Background. Taro (Colocasia esculenta) is one of the underutilized crops in Kenya, grown under a wide range of environmental and edaphic conditions. This crop has exceptional dietary value and numerous culinary applications due to its edible leaves and corms. However, the mineral nutrient composition of taro in Kenya is still not well known due to a lack of scientific information concerning production. Objective. To determine the proximate composition and mineral profile of taro under different watering regimes and planting densities in Embu, Kenya. Methodology. A study was conducted at the Kenya Agricultural and Livestock Research Organization (KALRO) – Embu Research Centre, during the long rains (LR) 2021, and short rains (SR) 2021/2022. A factorial experiment with a split-plot layout arranged in a completely randomized block design was adopted. The watering regimes (100 %, 60 %, and 30 % based on the field capacity (FC)) were the main factor while the sub-factor was the planting density, with three replications. The planting densities used were 0.5 m × 0.5 m (40,000 plants ha-1), 1 m × 0.5 m (20,000 plants ha-1), and 1 m × 1 m (10,000 plants ha-1), representative of high, medium, and low planting densities respectively. Proximate analysis and mineral content were determined. Results. Significant differences (P < 0.05) in seasons were noted for protein, fibre, potassium, calcium, sodium, and zinc in the taro corms. The high carbohydrate content observed in this study (35 – 39 %) indicates that taro tubers are a good source of nutritional energy. Potassium (> 5000 mg kg -1) and magnesium (> 1000 mg kg -1) were the most prevalent mineral elements in taro corms and leaves, with copper (< 25 mg kg -1) being the least prevalent. Implications. Consumption of nutrient-rich foods such as taro helps the body to utilize the necessary nutrients to combat malnutrition and promote food security in rural communities. Conclusion. Taro leaves can be recommended as leafy vegetables as they are good sources of potassium, magnesium, calcium, manganese, iron, copper, and zinc; and the corms have low fat and protein content, high calorific energy, and high carbohydrate content. Taro represents one of the main sources of energy in many parts of the tropics and its production can be recommended in sub-humid areas in Kenya.

“…A review on taro production by Alercia, (2013) showed that the taro root fat content usually ranges between 0.2 -0.7 %. Due to the low-fat percentages found in this study, taro corms could be recommended for lipidlowering and hypoglycemic diets as recommended by Koffi et al (2020).…”

“…Cultivated in tropical and sub-tropical humid regions (Chaïr et al [1]), taro, in Côte d'Ivoire, is dedicated to the edible varieties of Colocasia esculenta and genus Xanthosoma (Xanthosoma sagittifolium and Xanthosoma sp) (Sangaré et al [2]; Anon et al [3]; Koffi et al [4]; Koffi and Koffi [5]), even though taro countrywide diversity remains uncertainty (Gnangbé and Kouacou [6]; Koffi and Koffi [5]).…”

“…Taro is cultivated for all its parts (Boakye et al [7]) important in several utilizations. Corms and tubers play a very important role in food security: they are staple foods in certain regions (Akwee et al [8]; Koffi et al [4]; Ashish and Sing [9]). These corms are an important source of energy due to their high richness in starch than cassava and yam (Amani [10]; Bosson [11]; Amon et al [12]; Akwee et al [8] ; Romero et al [13] ; Ashish and Singh [9]).…”

The study was to determine the effects of variety, position and bud size on six parameters of taro development and production. For that, 480 tuber cuttings of three varieties (C1, C3, CD) of Colocasia and (X1, X4, X5) of Xanthosoma carrying small and large buds were sown in a complete randomized blocks design with two repetitions, in the University Félix Houphouët-Boigny (Côte d'Ivoire). The analyses showed that leaves of X5 emerged earlier (23 days). Also, leaves limb of X1, X4, X5 are longer (22 to 25 cm) and wider (20 to 25 cm) than those of C3 and CD (19 cm). Petioles and leaves are longer (51 and 74.25 cm, respectively) in X1. In contrast, Colocasia produced more tubers. Overall, bud of the top germinated earlier (26 days), generated longer (22.90 cm) and wider (22.54 cm) laminas and more tubers. Conversely, petioles and leaves from bud of the middle are longer. Also the large buds sprouted earlier (24.82 days) and generated longer (24.09 cm), wider (23.48 cm) laminas, longer petioles (45.32 cm) and leaves (69.43 cm). Furthermore, in individual varieties, on the one hand, plants grown from top buds presented the widest laminas (19.89 and 25.58 cm), in CD and X5, the longest petioles and leaves (41.44 and 67.83 cm) and, in addition, produced the greatest number (3.35) of tubers, in X5. On the other hand, large bud germinated earlier (25.20 days) in C3 and generated the longest laminas (19.71 to 26.84 cm) in the five varieties, wide (21.96 to 27.32 cm) in X1, X4, C3, the longest petioles (46.57 cm) in C3, longest leaves (61.30 to 79.73 cm) in C3, X1, X4 and the greatest number (3 to 6.23) of tubers in C3 and X4. All these findings should be exploited for better taro production.

“…Temesgen and Ratta (2015) have determined the content of nutrients in taro root, such as 26.8% glucid, 0.34% protein, 0.11% lipid, 2.5% crude fiber, 1.91% ash, 14.3 mg/100 g vitamin C, 0.028 mg/100 g vitamin B 1 , 0.029 mg/100 g vitamin B 2 , and 0.78 mg/100 g vitamin B 3 (Temesgen & Ratta, 2015). In addition, globally, some authors have studied the nutritional composition of taro tuber (e.g., Alcantara et al, 2013;Koffi et al, 2020). In Vietnam, up to this point, there are very few studies on physicomechanical, biochemical, and sensory indicators of taro tubers which have been published in scientific publications.…”

Taro tuber, which has the scientific name of Colocasia esculenta, is grown in Vietnam. The nutritional compositions of taro tuber are mostly starch, vitamin, protein, lipid, cellulose, and mineral. The purpose of this study was to determine the changes in physicomechanical, nutritional, and sensory indicators of taro tubers at different harvest times. The physicomechanical, nutritional, and sensory indicators of taro tubers were determined at three harvesting stages of 280, 300, and 320 days. As a result, the right time to harvest taro tubers is 300 days or more because taro tubers have fully developed in terms of size, weight, nutritional composition, and sensory indicators by this time. Specifically, at 300 days, taro tubers had a diameter of 5.6 cm and a weight of 71 g, with 69.83% water, 26.17% glucid, 2.82% protein, and 0.32% lipid. At the time of harvest of 300 days, 14 amino acids were identified, including 7 essential amino acids, namely, leucine, isoleucine, lysine, methionine, valine, phenylalanine, and histidine. Through the analysis of sensory indicators such as color, smell, taste, and texture of taro tubers, choosing the time to harvest taro tubers at 300 days for processing and storage is appropriate.
