The Carbon Stock of Mango Plantation Based on the Above Ground Biomass
Content at DMMMSU-NLUC, Sapilang, Bacnotan, La Union was assessed in this study. The study was conducted from April 27, 2019 to May 7, 2019 at the Mango project with an area of 2,150 square meters. The descriptive statistics such mean and frequency count with 100% sampling intensity were used to assessed 73 mango trees with 10cm and above diameter at breast height (dbh). The basal diameter of mango tree ranges from 25 to 52 cm were classified into basal diameter class 30, 40 and 50 (cm). There are 61 trees (83.56%) were characterized as forked stem and 12 trees (16.44%) as unforked stem. The result showed that the highest tree biomass was obtained by the diameter class 20 cm with 19,141.6 kg, while the lowest tree biomass was obtained by the diameter class 10 cm with 871.2 kg, for both forked stems. Moreover, the forked stem showed 34,815.4 kg total biomass higher than unforked stem with 7,278.6 kg. The total carbon stock of the mango tree plantation was 18.94 tons with 15.66 tons and 3.28 tons for forked stem and unforked stem, respectively. In addition, the highest carbon stock was recorded in the mango tree with diameter class 20 cm while the diameter class 10 cm recorded the lowest carbon stock amount. Thus, the study revealed that mango plantation has 88.09 tons of carbon stock per hectare that would sequester 2.11 tons of carbon per year.
Development of calabash (Crescentia cujete) juice drink
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2023-05) Licos, Janina May M.; Costales, Suzette C.; Villamil, Krisha Shane L.; Alvarez, Sheila B.; Estabillo, Imma Concepcion G.; Pacada, Charles A.; Abat, Rossana P.
This study is to develop a calabash juice drink. Specifically, it aims to, (1) standardize the formulation and process of calabash juice drink. (2) Determine the sensory qualities of a calabash juice drink. (3) The production cost of processing of calabash juice
drink. Four (4) treatments were formulated based on varying the amount of calabash extract. The treatments have undergone sensory evaluation tests such as ranking, preference, descriptive and acceptability tests. Treatment 2 was the most preferred calabash juice drink. The juice drink was perceived to be blackish gray, has a strong aromatic and sweet odor, very strong sweet and slightly sour flavor, and very smooth texture. In acceptability test, the flavor and texture of the calabash juice drink were perceived as like extreme. However, the calabash juice drink had received general acceptability as like very much. Microbiological analysis shows that the calabash juice drink has a mold and yeast count of <10cfuml and an aerobic plate count of <250cfu/ml. The presence of phytochemicals like flavonoids, alkaloids, carbohydrates, and phenolic compounds was observed. Vitamin C was not detected in the calabash juice drink.
Plant species diversity of Mangrove sites in the Province of La Union
(Don Mariano Marcos Memorial State University - North La Union Campus, 2017-06) Leaño, Ben Joseph G.
This study was conducted to determine the species composition, structure and diversity of the different mangrove sites in the Province of La Union.
The different mangrove sites assessed were predetermined using Google Earth and ground validated using Global Positioning System. Quadrant sampling was used to assess the different vegetation within the mangrove sites.
It was found that there are a total of 12 mangrove species in 13 different municipalities of La Union. These are Bakawan babae, Apiapi, Culasi, Bakawan lalaki, Pototan, Saging saging, Pagatpat, Buta-buta, Busain, Mangrove Trumpet Tree, Palaypay and Bakawan bato. Bakawan babae was the most common mangrove species found in the mangrove sites while bakawan bato was the rarest species in the mangrove sites. Pagdalagan was found to be the most diversed mangrove site in the province of La Union. There were 6 species found in the area, namely, Pototan, Bakawan babae, Culasi, Bakawan lalaki, Api- api and Busain. The most dominant
mangrove species found in Baccuit was Pototan, (Biday) Saging saging,(Catbangen) Bakawan babae, (Darigayos)Bakawan babae, (Galongen) Bakawan lalaki, (Ili Norte) Palaypay, (Pagdalagan Sur) Pototan, (Paraoir) Culasi, (Pudoc and Sto Rosario) Api api, (Sta. Rita West) Pototan and (Sto.Tomas and Taboc) Bakawan babae.
