Conjoint Application of INM Modules on Vegetative, Flowering, and Seed Yield in French marigold

Abstract

The present investigation was carried out at Sher-e-Kashmir University of Agricultural Sciences and Technology, Chatha, Jammu during 2018-19. The experiment was laid out in Randomized Block Design and comprised of twenty-three treatments replicated thrice. Among the various treatments, maximum plant height (90.10 cm) and highest number of laterals (21.89) were recorded with treatment T7 comprising of 75 % RDF + Spent mushroom compost (1 kg/m2) + 1% foliar spray of MKP (00:52:34). Lesser number of days taken to 50% flowering (70.22 days), number of flowers/plant (86.78), maximum flower diameter (6.20g), weight of flower (5.78 g), flower yield per plant (500 g), seed yield/plant (105.91 g), 1000 seed weight (11.67g) was recorded with the treatment of 75 % RDF + Spent mushroom compost (1 kg/m2) + 1% foliar spray of MKP (T9). Maximum plant spread (68.44 cm) was recorded with treatment comprising of 75 % RDF + Spent mushroom compost (1 kg/m2) + Biofertilizers (T6). However, minimum electrical conductivity of seed leachate (0.688 µmhos/cm/g) was recorded with 25 % RDF + Spent mushroom compost (1 kg/m2) + Biofertilizers (T20). The effects of treatments on flowering duration (days) and shoot: root ratio was found to be non-significant.
