    ´´ ABSORCIÓN DE NUTRIENTES (NPK) EN EL CULTIVO DE ARROZ (Oryza sativa L.) VARIEDAD INIAP 14´´
    (INGENIERIA AGRONOMICA, 2018-09) LOOR BRAVO, CARLOS JOEL
    THE RICE (ORYZA SATIVA L), IS CONSIDERED ONE OF THE MOST IMPORTANT CROPS WORLDWIDE DUE TO ITS GREAT NUTRITIONAL CONTRIBUTION. THIS SOCIAL AND PRODUCTIVE FIELD IS ALSO THE MAIN SUSTENANCE OF THE MANY FARMERS. THE PRESENT INVESTIGATION WAS CARRIED OUT IN THE HORCÓN SITE OF THE ROCAFUERTE CANTÓN, OF THE MANABÍ PROVINCE. THE OBJECTIVE WAS TO EVALUATE THE ABSORPTION OF NUTRIENTS (NPK) IN THE INIAP 14 VARIETY RICE CROP. A RANDOMIZED COMPLETE BLOCK DESIGN WITH FOUR TREATMENTS AND THREE REPLICATES WAS USED. THE TREATMENTS WERE ELABORATED BY APPLYING FOUR LEVELS OF NPK (0-0-0, 50-20-75, 100-40-150, 150-60-225). THE RESULTS SHOWED THAT NUTRIENT THE EXTRACTION (NPK), IN THE FIRST 25 DAYS AFTER TRANSPLANTATION, THERE WAS NOT STATISTICAL DIFFERENCE BETWEEN THE TREATMENTS, THE EFFECT WAS EVIDENT AFTER 50 DDT, WITH THE HIGHEST EXTRACTION OF NITROGEN AND POTASSIUM IN THE TREATMENT WITH THE HIGHEST APPLIED DOSE (T3), WHILE PHOSPHORUS OCCURRED IN T2.

    ANÁLISIS DE LOS PROBLEMAS CAUSADOS POR ARTRÓPODOS PLAGAS Y ENFERMEDADES VIRALES EN CULTIVO DE PIMIENTO (CAPSICUM ANNUUM L.) EN ECUADOR
    (INGENIERIA AGRONOMICA, 2021-10) ÁLVAREZ MOREIRA, LILIANA DENISSE ; CEDEÑO MANZABA, PRISCILA ALEJANDRA
    THE PEPPER (CAPSICUM ANNUUM L.), IS A VEGETABLE CONSUMED WORLDWIDE THAT IN RECENT YEARS PRODUCTION HAS INCREASED CONSIDERABLY IN ECUADOR, BOTH IN THE COASTAL AND ANDEAN REGIONS. LIKE OTHER CROPS, THE PEPPER IS AFFECTED BY INSECTS SUCH AS THRIPS (FRANKLINIELLA OCCIDENTALIS AND THRIPS TABACI), APHIDS (APHIS GOSSYPII AND MYZUS PERSICAE), WHITEFLIES (BEMISIA TABACI) AND MITES (TETRANYCHUS URTICAE AND POLYPHAGOTARSONEMUS LATUS), WHICH WOULD AFFECT YOUR PERFORMANCE. ALSO, THIS CROP IS AFFECTED BY VIRUSES. A BIBLIOGRAPHIC REVIEW WAS CARRIED OUT IN ORDER TO DETERMINE THE MAIN PESTS, NATURAL ENEMIES AND VIRUSES THAT AFFECT PEPPERS IN ECUADOR. THE RESULTS SHOWED THE REPORT OF SEVEN SPECIES OF ARTHROPOD PESTS, AND 16 TAXA OF NATURAL ENEMIES. REGARDING THE VIROSIS, SIX SPECIES OF VIRUS WERE FOUND. ALTHOUGH THERE ARE SEVERAL ALTERNATIVES FOR PEST MANAGEMENT, IN THE COUNTRY FARMERS PREFER TO USE MAINLY CHEMICAL CONTROL. THIS INFORMATION SERVES AS THE BASIS FOR THE KNOWLEDGE OF THE ASSOCIATED ARTHROPODOFAUNA, AS WELL AS OF THE EXISTING VIRUSES AS A BASIS FOR DESIGNING MORE RATIONAL MANAGEMENT STRATEGIES FOR EXISTING PROBLEMS.

    (INGENIERIA AGRONOMICA, 2021-03) Castro Posligua, Genessis Josselyn ; Cevallos Cedeño, Héctor Onides
    THE PEANUT CROP IS BETWEEN LEGUMES ONE OF THE MOST IMPORTANT FOOD CROPS IN THE FIELD AND HEALTH BENEFITS IN PROVIDING NUTRITIONAL COMPONENTS. IN ADDITION, IT IS CHARACTERIZED BY BEING GROWN IN AREAS THAT ARE CONSTANTLY HIT BY PERIODS OF DROUGHT AND ADVERSE CONDITIONS THAT HARM DEVELOPMENT AND PRODUCTION. RESEARCH WAS DEVELOPED WITH THE OBJECTIVE OF EVALUATING THE PHYSIOLOGICAL, BIOCHEMICAL AND PRODUCTIVE TWO PEANUT VARIETIES UNDER WATER DEFICIT. THE EXPERIMENT WAS CONDUCTED EVALUATING VARIETIES OF PEANUT CANDY AND ROSITA 380, WHICH UNDERWENT FOUR PERIODS OF DROUGHT. PHYSIOLOGICAL, MORPHOLOGICAL, BIOCHEMICAL AND PRODUCTIVE VARIABLES WERE EVALUATED SUCH AS STOMATAL CONDUCTANCE, WATER POTENTIAL, CHLOROPHYLL INDEX, NUMBER OF NODULES AND PODS, DRY WEIGHT OF THE PLANTS AND GRAIN PRODUCTION, IN ADDITION TO THE CONTENT OF PROTEINS, FAT, SATURATED AND UNSATURATED FATTY ACIDS.

