    Desarrollo fenológico del cultivo del fréjol (Phaseolus vulgaris L.) Var. Cargabello en el cantón Bucay provincia del Guayas
    (2017) Villalba Yánez, Juan David; Gutiérrez A., Alberto
    The research work was carried out with the aim of contributing and generating data on the bean (Phaseolus vulgaris L.) crop cycle to plan the commercialization and volumes of water to be applied at each phenological stage, to be disseminated to farmers and For educational purposes. According to the GPS Global Positioning System, it is at a height of 352 meters above sea level, and in geographical coordinates of 2º 12 '15 "south latitude and 79 ° 07'33" west longitude. Statistical analysis was applied with means of central tendency (Means, Standard deviation), where the following results were obtained, for the plant height variable in the final stage of the culture the average was 48.9 cm, for the root depth variable in The same stage presented an average of 32 cm, relating height and radical depth is 2/3 of the aerial part with the depth of the root. In the variable days at harvest, the time elapsed from sowing to dry harvesting was 102 this is due to climatic conditions that arose in the experiment especially in relation to high relative humidity. In the variable coefficient of the bean crop, the values given by FAO56 were taken, where the coefficient of cultivation (Kc) for the initial stage is 0.4 with a duration of 23 days. At the development stage the crop coefficient increases gradually, After 30 days reaches its maximum coefficient of crop (Kc) of 1.15 that presented in the intermediate stage since at this stage the consumptive use of the plant reaches its highest point the value of Kc remains constant for 28 days, In the final stage the Kc descends until reaching 0.35 with a duration of 21 days. Phenological stages of bean cultivation in the climatic conditions of Bucay, Guayas province had these durations for the initial stage 23 days, for the stage of development 30 days, for the intermediate stage or mid season the duration was 28 days and For the final stage or maturation 21 days, which allows us to know when the crop needs more or less water and fertilizers in addition can be scheduled the moment the product is ready to be marketed KEYWORDS: Phenological stages, bean, cultivation coefficient, root depth, plant height, Bucay.

    Etapas fenológicas del cultivo del pimiento (Capsicum annuum. L) VAR. Verde, bajo las condiciones climáticas del cantón general Antonio Elizalde (Bucay) provincia del Guayas
    (2017) Buñay Vallejo, Cristhian Jhon; Gutiérrez A., Alberto
    The research work was carried out with the aim of determining the cycle of cultivation of pepper var. Verde, in the climatic conditions of General Antonio Elizalde (Bucay), province of Guayas, the research work was carried out on the estate of Mr. Olmedo Buñay in the general Antonio Elizalde (Bucay), Guayas province, located in the Sector of the Bucay road - Enclosure. Lemon River. The geographical coordinates are: 2 ° 20 'South latitude and 79 ° 15' West longitude with an altitude of 320 meters above sea level. Statistical analyzes were applied with means of central tendency (Medias, Standard deviation), where the following results were obtained for the variable plant height in the intermediate stage of the crop presented an average of 30.9 cm, for the variable depth in the Intermediate stage presented an average of 27.2 cm, data that when relating them one obtains 1 to 1 of the aerial part with the depth of the root. For the variable coefficient of the pepper crop, the values given by FAO56 were taken where the coefficient of cultivation (Kc) for the initial stage is 0.6 with a duration of 25 days, at the development stage the crop coefficient increases, then Of 45 days reaches its maximum crop coefficient (Kc) of 1.15 that presented in the intermediate stage, in this stage the consumptive use of the plant reaches its highest point the value of the crop coefficient (Kc) remains constant for 38 Days here the crop reaches its commercial maturity. In the variable days at harvest the days from sowing to harvest were 108 this is due to the climatic conditions under which the work was carried out during the period of the research work. The phenological stages of the pepper crop in the climatic conditions of the general canton Antonio Elizalde, province of Guayas had for the initial stage a duration of 25 days, for the development stage a duration of 45 days and for the intermediate or mid season season The duration was 38 days which allows us to know the time when the crop needs more or less water and fertilizers additionally that with this we know the time when the product is ready and in this way allows us to satisfy the demand of the local market . KEYWORDS: Phenological stages, pepper, crop coefficient, root depth, plant height.

    Etapas fenológicas del maíz (Zea mays L.) VAR. Tusilla bajo las condiciones climáticas del cantón Cumandá, provincia de Chimborazo
    (2017) Guzmán Buñay, Dennys Alexander; Gutiérrez A., Alberto
    The research work was carried out with the aim of contributing and generating data on the maize (Zea mays L) cultivation cycle, var. Tusillla to program the commercialization and the volumes of water to be applied in each phenological stage, to be divulged to the producers and for educational purposes the experimentation was carried out in the Canton Cumandá, province of Chimborazo, in the sector known as "La Victoria" in The Rosero estate located on the Bucay-Riobamba road with geographical coordinates: Latitude: S 2 ° 20 'and Longitude: W 79 ° 15' at an altitude of 312 meters above sea level. Statistical analysis was applied with means of central tendency (Means, Standard deviation), the results were as follows, for the plant height variable in the final stage of the culture the average was 285.2 cm, for the root depth variable in the Same stage presented an average of 38.9 cm, relating height and radical depth we have 1/5 of the aerial part with the radical depth. In the variable days at harvest, the time from planting to dry harvest was 141 days. This is due to the climatic conditions presented in the experiment especially in relation to the high relative humidity. In the variable coefficient of the maize crop, the values given by FAO56 were taken where the coefficient of cultivation (Kc) for the initial stage is 0.7 with a duration of 21 days, at the development stage the crop coefficient increases, up to To reach its maximum crop coefficient (Kc), which is 1.20, this occurs after 44 days, in the intermediate stage the consumptive use of the plant reaches its highest point the value of Kc 1.20 remains constant for 42 days, in the Final stage the Kc descends until reaching 0.60 with a duration of 34 days. The phenological stages of maize cultivation in the climatic conditions of Cumandá, had these durations for the initial stage 21 days, for the stage of development 44 days, for the intermediate stage or mid season the duration was 42 days and For the final stage or maturing 34 days, which allows us to know when the crop needs more or less water and fertilizers in addition can be scheduled the moment the product is ready to be marketed
