Effect of organic fertilization and seaweed on the yield of sweet corn (zea mays l.), in the Babahoyo area

The objective of this work was to determine the effect of organic fertilization and seaweed on the yield of sweet corn in the Babahoyo area. Super sweet BANDIT F1 sweet corn was used as planting material. The treatments studied were Algae Oil, at a dose of 500 kg/ha; AlgaTec 2.0 L/ha; Algae oil + AlgaTec 400 kg/ha edaphic + 1.0 L/ha foliar; Algae oil + AlgaTec 600 kg/ha edaphic + 1.5 L/ha foliar; Algasoil + AlgaTec 800 kg/ha soil + 2.0 L/ha foliar and the conventional control with 140 kg/ha of N + 80 kg/ha of P + 90 kg/ha of K. The application interval of the products was at 8, 20 and 40 days after sowing. The BCA “Complete Randomized Block” experimental design was used, with 6 treatments and 4 repetitions. For the evaluation and comparison of means, the Tukey test was used at 95% probability. The agricultural tasks required by the crop were carried out, such as soil preparation, sowing, weed control, irrigation, fertilization, phytosanitary control and harvest. The data evaluated were plant height and ear insertion height; days to maturation and ear length; per hectare and economic analysis. Through the results obtained, it was determined that the application of Agasoil and Algatec did reflect effects on fertilization in the sweet corn crop, in the Babahoyo area; Plant height and ear insertion height obtained better averages with the use of 140 kg/ha of N + 80 kg/ha of P + 90 kg/ha of K; The use of foliar AlgaTec at a dose of 2.0 L/ha was the treatment that matured in the shortest time; the average cob length was 0.19 cm; The numbers of grains per plant stood out with the use of Algasoil + AlgaTec at a dose of 800 kg/ha soil + 2.0 L/ha foliar and the highest grain yield and economic analysis was presented with the conventional control of 140 kg/ha of N + 80 kg/ha of P + 90 kg/ha of K with net benefit of $417.02.
