Cultivars in Côte d’Ivoire0 aAssessment of Sap Production Parameters From Spathes of Four Coc3 a

Several palm plants have social and economic roles worldwide by providing drinks from their sap. In Côte
d’Ivoire, management of the coconut sap is not yet practiced. In this study, parameters related to production of
sap have been assessed from four coconut cultivars namely PB 113+ and PB 121+ hybrids and WAT and MYD
varieties. From all the unopened inflorescences (spathes) studied into the coconut crown, whose ranks varied
from 7 to 9, that of rank 8 yielded the highest volume of sap. From this spathe, the PB113+ hybrid provided the
best yield of sap (61.81 ± 20.41 l). Most important proportion of that sap volume was recorded at the morning
harvesting. The sap production duration of a spathe varied from 24 ± 1.87 days (MYD) to 46.78 ± 1.86 days (PB
113+). That duration depended on the length of spathes and regular sap flow allowed by them. Furthermore, the
PB 113+ had the highest number of fruits (NBF = 174.33 ± 78.45 fruits). The results showed that volume of sap
available is closely related to the length of production (r = 0.78) and the cultivar’s nut yield (r = 0.82). The use of
PB 113+ hybrid which provided highest quantity of sap is recommended for promoting the production of coconut
sap in Côte d’Ivoire in order to improve the benefits derived from this plant.

Methods of tapping the nipa palm (Nipa fruticans Wurmb.) were developed in the course of a 3-year study conducted in seven villages in the Baimuru district of the Gulf Province of Papua New Guinea. The experimental sites were located about 1.5–23 km from the sea. Their plant density varied from 4700 to 2400 palms per ha and the mean height of the plants was nearly 13 m. Five pre-treatment patterns were tested. Once-a-week treatment, maintained for 12 weeks, yielded an average of 155 ml of sap/24 h/palm for one month, whereas 3–5-times-a-week treatment, for 5–12 weeks, yielded an average of 1300 ml of sap. The duration of treatment depended on the state of development of the flower stalk. The pre-treatment pattern chosen as the standard was to bend the stalk 12 times in one direction, to pat with the hands the length of the stalk backwards and forwards 64 times, and to give the base four kicks; this was repeated four times a week. In the course of the 3-year study it was found that the average sugar content of fresh nipa sap is rather high, about 16.4% w/v, as compared with, for example, about 12% w/v of sugar cane. The results of the present study are discussed with reference to producing fuel alcohol from the Papua New Guinea nipa palm.
