Growth and survival of cacao (Theobroma cacao L.) var. uf-18 as influenced by planting distance and manure tea planted in cacao-based agroforestry system
(Don Mariano Marcos Memorial State University- North La Union Campus, 2024-06) Toralba, Elmer Q.; Oblero, Ardy D.
The study was conducted to determine the effects of planting distance and fermented manure tea on the growth and survival of cacao seedlings 120 days after planting. This study was conducted at the Cacao-Based Agroforestry System of Don Mariano Marcos Memorial State University - North La Union Campus Bacnotan, La Union. A total of 216 three-month-old UF-18 cacao seedlings were used. The study was laid out using the Split-Plot Design with three replications. Results of the study showed that the planting distance and fermented manure tea used had no significant effect on the growth of cacao, and the survival percentage rate ranged from 72.33% to 100%, The climatological data such as temperature (C₀), rainfall (mm), and relative humidity (%) favored the growth and survival of cacao
seedlings.
Growth and yield of tomato var. diamante max f1 (Solanum lycopersicum L.) as affected by different planting distance and organic foliar fertilizers in a multi-storey agroforestry system
(Don Mariano Marcos Memorial State University- North La Union Campus, 2024-06) Balisbis, Cynthia T.
This study investigates the optimization of tomato cultivation within agroforestry systems. It aimed to evaluate the growth and yield of tomato var. Diamante max f1 as applied with organic foliar fertilizers at different planting distances in a multi-storey agroforestry system. The study was laid out following a Split Plot Design with three blocks and thirty-six plots. Planting distance of 70cm x 80cm gave the most favorable results in terms of growth and yield of Tomato var. Diamante Max F1. Plants applied with Fermented Plant Juice(B3) produced the highest gross income, and all the plants survived 100% at the termination of the study. Interaction effects between planting distance and organic foliar fertilizers on the days of harvesting revealed that Tomato var. Diamante Max F1 plants applied with Fermented Fruit Juice (B2) at planting distance of A2 (60cm x 80cm) were the earliest to harvest with an average of 102.67 days and produced the earliest days to fruiting.
Effects of kakawate (Gliricidia sepium (Jacq.) Kunth ex Walp.) biochar and oyster lime soil amendments on the early growth of banana var. lakatan (Musa acuminata Colla) plants under acidic soils
(Don Mariano Marcos Memorial State University- North La Union Campus, 2025-05) Bambao, Jamaica L.; Gapasin, Ryan B.
Acidic soils limit banana (Musa acuminata Colla) production by reducing nutrient availability and
degrading soil structure, leading to poor growth and survival of tissue cultured banana var. Lakatan. Organic soil amendments like Kakawate biochar and Oyster lime have potential to improve acidic soil conditions, but their specific effects under nursery conditions remain underexplored. This study evaluated the effects of Kakawate biochar and Oyster lime on the growth and survival of tissue-cultured banana var. Lakatan in acidic soils under nursery conditions.
A Randomized Complete Block Design with three replications and five treatments was employed: T₀ – acidic garden soil (100%), T₁ – acidic garden soil (100%) + complete fertilizer, T₂ – acidic garden soil (50%) + Kakawate biochar (50%), T₃ – acidic garden soil (50%) + Oyster lime (50%), and T₄ – acidic garden soil (50%) + Kakawate biochar (25%) + Oyster lime (25%).
Results showed beneficial increase of soil pH and organic matter, and optimum exchangeable magnesium in amended acidic soils. Kakawate biochar significantly enhanced plant height, pseudostem diameter, number of leaves, leaf length, leaf area, number of roots, root and shoot fresh weight, and root dry weight. The highest survival rate was observed in plants treated with Kakawate biochar. Positive correlations among growth parameters indicated consistent plant responses under improved soil conditions.
These findings demonstrate that Kakawate biochar is an effective, sustainable amendment for improving the early growth and survival of banana var. Lakatan in acidic soils under nursery conditions.
Development of Pinakbet kropek
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2026-05) Parba, Marc Anthony Louis D.; Delos Santos, Lourene France J.; Mundala, Irish Ann B.; Fernandez, Jerald B.; Estabillo, Imma Concepcion G.; Estabillo, Imma Concepcion G.; Alvarez, Sheila B.; Damaso, Pauline T.; Pacada, Charles A.
This study developed and evaluated the acceptability of Pinakbet Kropek as a nutritious alternative snack. It aimed to standardize formulation and processing methods and assess sensory characteristics, physicochemical properties, microbiological quality, packaging, labeling, and production cost. Four formulations using different ratios of taro starch and cassava starch ratios (60:40, 70:30, 80:20, and 90:10) were tested. Treatment 4 (90:10) was identified as the most preferred based on evaluations by consumers and trained panelists. It was described as light brown, slightly salty, with a sligh fish and pinakbet flavor, very crunchy, and a moderately hard texture. Physicochemical analysis showed moisture (9.31 g/100 g), ash (0.153 g/100 g), fat (1.14 g/100 g), protein (2.72 g/100 g), fiber (0.23 g/100 g), carbohydrates (86.45 g/100 g), and water activity (0.584). Microbiological results met safety standards with low counts of bacteria, coliforms, molds, and yeasts. Production cost was Php 40.25 per 100 g pack, indicating potential market viability in local markets in the future.
Local government efficiency in the Second District of La Union
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2019-05) Dumo, Jamela G.; Gajisan, Abygail M.; Pagaduan, Rhea Mae O.; Palaroan, Lesliee Ann H.; Sabado, Jennifer M.; Solim, Maybel P.; Legaspi, Annaliza B.; Perez, Estrella N.; Ancheta, Marifel D.; Pajimola, Allan Hil B.; Bayani, Keneth G.
Efficiency is measured through productivity. Using the ten indicators of government efficiency of the National Competitiveness Council (NCC)such as compliance to national directives, presence of investment promotion unit (IPU), business registration efficiency, capacity to generate local resource, capacity of health services, capacity of school services, recognition of performance, compliance to BPLS standards, peace and order and social protection, employing data capture sheet as main gathering tool and validated through documentary reviews, this study found out that LGUs in the second district cannot fully deliver the different social services needed for their constituents with the highest form of efficiency as they are impeded with limitations particularly resources within their capacity and insufficient internal and external supports from the national government. Nonetheless, these LGUs are trying their best to provide the best government transaction experience guided by the different laws relative to government efficiency.
