To address this, mushroom bed establishment, and adult fly sampling at different growth stages of V. volvacea mushrooms by net-sweeping and use of sticky boards were done at weekly intervals. Net-sweeping revealed catches of adult flies which were identified using appropriate taxonomic keys, but insects collected by sticky boards were mutilated and identification was not possible.Eight species of flies found exhibited the breadth of dipteran diversity; three families represented the suborder Nematocera (Scatopsidae, Sciaridae and Empididae) and five of the suborder Brachycera namely, Mycophila (Cecidomyiidae), Pipunculus (Pipunculidae), Porcenus (Heleomyzidae), Leptocera (Sphaeroceridae), and Desmometopa (Milichiidae). The most abundant fly was Desmometopa in the eight weekly samplings done signifying that the mushroom substrate is supporting this fly population. Desmometopa, as well as Porcenus and Scatopsidae flies are known detritivores while Sciaridae and Cecidomyiidae represented by Mycophila are known fungivores.. Pipunculus and the Empididae fly are endoparasite and predator, respectively.","PeriodicalId":379508,"journal":{"name":"CLSU International Journal of Science & Technology","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121446179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the mechanization index of the onion production in Nueva Ecija were computed at 0.715 or 71.5%, labor productivity at 1.375 kW/ha, and land productivity at 9.06 MT/ha. Meanwhile, major hindrances on mechanization of onion production in Nueva Ecija is the expensiveness of machines that are available in the market which is unaffordable to farmers who have small farm sizes. Thus, they prefer to borrow or rent machines to perform their farm operations. Land preparation, spraying, and irrigation are among the field operations that utilizes mechanical power. Whereas, transplanting, crop establishment, and harvesting are done manually. This situation requires the farmers to hire laborers when needed.","PeriodicalId":379508,"journal":{"name":"CLSU International Journal of Science & Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129904155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interviews and surveys were conducted in order to determine their actions before, during, and after the typhoon. The qualitative data were analyzed using content analysis, while the quantitative data underwent statistical analysis of frequency, percentage, and multiple responses. Based on the findings, the municipal government and the three barangay governments were prepared and conducted the proper emergency responses in the case of Typhoon Karen. All the three barangays have their own information drive as its information system and systematic strategies of preparedness during and after the typhoon. This shows how important the role of the state is for any given community. In the disaster preparedness of the communities, results show that the communities have a high degree of self-awareness in terms of the ongoing situation. During disasters, survival mechanisms performed by the community were primarily to protect life, secure the minimal provision of food and other basic needs, and procure the safety of their residence and valuables. In the aftermath of the typhoon, most of the strategies done by the local people were less dependent on external assistance that hastened the process of going back to normal life after flooding had receded. The activities and programs of the LGUs in relation to the mitigation on the occurrence of floods tend to be insufficient to the needs of the majority. Protection of the people and ensuring their safety and survival have always been the role of every state.","PeriodicalId":379508,"journal":{"name":"CLSU International Journal of Science & Technology","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116094710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability of pigeon pea to produce economic yields under moisturedeficient soils makes it as an ideal crop to integrate in the crop-livestock farming for production of high-quality fodder. Four pigeon pea forage-type variety of the International Crop Research Institute for the SemiArid Tropics (ICRISAT), namely: ICPL 87119, ICPL 13092, ICP 7035, and ICPL 20092, were planted to identify the best variety that is suitable under Central Luzon agro-climatic conditions. A total of 240 plants per variety were planted with 0.5 m x 0.75 m planting distance. The experiment plots were laidout using Randomized Complete Block Design with three replications at the Central Luzon State University. The varieties were evaluated by measuring the growth performance, herbage yield, dry matter yield, and disease tolerance. Results showed significant variations in the survival rate of the different varieties. All varieties exhibited less than 85% survival rate. Among the varieties, ICP 7035 produced the highest herbage yield per hectare of 8.9 tons which was 24.71%, 58.42%, and 68.53% higher compared to ICPL 87119, ICPL 20092, and ICPL 13092, respectively.

The link was perceptible only in a few fields of B2B BPM practices. To form a strong link between the two sectors, the coordinated Single Step Demand-Driven Carabao Milk-Pastillas Chain Model was proposed to ally the two sectors through the Five-Fields Synergy System Model of Linkage Management which was placed in-between the sectors on the assumption that the carabao milk market acts on a demand-driven supply chain principle.
