The objective of this study was to evaluate the incidence and influence of stalk rot and ear in cultivation of hybrid corn second crop in west region Paraná. The experiment was conducted in randomized block design with six transgenic corn hybrids (DKB 330PRO, P4285HX, P3646HX, 30F53HX, P3340HX and P3161HX) with four replications at spacing of 0.90 m between rows and 0.20 m between plants. The characteristics evaluated were: number of healthy and symptomatic plants, number of ears healthy and symptomatic and total number of spikes. After harvest, we assessed the length of ears healthy and symptomatic, bulk grain ears healthy and symptomatic, thousand grain weight of ears healthy and symptomatic, and grain mass per spike weighted, thousand grain weight and weighted productivity. The hybrid P3646HX showed 100% of plants with stem base rot (Colletotrichum graminicola) and soft rot cob (Erwi...

This study analyzes the psychometric structure of the CAPE- R scale, which assesses the beliefs about the educational process in rural teachers; explores the teacher´s profile, and analyzes the significant differences between the beliefs according to sociodemographic variables. The sample included 150 rural teachers from Mendoza, Argentina. The exploratory factor analysis yielded a factorial structure made up of four factors that explained a 44.19% of the variance of responses to the test. Internal consistency coefficients ranged from .74 to .85. The data show a predominance of difficulties in the educational process dimension (M=2.83; DE=.69), the only dimension that reached a significant association with the educational level of the classes (F =4.77, p<.05).
