RESULTS OF SEED TESTS 

 Made July 1, 1930, to June 30, 1931 



This report contains the results of the inspection for the 

 State Department of Agriculture of three hundred eighty- 

 five official samples collected throughout the State during 

 the period from July 1, 1930, to June 30, 1931. These were 

 analyzed and the results mailed to the retail dealers. In 

 addition to these official samples, fifty-two private samples 

 were analyzed, making a total of four hundred thirty-seven 

 samples inspected. 



The seed law does not prohibit the sale of poor seed but 

 it does require that all seed be labelled to show its quality. 

 The buyer is therefore protected. The purpose of the seed 

 inspection work is to determine, within reasonable limits, 

 whether a sample of seed is as good as it is guaranteed 

 to be. 



A certain amount of variation is to be expected in com- 

 paring the results of two or more purity anaylses. For this 

 reason a "tolerance" or variation is allowed in accordance 

 with the following formula, applied to the guarantee given. 

 The sample is considered as being made up of two parts, 

 the one being the pure seed and the other the balance of the 

 sample. The tolerance in per cent allowed for each part is 

 two-tenths of 1 per cent plus 20 per cent of the lesser part. 

 For instance, if a sample is guaranteed 99.60% pure seed, 

 it may test as low as 99.32% or as high as 99.88% and 

 would be "satisfactory." In the same way, a sample guar- 

 anteed 92.80% may test as low as 91.17% or as high as 

 94.43% and be "satisfactory." If a sample is found to be 

 better than the highest figure in the tolerance, it is marked 

 "A-bove" in this bulletin; if lower than the lowest figure, 

 the actual figure is reported.
