An experiment was conducted to investigate the mitigation of drought stress by foliar application of salicylic acid and potassium in mung bean. Treatments comprised of three drought stress (control, drought stress at flowering stage and drought stress at flowering and pod formation stages) and foliar application salicylic acid (100 ppm) alone and in combination with potassium (1%). Irrigation missing at flowering stage, affected less the growth and yield as compared with irrigation missing at both flowering and pod formation stage. Exogenous application of salicylic acid and potassium could mitigate the adverse effects of drought stress significantly.

Effects Of Drought

Abiotic stresses arising from climate change negates crop growth and yield, leading to food insecurity. Drought causes oxidative stress on plants, arising from excessive production of reactive oxygen species (ROS) due to inadequate CO2, which disrupts the photosynthetic machinery of plants. The use of conventional methods for the development of drought-tolerant crops is time-consuming, and the full adoption of modern biotechnology for crop enhancement is still regarded with prudence. Plant growth-promoting rhizobacteria (PGPR) could be used as an inexpensive and environmentally friendly approach for enhancing crop growth under environmental stress. The various direct and indirect mechanisms used for plant growth enhancement by PGPR were discussed. Synthesis of 1-aminocyclopropane−1-carboxylate (ACC) deaminase enhances plant nutrient uptake by breaking down plant ACC, thereby preventing ethylene accumulation, and enable plants to tolerate water stress. The exopolysaccharides produced also improves the ability of the soil to withhold water. PGPR enhances osmolyte production, which is effective in reducing the detrimental effects of ROS. Multifaceted PGPRs are potential candidates for biofertilizer production to lessen the detrimental effects of drought stress on crops cultivated in arid regions. This review proffered ways of augmenting their efficacy as bio-inoculants under field conditions and highlighted future prospects for sustainable agricultural productivity.

Effects Of Drought

Drought stress is one of abiotic stresses and has caused a significant deterioration in growth and yield of patchouli. This research was conducted in Reuleut Timu Village, Muara Batu District, Aceh Utara Regency, from July to December 2016, using split plot design in a Randomized Block Design with three replications. The main plot was mulch treatments (without mulch, rice straw mulch and black silver plastic mulch). The subplots were treated with different frequency of fertilizer application (once, twice and three times). The results revealed that the application of rice straw mulch has reduced the effects of drought stress, suppressed the soil temperature fluctuations, maintained soil moisture, which resulted in an increase of patchouli growth. Different frequency of fertilizer application did improve the oil yield, proline accumulation and drought resistance.

Analysis System

Three species of herbaceous perennials were tested on their ability to withstand and recover from drought stress periods of 2, 4, and 6 days. Eupatorium rugosum and Boltonia asteroides `Snowbank' were chosen because of their reported drought intolerance, while Rudbeckia triloba was chosen based on its reported drought tolerance. Drought stress began on 19 Sept. 1997. Plants were transplanted into the field the day following the end of each stress period. The effects of drought on transpiration rate, stomatal conductance, and net photosynthetic rate were measured during the stress and throughout recovery using an infrared gas analysis system. Leaf gas exchange measurements were taken through recovery until there were no differences between the stressed plants and the control plants. Transpiration, stomatal conductance, and photosynthesis of Rudbeckia and Boltonia were not affected until 4 days after the start of stress. Transpiration of Eupatorium decreased after 3 days of stress. After rewatering, leaf gas exchange of Boltonia and Rudbeckia returned to non-stressed levels quicker than Eupatorium. Growth measurements were taken every other day during stress, and then weekly following transplanting. Measurements were taken until a killing frost that occurred on 3 Nov. There were no differences in the growth between the stressed and non-stressed plants in any of the species. Plants will be monitored throughout the winter, spring, and summer to determine the effects of drought on overwintering capability and regrowth.
