Abstract
This study aimed to evaluate the growth of plants and the precocity of strawberry production under different root pruning intensities at planting time. Bare roots plants with 12 millimeters crown diameter produced in nurseries from the Patagonia region, Argentina were used. The planting was carried out on May 12th 2010 into experimental plots with non-fumigated soil. The treatments consisted of three cultivars (Camarosa, Florida Festival and Camino Real) and three pruning intensities (1/3, 2/3 and no pruning) on the total root length of the plants. The experimental design used was a randomized block design in a 3x3 factorial arrangement with three replications and 12 plants per plot and density of 11.1 plants m-2. Mature fruits were harvested from July 15th to December 14th 2010 and the production of fresh fruit was determined. There was no significative interaction between cultivars and pruning intensity. 'Camarosa' and 'Florida Festival' plants showed precocity and had the most abundant and heavier fruits during the precocity period. The different root pruning intensities did not affect the assessed variables. It was concluded that, in order to facilitate strawberry planting of the cultivars Camarosa, Florida Festival and Camino Real root pruning is possible, with no damages on plant growth and development, precocity and early fruit production.
Highlights
This study aimed to evaluate the growth of plants and the precocity of strawberry production under different root pruning intensities at planting time
Bare root plants are used in the establishment of cultivated fields in the annual strawberry production system in Rio Grande do Sul, Brazil
The success of the bare roots plants establishment requires an adequate depth planting. This precaution is very important since it is necessary to assure that root system is completely covered and crown base is on contact with soil (ANTUNES; DUARTE FILHO, 2005)
Summary
This study aimed to evaluate the growth of plants and the precocity of strawberry production under different root pruning intensities at planting time. The study aimed to evaluate the growth, precocity and production of three strawberry cultivars submitted to different root pruning intensities. Earlier fruit harvest was recorded for plants from ‘Camarosa’, with beginning of production in 89 days after planting (Table 1); similar to what was STRAWBERRY YIELD SUBMITTED TO DIFFERENT ROOT...
