Abstract
An experiment was carried out in the Department of Horticulture, Janta College, Bakewar, Etawah (UP) during two crop seasons in split plot design, using the commercial cultivars of W. somnifera viz., cv. Poshita and cv. JA - 20 as main plot. Two planting distance 30 x 30 cm2 and 30 x 20 cm2 were used as sub plot. The plants were raised in nursery bed and transplanted after 30 days of sowing. After 30, 60 and 90 days of transplanting the plants were sprayed with IAA 100 ppm, IAA 200 ppm, GA 50 ppm, GA 100 ppm, CCC 2000 ppm and CCC 3000 ppm solutions, whereas in control they were sprayed with distilled water (sub sub-plot). Results abstracted that cv Poshita produced higher root – shoot ratio as compare to cv JA – Planting distance 20. 30 x 20 cm2 gave maximum root yield per hectare however stand geometry had not any significant effect on root yield per plant. Both the concentration of CCC (2000 and 3000 ppm) provided maximum root – shoot ratio with highest root yield per plant and per hectare.
