complex organic macromolecules that contain carbon,
hydrogen, oxygen, nitrogen, and usually sulphur and
are composed of one or more chains of amino acids.
They are fundamental components of all living cells
and include many substances, such as hormones and
antibodies, that are necessary for the proper func-
tioning of an organism. It is evident from the data that
crude protein contents of berseem increased with an
increase in solution P levels up to a certain extent: i.e. a
maximum crude protein (20.61%) was obtained at a
soil solution P level of 0.30 mg/L, which was developed
by adding 92 kg P/ha in the case of sandy clay loam soil
(Table 17.10). On clay loam soil the highest crude pro-
tein content of 19.42% was obtained at a soil solution P
level of 0.35 mg/L, which was developed with the
application of 133 kg P/ha. In the case of sandy loam
soil, the maximum crude protein of 16.49% was also
obtained at the same soil solution P level of 0.35 mg/L,
which was developed with the application of 94 kg P/ha.
Chaudhary and Karwasra (1984) reported that crude
protein contents were increased with the application of
P fertilizer.
