Agregar Etiqueta | Sumario: | SUMMARY The present experimental work was carried out on the grounds of the Experimental Farm "Palmar" of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at Km 12 of the Babahoyo - Montalvo road. As a seed material, the INIAP 15 rice variety was used. The experimental work consisted of 15 treatments with organic amendments based on Ekotron 70 GR in doses of 50 and 100 kg / ha, Naturvigor - G in doses of 50 and 100 Kg / ha and absolute control and chemical fertilization with doses High (125 kg / ha of N + 32 kg / ha of P2O5 + 91 kg / ha of K2O + 28 kg / ha of S), Mean (91 kg / ha of N + 24 kg / ha of P2O5 + 73 kg / ha of K2O + 19 kg / ha of S) and Low (70 kg / ha of N + 14 kg / ha of P2O5 + 52 kg / ha of K2O + 12 kg / ha of S) and 3 replicates. In the present work, the experimental design of Complete Blocks Random was used in factorial arrangement A x B, where the doses of organic amendments were to factor A and the doses of chemical fertilization corresponded to the factor B. To estimate the effects of the treatments, the data of days to flowering and maturation, plant height, panicle length, number of tillers and panicles, number of grains per panicle, weight of one thousand grains, Yield per hectare and economic analysis. From the results obtained it was determined that the application of Naturvigor - G in doses of 100 kg / ha using 70 kg / ha of N + 14 kg / ha of P2O5 + 52 kg / ha of K2O + 12 kg / ha of S was the treatment that flourished and matured in a longer time; the highest plant height and panicle length were observed with the use of Ekotron 70 GR in doses of 50 kg / ha applying 125 kg / ha of N + 32 kg / ha of P2O5 + 91 kg / ha of K2O + 28 kg / ha of S; In relation to nozzles and panicles / m2 the highest average was reported with the use of Ekotron 70 GR in doses of 50 kg / ha applying 91 kg/ha of N + 24 kg/ha of P2O5 + 73 kg/ha of K2O + 19 kg/ha of S; The highest average number of grains per panicle was obtained with the application of Naturvigor - G in doses of 100 kg / ha using 91 kg / ha of N + 24 kg / ha of P2O5 + 73 kg / ha of K2O + 19 kg / Ha of S and Ekotron 70 GR in doses of 100 kg / ha using 70 kg / ha of N + 14 kg / ha of P2O5 + 52 kg / ha of K2O + 12 kg / ha of S; The highest weight of 1000 grains was obtained with the use of Ekotron 70 GR in doses of 50 kg / ha with 70 kg / ha of N + 14 kg / ha of P2O5 + 52 kg / ha of K2O + 12 kg / ha of S And grain yield and economic analysis obtained higher results with the application of Naturvigor - G in doses of 50 kg / ha using 125 kg / ha of N + 32 kg / ha of P2O5 + 91 kg / ha of K2O + 28 kg / Ha of S with 6916,7 kg / ha and $ 1250,26. |
