Effect of Variable Seeding Density and Cell Spacing on Dill (Anethum graveolens L.) Growth, Yield and Biochemical Parameters under Deep Water Culture (DWC)

Abstract

The present investigation entitled “Effect of variable seeding density and cell spacing on dill (Anethum graveolens L.) growth, yield and biochemical parametersunder DWC (Deep Water Culture)” was carried out at Landcraft Aquaponics Unit, Hatkanangale, Tal. Hatkanangale, Dist. Kolhapur, (MS) India during December, 2021 to February, 2022.An experiment was comprised of factors; cell spacing and seed density, laid into Factorial Completely Randomized Design (FCRD) with two replications. The factors acell spacing and seeding density had significant effects on growth, yield and yield contributing characters of dill under DWC. For yield and yield contributing characters, treatment S1D5 recorded significantly superior weight of leaves (51.95 g/cell), weight of stems (14.32 g/cell), weight of roots (10.99 g/cell), fresh yield of dill (65.99 g/cell) and yield of leaves (106.96 kg/100 sqm.). The treatments did not differ significantly for biochemical parameters (chlorophyll content, micronutrient content, ash and moisture percentage). There was no any significant difference reported among the treatments for sensory parameters (colour, texture and aroma). Hence, on the basis of growth, yield, biochemical and sensory parameters, it is concluded that the treatment S1D5 i.e. 18 cell-sheet (spacing- 14 cm x 14 cm) with seed density 20 seeds per cup was found the best treatment for higher yield in Dill cultivation under Deep Water Culture Technique of aquaponics.
