Effect of Fertigation on the Growth and Productivity of Strawberry

Abstract

The aim of this study was to determine the types and compare the highest productivity of fertigationrate. The objectives of fertigation Technique is to measure the growth, number of fruit, TSS and firmness of 4strawberry cultivars (B5, Toyonoka, and two hybrid line BQ and QN). Each cultivars was set into 3 parameters offertigation (14-7-32) rate of 0.05, 0.10 and 0.15 g/plant. This research was designed into 4 x 4 factorial in orderthe data to analysed by SAS program. The results found that the suitable levels for the maximum productivity is0.05 g/plant. The analysis of elements in leaves the Phosphorus and Potassium in leaf were dramatically decreasedafter 5 months of plantation the suitable fertigation program for strawberry plantation in Nahaew District, LoeiProvince should be as follows : apply 14-7-32 at 0.05 g/plant on December and January and 0:0:1 or 0:1:2 at 0.05g/plant increase on February and March.
