How to grow successfully broccoli, brussels sprouts, cabbage, cauliflower, and kohlrabi.
Cole crops, which include broccoli, brussels sprouts, cabbage, cauliflower, and kohlrabi, can be successfully grown on most soils if drainage is good and the crop is supplied with adequate water and nutrients, particularly nitrogen. Light-textured soils usually produce earlier crops but heavier soils hold more moisture and tend to produce crops that hold quality longer at maturity.
Cole crops have shallow root systems. Inadequate moisture may cause small cauliflower heads to form prematurely. Rainfall or irrigation following a prolonged dry spell may cause splitting of cabbage and kohlrabi. Supplemental …

Characteristics of soil-applied herbicides are discussed, including site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. For best performance, preemergence and preplant herbicides must be placed in the top 0 to 3 inches of soil. Placement is important because the herbicide must enter the germinating weed seedling in order to kill it. Herbicides can be blended into the soil by mechanical incorporation, rainfall, or sprinkler irrigation, depending on the herbicide. Herbicide characteristics that determine their performance are site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. An understanding of these factors will …

This publication describes a technique used to evaluate the relative performance of insecticides in protecting corn roots from feeding damage by corn rootworm larvae.
Insecticides applied at planting or cultivation time are commonly used in continuous corn to protect the roots from damage by western and northern corn rootworms.
Measuring the relative performance of these insecticides in protecting corn roots from rootworm larval damage is important.
