Abstract: Sunflower has made significant contribution to increase edible oil production in the country as well as world. As this crop is day neutral and thermo insensitive can be grown throughout the year. Area under this crop is gradually decreasing due to inherent problems like improper seed filling, low seed yield per hectare and non-availability of quality seed for seed production. hybrid seed production in sunflower crop to confirm the usefulness of pre-flowering chemical sprays for yield maximization with better seed quality during different seasons and sowing dates as well as storability study by using the insecticides, botanicals and halogens, under the transitional agro-climatic conditions of Maharashtra. Under this back scenario, the present studies were conducted to know the effect of growing seasons, dates of planting in each season and chemical sprays (boron and TIBA) at ray floret initiation stage on crop growth, seed yield and seed quality of parental line of sunflower hybrid (Phule Raviraj) and the mid storage seed treatments with insecticides, botanicals, halogens and accelerated ageing on storability of the seeds harvested from three different seasons in hybrid sunflower. The two experiments were conducted during 2009-10 to 2010-11 years at the Post Graduate Institute Research Farm, Department of Agricultural Botany, Mahatma Phule Krishi Vidyapeeth, Rahuri (Maharashtra) with split plot design in three replications for field study. The significant increase the number of filled seeds per capitulum, seed weight and seed recovery percentage was also recorded due to the TIBA spray in all the seasons as compared to control. The significant increase the number of filled seeds per capitulum, seed weight and seed recovery percentage was also recorded due to the TIBA spray in all the seasons as compared to control.
