Summary
Abstract: This long term experiment began in 1972. The experimental site is a
tropical area, with a minimum annual temperature of 14 deg C, maximum
annual temperature of 37.5 deg C, and mean annual rainfall of 1449
mm. The soil is characterized as Aeric Haplaquepts. The soil
properties are as follows:

Layer 1 0-22cm - 10 YR 8/4 very pale brown, sandy. Layer 2 22-52cm -
2.5 Y 8/4 pale brown, clay loam. ... View entire text

Quality Width of smallest plot is 10 m, Length of smallest plot is 20 m.
There are at least 3 replicates in the experiment. The experiment has
a randomized plot design. Bulk crop of rice was grown in 2-3 seasons
before laying out of the experiment after selection of the site. Based
on the fertility gradient (as far as possible) replicates were
assigned in such a way that all treatments in one replication had more
or less uniform fertility status. The treatments in each replication
were allotted as per random numbers chosen from standard statistics
text book. Absolute control (nil inputs). Other treatments serve as controls
for others. See references (in reference list) for full details.
