Effect of effective microorganisms on wheat growth under salt stress condition

ABSTRACT Effective microorganisms (EM) are important beneficial fungi and bacteria mixed culture that is used as an inoculant to improve soil quality and health, enhance plant growth, yield, and quality. This study was conducted to evaluate the effect of inoculating various concentration of EM (50,...

This study was conducted to evaluate the effect of inoculating various concentration of EM (50, 100 and 200 mL L-1) on growth of wheat (Triticum aestivum L.) seedlings, grown under NaCl regime (6 dS m-1), including fresh and dry weight, chlorophyll content, maximum fluorescence yield (Fm), variable fluorescence yield (Fv), optimum photosystem II (PSII) quantum yield (QY) and ratio of fluorescence decline in steady state (RFD).
