Abstract:
The present field experiment was conducted at investigation carried out during Kharif + Rabi season of 2019-20 at the Herbal Garden, College of Horticulture, Mandsaur (M.P.). The experimental material comprised of nine treatment combinations of three plant spacing and three cultivars of turmeric. These treatments were sown in Factorial Randomized Block Design with four replications. The individual effect of planting geometry 45 × 30 cm (S₃) was recorded the maximum plant height, number of leaves, leaf area, dry weight of plant at harvest and number of tillers at 90 DAP. Similarly the physiological characteristic viz. LAI (1.086), CGR (1.043), RGR (0.348), LAD (36657.47) at 90-120 of growth stage and chlorophyll content (28.46 SPAD) at 90 DAP as compared to other plant spacing 45×25 cm (S₂) and 45×20 cm (S₁) respectively. The maximum yield viz. fresh rhizomes yield plant^-1 were observed maximum in 45 × 30 cm (S₃) and fresh rhizomes yield ha^-1 ((239.86)) were found maximum in S₁ (45 × 20 cm)) with quality parameter viz., oil content (4.13%) and curcumin content (5.49%) were observed maximum in S₃ (45 × 30 cm)). In case of cultivars, the Sonali (V₂) was significantly superior and was recorded maximum plant height, number of leaves, leaf area, dry weight of plant at harvest and number of tillers at 90 DAP. The physiological characteristics viz LAD (1.047), CGR (0.848), RGR (0.341), LAD (35348.78) at 90-120 growth stages and chlorophyll content (28.00 SPAD) as compared to other cultivars Suroma (V₁) and Ranga-3 (V₃). The yield characteristic viz. fresh rhizomes yield (300.86g) plant^-1 and fresh rhizomes yield (242.94 q ha^-1) was observed with cultivar Sonali (V₂) as compare to cultivars Suroma (V₁) and Ranga-3 (V₃) and quality characteristics viz. was exhibited oil content (4.18%) and curcumin content (5.47%) of rhizomes was significantly higher with cultivars Sonali (V₂) in comparison to other cultivars.
