Semira 1, between the geographic coordinates 256 947.50 UTM of West longitude and 411 142.54 UTM of South latitude; with a height of 8 m.s.n.m. The area has a humid tropical climate, with an average annual temperature of 25.60 ° C, an annual rainfall of 2329.8 mm; 82% relative humidity and 998.2 hours of annual average heliophany. The soil has a flat topography, loamy-clayey texture and regular drainage. SFL-11 rice seeds were used as planting material. In the trial, treatments such as potassium phosphite in doses of 0.5 and 1.0 L / ha were used; Potassium humate in doses of 0.5 and 1.0 L / ha; Potassium Phosphite + Potassium Humate in doses of 0.5 + 0.5 L / ha and an absolute Witness without product application. The experimental design called "Randomized Complete Blocks" was used, with six treatments and four repetitions. All the variables evaluated were subjected to the analysis of variance and to determine the statistical difference between the means of the treatments, the Tukey statistical significance test was used at the 5% level. During the development of the crop, agricultural work and practices were carried out such as land preparation, planting, irrigation, fertilization, weed control, phytosanitary control and harvest. From the results obtained, it was determined that the application of potassium phosphite and humate positively influenced the cultivation of rice (Oryza sativa L.) in the Baba area; The use of potassium Humate at a dose of 1.0 L / ha was the treatment that obtained the best results in the variables plant height, tillers and panicles per square meter, panicle length, number of grains per panicle and weight of 1000 grains and the highest grain yield with 5336.0 kg / ha and net profit of $ 208.4 was presented with the use of potassium Humate in doses of 1.0 L / ha. |
