"In order of production, I would rate the northern varieties as follows from highest to lowest: Major, Greenriver, Busseron, Indiana, Niblack, Kentucky, Warwick, Posey, Coy, Tissue, Johnson. Perhaps a little broader classification and grouping should be made. In my judgment, the Major, Greenriver, Busseron, Indiana, and Niblack compose one group which may be depended upon for fairly satisfactory production. The Kentucky, Warwick, Posey, Coy, Tissue, and Johnson have consistently been much lighter producers than those named in the first group.
"In order of desirability for planting I would make a list about as follows: Niblack, Major, Greenriver, Busseron, Indiana. I list the Niblack as first choice because it seems to be about as productive as any of the other varieties, and because of its excellence as a cracking nut and the quality of the kernel. The Niblack is really a very desirable nut for cracking, when it is cracked by such devices as the Squirrel cracker which applies pressure to both ends. The kernel comes free from the shell. In a good many varieties, such as the Indiana and Busseron the kernel and shell do not drop free, but the kernel frequently is wedged in furrows in the shell so that the two must be pulled apart. This is not true of the Niblack. When they are cracked by end to end crackers, the shell and kernel drop free. I list Major as second choice because of its good production. It is a little bit late in maturing for a variety of the northern group, and will sometimes get caught by frosts in many northern localities. The nut is not a desirable one for cracking because of its shape. A good cracking nut must be oval. The Major is comparatively round and many of the kernels will be crushed when they are cracked. The Greenriver is a good producer but it is a little bit late. The Indiana and Busseron are both proved to be good producers.
"Comparing the general production of the northern varieties and the southern varieties, as groups, the northern varieties seem never to be so productive in Oklahoma as are the southern varieties. Much more dependable production may be obtained from the southern varieties.
"Some data on cracking percentage of nuts and size of nuts might be desirable. This list is not complete, but contains several different varieties.
