“…The genotypes that have higher number of leaves per plant and produced more tillers gave the best rhizome yields (Chukwudi et al, 2020) (Chukwudi et al, 2020;Lepcha et al, 2019). A high number of leaves/plant was recorded in the range of 166.56 to 245.16 (Babu et al, 2019) which may be due to relatively low temperatures combined with low light intensity that contributed to development of more chlorophyll in ginger plants grown in shade leading to higher number of leaves (Vastrad et al, 2006).The variation in number of leaves/hill among the genotypes may be due to differences in genetic constitution and genotypic potential of genotypes and interaction of genotypes with conducive environmental conditions. Bold Nadia exhibited highest significant number of tillers/plant (6.33) which has 5.56% increase over Local ginger followed by Bhaise (6.08).…”

A study was carried out for three years (2019, 2020 & 2021) in the experimental field at ICAR Research Complex for NEH Region, Mizoram Centre, Kolasib, Mizoram to check the performances of seven ginger genotypes viz., Gurubathani, Bold Nadia, Bhaise, John's ginger, PGS 121, PGS 95 and PGS 102 against Local ginger cv Thingria and their economic feasibility for commercialization in Mizoram, India. Out of seven genotypes when compared with Local ginger cv Thingria, five genotypes have out yielded Local cultivar in the range of 21.25 to 45.45% with Bhaise having 45.45% higher rhizome yield than Local ginger. On the other hand, Bold Nadia possesses a combination of good quality traits. The highest B:C ratio was obtained in Bhaise (2.08) followed by PGS 102 (1.99), Gorubathani (1.95) and Bold Nadia (1.87). The highest cost of cultivation was contributed by labour cost which was 53.40% of total cost of cultivation. The four genotypes viz., Bold Nadia, Bhaise, PGS 102 and Gorubathani can be selected as potential genotypes possessing optimum combination of all traits. Based on economic analysis, these genotypes can be considered for commercial purposes under Mizoram condition. Different production systems such as intercropping, pro-tray technology, and bulb extraction method may increase the overall income of farmers. Farmers need to venture the possibilities of value addition in ginger on commercial basis. Government intervention is required for creating marketing infrastructures, initiating youth-centered schemes, occasional skill training and developing farmer-friendly policies to protect them from market risks and exploitation. Ginger has been an important horticultural crop and widely marketed spice crop of Mizoram, a potential enterprise contributing to state economy

“…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]. For example, Ajithkumar et al [16] showed that the dry rhizome yield of ginger plants grown under 80% shade decreased by 51%, 151%, 113%, and 45% compared to those grown under full sun or 20%, 40%, or 60% shade, respectively.…”

Strategies to Reduce Radiation Stress in Open-Field Ginger and Turmeric Production

et al. 2022

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.
