Several of 60-odd rootstocks used in an extensive citrus rootstock trial of the Citrus Experiment Station at Riverside exerted a dwarfing effect on scions budded onto them.

Field-plot measurements of the effect of 2,4-D and related compounds on fruit drop, fruit production, and leaf drop of Eureka lemon trees were made on eight experimental field plots.

The injection method of supplying nutrient elements to trees was chosen at the outset of a study as to whether citrus trees would respond to potassium applications.

Field investigations with different spray methods have shown that heavy applications—1,100 gallons per acre on average sized trees, to 2,500 gallons on larger trees—are not necessary to obtain satisfactory deposits...
