Warren D. Come1, Eva Schlecht2 and Katja Brinkmann3 ABSTRACT The Batanes islands are few of the remaining preserved natural landscape and seascape areas in the Philippines. The major source of income in the islands is ruminant husbandry. The study was conducted to document and assess the traditional husbandry systems in these areas with the specific …
Moises Neil V. Seriño1,2 ABSTRACT This study aimed to estimate the carbon footprint of Philippine households from consuming various goods and services. Data from the Philippine Input-Output Table and Global Trade Analysis Project’s carbon emission coefficients were used to extract the carbon intensities of different economic sectors. The embodied carbon emission from different consumption items …
Roberta Dizon-Lauzon and Linda B. Mabesa ABSTRACT The essential oil of the aerial part of Coleus amboinicus showed antibacterial activity against Bacillus subtilis (gram +) and Pseudomonas fluorescens (gram -) and antifungal activity against Cladosporium cucumerinum. Bioassay-guided fractionation revealed that carvacrol and ß-caryophyllene-4,5-oxide were the major contributors to the antimicrobial activity of the essential oil. …
Anabella B. Tulin, Victor B. Asio, Dindo M. Campilan and Shigenao Kawai ABSTRACT The nutritional disorders in the leaves, shoots, and root systems of sweetpotato variety PSB SP-17 were evaluated using the solution culture technique. Nutrient deficiency symptoms were established for the following elements: nitrogen, phosphorus,potassium, magnesium, calcium, sulfur, iron and micronutrients. Thirty-six healthy stem …
D. L. S. Tan1, K. Miyamoto2, K. lshibashi3, K. Matsuda4 and T. Satow5 ABSTRACT The performance of the root crop processing machines used in the production of sweetpotato grates and flour was determined. The machines included the Philippine Root Crop Research and Training Center (PhilRootcrops) pedal-operated root crop chipper/ grater, hydraulic presser, spinner, motor-operated attrition …
Feliciano G. Sinon and Alberto C. Martinez Jr. ABSTRACT An electronic, portable, cheap and easy-to-operate moisture meter was developed and fabricated using the resistivity—conductivity principle of operation which states that the presence of moisture in the fiber conducts electrical current from one terminal end to the other. Its circuitry followed that of the modified wheatstone …

Manuel K. Palomar, Erlinda 0. Landerito, Avelina P. Molato, Doreen S. Cayanong and Victoria G. Palermo ABSTRACT Sequential extractions were done in selected botanicals to test their bioactivity against important fungal pathogens of root crops. Extracts considered as potential fungicide were ampalaya (Momordica charantia) crude ethanolic/acetonic extract to Colletotrichum gleosporoides and Phytophthora colocasiae, asyang (Mikania …

L. M. Diamante1, M. S. Chinnan2 and P. Mallikurjunan2 ABSTRACT A simple model based on Hukill’s Analysis was used in the simulation of deep bed drying of peanuts at various drying conditions. The model was first evaluated using published drying data and then actual drying experiments at different conditions. The results showed that the simulation …
L. M. Diamante1, Ken-ichi Ishibashi2 and Kazunori Hironaka ABSTRACT A study was conducted to determine the adsorption isotherms of dried mangoes at different temperatures. The results showed that the adsorption isotherms of dried mangoes at different temperatures were type III according to the BET classification. At a water activity <0.50,the equilibrium moisture content of samples …
