The zone presents a humid tropical climate, with an average annual temperature of 25.60 ° C; an annual rainfall of 2329.8 mm; Relative humidity 82% and 998.2 hours of annual average heliophany. The soil has a flat topography, a loamy clay texture and regular drainage. Seed material and Iniap 14 and Iniap 16 rice seed treatments were used as seed material and interacted with 50, 75, 100, 125 and 150 kg / ha of N. The experimental design called "Random Complete Blocks" was used, in factorial arrangement A x B, with ten treatments and three repetitions. Factor A was the rice varieties and Factor B the doses of nitrogen fertilizer. All the evaluated variables were evaluated with the Tukey test. During the development of the crop, the following tasks and agricultural practices were carried out: land preparation, sowing, irrigation, fertilization, weed control, phytosanitary control and harvesting. Based on the results obtained, it was determined that the agronomic behavior of the rice varieties responded favorably to the application of nitrogen fertilization; the agronomic characteristics of plant height, number of tillers and panicles / m2, length of panicles, grains per panicles and weight of 1000 grains stood out in the Iniap 16 variety with 125 kg / ha of N and the highest crop yield and net benefit It achieved better results by planting the Iniap 16 variety with 125 kg / ha of Nitrogen applied at 15.30 and 45 days after the transplant with 5341.0 kg / ha and 268,09.

Caracterización morfológica de pasto King Grass “morado” (Pennisetum purpureum), en las condiciones edafoclimáticas de Babahoyo
Get PDFThis research was carried out with the purpose of morphologically describing the "purple" King Grass (Pennisetum purpureum), under the agro-ecological conditions of the Babahoyo canton. Morphological diversity was analyzed in a sample size of 16 individuals located within the Faculty of Agricultural Sciences of the Technical University of Babahoyo located in Babahoyo province of Los Ríos. To evaluate the variability of phenotypic characteristics of the King Grass pasture, adapters used for other studies of the same nature were adapted. As results, it was possible to show that there are no phenotypic differences in the evaluated ecotypes of "purple" King Grass (Pennisetum purpureum), since none of the variables exceeded a Cv> 50%, indicating that the species has little variability. Regarding the correlation coefficient, the results show a relationship between the evaluated variables, where it was possible to determine that there are variables that are related such as: the weight of the leaf with the height of the plant with a value of 0.63; Likewise, a relationship between leaf width and stem diameter was evidenced with a value of 0.59. On the other hand, the analysis also shows a strong relationship between dry weight and wet weight with a value of 0.92.This research was carried out with the purpose of morphologically describing the "purple" King Grass (Pennisetum purpureum), under the agro-ecological conditions of the Babahoyo canton.

Get PDFPastures and forages are the most widely distributed plants in the world and constitute the main source of food for domestic and wild herbivores that graze in grasslands, with proper management they can provide the necessary nutrients and develop their physiological functions. The problems that normally occur in grasslands are mostly due to the affected use of pastures and the lack of adequate productive parameters such as: altitude, rainfall, nutrients and the use of species with low yield potential, which leads to limited forage production, reducing the amounts of dry matter per square meter of cultivated area. Fertilization in pastures constitutes the factor that specifically affects crop yields; It is possible to use complementary mineral products such as biostimulants or biofertilizers that optimize the physiological functions of plants, contributing significantly to crop yield. This study applied different biostimulants in varied doses, obtaining favorable results in the length of the leaf with the Yoduo biostimulant in a dose of 1L / ha reaching a measure of 28.25 cm, in addition with the same treatment positive results were obtained regarding the Green and dry matter weight. It is concluded that the effect of biostimulants in Pasto de Janeiro has the potential to increase the production and current competitiveness of this crop.Pastures and forages are the most widely distributed plants in the world and constitute the main source of food for domestic and wild herbivores that graze in grasslands, with proper management they can provide the necessary nutrients and develop their physiological functions.

Los problemas que generalmente se presentan en pastizales, se deben en su mayoría al uso inadecuado de las pasturas y la falta de parámetros productivos adecuados como: altitud, precipitaciones, nutrimentos y la utilización de especies de bajo potencial de rendimiento, que conlleva a una limitada producción forrajera, disminuyendo las cantidades de materia seca por metro cuadrado de superficie cultivada. La fertilización en los pastos constituye el factor que incide significativamente en el rendimiento de las cosechas; se la puede realizar empleando productos complementarios minerales como bioestimulantes o biofertilizantes que optimizan las funciones fisiológicas de las plantas, contribuyendo en forma significativa al rendimiento del cultivo. Este estudio se aplicó distintos bioestimulantes en dosis variadas, obteniéndose resultados favorables en la longitud de la hoja con el bioestimulante Yoduo en dosis de 1L/ha alcanzado una medida de 28,25 cm, además con el mismo tratamiento se obtuvieron resultados positivos en cuanto al peso de materia verde y seca.
