Rye (Secale cereale L.) and wheat (Triticum aestivum L.) were overseeded in a soybean (Glycine max (L.) Merrill) crop on both Coastal Plain and Piedmont soils. This method of seeding enables the small grain crop to be planted at an optimum time rather than being subjected to a possible delay in planting caused by a late soybean harvest and/or wet fields. Rye and wheat grain yields were 53 and 75% higher, respectively, for overseeding than for late plantings.

Examples of specialized planting arrangements that can be easily and precisely planted by the use of watersoluble tape: (1) spacing between seed samples was 5.0 cm, and each sample can be a different genotype; (2) diameter of circle of seeds was 7.5 cm, and resulting seedlings in center of circle were measured for competitive ability with genotype in circle; and (3) seeds were 1.0 cm apart, with tape attached to a wire-mesh screen to facilitate planting and harvesting. T conventional method of planting smal grain crops after soybeans (Glycine max (L.) Merrill ) has been to prepar e a seedbe d by plowing and/or disking followed by seeding with a grain drill . Delays in seeding the smal grain crop are often encountere d because the soybean variety used matures later than the optimum planting date for smal grain. Wet fields may also prevent the soybean crop from being harvested on time, which wil l delay preparation of the smal grain seedbed . The practice of over&eeding rye (Secale cereale L.) in soybean fields has been used successfull y by a num ber of livestock producer s to provide a source of win ter grazing. These producers , located in coastal areas where soil moisture and humidity are high, have been successfu l in obtaining desirabl e stands of rye and Paper Number 136 of the Journal Series of the North Caro lina State University Agricultural Extension Service, Raleigh.
