"Great variations occur in the yields from Rotundifolia vines. At times there are record-breaking yields and, again, small yields are reported, the small yields resulting from black-rot, coulure, wet weather, self-sterility, lack of cultivation, fertilization, lack of pruning, age of vines, and various other causes. In spite of this, Rotundifolia vines are said to be among the safest and most prolific of fruit-bearing plants. While in one of the largest Rotundifolia vineyards there has been only a partial crop during the last three years, owing to various causes, another grower reports a yield of 177 bushels of grapes from 4-year-old James vines, in addition to a bale of cotton to the acre. A Florida grower estimated his crop of white Rotundifolia and Thomas grapes for the season of 1911 at 280 bushels to the acre. An average yield of 27 bushels an acre from 4-year-old vines, 100 bushels from 5-year-old vines, and 150 bushels to the acre when the vines are in full bearing should be obtained. "The prices paid for Rotundifolia grapes depend on the season, the quality of fruit, and the market. In years when the crop is short better prices are usually paid than when there is a heavy crop. Aside from the grapes sold and shipped to wineries, grapes as a rule sell for more in the cities and larger towns than in smaller places, the local demand being somewhat in proportion to the population. In such localities fruit of good quality will bring a much better price than inferior fruit. Hand-picked fruit in half-bushel peach baskets or in berry boxes usually brings from $1 to $2 per bushel. Grapes harvested by jarring are usually sent to the wineries and bring an average of 75 cents per bushel of 60 pounds. The highest price paid for this quality of fruit was reached in 1910, when $2.25 per bushel (f.o.b. shipping point) was paid for white Rotundifolia. "In many localities certain growers have built up quite a reputation for themselves in choice, hand-picked fruit, which they ship to special customers in distant markets. For this purpose the James variety is usually grown because the berries adhere well and are of good size and flavor. Several growers ship as far north as New York and Boston, getting from $2.00 to $2.50 gross per bushel crate. In shipping, three styles of carriers are used--the 24-box strawberry crate, the 6-basket peach crate, and the 8-pound basket. More attention should be given to this phase of the industry. The varieties best suited for shipping are the James, Memory, Flowers, and Mish.
