arthur S. Greathead
