Effect of Growing Condition and Spacing on Seed Quality Parameters in Hybrid Seed Production of Brinjal (Solanum melongena L.) under Shade House and Open Field Condition

Present investigation was undertaken in order to know the effect of growing condition and spacing on seed quality parameters in hybrid seed production of brinjal. A field experiment was carried out at the Hi-tech Horticulture Unit, Saidapur Farm, University of Agricultural Sciences, Dharwad during Kharif 2012-2013 and seed quality parameters were conducted in the Seed Quality and Research Laboratory, Seed Unit, University of Agricultural Sciences, Dharwad. There were two growing conditions viz., open field (G₁) and shade house (G₂) condition with four levels of spacing (S₁ = 60 × 45, S₂ = 60 × 60, S₃ = 60 × 75 and S₄ = 60 × 90 cm ) and it comprised of eight treatments with three replications in Randomized Block Design in factorial concept. Between two growing condition, shade house grown condition recorded significantly higher germination (82.8%) and vigour index (1426) as compared to open field condition. Among the spacings better seed quality traits were recorded with 60 × 75 cm spacing.
