Tipping off pruning and use of biofertilizer in the growth of pecan trees

Abstract

In Brazil, the cultivation of pecan trees has substantially increased in the last years, thus requiring the development of scientific research and technologies to improve it. Thus, the aim of this study was to evaluate the tipping off effect associated with the use of biofertilizer in the growth of newly implanted plants in their final site. The treatments consisted of : control; application of “supermagro” biofertilizer; tipping off of plants, and tipping off associated with the use of biofertilizer. The variables evaluated were: plant height; plant growth rate; stem thickness; number of leaves, and number of leaves/stem height ratio. In addition, leaf nutrient content analysis was performed. Tipping off and the use of biofertilizer provide greater growth of the plant height and cultivar scion diameter after sprouting. Thus, tipping off associated with biofertilizer can be used in the early phase of the pecan orchard implantation to provide the best plant development.
