Efectos de Programas de fertilización edáfico-foliar más microorganismos eficientes en el cultivo de sorgo (Sorghum bicolor L.), Cantón Alfredo Baquerizo Moreno

VIII SUMMARY The experimental work was carried out at the “Comargara S.A. “Property of Mr. Marco Pineda, in the Jujan - Guayas canton. the UTM coordinates are 656 666.814 E and 9783501.198 N, with a height of 7 meters above sea level. The area has a tropical climate, with an average annual temperature of 25.5 ° C, annual precipitation 855.1 mm, relative humidity of 81%. the soil is deep with clay texture, drainage and regular fertility. The material that was used for the sowing was p83g19 certified seed, 10 treatments were carried out with three repetitions plus the absolute control, the design that was applied was complete random blocks with 3 repetitions. The treatments studied consisted of the combination of 3 levels of fertilization with N, P, K, Mg and S, + 3 levels of Raizone + 3 levels of Micro-Rhiz. The variables evaluated were plant height, days to flowering, days to maturation, height of insertion of the panicle, diameter and length of the panicle, weight of 100 grains, grains per panicle, grain yield and partial productivity per nutrient. The level of edaphic fertilizers made up of 100-40-70-20-15 (kg / ha) of N, P, K, Mg, S, respectively, showed the plants with the highest height and the physiological maturation in the absolute control was observed at 131 days after sowing. The treatment consisting of 120-60-90-25-20 (kg / ha) of N, P, K, Mg, S, in their order, presented the best results in the variables of panicle length, number of grains per panicle and performance. Given the above, it is recommended to apply soil and foliar fertilizers with a fertilization program: Nitrogen 120 kg / ha - phosphorus 90 kg / ha - potassium 90 kg / ha - magnesium 25 kg / ha - sulfur 20 kg / ha, Raizone 0.5 l / ha + microRhiz 1.0 l / ha.
