 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.
