“…Although high light and heat stress are known to negatively affect growth and yield of ginger and turmeric plants, our results for Experiment 1 show that using shade did not provide advantages compared to production under full sun (Table 3). Considering that some level of shade is typically recommended for these crops [11,13,[32][33][34], our findings suggest that the 60% shade level used in this study was excessive to increase rhizome yield. Accordingly, studies with ginger have reported higher rhizome yields under low (20% to 40%) compared to high (>60%) shade levels [13,16,35].…”

“…Similarly, studies with turmeric have shown that while shade levels from 30% to 50% increase vegetative growth and rhizome yield, shade >70% reduces yield [17,18]. Ferreira et al [34] reported no differences in rhizome yield in turmeric plants grown under 70% shade or full sun, and Sharangi et al [14] suggested that 50% shade is an optimum level to maximize photosynthesis and biomass production in turmeric. However, others have shown that shade levels ≥50% are adequate to increase rhizome yield.…”

Excess solar radiation can negatively affect growth and rhizome yield of ginger (Zingiber officinale) and turmeric (Curcuma longa) plants. Thus, the objective of this study was to evaluate the effect of 60% shade nets (Experiment 1) as well as white and red kaolin sprays during two production stages (early establishment vs. entire cycle) (Experiment 2) on field-grown ginger and turmeric plants. In Experiment 1, plants were propagated from seed rhizomes (R) or second-generation rhizomes from tissue-cultured plants (2GR), while only R were used in Experiment 2. There were no differences in rhizome yield in response to shade in Experiment 1, with mean values of 644 and 692 g in ginger and turmeric, respectively. Overall, 2GR ginger plants produced a higher rhizome yield (880 g) than R plants (425 g), but no yield differences were measured in turmeric. In Experiment 2, for both species and regardless of kaolin color, sprays applied during the entire cycle increased photosynthesis and stomatal conductance and reduced leaf temperature and transpiration compared to control. Rhizome yield was also up to 87% higher in ginger and 47% higher in turmeric plants sprayed with kaolin. Spraying plants with white kaolin during the early season establishment of these crops can be an effective strategy to reduce radiation stress for open-field production.

Curcuma xanthorrhiza RoxB. is a medicinal plant found in Indonesia and is often cultivated for therapeutic purposes. Curcuma xanthorrhiza typically thrives in shaded, low-light environments. In this study, plant growth, photosynthetic rate, and chlorophyll content of C. xanthorrhiza in the same growing environment with different shade treatments were evaluated. The level of shade was adjusted using paranet at 0%, 25%, 50%, and 75%. Growth observations of C. xanthorrhiza were carried out from 1 to 6 months after planting (MAP). Chlorophyll content was measured using a UV-Vis spectrophotometer at 649 and 665 nm. The photosynthetic rate was measured using Li-Cor 6400 at 5 MAP. The results revealed that 50% shade gave the best response for plant height at 2 MAP. However, the highest number of leaves was found at 25% shade at 4 and 5 MAP. The shade level of 25% produced a significant response for C. xanthorrhiza rhizome biomass. The highest photosynthetic rate was found at 0% shade (26.69 µmol CO2 m-2s-1) and the lowest at 75% shade (15.12 µmol CO2 m-2s-1). Meanwhile, the chlorophyll content and number of tillers of C. xanthorrhiza leaves were unaffected by shade treatment. This study shows that shade treatments at 25%-50% levels gave the best growth responses in the C. xanthorrhiza plants.