Assessment of Agroforestry technology awarenes and adoption in shifting cultivation areas at Candon City, Ilocos Sur
(Don Mariano Marcos Memorial State University - North La Union Campus, 2017-06) Ganapin, Vincent V.
This study was conducted to assess the level of awareness and adoption of agroforestry technology in shifting cultivation areas of Candon City, Ilocos Sur. The study was conducted from January to March 2016 along shifting cultivation area managed by respondents from Barangay Palacapac, San Andres, Cubcubuot and Santo Tomas at Candon City province of Ilocos Sur. The assessment was carried out using survey questionnaire. Result of the study showed that most of the respondents are male aging 41 years old and above who are high school graduate.
The awareness level of the respondents under agrisilviculture, and shifting cultivation is high same with fuel wood production. In taungya awareness level is low same with alley cropping, multilayer tree garden, multipurpose trees on crop land, plantation crop combination, trees in soil conservation, shelterbelt and windbreaks hedgerows. There was moderate awareness in
homegardens. There was a low awareness under silvipastoral, in trees and shrubs on a rangeland or pasture land. Protein banks and plantation crops with pasture or animals, while in love fence of fodder and shrubs has a moderate level of awareness. Under agrisilvipastora system, in home gardens including animals there was a moderate awareness, while in multipurpose woody hedgerows there was a low level of awareness. Under other technologies such as apiculture with trees has a moderate level of awareness while in multipurpose woodlands there was a low level of awareness.
The adoption level of the agroforestry technologies, was very low under agrisilviculture, in shifting cultivation, apiculture with trees and multipurpose woodland, while taunga has a low level of adoption, same with alley cropping, multilayer tree garden, multipurpose trees on crop land, plantation crop combination, trees in soil conservation, shelterbelt windbreaks, and hedgerows. Home gardens and fuel wood production has a moderate level of adoption. There was a low level of adoption under silvipastoral system, trees and shrubs on rangeland and pasture land has a low level of adoption same with protein banks, plantation crops with pasture and animals, and living
fence of fodder and shrubs. There was a low level of adoption in multipurpose woody hedgerows.
The respondents integrated tree crop such as madre cacao, ipil-ipil, mahogany, yemane, mango, narra, tamarind, nangka and chico together with rice, tobacco, corn, vegetable crops, peanut and dragon fruit. The respondents also integrated animals like cattle, goat, chicken, swine and duck in their farm.
There are benefits that can be derived from adoption of agroforestry technologies such as: generates more income, can lead to diversified harvest, and for erosion control. Some of the problems encountered by the farmers are laborious, lack of financial assistance, lack of skills in farming and no ownership of the land.

The study was conducted to determine the growth, yield and net income of bell pepper varieties as intercropped with duhat, growth of the duhat trees and climatological data during the conduct of the study.
The research was conducted at the Agroforestry Research and Demonstration Farm (ARDF), Institute of Agroforestry and Watershed Management (IAWM), DMMMSU-NLUC, Bacnotan, La Union from December 15, 2016 to March 24, 2017.
Randomized Complete Block Design (RCBD) was used with the fallowing
treatments: V1- Kalahari variety, V2 - Sultan variety and V3 - Emperor variety.
Results revealed that Sultan variety was the tallest with 7.16 cm the latest to
produced flower from planting with 39.57 days, the earliest to anthesis from flower emergence with 1.43 days, to fruit emergence from anthesis with 1.71 days, to harvesting from fruiting with 1.43 days, highest yield per plot with 10.26 kg and per hectare with 1.75 tons, and net income per plot with Php 1,507.24 and per hectare with Php 155,868 than the other varieties.
Highly significant difference in all parameters taken were observed except on the final height which is not significant and the production of branches.
The growth of duhat was increased with 0.30 m high, 0.36 m crown diameter and 2.20 mm stem diameter during the conduct of the study.
