Abstract

It is known that the fertilising principles nitrogen and phosphoric acid,in the solube manures like ammonium sulphate and super-phospate are immediately fixed in the soil soon after the application of these other crops as the rice crop is mainly grown under pudded and swampy conditions.Usually in the carrying out of manurial experiments on rice ,elaborate precautions are usually taken against the leaching and washing out of manures by having separate bunds 1.5to broad and 1'high and channels 2'wide and irrigation is carefully controlled to manured plots after the application of the manures.A simple preliminary experiment conducted at the Agricultural Research Station.Maruteru(C.R.)Srinivasan(1929),indicated that there was no effect of ammonium sulphate beyond the area within which it was applied.Detailed experimental data were essential before any conclusions could be drawn and to arrive at a definite conclusion.un experiment was conducted at the Paddy Breeding Station.Coimbatore during the year 1933-34.
