Abstract
The effects of three cultural practices to offset low winter rainfall were determined in 1977. 1) The removal of fruiting canes in a non-irrigated vineyard significantly reduced the cluster yield by 54% (p < .05) without affecting pruning weights. 2) Limited application of summer drip and sprinkler irrigation (2.4 acre-inches) gave significantly higher vine yield, cluster counts and berry weights than the control (p < .05). Pruning weights were increased in the sprinkler irrigated treatments only. 3) When winter irrigation was applied at a low (5 in), medium (10 in), and heavy (10 in winter + 5 ABSTRACT in summer) rate, vine yield, cluster weight, cluster counts, and berry weights increased significantly in the heaviest application (p < .05). The pruning data showed a similar increase.
Vineyard production was best accomplished by applying heavy amounts of winter irrigation. Limited summer drip and sprinkler irrigation was a successful means of vine maintenance, while the removal of fruiting canes was a poor method of managing non-irrigated vineyards.
