G92-1071 Ridge Plant Systems: Weed Control

Advantages and disadvantages of the ridge plant system, weed control before and at planting and economics of the system are discussed. Ridge planting combines tillage and herbicides to achieve improved weed control in row crops. Crop seed is planted into ridges formed during cultivation and/or ditching of the previous crop. In ridge planting, the planter follows the old row and ridge clearing sweeps or disks move the surface soil, residue and much of the weed seed out of the row. Weed seeds are deposited between the rows where, upon germination, they can be controlled with cultivation. Two cultivations are generally used for weed control. The first cultivation loosens the soil and the second rebuilds the ridge. The ridge plant system is well suited to furrow-irrigationd crops. It also works well with dryland crops or those under center pivot irrigation. On furrow irrigationd land, corn or sorghum stalks may need to be shredded to assist in decomposition and hence irrigation because crop residue slows water advance in the furrow. Slowing the water may be a benefit, however, on soils which have a low water intake rate. With center pivot and dryland acres the need for shredding depends on how much residue the cultivator can handle

G76-294 Band Application of Herbicides (Revised March 1986)

Many row crop producers prefer to use hebicide band applications because of reduced costs. Savings can be substantial with the more expensive materials. Properly applied, band applications of herbicides can satisfactorily protect the crop from weed growth. Herbicide row banding can be done either at crop planting time or postemergence after the crop and weeds have emerged

INSECT, PLANT DISEASE, & WEED SCIENCE NEWS [No. 87-5] [April 7, 1987]

In This Issue: -Weed Control Considerations on CRP Acres The Conservation Reserve Program is raising questions that many growers have not faced before. These questions relate to choice of permanent grass cover, how to get from an existing residue or crop into the permanent grass, what to do this year if grass seed is not available for planting the permanent cover, and probably many other situations. Some typical situations growers may face are discussed below, primarily from the viewpoint of weed control

G74-131 No-Till Corn in Alfalfa Sod

Nebraska produces about 1,740,000 acres of alfalfa annually. Corn or grain sorghum usually follows alfalfa in the crop rotation. The moldboard plow or chisel plow are commonly used to break up alfalfa sod for corn planting. The plow is a high consumer of energy, requiring about 2.25 gallons of diesel fuel per acre. Research conducted in Nebraska has been used to develop a system in which the alfalfa is killed with herbicides and corn is planted directly into the sod without tillage. Plowing is eliminated and energy requirements can be reduced to about 1/4 that used in the conventional plow system. This publication discusses how to accomplish planting corn using this method

G90-963 Narrow-row Soybeans

Narrow-row spacing of soybeans may be a profitable practice with modern herbicides and new lodging-resistant varieties. This NebGuide describes considerations for producing narrow-row soybeans. Early in this century crop row spacing was determined by the breadth of the animals used to work the fields. Spacing had an impact on methods of weed control and the varieties of soybeans developed. Even a decade ago row spacing was determined by tractor tire size since cultivation was required. Also, the tall varieties of soybeans lodged severely in narrow-row systems. However, the broad spectrum of herbicides now available and lodging-resistant soybean varieties have made narrow-row soybeans more practical. Narrowing soybean row spacing can increase yields if light utilization is the yield-limiting factor. The main purpose of narrow rows is to intercept more light. Unlike fertilizers and water which can use the soil as a reservoir, light falling on bare soil cannot be used. Decreasing row spacing results in more rapid canopy closure and increased light interception. Canopy closure at or shortly after flowering will maximize yields in ideal conditions. However, Nebraska\u27s growing seasons are rarely ideal. Any yield limiting factor like lodging, weed growth, moisture stress, soil compaction, high soil pH, or nutrient deficiency will reduce soybean yield responses in narrow rows
