Performance of Selected Coconut Varieties/ Hybrids Under Sequential Coconut Toddy and Nut Production Scheme or SCTNP

Abstract

The response to sequential coconut toddy and nut production (SCTNP) scheme of four coconut varieties/hybrids at PCA-Zamboanga Research Center, San Ramon, Zamboanga City showed that the dwarf x tall hybrids, Malayan red dwarf x Baybay tall (MRD x BAYT), Malayan red dwarf x Tagnanan tall (MRD x TAGT) and Catigan green dwarf x Laguna tall (CATD x LAGT) produced significantly higher toddy (495 – 699 li/tree/yr) and nut yield (143-169 nuts/tree/yr) compared to tall cultivar, ‘Laguna’ LAGT (364 li and 123 nuts per tree per year). Varietal difference in terms of the floral and vegetative characteristics of the coconut cultivar and hybrids contributed significantly to the differences in the sap/toddy and nut yields.

An Investigation of Yield and Quality of Coconut Inflorescence Sap in Different Coconut (Cocos nucifera L.) Genotypes under West Coast of India

“…Since significant differences in the number of leaves on the crown and inflorescence length and circumference were observed and these parameters may contributed to the differences in sap yield of coconut genotypes (Table 3). Secretaria et al, (2002) emphasized that the palms which have more number of living fronds on the crown have the tendency to have more sap yield, because every living frond of bearing palms has a natural capacity to support a spathe which can be used for tapping. He also reported that floral structure especially the length of the inflorescence is a good indicator for higher sap since longer spathe implies longer spikelets and flowers which are contained inside the spathe and could be the source of sap from the spathe.…”

“…Konan et al, (2013) reported a positive correlation between the yield of sap and the length and median circumference of the spathe. Secretaria et al, (2002) studied six coconut varieties and reported that the length and girth of the inflorescence influence the sap production since inflorescence component characters viz., number and length of spikelets and number of buttons (female flowers) decide the length and median circumference of the inflorescence and these component characters could be the source of sap from the spathe. He also reported that the palms which have more number of leaves have the tendency to have produce more sap yield because every living leaves of bearing palms has a capacity to Support a inflorescence for sap production.…”

Commercial Production and Chemical/Physical Characterization of Natural and Nutritious Coconut Sap Food Products (Cocosap Juice and Cocosap Concentrate) at Tawan-tawan, Baguio District, Davao City, Southern Mindanao, Philippines

“…Experimental palms: Local coconut hybrid, Catigan green dwarf X Laguna tall (CATD x LAGT) palms planted at the coconut areas of the members of Samahang Magniniyugan ng Tawantawan (SMT) were used for the tapping of coconut sap. CATD x LAGT hybrid had been found to be one of the identified high yielding (coconut sap and nut producing) coconut hybrids and varieties in the country (Secretaria et al, 2002). About 50 trees or at least 0.50 ha of coconut palms were tapped for the production of coconut sap to be processed into cocosap juice and cocosap concentrate.…”

On-Farm Production and Processing of Selected Coconut Sap-Based Natural and Nutritious Food Products From SCTNP Scheme

“…This scheme has been successfully done in 'Laguna' tall and Malayan yellow dwarf x West African tall ('MAWA') hybrid coconuts and proved feasible and profitable (Maravilla and Magat, 1993). Likewise, its application has been proven more profitable in local hybrids such as Catigan dwarf x Laguna tall (CATD x LAGT), Malayan red dwarf x Baybay tall (MRD x BAYT) and MRD x Tagnanan tall (Secretaria et al, 2001;2002).…”
