ABSTRACT

Field experiments were conducted during Kharif 2002 to 2003 to examine the impact of B,
Zn and IAA singly and in different treatments combinations at flowering and pod initiation stages
of pigeon pea variety Asha and ICPL81-119. The objectives was study the pattern of growth, dry
matter distribution, leaf and pod abscission as well as the assimilate partitioning for sink
enhancement. IAA irrespective of concentrations in combination with boron and zinc at flowering
and podding stages was found most effective in prevention of flower and premature abscission
and acceleration of assimilate translocation as well, while foliar application of the same at flowering
or pod initiation, individually, seems to alter the growth parameters or yield contributing traits
partially.
