Abstract
During the past seven years attempts are being
made to fit in a short duration American cotton for the deltaic rice
lands of Tanjore, as a well irrigated crop in summer, and capable of
recording good yields of the order of 800 lbs. or more of kapas per
acre, with a quality of lint suitable for spinning 36 counts. For this
purpose, the imported variety P. 216F from punjab, with a duration
of five months, was found to be suitable. This cotton has now
spread over an area of about 6,000 acres in the districts of Tiruchira-
palli, Madurai, Tanjore, North Arcot, South Arcot and Chingleput.
Although the practice of growing cotton in the tankfed rice lands
after harvest of paddy is popular with the cultivators of the
Ramanathapuram, Tirunelveli and Madurai yet certain cultivators of
the deltaic areas of Tanjore and other centres feared that the
cultivation of cotton might depress the yield of paddy. Observations
were therefore made for a period of three years on the yield of paddy
in the rice fallows where cotton was grown during summer, at
Aduthurai, Palur and Coimbatare representing deltaic, coastal and
non-deltaic rice lands, with different durations of fallow periods.
The purpose of this note is to record the results of the observations.
