Description In greenhouse experiments, the germination and emergence of
pearl millet, sorghum and groundnut in an Alfisol, was found to
decrease significantly with reduction in soil moisture content and
increase in bulk density. The effect of increasing bulk density
was considerable at low soil moisture contents. A bulk density of
1.45 g ~ m 'an~d moisture contents ranging from 8% to 11% were
observed to be favorable for germination and emergence of all the
three crops. A bulk density of 1.65 g cm-3 was critical for
emergence of pearl millet and sorghum. Excessive dryness and high
bulk density were detrimental to germination as well as seedling
emergence. Initiation of germination occurred when the gravimetric
moisture content ranged from 4% to 8% for the three crops. A
gravimetric moisture content greater than 192 significantly
decreased germination and emergence. Emergence was delayed by one
or two days when the soil was at higher bulk density in the low
moisture content ran es. Rate of emergence was faster at a bulk
density of 1.45 g cmS than at either 1.55 or 1.65 g om-$. In the
wet moisture range, the rate of emergence was faster at all the
three bulk densities than in the dry moisture ranges. Emergence
increased with increase in moisture content. Increase in bulk
density decreased the emergence for the three crops.
