                                                      OBJECT.

In a previous paper (" Silage Investigations at Bangalore ", Memoirs of the
Department of Agriculture in India, Chemical Series
, Volume X, No. 10) the results
of a study of the ensilage of Jowar (Sorghum vulgare) were reported. There, the
ensilage was done only under one set of conditions. In the present experiment
an attempt has been made to determine the effect of (a) rate of filling and ( b)
addition of water on the resulting silage, with the same material.

                                          METHOD OF EXPERIMENT.
The following scheme was adopted. Ensiling was done in pits of rectangular
shape, 12 feet long, 6 feet wide and 8 feet deep, the increased depth being employ-
ed to diminish the exposed surface, while ensuring a greater capacity. The Jowar
was harvested when in prime condition for ensilage, and was chaffed to bits of
about an inch in length. The chaffed material was employed for filling the pits.
Generally, the harvesting of the crop was done in the forenoons and the chaffing
and filling in the afternoons. Portions of the thoroughly mixed, chaffed Jowar,
being filled in the pits, were enclosed in loosely woven tared gunny bags, and the
weight of the green sample determined. The bags were buried in the pits at
suitable depths. During the filling of the bags, separate samples were taken for
immediate analysis.

Pits were filled according to the following scheme :—

Pit No. 1. Slow filling with watering.
Pit No. 2. Slow filling without watering.
Pit No. 3. Rapid filling with watering.
Pit No. 4. Rapid filling without watering.
