    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.
