ItemBACTERIAS SIMBIÓTICAS EN EL CULTIVO DE MANÍ: UNA REVISIÓN(Ingeniero Agronomo, 2022-06)THE OBJECTIVE OF THIS WORK IS TO COLLECT INFORMATION ON THE IMPORTANCE OF SYMBIOTIC BACTERIA IN PEANUT CULTIVATION. PEANUTS ARE OF GREAT ECONOMIC IMPORTANCE, BEING PRESENT WITHIN THE FOUR MOST IMPORTANT GRAINS IN THE WORLD. ITS WIDE DISTRIBUTION RANGES FROM ASIA, AFRICA, AMERICA, AND SOUTH AMERICA. THE ENTIRE BIOLOGICAL PROCESS OF A LEGUME IS CARRIED OUT IN THE ROOT SYSTEM WHERE THE RHIZOBIA THAT ARE PART OF THE ROOT NODULES ARE RESPONSIBLE FOR FIXING NITROGEN INDEPENDENTLY, THIS PROCESS IS RESPONSIBLE FOR TRIGGERING THE GROWTH, DEVELOPMENT, AND PERFORMANCE OF PLANTS. THE SYMBIOTIC BACTERIA PRESENT IN THE SOIL ARE RESPONSIBLE FOR FIXING NITROGEN, AS WELL AS NITRATE AND AMMONIUM, THESE BACTERIA TAKE NITROGEN FROM THE AIR, GIVING RISE TO COMPOUNDS CAPABLE OF BEING INCORPORATED INTO THE COMPOSITION OF LIVING BEINGS AND THE SOIL. RHIZOBACTERIA HAVE ADVANTAGES RELATED TO THE PROMOTION OF PLANT GROWTH, THROUGH THE AERIAL PART AND THE ROOT, INDUCING THE PRODUCTION OF GROWTH-INDUCING HORMONES IN PLANTS AND HELPING TO PROVIDE NUTRIENTS TO THE ROOTS. A DECREASE IN CHEMICAL FERTILIZERS BY SYMBIOTIC BACTERIA OR RHIZOBACTERIA CAN CHANGE PRODUCTION TECHNIQUES IN THE WORLD BECAUSE THEY ARE HIGHLY EFFECTIVE FOR LEGUMES SUCH AS PEANUTS.

ItemEvaluación del desarrollo y rendimiento de tres variedades de lechuga (Lactuca sativa L.) bajo dos sistemas hidropónicos(Ingeniero Agronomo, 2022-06)HYDROPONICS IS AN AGRICULTURAL PRODUCTION TECHNIQUE IN WHICH IT IS GROWN WITHOUT SOIL AND WHERE NUTRIENTS ARE DELIVERED IN A LIQUID SOLUTION. THIS TECHNIQUE OFFERS NEW ADVANTAGES OVER TRADITIONAL CROPS, WHICH REDUCES COSTS BY SAVING OPERATIONS, SPACE AND PROVIDES A BETTER QUALITY OF PRODUCTS WITHOUT WEARING THE SOIL. THE RESEARCH AIMED TO EVALUATE THE DEVELOPMENT AND YIELD OF THREE VARIETIES OF LETTUCE (LACTUCA SATIVA L.) VAR. CRESPA, VAR. CAPTAIN, VAR REGINA 500, UNDER TWO HYDROPONIC SYSTEMS. IN WHICH A COMPLETELY RANDOM EXPERIMENTAL DESIGN (DCA) WITH BIFACTORIAL ARRANGEMENT (3X2) WAS USED, TOTALING 6 TREATMENTS WITH 4 REPETITIONS, THE FACTORS IN STUDY WERE COMPOSED BY FACTOR A CORRESPONDING TO THE VARIETIES CRESPA (V1), REGINA 500 (V2) AND CAPITATA (V3), THE FACTOR B CONSTITUTED BY TECHNIQUE 1 (NFT) NUTRIENT FILM TECHNICAL HYDROPONIC SYSTEM AND TECHNIQUE 2 (DWC) FLOATING ROOT HYDROPONIC SYSTEM.

