Response of bluberry to soil (SL) or soil foliar integrated (SFI) multicompound fertilizers application

Abstract

An experiment was carried out in 2001and 2002 with blueberry (Vaccinium corymbosum L) cv. Bluecrop on commercial field. One year before the trial was started, plants have been already grown on sandy soil mixed with sawdsut compost in the rows. Three fertilizers treatment were applied, each in three replications. The size of mentioned single replication plot was 240 sq.m. As a source of nutrients the multicompound fertilizers NITROPHOSKA perfect 15-5-20+micro and BASFOLIAR 12-4-6 were used. During the vegetation period the soil along the plant rows was sampled simultaneously with the index plant parts. EC as well as pH were measured in the soil samples and macroelements concentration were determined in both i.e. soil and plant samples. The influence of applied fertilizers on the yield of berries was evaluated as well. The fertilizers used differenciated the plant available nutrients content in the upper soil layer and modified their concentration in an index plant leaves. Nitrogen phosphorus, potassium as applied on SFI way influenced the plants growth and their yielding.
