Background & Objective:
With the increase in the world's population and demand for agricultural products, there is a need for sustainable and environmentally friendly methods to increase crop production. Therefore, this research investigated the effect of plant growth-promoting bacteria (PGPR) on lentil in rainfed condition.
Methods & Materials:
According to results, ten strains of PGPR were chosen from the Western collection in Iran. Out of those ten, the top six strains (Bacillus megaterium, Pseudomonas putida, Bacillus cereus, Bacillus sp., Bacillus licheniformis, Achromobacter sp.) were tested in a preliminary greenhouse experiment. Their impact on the yield quality and quantity, as well as the growth characteristics of three lentil cultivars (Local kordish, Bileh-Sawar, and Kimia), was then investigated in a rainfed environment in Kermanshah using a factorial experiment based on RCBD.
Results:
The results showed that the Kimia and Local kordish cultivars had the highest and lowest seed yield, with 1750 and 1290 kg ha-1, respectively. The Kurdish local variety's grain protein percentage (19.60%) was significantly higher than the breaded cultivars of Kimia and Bileh-Sawar. PGPRs caused a significant increase in grain and biomass yield and seed protein percentage. The highest grain and biomass yield were obtained in the treatment with Bacillus licheniformis and Pseudomonas putida strains with 1640 and 4600 kg ha-1, respectively.
Conclusion:
Based on the results, it appears that treating lentil crops with PGPRs could be an effective and eco-friendly solution to enhance both the quantity and quality of grain yield in rainfed cultivation within arid and semi-arid regions.
