Abstract:
The present study entitled “Influence of plant spacing and nitrogen doses on yield and growth of turmeric” was undertaken at College of Horticulture, DBSKKV, Dapoli during the year 2021 to 2022 by considering the importance of turmeric under agro climatic condition of Konkan. In the interaction effect of treatment combination S₁N₁ (45 cm × 45 cm; 300 kgha^-1 N) recorded the highest number of leaves (14.98) and tillers per plant (3.91) whereas the interaction effect of treatment combination S₃N₁ (45 cm × 15 cm; 300 kg ha^-1 N) found the maximum plant height (110.19 cm). In post harvest parameters, treatment S₁N₁ (45 cm × 45 cm; 300 kg ha^-1 N) observed the maximum number of primary fingers (15.51), the highest number of secondary fingers (19.42). The highest yield per hectare in tones (58.48 t) was recorded in treatment combination S₃N₁ (45 cm × 15 cm; 300 kg ha^-1 N). The economic analysis of the yield data revealed that S₃N₁ i.e., 45 cm × 15 cm and 300 kg ha^-1 N recorded the more gross return (Rs. 1321800) and B:C ratio (1.91).
