Sprinkling for heat control does no good on ten- der berries growing in wet spots 11* in too dense a vine growth. For beri-ies that are sound to start with, sprinkling helps. No agree- ment was reached on the practice of withholding irrigation water after a certain date to harden off the berries. It seemed undesirable to withhold water at any time. Berries should never be allowed to suffer from a lack of water even at harvest time it was agreed. The only real agreement in the field of fertilization was that each bog or part of a bog differed and should be handled accordingly. The following points were considered a good starting place in develop- ing a fertilizer program on indi- vidual bogs: (A) A maximum of 20 pounds pe.' acre actual nitrogen per sea- son. (B) The nitrogen should be used in fombination with both phosphate and potash. (C) It was felt that a 1-3-3 ratio of nitrogen phosphate and potash was best. A 3-10-10 or 6-20-20 was suggested a a good mixed fertilizer. (D) It was agreed a good starting point would be 200 to 300 pounds per acre of 3-10-10 or 100 to 150 lbs. per acre of 6-20-20. Picking dates would have to be moved up in most cases so that berries could be harvested before they got dead ripe to get good keeping quality. (A) It was felt that the average date would be around October 10-20 but that it would vary with the season. (B) It was agreed that a scientific test which is available, on the sugar; pectin ratio might be a good tool to use to determine pick- ing date. This would replace the inile of themb method used some now which says when the seeds are brown or the berries are 60 per- cent red they are ready to pick. (C) It was recognized that pick- ing early for fresh quality would generally result in some loss in total production.
