THE EFFECT OF MANAGEMENT SYSTEM ON WINTER SURVIVAL AND YIELD OF RASPBERRIES IN QUEBEC |
| Author: | D. J.I. Buszard |
| Abstract:
Eight cane management techniques were used to determine their effects on yield and winter hardiness. Treatments, including thinning canes to 5, 10 or 15 per metre, biennial cropping, alternate side of row cropping, chemical primocane suppression and a control, were applied to the raspberry (Rubus idaeus L.) cultivars, Festival, Latham and Newburg. Fruits were harvested every 2nd day. Yield and weight of 10 berries were recorded at each harvest. Floricanes were removed following the last harvest. After termination of primocane growth in the autumn, node number, primocane height, and stem diameter were recorded. The following spring, winter injury (dieback and bud death) was recorded and fruiting lateral development monitored. Control of primocanes increased yields and berry size in the first season. Reductions in intercane competition reduced primocane height but increased node number per cane and cane diameter. Results of treatments on winter survival and floral development in the second year are presented. | |