    LA CADENA DE PRODUCCIÓN DEL CACAO EN ECUADOR: RESILIENCIA EN LOS DIFERENTES ACTORES DE LA PRODUCCIÓN
    (INGENIERIA AGRONOMICA, 2021-07) GARCIA BRIONES, ANA ROSA ; PICO PICO, BRYAN FERNANDO
    CACAO IS ONE OF THE TRADITIONAL ECUADORIAN EXPORT PRODUCTS AND IN THE LAST THREE YEARS ECUADOR HAS BEEN THE THIRD LARGEST PRODUCER IN THE WORLD. SEVERAL FACTORS SUCH AS CLIMATE CHANGE, HIGH CONCENTRATIONS OF CADMIUM (CD) AND THE GLOBAL PANDEMIC OF COVID-19 ARE INFLUENCING THE ECUADORIAN COCOA PRODUCTION CHAIN. BASED ON AN ANALYSIS OF THE CHARACTERISTICS OF THE PRODUCTION AND MARKETING CHAIN OF COCOA IN ECUADOR, THE CHARACTERISTICS OF THE TYPES OF COCOA, THE TYPES OF PRODUCERS, IT IS SHOWN THAT THIS COUNTRY HAS GREAT POTENTIAL TO MAINTAIN PRODUCTION STANDARDS. ALTHOUGH SOME PREVIOUS PLANS HAVE BEEN PROPOSED FOR THE COMPETITIVE IMPROVEMENT OF ECUADORIAN COCOA, BASED ON THE PRODUCTION CHAIN, THESE PLANS HAVE NOT ANALYZED THE FARMER'S PRODUCTION ENVIRONMENT. IN THIS WORK, FIVE LINES OF ACTION BASED ON: IMPROVING THE RURAL ENVIRONMENT OF THE FARMER, PROMOTING ASSOCIATIVITY AND COOPERATIVISM, IMPROVING PRODUCTIVITY AND CONSUMPTION IN THE NATIONAL MARKET, CONSOLIDATING THE INTERNATIONAL MARKET AND RESEARCH ARE PROPOSED AS LINES OF ACTION. IT IS IMPERATIVE TO ENGAGE THESE AXES IN AN ACTION AIMED AT PROVIDING GREATER RESILIENCE IN THE ECUADORIAN COCOA PRODUCTION CHAIN

    COMPORTAMIENTO FISIOLOGÍCO DEL LIMÓN SUTIL (Citrus aurantifolia Swingle) EN SUELOS SALINOS
    (INGENIERIA AGRONOMICA, 2021-08) FERRIN FERRIN, FERNANDO ANDRES
    THE SOILS THAT ARE AFFECTED BY SALINITY HAVE A HIGH CONCENTRATION OF MORE SOLUBLE SALTS THAN CALCIUM CARBONATE AND GYPSUM WHICH DIRECTLY THE GROWTH OF PLANTS. IT IS IMPORTANT TO CONSIDER THAT CITRUS FRUITS ARE PERENNIAL CROPS WITH A WIDE PRODUCTION RANGE AND ARE OF WORLDWIDE IMPORTANCE. SALINITY GENERATES VARIOUS DAMAGES AMONG WHICH WE HAVE: TISSUE BURNS, DECREASED YIELD, FOLIAR ABSCISSION AND PLANT DEATH. SALT STRESS IS ASSOCIATED WITH: A) AN IONIC COMPONENT LINKED TO THE ACCUMULATION TO TOXIC LEVELS OF CL- AND NA + IONS IN THE CYTOPLASM, CAUSING AN IONIC IMBALANCE; B) AN OSMOTIC COMPONENT DUE TO THE COMPARTMENTALISATION OF THIS TOXIC ION IN THE VACUOLE THAT CAUSES THE WATER POTENTIAL OF THE CYTOSOL TO DECREASE TO BALANCE THE LOW EXTERNAL WATER POTENTIAL AND ENSURE THE ENTRY OF WATER INTO THE PLANT CELL AND THUS AVOID DAMAGE TO THE PLANT CELL. MACROMOLECULE. THE CITRUS PRODUCTION IN ECUADOR IS IMPORTANT THE LEMON, CULTIVATED IN THE PROVINCE OF MANABÍ. GIVEN THE IMPORTANCE OF CULTIVATION IN THE PROVINCE, THIS REVIEW FOCUSES ON ANALYZING THE EFFECTS OF SALINE STRESS AND ITS CAUSES, SPECIFICALLY IN CITRUS FRUITS, FOR WHICH A METICULOUS SEARCH FOR INFORMATION FROM STUDIES REGARDING SALINITY WILL BE CARRIED OUT.
