The importance of climate on the raising of a bumper crop of sugar beets is being studied in controlled climate experiments in the laboratory.

Orangeworm is the term used for the larvae or caterpillars of several species of small moths damaging citrus in certain areas of southern California.

A spore-forming bacterium–Bacillus thuringiensis Berliner–successfully reduced populations of the alfalfa caterpillar to below the economic level in field tests near Dos Palos.

Nitrogen fertilizer bills for citrus in California can be reduced by application of frequent small doses of nitrogen to the irrigation water, use of low head sprinkler irrigation, noncultivation, and making neutral and alkaline soils slightly more acid.

Surging can' be minimized in future designs in the open system of concrete pipe irrigation but the closed and semi-closed types–where surging is no problem–have much to offer.

Heavy nitrogen fertilization of cantaloupes does not lessen the severity of infection caused by the mosaic virus, nor does it increase the yield of marketable fruit. It increases cantaloupe size and reduces the number of culled fruit.

Mastitis in dairy herds can be significantly reduced by proper management.

Deciduous ripe fruit character in peppers, which allows the fruit to be picked while the stem remains on the plant, was inherited in a cross of a tiny fruited Chili Piquin with large but non-deciduous varieties.

The fourth of five articles reporting the findings in investigations in the effectiveness, the safety and the cost of the use of controlled burning as a tool for land clearing.s No attempt is made to provide one formula for prescribed burning in California; each fire is an individual case to be planned on the ground.
