Sturdiness Quotient (SQ), Khejri seedlings

Abstract

Sturdiness Quotient (SQ) is the growth standard to determine the good quality of seedlings at nursery conditions. The SQ of Khejri seedlings was studied at nursery conditions, but the SQ value was found to be contradictory with normal which is always less than six. In this experiment in two different years, the SQ value was more than six for the Khejri tree and it was not always less than six which is universal. Based on experimentation data the authors conclude that the SQ value of the khejri tree lies between 13 ± 7.
