A total of thirty isolates of A. alternata were collected from eastern Uttar Pradesh and parts of Bihar, India. All thirty isolates were evaluated for their growth and rate of growth at three different H+ ion concentrations (pH) viz. four, six and eight in PDA medium. Radial growth for all of the isolates of A. alternata was also found significantly maximum at pH 6 followed by pH 8 and pH 4. Also, it was noted that none of the isolate had statistically similar growth in different pH range. At pH 4, range of radial growth for thirty isolates ranged between 28.50 to 38.00mm, at pH 6, 90.00mm to 66.00mm whereas for pH 8 growth of A. alternata isolates ranged between 49.50 and 58.00mm. Likewise, rate of growth for all of the isolates of A. alternata was also found significantly maximum at pH 6 followed by pH 8 and pH 4. None but one of the isolate had statistically similar rate of growth in different pH range i.e. Mohobbatpur had 4.67mm and 4.58mm rate of growth at pH 8 and 4 respectively which were found statistically at par each other.
