Using the acreage and yield estimates collected by the colonial
revenue administration,
Blyn
argued
that
there
was a small expansion
in per capita agricultural
output
during the 1890s (a decade of minimal
population growth), but a clear decline thereafter, so
that
although
overall
yields per acre rose very slightly over the first half of the
twentieth century, foodgrain availability
fell
by about 1 per cent per
year
between 1911 and 1947. Static overall yield figures do not mean
that
output
everywhere was stagnant, but
rather
that
progressive forces
were always cancelled out by regressive ones, and
that
periods of
dynamism were interspersed with periods of enervation. Market
demand did stimulate significant increases in crop production and
productivity, so
that
commercial crops with favourable market oppor-
tunities, such as cotton and sugar, achieved considerable yield
increases, and had consistently higher average productivity per acre
than
did foodgrains. However, even export crops with favourable
overseas demand performed less
well
in the difficult international
trading conditions of 1926-41
that
they had before 1914.
Blyn's
account of Indian agriculture is pessimistic, showing
that
foodgrain availability held up only at times of minimal population
growth, and
that
cash-crop
output
was dependent on the unstable
stimulus of international demand. His estimates have been subjected to
minute scrutiny, and the fragility of their empirical base expounded at
length. Estimates of agricultural
output
based on direct measurements
derived from rigorous and wide-ranging crop-cutting experiments
were not widely available until the 1940s. It is undeniable
that
much of
the raw
data
for crop
output
and yields before
that
was gathered very
casually
as
part
of the fiscal system, and the linkage between land tax
and
output
estimates may have encouraged under-reporting, especially
as the British bureaucracy progressively gave up day-to-day super-
vision
of
rural
administration after the political reforms of 1919.

George
Blyn,
Agricultural Trends in India, 1891-194/: Output, Availability and
Productivity, Philadelphia, 1966. It should be noted
that
this work substantially revised an
earlier set of estimates by the same author (The Agricultural Crops of India,
1893-1946:
A
Statistical
Study
of Output and Trends, Philadelphia, 1951) which
gave
a significantly lower
estimate for total
yield
increases. S. Sivasubramonian, in his 'National Income of India
1900-01 to
1946-7',
Ph.D. dissertation, Delhi
School
of Economics, 1965, shows an
11.1
per
cent
fall
in crop yields in the period 1900-46 based on
Blyn's
1951 estimates, as does the same
author's essay 'Estimates of gross value of output of agriculture', in V. K. R. V. Rao et al.
(eds.),
Papers on National Income and
Allied
Topics, Volume 1, London, i960, while
Blyn's
later work suggest an overall increase in yields of 9 per cent in the same period.
