Border rows of oat plats as affecting yields and variability
1934
McClelland, C.K.
It is clearly shown that the inclusion of border rows in plat yields when exact areas are considered gives an exaggerated yield, varying from about 4 to 8% from that obtained from interior rows, with higher percentages when wider alleys accompany narrow plats. The yield of first borders showed increases varying from 18.4 to 54.0%, the larger increases being due to wider alleys. The yields of second borders showed variations from -- 5.2 to 8% and were significant in only one case, that with 8-inch alleys in 1930. The inclusion of the alley area with the occupied area changes the yields as determined from all rows from an exaggerated yield into one usually significantly below that obtained from the interior rows. Inclusion of border rows of variety tests of winter grain caused greater variability than in tests where but one variety was concerned. There was less difference with spring oats varieties. The use of wide alleys caused greater variation in the first border rows and added to the inaccuracy of the results. The data are of value as an indication of the accuracy of the work in cases where insufficient help is available to harvest border rows.
