Cottonseed Quality - 1983 Crop

:onseed from the 1983 crop was lower in grade than the previous season, according to the Cotton Division, Agricul- il Marketing Service, USDA. The average grade from the 1983 and 1981 crops was 96.0 and from the 1982 crop was . The quality index from the 1983 crop was 98.4, up from 98.0 in 1982 and 98.1 in 1981. Foreign matter content of 3 cottonseed was 1.6 percent, up from 1.4 percent the previous year and down from 2.0 percent two years ago. ture content of cottonseed from the 1983 crop, at 11.0 percent, was the highest for any crop since 1974 and was up - 10.9 percent a year earlier and 10.1 percent two years ago. Free fatty acids content, at 0.7 percent, was the st since the 1976 crop and was down from 1.1 percent in 1982 and 0.8 percent in 1981. The quantity index of onseed from the 1983 crop was 97.12, the lowest since records were established in 1944. Quantity index of 1982 onseed was 98.22 and for the 1981 cottonseed was 97.69. Average oil content of 1983-crop seed was 17.0 percent, lowest since 1980 and down from 17.5 percent in 1982 and 17.2 percent in 1981. Average ammonia content was 4.02 ent, the highest since 1980 and up from 3.89 percent a year earlier and 3.97 percent in 1981.

cated 1983 cottonseed production is 3.08 million tons compared with 4.74 million a year earlier and 6.40 million in

from grade certificates covering 24,549 samples of cottonseed were used to compile this report. Averages of onseed quality and quantity factors and grades are shown by states (when sufficient certificates were received), by is and by specified frequencies. Average grade factors of cottonseed are shown by states in Table 3. The averages us table are arithmetic means of grade factors and indexes tabulated and averaged from the individual grade cer-Dates issued by chemists licensed by the U. S. Department of Agriculture.

summary of national averages appearing in Table 1 below and presented in other tables of this report is based on quality and quantity and grades weighted by the number of certificates received.

Standards for Grades of Cottonseed Sold or Offered for Sale for Crushing Purposes Within the United States

Determination of grade. The grade of cottonseed shall be determined from the analysis of samples, and it shall he the result, stated in the nearest whole or half number, obtained by multiplying a quantity index by a quality index and dividing the result by 100. The quantity index and the quality index shall be determined as hereinafter provided.

(a) The basis grade of cottonseed shall be grade 100. (b) High grades of cottonseed shall be those grades above 100. (c) Low grades of cottonseed shall be those grades below 100.

Determination of quantity index. The quantity index of cottonseed shall be determined as follows:

(a) For upland cottonseed the quantity index shall equal 4 times the percentage of oil plus 6 times the percentage of ammonia plus 5.

(b) For American Pima cottonseed the quantity index shall equal 4 times the per-centage of oil plus 6 times the percentage of ammonia minus 10.

Determination of quality index. The quality index of cottonseed shall be an index of puri-ty and scundness, and shall be determined as follows:

(a) Prime quality cottonseed. Cottonseed that by analysis contain not more than 1.0 percent of foreign matter, not more than 12.0 percent of moisture, and not more than 1.8 percent free fatty acids in the oil in the seed, shall be known as prime quality cottonseed and shall have quality index of 100.

(b) Below prime quality cottonseed. The quality index of cottonseed that by a-nalysis contain foreign matter, moisture, or free fatty acids in the oil in the seed, in excess of the percentage prescribed in (a) above shall be found by reducing the quality index of prime quality cottonseed as follows:

(1) Four-tenths of a unit for each 0.1 percent of free fatty acids in the oil in the seed in excess of 1.3 percent.

(2) One-tenth of a unit for each 0.1 percent of foreign matter in excess of 1.0 percent.

(3) One-tenth of a unit for each 0.1 percent of moisture in excess of 12.0 percent.

(c) Off quality cottonseed. Cottonseed that has been treated by either mechani-cal or chemical process other than the usual cleaning, drying and ginning (except sterilization required by United States Department of Agriculture for quarantine purposes) or that are fermented or hot, or that upon analysis are found to contain 12.5 percent or more of free fatty acids in the oil in the seed, or more than 10.0 percent of foreign matter, or more than 20.0 per-cent of moisture, or more than 25.0 percent of moisture and foreign matter combined, shall be designated as "off quality cottonseed".

(d) Below Grade cottonseed. Cottonseed the grade of which when calculated ac-cording to the foregoing is below grade 40.0 shall e designated as "Below Grade cottonseed" and a numerical grade shall be indicated.
