Influence of soil type on the yield and quality of pecans

The data given in the foregoing tables are from orchards where the factors, except the soil, are similar. In each case presented, it appears fair to conclude that the differences in yield, size, and quality of the nuts are due to the soil. Schley pecans produced better yields and a larger nut on Orangeburg sandy loam than on Norfolk sandy loam at Putney, Georgia. There was very little difference in the percentage of meat, oil and protein content of the meat, from the nuts grown on the two soils. Alleys produced larger yields and a larger nut on Greenville sandy loam than on the Norfolk sandy loam at Putney, Georgia. Stuarts produced larger yields on Orangeburg sandy loam than on Ruston sandy loam at Putney, Georgia. The size, percentage of meat and protein content of the meat, were practically the same in the nuts grown on the two soils. The oil content of the kernel was slightly higher in the nut from the Orangeburg soil. Frotschers produced larger yields on the Greenville sandy loam and Norfolk sandy loam than on the Susquehanna sandy loam at Cairo, Georgia. The nuts were larger, better filled, and contained a higher oil and protein content on the two former types than on the latter. There was practically no difference between the yield and quality of the nut grown on the Greenville and Norfolk soil, the slight difference which prevailed was in favor of the Greenville soil. Money Makers produced larger yields, larger and better filled nuts of a higher oil and protein content on the Greenville sandy loam and the Norfolk sandy loam than on the Susquehanna sandy loam at Cairo, Georgia. There was practically no difference in the nuts from the Norfolk and Greenville soil. Schleys produced larger yields and larger and better filled nuts on Greenville sandy loam than on Orangeburg sandy loam at Robertsdale, Alabama. The oil, protein, and sugar content of the kernel were practically the same in the nuts, grown on the two soil types.
