Abstract

The potato defect—internal black spot—involving the variety Netted Gem in the Santa Maria Valley is of considerable economic importance.

Also in this issue:

Mechanical cotton harvesters: Acreage controls, changes in cultural practices and prices affect economics of machine harvesting on individual farms

Machinery for soil drainage: Comparative analyses made of production volumes of various earthmoving machinery used for preparing land for drainage

Zinc deficiency in the avocado: Application of zinc chelates to soils may solve the zinc problem in trees on land too steep for spray rig operation

Fertilizers for timber trees: Exploratory greenhouse investigations show varying responses of timber trees to soils and to applications of fertilizers

Maleic hydrazide tested on ivy: Growth inhibitor applied by foliar sprays maintained ground and fence covers of ivy for an entire summer without pruning

Potato fertilization and internal black spot in Santa Maria Valley: Deficiency of important nutrient found to exist in soils of many potato fields during survey and fertilizer experiments

Meat in retail grocery stores: Availability of fresh meats, frozen meats, and cold cuts in stores surveyed influenced by store size, ownership, location

Vinegar fly control treatments: Effectiveness of insecticide formulations and of inert dust diluents assayed in laboratory studies using fruit crop pest

Water conduction from shallow water tables

Soil macrostructure as affected by cultural treatments
