Efficacy of Methylobacterium oryzae Supplemented Sargassum wightii Seaweed Liquid Fertilizer on Chilly and Tomato Plant Growth

Abstract

Liquid seaweed fertilizer gaining interest due to their use in crop productivity. The present study was designed to evaluate the impact of Methylobacterium oryzae amended liquid seaweed fertilizer on domestic plants like chilly and tomato. The Sargassum wightii methanolic extract was maximum (137 mg/g) among other solvent tested. Extract showed 0.456mg/mL, 1.587 mg/mL, 0.78 mg/g, 5.27 mg/g, 0.63 mg/mL, 0.98 mg/mL, 0.285 g/mL and 0.546 g/mL of total phenolic, total flavonoids, total chlorophyll, total carotenoids, total protein, total carbohydrates, total lipids and total aminoacids respectively. The maximum survival of Methylobacterium oryzae was observed at 40 % of Sargassum wightii SLF extract with 3% Methylobacterium oryzae culture concentration and has viability of 750 x 106 CFU/l after 6 months. Impact of foliar sprayed liquid fertilizer on the chlorophyll, internode and shoot length had been promising over seed soaked.
