USE OF LISTER 175 



which has not been previously disced and loosened, but rolls up in 

 lumps, will also do the same thing. 



On many large areas a combined riding lister is used; that is, a 

 drill attachment at the rear of the lister drops the corn and two small 

 shovels or discs cover the kernels. For doing very uniform work, 

 through all kinds of soils, this lister is the best implement, especially 

 on level land. A walking lister may also have this combined attach- 

 ment. Often the lister is drawn alone and the drilling is done with 

 a one-horse drill, or a two-row planter is used. A planter does not 

 follow the listed furrows uniformly unless they have been turned with 

 a two-row lister. The kernels are often dropped on the edge of the 

 furrow, which gives the young plants insufficient root hold, besides 

 making them hard to cultivate. 



Checking can be efficiently done in listed furrows, but the corn it 

 usually not large enough to cultivate crosswise at the second plow- 

 ing. Corn may be listed in ground already prepared for surface check- 

 ing, but in such a case the soil is usually so loose that the lister will 

 not scour satisfactorily. Stubble land is often listed with good re- 

 sults. In listing ground which has been in corn the previous year, 

 either the old row may be listed out or the furrow may be made 

 between the rows. Double listing — listing once early and then relist- 

 ing the ridge later in the season — is a more efifective way of loosen 

 ing up the soil. 



The furrow-opener attachment is rapidly gaining recognition, espe 

 cially in those districts where the corn must be planted deep in order 

 to better resist the drouth and wind. In many localities it is gradu- 

 ally replacing the lister. The ground is plowed and the seed bed pat 

 in proper condition by use of the disc and the harrow. An ordinary 

 corn planter is then used with the furrow opener attachment. The 

 corn is thus planted at a sufficient depth and may be either drilled or 

 checked. This permits of a much more thorough preparation of the 

 seed bed, giving the corn plant the advantage of an earlier start. With 

 the use of the furrow opener attachment, the Kansas Experiment Sta- 

 tion has been receiving very satisfactory results.
