Fertilization synthetic and organic and effect on the production of maize variety yield Nutrinta

Abstract

In Nicaragua, the corn (Zea mays L) production occupies an important place in the economy, being considered the product of greater human consumption and main source of calories. This study pretends to generate necessary information about the fertilization formulas (Nitro xtend and Fertimaíz) responding to the farmer problems of their low maize yields. The research was conducted in the center of experimentation and validation of technology (CEVAT), Las Mercedes located at km 11 Carretera Norte, Managua Nicaragua with geographic coordinates from 12° 10’14” to 12°08’05” North latitude and 86°10’22” to 86°09’44” West longitude, at 56 meters above see level, carried out during the months of October 2015 to January 2016. The soils in this area are derived from volcanic ash, young soils and it belongs to the Las Mercedes Serie of clay loam texture. The aim was to compare the effect of different sources of synthetic and organic fertilizers on the growth and yield of maize, the first with traditional fertilizer (12-30-10 and urea), the second with special fertilizers (fertimaiz and nitro xtend) and organic (humus). The total area of the assay was 410.8 m2 and data were analyzed with the INFOSTAT satatistical program. The the results show that there were significant differences in the variables: stalk diameter (2.15 cm), height of insertion of the tassel (225.08 cm), the traditional treatment showed the best results, with plant height (215.43 m), number of leaves (8.58), leaf area (604.06 cm2). But, Tassel insertion (129.77 cm) and yield (3 453.48 kg ha-1 were better with the treatment of Fertimaiz y Nitro Xtend.
