Phenology, growth and yield of raspberries (Rubus idaeus L.) in response to two pruning methods

Phenology, growth and yield of raspberry, Heritage climbing variety show highly significant differences in response to two types of winter pruning: long pruning and ground level pruning, in tests carried out during three years under ecological conditions of San Luis Sierras (Argentina). With long pruning, there is a two-month advance in the appearance of flower buds and therefore, of ripe fruits; also, there is a higher total yield, since the number of gatherings is greater. With ground level pruning, shoot growth increases and fruit size is bigger. Thus, it is convenient to use both pruning systems in commercial cultivation, in order to regulate the harvest and the availability of skilled labor.
