Study on variability in field experiments on Sugarcane crop and yard stick there of 

Abstract

The data on C.V. % for sugarcane crop yield along with other details of 389 field experiments conducted during 1997-98 to 2014-2015 at Navsari center 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 sugarcane crop experiments which emerged as 11 %.
