Description In order to study the effect of interspecies competition and test the plant type concept, two experiments were conducted over two years during Kharif 1983 and 1984
under auspices of the All India Co-ordinated Sorghum
Improvement Project. In experiment I, twenty genotypes of
sorghum differing in canopy structure and genetic background
including released and prerelease varieties, hybrids and
some of the parental lines were grown in intercropping with
a pigeonpea variety, HY 8 as well as solecropping. The
intercropping represents inter-species competition while
sole cropping represents intra-species competition. The
competition effects due to sorghum, due to pigeonpea and due
to sorghum x pigeonpea interaction were studied in second
experiment by growing four sorghum hybrids and four different pigeonpea varieties in all possible combinations.
Experiments were laid out in RBD with three replications.
Developmental characters were recorded at three stages of
growth and yield characters at maturity
