The Effect of Biofertilization and the Addition of Canola Seed Residues on the Growth of Pomegranate Transplants

Abstract

The investigation was carried out in pots at the greenhouse of the Horticulture Department at the Desert Research Center (DRC) on Wonderful pomegranate (Punica granatum L.) transplants during 2019 and 2020 seasons. This study contained three doses of canola seeds residues (CSR) 5, 10 and 15g/ transplants) each with or without one of two kind of bacteria Pseudomonas aerogenosa (B1) and
Pseudomonas genoculate (B2) beside control treatment in twelve treatments. Data were recorded on seedling growth parameter, leaf mineral content, organic carbon (OC) and organic matter (OM). Also targeted was to measure nitrogenase activity, CO2 evolution, and indole acetic acid (IAA) production in rhizosphere under pomegranate transplants. Also anticipated was to assess the content of N, P, and K in the shoots and roots of those Seedlings. The current study revealed that the greater the applied amount of canola seed residues caused, the higher the soil N, P, K, OC and OM, and in addition, the higher the shoot and root contents of N, P, and K. This is attributed to higher nitrogenase activity, CO2 evolution, and IAA production in rhizosphere below the pomegranate seedlings.
