Some Dietetic Factors Influencing the Market for Poi in Hawaii, with Emphasis on a Survey of the Use of Poi by the Medical Profession and Allied Institutions
(University of Hawaii, 1952-07) Derstine, Virginia; Rada, Edward L.
The bulletin is a thorough review of the nutritional qualities of poi, particularly as a food for babies, convalescents, and people with digestive problems. The survey revealed that doctors in Hawaii are widely aware of these qualities. Tables summarize the survey responses and give the chemical and nutritional properties of poi. The idea that fermentation of poi reduces the bacterial load of the fresh product, and improves digestibility, was raised, but research was not available to confirm it, and the physicians surveyed lacked knowledge of this aspect.
Poi Consumption: Consumption of a Traditional Staple in the Contemporary Era, in Honolulu, Hawaii
(University of Hawaii, 1981-01) Begley, Bryan W.; Spielmann, Heinz; Vieth, Gary R.
A questionnaire explored poi usage, frequency of purchase, and purchasers' buying behavior. The report discussed relationships between socioeconomic variables and consumption patterns. Ethnic Hawaiians were likely to be the most frequent consumers of poi. The authors stated that in 1828 poi was a staple for perhaps 95 percent of the population of Hawaii, and it was still an important food 100 years after that, but at the time of writing it was regularly consumed by only 5 percent or less of the population. The authors speculated that unless changes were made in its form, packaging, and promotion, a package of poi "could become an anachronism." Their prediction that "if poi is to have a profitable and lasting future then the flavor of the bulk of poi must change" had not been borne out in the several decades following the report's publication.

The Manufacture of Poi from Taro in Hawaii: With Special Emphasis upon Its Fermentation
(Hawaii Agricultural Experiment Station, 1933-11) Allen, O.N.; Allen, Ethel K.
The bulletin reviews the history and present conditions of taro culture and poi making in Hawaii and discusses the preparation of poi from the bacteriological standpoint.
Taro Industry Analysis Number 4; Submitted to the Governor's Agriculture Coordinating Committee
(University of Hawaii, 1990-08) Hollyer, J.R.; de la Pena, R.S.; Rohrbach, K.G.; LeBeck, L.M.
The analysis examined the state of the Hawaii taro industry, including its history, the current market in Hawaii and in North America, and its current status and potential. Action plans addressed industry bottlenecks, indicated the impacts on the industry if a bottleneck were or were not eliminated, and identified the action(s) required and the agency (or agencies) responsible for eliminating the bottleneck. Participants in the analysis, including university and state agency personnel, taro growers, poi millers, and marketers, prioritized the bottlenecks so that the Governor's Agriculture Coordinating Committee could decide how best to direct available funds.

Hawaiian Kalo, Past and Future
(University of Hawaii, 2007-02) Cho, John J.; Yamakawa, Roy A.; Hollyer, James
The arrival of taro in the Hawaiian Islands, its significance in Hawaiian culture, and the decline in its production since the early to mid-1800s is discussed. The university's role in preserving Hawaiian taro varieties is described, along with recent taro breeding programs conducted by its scientists.
Pesticides Currently Registered for Use in Taro in Hawai'i (2007)
(University of Hawaii, 2007-09) Anonymous
Herbicide, insecticide, and fungicide products registered for use on flooded or non-flooded taro crops in Hawaii in 2007 are discussed.
Nutrient Deficiences and Excesses in Taro
(University of Hawaii, 2002-07) Miyasaka, Susan C.; Hamasaki, Randall T.; de la Pena, Ramon S.
The publication provides a key to taro nutrient disorders, identifies the leaf to sample for nutrient analysis, gives nutrient concentrations associated with deficiency, sufficiency, and toxicity, and illustrates symptoms of nutrient deficiencies and toxicities in taro leaves and roots.
Impact of Organic Inputs on Taro Production and Returns
(University of Hawaii, 2001-07) Miyasaka, Susan C.; Hollyer, James R.; Cox, Linda J.
A field experiment evaluated effects of organic inputs on crop yield and quality and incidence of pocket rot, which commonly diminishes non-flooded taro yields by a quarter to a third. Considering the costs of organic inputs, enumerated in the publication, yield increases due to the amendments were not economically justified, at least in the short term; the experiment did not continue in order to assess long-term benefits and economics.
Improvements in Taro Culture and Reduction in Disease Levels
(University of Hawaii, 2002-08) Uchida, Janice Y.; Silva, James A.; Kadooka, Chris Y.
Causes of pocket rot and other fungal infections of taro corm are discussed. Careful attention to planting only disease-free huli (propagules) is emphasized.

