Abstract

Fertilizer experiments–and a nutrient survey during the 1958 spring season–showed that some fields in Kern and Tulare counties are being depleted of exchangeable soil potassium to the point of deficiency, through frequent cropping to potatoes.

State's irrigation districts: Segment of California's agricultural economy increasing in importance as changes in the water payment complex evolve

Processing limas for freezing: Unit costs drop rapidly as percentage of grade-out drops and as total volume and effective utilization of plant increase

Traffic-induced compaction: Inexpensive and relatively easy to use new soil penetrometer enables measurement of variations in degree of compaction

Reduction of wildfire hazard: Removal of dead fuel reduced damage by wildfire in treated portion of experimental second growth ponderosa pine range

Lygus bug control in alfalfa: Increasing tolerance to insecticides complicates control of lygus bugs in state's major alfalfa seed producing areas

Pests of field beans: Insect and mite damage to pink, red beans investigated in Sutter Basin area

California red scale parasites: Colonization and recovery of three species introduced from the Orient in 1956–1957 indicate establishment in California

Control of tomato leaf miners: Comparative field tests indicate Dylox and Diazinon may be suitable as replacements for parathion in control programs

Quality of brussels sprouts: Low temperatures during handling operations retarded quality deterioration in study of temperature effects on respiration
