IPM Japanese Beetle in ND

Integrated Pest Management of Japanese Beetle in North Dakota - E1631

The Japanese beetle, Popillia japonica Newman, belongs to the insect family Scarabaeidae. It is a highly destructive plant pest that feeds on more than 300 host plants, including field crops (especially corn and soybeans), ornamental trees and shrubs, garden flowers and vegetables, and turf (lawns, pastures and golf courses). Some of the preferred host plants of adult beetles found in North Dakota are rose, apple, black cherry, cherry, flowering crabapple, plum, grapes, hollyhock, blackberry, raspberry, linden, elm and buckeye. Grubs are found primarily in the root zones of grasses.

Sprinkler Irrigation Systems

Selecting a Sprinkler Irrigation System - AE91

The four basic methods of irrigation are: subsurface irrigation (“subirrigation,” which uses tile drain lines), surface or gravity irrigation, trickle irrigation (also called drip irrigation) and sprinkler irrigation. Of the acres currently irrigated in North Dakota, more than 80 percent use some type of sprinkler system. Statewide, the center pivot is the most popular sprinkler system.

Soybean

Soybean Growth and Management Quick Guide - A1174

Growth, development and yield of soybeans are a result of a variety’s genetic potential interacting with environmental and farming practices. Correct production decisions using plant growth staging and timing are important for successful soybean production. Minimizing environmental stress will optimize seed yield.

Soybean Variety Trial Results

North Dakota Soybean Variety Trial Results for 2014 and Selection Guide - A843

Soybean variety selection should be based on maturity, yield, seed quality, lodging, iron-deficiency chlorosis tolerance and disease reaction. Later-maturing varieties tend to yield more than early maturing varieties when evaluated at the same location. After determining a suitable maturity for the farm, comparing yields of varieties that are of similar maturity is important. Although late maturity increases yield potential, later-maturing cultivars are more risky to grow than earlier-maturing varieties because an early fall frost may kill a late-maturing variety before the beans have completely filled in the pods, which will reduce yield greatly.

Management Factors for Soybean Yield

Selected Management Factors for Economically Increasing Soybean Yield - A1718

Soybean yield increased with 14-inch versus 28-inch rows, 200,000 versus 150,000 pls/acre planting rate and special foliar inputs. The narrow rows also had higher net revenue than 28-inch rows. However, the low planting rate and no foliar inputs provided higher net revenue after costs of research factors versus the alternative choice for each factor.
