Variability study in sorghum (Bhal and Costal zone crop) field experiments and yardstick there of

Abstract

The data on C.V. % for sorghum crop yield along with other details of 87 field experiments conducted during 1989-90 to 2014-15 at Dhandhuka center (Bhal and Coastal zone crop), were collected and analyzed. The frequency distribution tables were prepared for various experimental factors. The upper fiducial limits (the yardstick) of C.V. % at 95% confidence based on non central 't' distribution were worked out for accepting the results of sorghum crop experiments which emerged as 17 %.
