ItemAnálisis de la cultura lectora desde un enfoque educativo primario: caso “Escuela Franklin Delano Roosevelt”, Portoviejo, 2019.(Universidad Técnica de Manabí, 2019) Laz Palma, Julexi Cristina ; Navarro Cedeño, Viviana ; " "The objective of the research is to identify the reading level in primary level students in the basic general education system. To develop the situational state of reading, a scientific, descriptive, and statistical methodology is applied; in the first moment it is developed in the structural function of the investigation which are the theoretical references, the second moment is centralized in obtaining data to establish this step the informational contrast is performed applying the qualitative and quantitative techniques that are segmented by the instruments. The third moment where statistics is applied and complemented by field activity, which is to survey students to determine the results using statistical tables. To execute the data collection, a survey is applied to boys and girls who attend the institution, who are in the 4th grade levels. year and 7th. year. These meet ages between 8 and 12 years and the total number of the sample that corresponds to 50 participants. The results that are appreciated in the statistics determined that children have a liking for reading, this is because the teachers who work within the institution contribute significantly to children, in addition to the “Manabí Grows Reading” program that it offers support in the line of connection, secondly that it is of vital importance to strengthen reading and encouragement for reading pleasure; and in conjunction with students from the library, documentation and archive career at the University; on the other hand, the children hold as part of this support that the readers' tastes vary, but they enjoy interpretive reading and that related to characters that manage to be brought in a scenic way.

LATIN AMERICA PRODUCES 35% OF THE LIMES AND LEMONS CONSUMED IN THE WORLD. ITS CULTIVATION COULD BE AFFECTED BY EXOTIC AND NATIVE PHY-TOSANITARY PROBLEMS. THE OBJECTIVE OF THIS RESEARCH WAS TO ANALYZE THE OCCURRENCE AND IMPACT OF DISEASES AND PESTS IN C. AURANTIIFOLIA AND C. LATIFOLIA IN LATIN AMERICA. A REVIEW WAS CARRIED OUT IN DIFFERENT DATABASES, SUCH AS ACADEMIC GOOGLE, FAO AND EPPO. THE MAIN BACTERIAL AND FUNGAL DISEASES REPORTED ARE: CANKER CAUSED BY XANTHOMONAS CITRI SSP. CITRI, AN-THRACNOSE DUE TO COLLETOTRICHUM GLOEOSPORIOIDES AND COLLETOTRICHUM ACUTATUM AND GUMMOSIS ASSOCIATED WITH, PHYTOPHTHORA PARASITICA. AMONG THE VIROSIS, THE LEPROSIS VIRUS AND THE CITRUS TRISTEZA VIRUS, TRANSMITTED BY MITES, BREVIPALPUS SPP. AND TOXOPTERA CITRICIDA, RESPECTIVELY. PHYLLOCNISTIS CITRELLA IS CONSIDERED A PRIMARY PEST THAT BUILDS GALLERIES IN THE LEAVES, DEFORMING THEM AND AFFECTING THEIR DEVELOPMENT. THIRTY ONE TAXA OF COCCOIDEA AND FIVE OF WHITEFLIES (ALEYRODIDAE) WERE REPORTED. HOWEVER, THE MOST RELEVANT PHYTOSANITARY PROBLEM IS HUANGLONGBING (HLB) DE-TECTED IN THE AMERICAS IN BRAZIL IN 2004. IT IS CAUSED BY THE BACTERIA CANDI-DATUS LIBERIBACTER SPP. AND TRANSMITTED BY DIAPHORINA CITRI. THE PRODUCTION OF LIMES AND LEMONS IN LATIN AMERICA HAS FACED CHALLENGES IN DISEASE AND PEST MANAGEMENT. WHILE TECHNOLOGIES ARE GENERATED TO REDUCE THE DAMAGE CAUSED BY HLB AND OTHER PHYTOSANITARY PROBLEMS, CITRUS GROWERS MUST UNDERTAKE STRATEGIES THAT ALLOW THEM TO MANAGE THEM RATIONALLY AND AT THE SAME TIME MAINTAIN PRODUCTION LEVELS.

IN THE SELECTED PLANTS, THE MOISTENING CONE WAS DETERMINED STARTING FROM EACH SELECTED PLANT FROM 0.50 TO 1.50 METERS FROM THE PLANT, FOR WHICH THE TDR 300 VOLUMETRIC HUMIDITY METER WAS USED. THE UNIFORMITY COEFFICIENT OF THE INSTALLED IRRIGATION SYSTEM, FOR WHICH 16 RAIN GAUGES WERE PLACED FOR EACH SAMPLED UNIT. THE COEFFICIENT WAS DETERMINED FROM THE 25% MEAN FLOW RATES AND THE TOTAL MEAN FLOW RATES. WITH THE RESULTS OF THE DETERMINATION OF THE BEHAVIOR OF THE IRRIGATION SYSTEM, THE PROPOSAL OF THE OPERATION PROGRAM OF THE IRRIGATION SYSTEM WAS MADE, FOR WHICH AN AVERAGE FLOW RATE OF THE DRIPPERS OF 1.88 L/H WAS OBTAINED, WITH A UNIFORMITY COEFFICIENT OF 97 %, DEMONSTRATING THAT THE UNIRAM HOSE DRIP IRRIGATION SYSTEM GUARANTEES THE WATER REQUIREMENT OF THE COCOA CROP.
