Abstract:
The present studied was carried out as observational trial in different ongoing research programmes during kharif 2021 and 2022 at Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidhyalaya, Raipur, Chhattisgarh.

From all the three date of transplanting, mite infestation was relatively low in D1 transplanting (1st July) which were older than others.
