Utilización de micorrizas arbusculares en el cultivo de arroz (Oryza sativa L.), para tolerancia al estrés hídrico, en condiciones de invernadero

VIII. SUMMARY The present research work was carried out in the premises of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at km. 7.5 of the Babahoyo-Montalvo road. The geographic coordinates (UTM) are X:668690 E; Y: 9801098 N. The zone presents a humid tropical climate, with an average temperature of 24 to 26 ° C, relative humidity 88%, annual precipitation of 1262 mm, a height of 8 msnm2 and 990 hours of annual average heliophany. Seeds of rice, variety INIAP 14 were used as seed material. The treatments consisted of different doses of mycorrhizae, such as: 0.5 and 1.0 l / ha; 10 and 20 kg / ha; plus a control treatment without application of the product. The experimental design Randomized with four treatments and 3 repetitions was used, the test of significance used was Tukey at 95% probability. All the necessary agricultural work in rice cultivation was carried out for its normal development as land preparation, sowing, irrigation, fertilization, weed control, phytosanitary control and harvest. To estimate the effects of the treatments, the following data were taken: plant height, number of tillers, number of panicles, length and width of the flag leaf, vigor, length of the panicles, length of the root, fresh biomass of the root, dry biomass of the root, fresh biomass of the aerial part, dry biomass of the aerial part, days of flowering, grains by panicles, sterility of panicle, weight of 1000 grains, yield of grain, economic analysis. Based on the results obtained, it was determined that the application of mycorrhizae had positive effects on the vigor of the rice crop, variety INIAP 14; Therefore, the importance of carrying out new research on the use of mycorrhizas in agriculture is reflected.
