Abstract A study was conducted to examine the association between Rhizobium and VAM fungi on kudzu plant growth response drought stress in coastal dry land. The research carried out three phases: (1) germination of seeds; (2) multiplication Rhizobia inoculums; (3) inoculation and/or bacteria plants grown at various soil moisture content. At phase, pot experiment for 8 weeks with a arranged based 4 x treatment factorial Completely Randomized Design replications test source inoculum content (25%, 50%, 75%, 100%). Observations were made on: Rhizobial infection activity nodulation; activity; growth, 4) population dynamics rhizobacteria. results showed that rhizobia alone not able increase bacterial root nodulation, fungal infection, growth. Inoculation stimulate nodule-forming activity, combination rhizobial roots shoots, but always nodulation. rates even up level 75%. This means resistance maintain high levels stress.

Arbuscular mycorrhizal fungi (AMF) play a crucial role in plant health due to their ability improve tolerance biotic and abiotic stresses. Our aim was evaluate the effectiveness of pool native AMF from harsh environment on performance changes soil attributes under different levels drought. An experiment using maize established, varying water content simulate severe drought (30% water-holding capacity [WHC]), moderate (50% WHC) no (80% WHC, control treatment). Soil were measured (enzyme activity, microbial biomass, root colonisation biomass nutrient uptake). There two-fold increase when compared treatment, but there difference uptake. Under drought, highest enzyme activities related phosphorus (P) cycling P indicating higher immobilization. The observed plants findings demonstrated that better use inoculum varied according levels, with biomass.

Utilizing water resources rationally has become critical due to the expected increase in scarcity. Cacti are capable of surviving with minimal requirements and poor soils. Despite being highly drought-resistant, cacti still faces limitations realizing its full potential under drought-stress conditions. To this end, we investigated interactive effect humic substances (Hs) arbuscular mycorrhizal fungi (AMF) on cactus plants drought stress. In study, a pot experiment had three irrigation levels (W1: no irrigation, W2: 15% field capacity, W3: 30% capacity) two biostimulants (Hs soil amendment AMF inoculation), applied alone or combined. The findings show that W1 W2 regimes affected performance. However, Hs and/or significantly improved growth. Our results revealed increased generation reactive oxygen species. application nutrient uptake anthocyanin content free amino acids. Furthermore, soil's organic matter, phosphorus, nitrogen, potassium contents were by these biostimulants. Altogether, using combination can be an effective sustainable approach enhance tolerance conditions, while also improving quality.