ItemEfecto de la fertilización química con macronutrientes sobre la producción de dos variedades de frejol caupí (Vigna Unguiculata L.).(Ingeniero Agronomo, 2022-06)THE COWPEA BEAN IS AN IMPORTANT GRAIN LEGUME THAT CAN MAKE A POWERFUL CONTRIBUTION TO IMPROVING DIETARY INTAKE (FOOD SECURITY) IN HUMANS. THE LOSS OF SOIL FERTILITY CAUSED BY OVEREXPLOITATION AND INADEQUATE SOIL MANAGEMENT IS A PROBLEM THAT AFFECTS THE HUMAN BEING, FOR WHICH ALTERNATIVES MUST BE DEVELOPED TO IMPROVE SOIL FERTILITY IN ORDER TO OBTAIN GOOD PRODUCTION. THE PRESENT EXPERIMENTAL RESEARCH WORK WAS CARRIED OUT IN LODANA, SANTA ANA, MANABÍ, ITS OBJECTIVE WAS TO EVALUATE THE EFFECT OF THE DOSES OF CHEMICAL FERTILIZATION WITH MACRONUTRIENTS ON THE PRODUCTION OF THE INIAP 465 AND INIAP 463 VARIETIES OF COWPEA BEANS, THE TREATMENTS WERE DOSAGES NITROGEN, PHOSPHORUS, POTASSIUM AND SULPHUR. PLANT LENGTH, STEM DIAMETER, DRY MATTER OF BEAN ORGANS, NUMBER OF SEEDS PER PLANT, NUMBER OF GRAINS PER SEED, YIELD KG/HA AND AGRONOMIC EFFICIENCY OF NUTRIENTS WERE EVALUATED. THE RESULTS SHOWED THAT THE FERTILIZATION DOSE WITH 37-3.2-31-9 KG/HA OF N, P, K AND S, RESPECTIVELY, INFLUENCED THE DEVELOPMENT VARIABLES

Item“Efecto de densidades poblacionales del fréjol (Vigna unguiculata L. Walp) variedad INIAP-463 con dos fertilizantes inorgánicos”(Ingeniero Agronomo, 2022-06)IN THE PRESENT RESEARCH WORK, THREE POPULATION DENSITIES AND TWO TYPES OF SYNTHETIC FERTILIZERS NOVATEC (N15, P3, K20) AND YARAMILA (N12, P9, K18) WERE EVALUATED, IN ORDER TO DEMONSTRATE WHICH DENSITY AND FERTILIZER GIVE THE HIGHEST YIELD IN THE VARIETY. OF BEANS INIAP-463. THE OBJECTIVE OF THE RESEARCH WAS TO "EVALUATE THE EFFECT OF POPULATION DENSITIES OF BEANS (VIGNA UNGUICULATA L. WALP) VARIETY INIAP-463, WITH TWO INORGANIC FERTILIZERS IN THE MACONTA COMMUNITY OF THE COLÓN PARISH." A COMPLETELY RANDOMIZED BLOCK DESIGN (DBCA) (3X2+3) WITH 3 REPLICATIONS AND NINE TREATMENTS IN A TOTAL AREA OF 450 M2 WAS USED. THE DENSITIES AND PLANTING DISTANCE WERE: D1, 1M X 0.60 M = 33.333PL/HA; D2, 1M X 0.50M = 40,000 PLANTS/HA; D3, 1M X 0.40M = 50,000 PLANTS/HA. THE VARIABLES EVALUATED WERE GERMINATION PERCENTAGE (%), GUIDE LENGTH (CM), STEM DIAMETER (MM), CHLOROPHYLL INDEX (SPAD UNITS), POD LENGTH, NUMBER OF PODS, DRY GRAIN YIELD IN KG/HA, HUNDRED SEED WEIGHTS TO GRAMS AND AGRONOMIC NUTRIENT EFFICIENCY (AE).

Item“HONGOS QUE CAUSAN NECROSIS APICAL Y MUERTE DE RAMAS EN LIMÓN SUTIL (Citrus x aurantifolia Christm. Swingle) EN LA PROVINCIA DE MANABÍ”.(Ingeniero Agronomo, 2022-05)CITRUS FRUITS BELONG TO THE RUTACEAE FAMILY AND HAVE BEEN MENTIONED SINCE ANCIENT TIMES (BETWEEN 776 & 600 BC), THEY ARE MAINLY CULTIVATED FOR THEIR NUTRITIONAL AND ECONOMIC VALUE. THE SANTA ANA CANTON AND ITS SURROUNDINGS ARE CONSIDERED AMONG THE MAIN PRODUCING AREAS OF LEMON IN MANABÍ, PLACES IN WHICH SEVERAL PHYTOSANITARY PROBLEMS CAN BE OBSERVED. HOWEVER, SYMPTOMS OF APICAL NECROSIS AND REGRESSIVE DEATH IN LEMON BRANCHES IS ONE OF THE MOST COMMON PROBLEMS OBSERVED IN THE VAST MAJORITY OF FARMS. DUE TO THE AFOREMENTIONED, IN THE PRESENT WORK THE OBJECTIVE WAS TO IDENTIFY UP TO THE GENDER LEVEL THE CAUSAL AGENT OF SAID DISEASE. FOR WHICH, SAMPLES WERE COLLECTED IN 7 FARMS FROM VARIOUS SECTORS AYACUCHO, LA POZA, PEMINCHE, ESTERO SECO, EL BELDACO AND RIO CHICO, THESE WERE TAKEN TO THE PHYTOPATHOLOGY LABORATORY OF THE EXPERIMENTAL STATION OF THE INIAP HEADQUARTERS PORTOVIEJO LOCATED IN THE PARISH OF COLÓN WHERE THE RESPECTIVE ISOLATIONS WERE MADE.
