Abstract

An experiment was laid out in a 4x2 factorial design, with 4 levels of γ-irradiation (0,5,10&15 Krad) and two dates of sowing (15th September and 15^th October) on papaya cv. Kesar King. The results indicated that germination percentage, survival percentage and plant growth increased with the increased in γ-irradiation upto 10 Krad. Early sowing of seed (15^th September) showed better germination (73%), survival (70%) and plant growth as compared to late sowing (15^th October). Interaction between γ-irradiation of 10 Krad and early sowing of seed (15^th September) was found superior to all the other treatment combinations to obtain optimum germination percentage, survival percentage and plant growth.
