Cotton plays an important role in increasing productivity in the agricultural sector and related industries in the province of Golestan, Iran. However, the cultivation areas decreased considerably in the last couple of decades due to the high costs of production, water scarcity, and climate change. To encourage sustainable increase in production, crop simulation models are parameterized for each region using observed field data. In this study, the AquaCrop model was calibrated and validated for cotton under different field management scenarios using data from a 3-yr field experiment, which was conducted at the research farm of the National Cotton Research Institute, …
Taxonomy Of Cassava (Manihot Esculenta Crantz) Mealybugs (Hemiptera: Pseudococcidae) - 1: Identification And Local Distribution Of The Predominant Species On Witches’ Broom-Diseased Plants In The Philippines, Ireneo L.

Taxonomy Of Cassava (Manihot Esculenta Crantz) Mealybugs (Hemiptera: Pseudococcidae) - 1: Identification And Local Distribution Of The Predominant Species On Witches’ Broom-Diseased Plants In The Philippines, Ireneo L. Lit Jr., Cristian Lucañas, Joanne Langres, Lolita Dolores, Ruby Ana Laude, Merdelyn Caasi-Lit

Samples of cassava (Manihot esculenta Crantz) plants infected with witches’ broom disease were gathered from 13 provinces in the Philippines. Mealybugs were observed to occur in nine out of the 13 cumulative samples. The most predominant among several mealybug species observed was identified as Pseudococcus jackbeardsleyi Gimpel and Miller. P. jackbeardsleyi is not yet known to transmit phytoplasma, especially the one causing cassava witches’ broom (CWB). However, its occurrence in almost 70% of the CWB-infected samples provides circumstantial evidence that it may be related to the spread of the pathogen. This formal report of identification is in support of the …
Application Of The Analytic Hierarchy Process And Geographic Information System In Selecting Sites For A Seafood Market Study, Shielameh Peralta-Milan, Osamu Baba, Severino Iii Salmo
Application Of The Analytic Hierarchy Process And Geographic Information System In Selecting Sites For A Seafood Market Study, Shielameh Peralta-Milan, Osamu Baba, Severino Iii Salmo

Study site selection is essential for the success of many fisheries-related programs. A thorough site selection could provide transparency in the decision-making process and optimize resources. In this research, the analytic hierarchy process (AHP) approach was used to select sites for a market study of reef-associated seafood in Alaminos City, Northwestern Philippines. Out of the 10 coastal barangays, four (Lucap, Sabangan, Telbang, and Victoria) were initially chosen, and the difference between these sites and the priority sites generated from AHP was examined. Five decision criteria and 10 alternatives (coastal barangays) were analyzed to calculate priority weights using pairwise comparisons. The …
Effects Of Redrying Methods On The Milling Potential, Crude Protein And Total Phenolic Content, And Antioxidant Activity Of Stored Inorganic And Organically-Grown Paddy, Mary Ann Baradi, Jessica Solero, Clarence Dangcil, Gerome Corpuz, Marissa Romero
Effects Of Redrying Methods On The Milling Potential, Crude Protein And Total Phenolic Content, And Antioxidant Activity Of Stored Inorganic And Organically-Grown Paddy, Mary Ann Baradi, Jessica Solero, Clarence Dangcil, Gerome Corpuz, Marissa Romero

This study sought to determine the effects of redrying techniques (no redrying or Control, 2-h, 4-h, and 6-h redrying with stirring every 30 min, Farmer's Practice or 6-h redrying with one stirring) on grain quality of stored inorganic and organic paddy rice as well as the redrying method that gives the best quality rice. PSB Rc82 rice harvested in October 2016 was used in the experiment conducted in February 2017. Quality parameters evaluated were moisture content, brown rice, total milled rice, crude protein content in percent, total phenolic content, and 2-2 diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. PSB Rc82 paddy exposed …
Method For Calibrating An Arduino-Based Soil Moisture Sensor Using Van Genuchten’S Equation, Victorino A. Bato, John Osbert Alindogan
Method For Calibrating An Arduino-Based Soil Moisture Sensor Using Van Genuchten’S Equation, Victorino A. Bato, John Osbert Alindogan

Instructions on building a do-it-yourself soil moisture sensor using Arduino microcontrollers abound on the Internet. These do-it-yourself soil moisture sensors are favorite projects by both plant and microcontroller enthusiasts because the parts are affordable and the end product is functional. In the absence of proper calibration, these soil moisture sensors cannot generate usable information on the status of plant-available-water in the soil. This research demonstrates the calibration of an Arduino-based soil moisture sensor using the soil moisture characteristic curve of a clay loam soil. Van Genuchten’s model was used to generate an equation and various parameters specific to the soil. …
Feeding Behavior Of Sweet Potato Weevil, Cylas Formicarius (Fabricius) (Coleoptera: Brentidae) On Three Sweet Potato, Ipomoea Batatas L. Cultivars Grown In Tarlac, Philippines, Jerah Mystica Novenario, Flor Ceballo-Alcantara
Feeding Behavior Of Sweet Potato Weevil, Cylas Formicarius (Fabricius) (Coleoptera: Brentidae) On Three Sweet Potato, Ipomoea Batatas L. Cultivars Grown In Tarlac, Philippines, Jerah Mystica Novenario, Flor Ceballo-Alcantara
The Philippine Agricultural Scientist
Sweet potato is grown in tropical countries for its edible tubers, which have become an essential food source. It is usually propagated through vine-cutting, which can be obtained from harvested plants or nurseries intended for cutting production only. The recurrent use of vines may cause increased weevil infestation. The crop is known to be infested with insect pests. More importantly, the sweet potato weevil, Cylas formicarius, targets the tubers, thus, causing the economic losses. Sweet potato farmers in Tarlac claim that only one sweet potato cultivar is being attacked by C. formicarius, however, it was found in this experiment that …
