The present investigation entitled “Response of turmeric (Curcuma longa L.) cv. Salem planted by pro tray seedling method to spacing and nutrients” was carried out during the year 2020-2021 at AICRP on spices, Asond Block, Central Experiment Station, Wakavali.

At various periods of growth, the spacing (S₄) substantially recorded the maximum growth and developmental characteristics; nevertheless, the spacing (S₁) significantly recorded the highest plant height. The highest characteristics of mother rhizome, primary rhizome, secondary rhizome and highest yield per plant were observed in spacing (S₄). Although the spacing (S₁) recorded the best yield per plot and yield per hectare. In the case of different spacing quality character i.e. curcumin was non-significant. However, the characteristic of growth and developmental, mother rhizome, primary rhizome, secondary rhizome, yield per plant, yield per plot and yield per hector were recorded highest in F₂ fertilizer level and lowest in F₃ fertilizer level. Quality character i.e. curcumin was non-significant in the case of fertilizer levels.

During the course of an investigation, the interaction effect between spacings and fertilizer levels revealed that the treatment combination of S₄F₂ recorded significantly maximum growth and developmental characteristics which was superior over the rest of treatment combinations except for plant height which was maximum in S₁F₂ interaction. The characteristics of mother rhizome, primary finger, secondary finger and yield per plant were also recorded the maximum with the same treatment combination S₄F₂. However, significantly the highest yield per hector and yield per plot was recorded with a treatment combination of S₁F₂. Curcumin content was not significantly influenced by the interaction effect of spacings and fertilizer levels.

From the above investigation it is concluded that for securing higher yield per hectare under the Konkan region, it is advisable to grow the turmeric with S₁ spacing (30 × 15 cm) with F₂ (220:50:150 NPK kg/ha) fertilizer level.
