CARBON STOCKED AND CARBON DIOXIDE SEQUESTERED
BY EIGHT-YR ALNUS (Alnus japonica)
Lanie C. Paran and John G. Tacloy
College of Forestry
Benguet State University
ABSTRACT

The amount of carbon stocked and carbon dioxide sequestered by eight-year old
Alnus trees were estimated using a destructive sampling method. The carbon contents were
computed using the published average values for tropical trees which is 45% – 50%
of dry matter and the CO sequestered was computed based on the published CO to C
2
2
ratio which is 3.6663. The research was conducted in May 2012 at an Alnus stand at the
BSU-College of Forestry, La Trinidad, Benguet.

The average above-ground biomass (AGB) and below-ground biomass (BGB) of
the Alnus trees was 140.99 kg per tree, and their average oven-dry weight was 70.91kg
per tree. The AGB was 71.56%, and the BGB was 28.44% of the total biomass. The
computed biomass of the Alnus trees using a published formula is much lower; their
average AGB is 24.665%, their BGB is 12.58%, and their total computed biomass is
21.18% of the actual biomass.

Based on the oven-dried weight data, the computed average carbon contents of the
Alnus trees was 31.91kg per tree, and the average carbon dioxide they sequestered was
116.999kg per tree in eight-years, or an average of 14.63kg per tree per year.

Base on the findings, Alnus trees can approximate or exceed the published average
CO sequestration rate for mature trees which is 48lb per year. Further, a hectare Alnus
2
plantation with an average of 2m x 2m spacing cansequester about 292.6 tons of CO2
in eight years, or an average of 36.575 tons of CO per year which is equivalent to the
2
CO emissions of about 16 persons.

ABSTRACT

Twelve sweet potato entries namely; J06-11-10, JK 18-4, JK 7-4, JK 23-1, J06-30-3,
JK 06-11-12, SG 02-07-05, SG 02-05-01, SG 02-05-01, SG 98-16-02, SG 03-09-01,
SG 02-06-02, SG 02-13-02 and two (2) check varieties NSIC 30 and NSIC 31 were
evaluated for its yield performance and acceptability under La Trinidad conditions for
dry and wet season trials from 2009-2011.

Results showed that SG 02-07-05, SG 98-16-02, J06-11-10 had the highest yield
with 24.18 t ha-1, 22.39 t ha-1 and 20.04 t ha-1 respectively. SG 02-07-05 significantly
outyielded the check variety NSIC 31. Based on the sensory evaluation J06-11-
10 was the third top highest yielder. SG 02-05-01, JK 18-4, JK 7-4, SG 02-06-02,
JK 23-1, J06-30-3, SG 02-13-02, (NSIC 20 as check variety) were found highly
acceptable with rating of 7-like very much. The highest dry matter content of
35% was recorded by JK 18-4 and JK 23-1. Most entries are ridgedly deformed.
Keywords: camote, natural saver, famine crop, acceptability

SWEETPOTATO PRODUCT DEVELOPMENT: MODIFIED
YOGHURT, HOPIA AND VINEGAR

ABSTRACT

Three sweetpotato entries namely JO6 30-3 (yellow colored flesh), Immitlog (orange
colored flesh) and Haponita (violet colored flesh) were evaluated for their acceptability
when added to yoghurt as flavoring hopia as filling and vinegar as fermenting material.
The product development was done from October 2010 to July 2013.The varieties were
found to be acceptable for the production of yoghurt, hopia and vinegar. Yoghurt and
hopia has good taste, sugar just right and texture is smooth for yoghurt. Sweetpotato
yoghurt can have a shelf-life of one month under refrigerated condition, hopia for seven
days under room temperature conditions ranging from 24 – 26 °C and relative humidity
from 70-80%.

Vinegar is acceptable at six months but has a better taste when aged longer, one year
or more with a pH of 3.4. Addition of yellow, orange and violet fleshed sweetpotato
increases energy, carbohydrates, vitamin A and calcium of yoghurt and vitamin A and
calcium of hopia.With an estimated production cost of Php 33.06, Php 25.78, and Php
23.98 for yoghurt, hopia and vinegar, the computed return on cash expense for yoghurt
is 25.52%, 25.10% for hopia and 25.13% for vinegar if the wholesale price is PhP 41.50
(yoghurt), PhP 32.25 (hopia) and Php30 (vinegar).

WEAVING FOR LIFE: DESIGNS AND MOTIFS IN THE INABEL OF
BONTOC WEAVER INFORMANTS IN BAGUIO CITY
Ruth S. Batani
College of Arts and Sciences
Benguet State University
ABSTRACT

Weaving and woven products in their present form have taken on
interesting transformations over the years. Among indigenous women in the city
of Baguio, weaving has taken on new energies with the invention of designs
and new colors while at the same time retaining the ethnic motif. Using key
informant interviews on Bontoc women weavers, the study draws attention to
the artistic output of the weavers that are responding to identity construction at
the same time satisfying market demands. Findings show that women weavers,
at least in their generation, despite the meaningfulness of traditional designs on
their woven fabrics, have also appropriated new designs and colors as part of
their negotiations in the market. Other institutional market demands have also
influenced the presentation of their woven products. Women weavers were able
to negotiate their ‘ethnic motif’ in the market, while at the same time meeting the
challenges of the exclusivist character of ‘ukay-ukay.’
Keywords: abel or inabel; ethnic motif
