Project Description

This study will determine if the application of a biostimulant (OHD Liquid) provided by Green Power Energy as a foliar spray or soil drench, results in a yield benefit and a decrease in Blossom End Rot (BER) for processing tomatoes over two crop cycles.
The study will be undertaken in the field (northern Victoria) during the 2017/2018 season on two trial sites. At the commencement of the season, pre-trial soil sampling will be required to establish spatial variation of physicochemical properties within and between rows.
The treatments will be applied either as a foliar spray or as a soil drench, depending on consultation with APTRC and the grower as to which method is practical. The cultivar tested will be that as selected by the grower for the upcoming season. The frequency of application will be determined by results of the current glasshouse trial. During the growing period, the grower will manage the trial plots according to regular practice.
At harvest, the tomatoes will be hand harvested from a 2 m section within each plot and the reference fruit separated from unripe or blemished (BER) fruit. Fruit yield, Brix, pH and nutritional content will be assessed. The plant tissue will be analysed for biomass and nutrient content. Soil samples will be collected pre-trial, mid trial and during harvest and analysed for a suite of physicochemical properties. Soil from each plot will be assessed for the persistence of nitrogen-fixing bacteria by selective culturing.
