It appeared almost impractical to employ dye—binding techniques such as Udy procedures for measurements of protein in Agricultural commodities having a narrow range of Protein contents.In this study instead of using a number of separate cultivars,a mixture sample of 10 cultivars of white bean and also 10 cultivars of lentil was taken for the developement of standard curves and correlation coefficient.
Samples weighing 50 to 400 mg,were analyzed by a Udy protein analyzer.The observations (logs of %T)were highly correlated with the amounts of Protein measured by Kjeldahl method.The relationships between Protein in mg and the corresponding logs of percent transmission were presented graphically and as regression equations.The differences between protein contents of 20 cultivars of the two pulses by Kjeldahl and Udy using the above relationships were not statistically significant
