Orchard 1, with trees in 1927 equivalent to 550 mature trees, used 2651/^. 1531/2 ai^d 498 hours respectively in the three years. The average of approximately 306 hours per season could be done by one man. Actually the operator has done most of the pruning alone. As shown above, the weighted average time on pruning was 567 hours per mature trees. If the time available per season were roughly 450 hours, one skilled man could expect to prune approxi- mately 800 mature trees per season by working at all available times. It is possible to use some unskilled help in pruning if the .skilled worker will designate the larger branches to be removed and supervise the 670 5 6 7 r^RM Number Fig. 7. Total man hours per season reqidred on each farm to spray 1,000 mature trees. The number of applications and degree of thoroughness varied from farm to farm. Spraying requires a considerable degree of skill, and the work must be done at very definite periods. Competent men cannot be secured on short notice, and consequently the whole farm organization usually centers about the spraying operation. Either the operator must diversify to pro- vide productive employment for the spraying crew in slack orchard periods, or he must contrive, as by the use of dusting, to get the work done within the necessary time limits without keeping a large crew. In view of these facts, improvements in the efficiency of spraying as by the adoption of nozzles of large capacity, or improvement in the facilities for mixing materials and refilling the tank constitute a very great economy in the whole orchard program. work of the unskilled men in addition to his own pruning. In this way, with some unskilled help, a skilled fruit man could tprune 1,000 mature trees per season. SPRAYING Spraying represents the mo
