The role of a microbial consortium on gas exchange and water relations in Allium cepa L. under water and nutritional deficit conditions.

Synergistic studies of microorganisms in the last decade have been mostly directed towards their biofertilizing effects on growth and crop yield. Our research examines the role of a microbial consortium (MC) on physiological responses of Allium cepa hybrid F1 2000 under water and nutritional deficit in a semi-arid environment. An onion crop was established with normal irrigation (NIr) (100% ETc) and water deficit (WD) (67% ETc) and different fertilization treatments (MC with 0%, 50% and 100% NPK).

strain selection with plant growth-promoting mechanisms as potential elicitors of systemic resistance to gray mold in pepper plants.

Certain soil bacteria produce beneficial effects on the growth and health of plants; hence, their use is steadily increasing. Five strains of with plant growth-promoting potential were selected in this study, which produced indole-3-acetic acid levels below 50 µg.mL.
