Effectiveness of Single and Multiple Microbial Inoculation on Growth and Nutrients Uptake of Chinese Kale Seedling

Abstract

The study was performed to evaluate the effectiveness of single and multiple inoculation of beneficial microorganisms on growth and nutrients uptake of Chinese Kale (Brassica oleracea var. alboglabra). The experiment was performed in plug tray containing coconut husk compost as seedling media. The media was inoculated with single or multiple isolates of Azospirillum sp. (VAs 2), Beijerinckia sp. (VBe 75) and Actinomycetes (VAc 077). Randomized Complete Block Design was applied and each treatment was repeated three times. The results demonstrated that triple inoculation with VAs 2, VBe 75, and VAc 077 gave the highest shoot dry weight (2.927 g/plant) with the value of 20% higher than that of the control. Single inoculation with VAc 077 gave the highest root dry weight (0.360 g/plant) with the value of 32% higher than that of the control. The use of single and multiple isolates increased all
nutrient elements uptake (N, P, K, Ca and Mg) especially for N uptake which was 61% higher than the control.
