A field experiment was conducted at Punjab Agricultural University, Ludhiana during kharif 2016 to study the effect of eight growth retardant treatments viz., control, water spray, MH @ 200, 250 and 300 ppm and TIBA @ 25, 50 and 75 ppm and two sowing dates (May 15 and May 30) on yield attributes and yield of pigeonpea. May 15 sown crop produced significantly higher number of branches, pods plant-1 and grain yield than May 30 sown crop. Crop sown on May 15 recorded the highest seeds pod-1 and 100-seed weight. Various yield attributes viz., secondary branches plant-1 and pods plant-1 were statistically higher with application of TIBA @ 75 ppm than all other growth retardant treatments and control but was statistically at par with TIBA applied @ 50 ppm. As a result, highest seed yield of pigeonpea (14.4 q ha-1) was recorded with application of TIBA @ 75 ppm although at par with foliar application of TIBA @ 50 ppm but was 22.9 per cent higher than control. Among the growth retardants, TIBA @ 75 ppm produced highest number of seeds pod-1 and 100-seed weight.
