The area has a humid tropical climate, with an average annual temperature of 25.60 ° C; an annual rainfall of 1730 mm; relative humidity 82%. The soil is of alluvial origin, flat topography, loamy texture, drainage and regular fertility. Rice seeds SFL-11 and Iniap FL 1480 varieties were used as treatments, interacting with Fertiarroz fertilization programs (240 kg / ha) + Urea (60 kg / ha) + Ammonium sulfate (60 kg / ha) + Potassium muriate (120 kg / ha); Urea (300 kg / ha) + Magnesium Sulfate (60 kg / ha) + Potassium Muriate (60 kg / ha) + DAP (60 kg / ha); 8-20-20 (120 kg / ha) + Nitro Pac Rice 1 (120 kg / ha) + Urea (240 kg / ha); Urea (240 kg / ha) + 8-20-20 (120 kg / ha) + Potassium Muriate (60 kg / ha) + Ammonium sulfate (60 kg / ha) and DAP (180 kg / ha) + Urea ( 240 kg / ha) + K Mag (240 kg / ha). The experimental design called "Random Complete Blocks" was used, in factorial arrangement A x B, with ten treatments and three repetitions, the variables evaluated were tabulated with the Tukey test. During the development of the crop, the following agricultural work and practices of land preparation, planting, irrigation, fertilization, weed control, phytosanitary control and harvesting were carried out. From the results obtained, it was determined that the application of fertilization programs in rice cultivation under irrigation conditions, obtained favorable responses in the Babahoyo area; The agronomic characteristics of plant height, tillers and panicles / m2, panicle length, grains per panicle, weight of 1000 grains and yield stood out with the planting of the INIAP FL 1480 variety with the use of DAP (180 kg / ha) + Urea (240 kg / ha) + K Mag (240 kg / ha) and the greatest net benefit was obtained by planting INIAP FL 1480 using the Urea fertilization program (300 kg / ha) + Magnesium Sulfate (60 kg / ha) + Potassium Muriate (60 kg / ha) + DAP (60 kg / ha) with an economic gain of $ 350,18 |
