Broadcast half of the total amount of fertilizer before rototilling to ensure fertilization throughout the root zone. Place the remaining half of the fertilizer at the center of the double rows. It is advisable to apply additional nitrogen in regions of heavy rainfall before the early summer growth decline period. Uniform, rapid growth produces quality carrots. Irrigation Commercial carrot production should not be attempted unless supplemental water is available by some reliable method.
Early moisture is the most important for carrot production.
Later irrigation should be timed to obtain maximum benefits from a sound chemical weed control program. Weed Control Chemical weed control is recommended for carrot grower's use. Carrot leaves grow slowly and are lacy. They are not able to compete with broad-leaved weeds or grasses or to shade them out. It is imperative that weed competition be eliminated.
