Randomized trial evaluates planting time and spacing effects on turmeric yield in West Bengal, indicating optimal conditions for farmers.

This research aims to determine how different planting times and spacing affect the yield and quality of turmeric in West Bengal.
Field study conducted in Terai region with split plot design and three replications.
Different planting times (first fortnight of April) and spacing combinations (30×30 cm, 50×30 cm) were evaluated.
Measurements included plant height, number of leaves, rhizome weight, and curcumin content.
Highest fresh rhizome yield of 24.3 t/ha was achieved with planting in the first fortnight of April at 30×30 cm spacing.
Curcumin content and morphological parameters were significantly influenced by planting time and spacing.
Increased spacing resulted in higher primary rhizome weight, particularly at 50×30 cm.

Mandi et al. (2025) studied this question.