Effects of different levels of N, P and K fertilization on the growth and yield of upland and lowland taro (Colocasia esculenta (L.) Schott, var. Lehua)
(University of Hawaii at Manoa, 1967) De la Pena, Ramon S (Ramon Serrano), 1936
Nitrogen, phosphorus and potassium were applied separately from 0 to 1120 kg/ha to upland and lowland taro. A 2 x 2 x 2 N-P-K interaction experiment was also conducted in pots using 0 and 15 grams of each element per plant. Nitrogen fertilization increased the N contents of the taro leaves but decreased both the P and K contents. Applications of P fertilizer increased the P content in the leaves but decreased the K content. Potassium fertilization increased K and decreased Ca and Mg contents of the taro leaves. The N content of upland taro leaves increased with K fertilization but the N content of the lowland taro leaves decreased. Potassium in the leaves of lowland taro regardless of treatments was lower than the K content of upland taro due to the higher Ca and Mg contents of the lowland soil. Both upland and lowland taro plants exhibited luxurious P and K consumptions. The N, P, and K contents of the leaves, regardless of treatments, decreased with age ..• The total N content of the soils was negatively related to the N fertilization, while soluble P and exchangeable K were directly related to the rates of P and K fertilizers applied. Yields of both upland and lowland taro were significantly increased by N and P fertilization. Potassium fertilization increased the yields of upland taro only. Delayed harvesting up to 15 months increased the yields of lowland taro, while yields of the upland taro at 12 to 15 months old did not differ significantly. In the lowland taro, the significant yield increase due to fertilization was attributed to the increase in number and weight of the sucker corms. In the upland taro, however, yield differences among fertilized plots were attributed to the main corms. Nitrogen fertilization decreased the density of both upland and lowland taro corms significantly. Phosphorus fertilization did not have significant effects on the corm density. Potassium fertilization increased the corm density, especially in the lowland. Protein content of the corms of upland and lowland taro which were fertilized with N increased by 53.5% over the control. In the pot experiments, the increase in protein content was 250%. The P and K contents of the corms also increased with P and K fertilization. In the pot experiment, only N fertilization gave significant increases in the weights of the corms, roots and leaves of the plants. Nitrogen deficiency was observed in all plants which did not receive N fertilization. Analysis of the leaves showed that plants which received N had an average of 2.8% and 4.6% N in the petioles and blades, respectively, compared with 1.1% and 3.3% N in the petioles and blades of plants without N fertilization. No P and K deficiencies were observed. The N, P, and K contents of the individual leaves showed a tendency to decrease from the youngest leaf to the oldest, except for P which increased from the youngest to the oldest when the P supply was not limiting. Results of the experiments showed that soil and plant analysis can be used to evaluate the fertilizer requirements of taro. In soil analysis, however, other methods of extracting soil N should be used to give a reliable index for the N requirement of taro.
Propagating Taro by the Normally Dormant Buds Present on Huli and Corm
(University of Hawaii, 1941-05) Kikuta, K.; Parris, G.K.
Rapid multiplication of taro plants by using corm sections was explored. Normally dormant buds on the corm can be stimulated to grow, and plantlets can be obtained from corm sections containing one of these buds. Buds on the upper part of the corm (the youngest part) were more readily stimulated to grow. Plants from corm sections grew as well as those from huli, but plants from huli were more uniform in growth.
The Economics of Commercial Wetland Taro Production in Hawaii
(University of Hawaii, 1994-04) Fleming, Kent
Taro is an important staple throughout the world, but taro, and especially wetland taro, is a particularly important crop in Hawaii because of the long historical tradition of growing taro in Hawaii and because of the deep Hawaiian cultural associations with the plant. The demand for taro in Hawaii exceeds the domestic supply, and there appears to be growth potential for the industry. However, the economics of this crop are as complicated as those of any other agribusiness enterprise. An economic model of wetland taro production for poi processing is developed in order to estimate typical and specific economic profitability. An analysis of the break-even price and yield and an analysis of the value of and return to various productive resources helps one to interpret the cost of production results. No attempt is made to quantify other positive attributes of wetland taro production, such as the crop's significant cultural and historical importance.
