This review highlights the study made for identification of the soil characteristics influencing on the blast
disease in the rice fields of Bundi district, Rajasthan (India). Physiochemical analysis like pH, EC,
Carbon, nitrogen, phosphorous and potassium contents were tested. The pH of soil ranges from 7.14 to
8.28. EC ranges between 220
s to 430
s. O C ranges from 0.37 to 0.85%. Nitrogen content varied from
.035% to .087%. Phosphorus ranges from .28kg/ha to .65kg/ha. Potassium ranges between 350kg/ha to
396kg/ha.
Alkaline pH, high concentration of salt, organic carbon, nitrogen and low concentration of potassium and
phosphorous, infects the plant health leads to the blast disease in bundi district, mainly observed in
keshavrai patan.
