Abstract

Garden pea (P. sativum sp. hortense) is a crucial vegetable crop cultivated globally in cooler regions, serving both as a fresh vegetable (green pea) and a dried pulse. Despite its extensive production, pea yields are often hindered by various biotic (diseases) and abiotic (environmental) factors. Among the biotic constraints root rot disease caused by Rhizoctonia solani is the major limiting factor in pea production. To know the status of root rot disease, survey was conducted in the major pea-growing regions of Rajasthan during the Rabi season of 2022-23 which revealed significant prevalence and economic concern. The study focused in Zone-III A of Rajasthan viz., which includes districts like Ajmer, Jaipur, Tonk and Dausa. The findings showed an average disease incidence of 23.12% across the surveyed districts of Rajasthan. Jaipur had the highest incidence(29.01%) while Dausa recorded the lowest (18.13%).This survey provides crucial data on the spread of root rot in continuously pea growing districts of Rajasthan, which need effective disease management strategies

Conclusion

The survey of four districts (Zone-III A of Rajasthan) revealed that no location was free from the disease. Among all surveyed districts, disease incidence ranged from 6.89% to 38.14%, with an overall mean of 23.12%. The highest mean disease incidence was observed in Jaipur district, while the lowest was in Dausa district (18.13%).
