Determinar el efecto de la fertilización química y orgánica en la produccion agronomica de cuatro variedades de arroz (Oryza sativa l) en el Cantón Mocache.

The Present Work: Research, yes Development During The Rainy Season of the Year 2014, in La Finca“El 8”, LOCATED IN Km. 8 ½ via Quevedo - El Empalme, Mocache Canton province of Los Rios. The general objective was: Organic Fertilizerassess against chemical fertilization in rice para advance the Development Process New Alternatives Nutrition and Specific Objectives Were: determining S. Rice Variety That Responds best to Organic Fertilizer Application Studio - 09 and CC 05 and Fertilizers "Chemist ", " compost " Y " Humus " INIAP -16 Variety is the USE As a Referrer Be By Iniap -16 , F- 21 , SFL , four rice varieties were evaluated the mayor of area planted in the area of the Upper Basin of the Rio Guayas. Comprehensive Design random (DBCA) blocks, with 12 treatments and three replications was handled. The plots were composed of five rows of five meters, the useful area was formed by the three central rows leaving the remaining by quantitative and qualitative effects of edges. Days to flowering and maturity, plant height at harvest, number of tillers and panicles per square meter, panicle length, grains per panicle and number of openings per panicle, weight of 1000: To evaluate the varieties the following variables were considered grain yield (kg. ha-1. In the statistical evaluation found that there were significant differences between the means of varieties and fertilizers. Most precocious flowering and maturation was obtained in the "Iniap-16" range with based nutrition organic and chemical fertilizers; is important to note that this variety also reached the highest plant height of 73 cm and was also observed that reached the highest number of tillers (256) per square meter; panicles about "Compost x CC-05" reached number 206 per square meter, "NPK x CC-05" achieved greater length and number of grains per panicle inferring how good grain yield. The lower sterility of panicle corresponded to " Humus x SFL- 09" with 2 %, which could have a negative impact on grain yield, it should be noted that the percentage of ineffective fertilizer with the lowest average was the " Compost" ; is important to note that the highest grain yield was achieved in the variety " Iniap -16" with 1938 kg ha- 1 outperforms other varieties , this average was achieved with edaphic supply "Chemist " beating manure significantly . For research programs and agricultural development like this, but make revalidation dose for each origin and organic fertilizer use and proven commercial products; in order to determine optimal nutrition for each subscription.
