Description Chickpea (Cicer arietinum L.) is a crop of economic
importance and also an important source of protein in the
diet of people in India as well as in other countries.
Total protein content in the diet of people in the developing
countries deserves special attention as large
segments of people in these areas are reported to suffer
from protein-calorie malnutrition. In the normal procedure
for estimating protein intake, nitrogen content is obtained
by the standard micro-Kjeldahl method and a factor is
used to convert the figure into protein percentage. In this
process, it is tactitly assumed that all the nitrogen is associated
with the protein. But, in fact, this is not true.
Therefore, any large variation in NPN content would affect
the estimated protein of the sample and would consequently affect the estimated protein intake'in the diet. However, some of the NPN probably consists of amino
acids and peptides which would be utilized. Attempts have
been made to determine NPN in various crops (Bell, 1963;
Boulter and Davis, 1968: Bhatty, 1972; Millerd, 1972). This study was conducted to determine the variation, if any, that might exist in chickpea samples and to identify the relationship between NPN and crude protein nitrogen in chickpea.
