Comportamiento agronómico de dos variedades mejoradas de pasto mombasa (panicum maximun) y toledo (brachiaria brizantha), sometidos a cuatro niveles de fertilización

VIII. SUMMARY This research was conducted at the Experimental Farm "San Pablo" of the Faculty of Agricultural Sciences at the Technical University of Babahoyo, located at Km 7 ½ of the way Babahoyo - Montalvo. The land is located at the geographic coordinates of 79 ° 32 'South Latitude and Latitude 1 49' West, with a height of 8 meters, it has a humid tropical climate with average annual temperature of 25.5 ° C, average annual rainfall of 2329.00 mm, relative humidity of 82% and 987.1 hours heliophany annual average. The floor is flat topography, clay loam and regulate drainage. Genetic materials used are those obtained from commercial firms with recognized trajectory. Subtratamientos treatments and were composed of grass varieties (Mombasa and Toledo), you interaccionadas levels of fertilization (40-20-20; 60-30-40; 80-40-60; 100-50-80 of N, P K. the design was split plot with two treatments, four subtratamientos and three repetitions. Tukey's test was used to 95% chance for comparison and adjustment of treatment means,. all tasks that require cultivation for normal development, such as soil analysis, soil preparation, planting, watering, weeding, fertilizing, pest and disease control and harvesting were performed. The data evaluated were plant height at 90 days, number of leaves / stems, leaf width at 90 days, diameter entrenudo the lower middle third 90 days, length of the blade at 120 days, stem weight at 90 days, days to flowering, green and dry weight per hectare and economic analysis subject. By the above results it was determined that the variety of grass Mombasa responded favorably to agronomic performance in the area of Babahoyo; as plant height, leaf width, diameter of internode, length of leaves was reported with the variety of grass Mombasa; grass varieties bloomed to an average of 92 days and the greater weight of green and dry matter was reported to the application of 80-40-60 of N, P, K, however the greatest net benefit was observed with the seeding Mombasa grass 40-20-20 applying N, P, K with $ 428.35
