It will be seen from the above tables that the average weight 

 of a bunch previous to trimming is approximately 3 lbs. (The 

 cuttings were weighed before bunching; as a result the yield in 

 pounds includes the weight of trimmings.) As the yield in pounds 

 and ounces of the sprayed and unsprayed rows was kept the 

 entire season, the total number of bunches obtained from the 

 sprayed and unsprayed rows can be estimated. It can be shown 

 from the first section of Table I, that 61.1 per ct. of the total 

 average number of bunches for the three cuttings on the un- 

 sprayed row are primes, also that 38.9 per ct. of these bunches 

 are culls; while from the second section it can be shown that 

 81 per ct. of the total average number of bunches for the three 

 cuttings on the sprayed row are primes, and the remaining 19 

 per ct. are culls. 



By first estimating the total number of bunches from the total 

 yield of each row, then from the total number of bunches esti- 

 mating the number of prime and cull bunches, and arranging 

 these in a table together with the total yield, the difference 

 between the sprayed and unsprayed row for th© entire season 

 will be as shown in Table II.
