دراسة بيئية لتحسين كفاءة الزراعة المائية باستخدام الأكتينوبكتيريا التي تعيش داخل جذور النباتات في الإمارات

الملخص EN

Hydroponics is one of the most important methods of modern agriculture in order to reduce the problem of water scarcity.

The United Arab Emirates has established many hydroponic farms due to their importance in agriculture and self- sufficiency of food.

The purpose of this study was to find a new environmentally friendly method in order to improve the efficacy of hydroponics by using a mixture of actinobacteria that produce more than one type of plant growth regulators (PGR).

Two different groups of actinobacteria producing PGR were isolated.

The first group lives in the rhizosphere outside the roots, and the second group lives inside the plant roots.

Both groups were tested for their ability to produce PGR.

The study proved the ability of the actinobacteria that live inside and outside the roots to increase the production of green pepper and lettuce and give more statistically significant results than the treatment that did not include actinobacteria.

The new finding in the current study was that the best treatment was that which involved the actinobacteria that live inside the roots rather than those that live outside the roots.

This study demonstrated a significant increase in the internal content of PGR in pepper and lettuce in the treatment that included actinobacteria that live inside the roots compared to the rest of the treatments, and this explains the increase in the yield.

This study is the first to use an environmentally friendly method to increase the efficiency of hydroponics using actinobacteria that live inside the roots.
