Cobre e zinco no material percolado e no solo com a aplicação de água residuaria de suinocultura em solo cultivado com soja

O objetivo deste trabalho foi avaliar possiveis efeitos da aplicacao de taxas de agua residuaria de suinocultura (ARS), quanto as concentracoes de cobre e zinco, tanto no solo quanto na agua percolada de lisimetros de drenagem, durante o ciclo da cultura da soja. O experimento foi conduzido em ambiente protegido, onde havia 24 lisimetros de drenagem. Semeou-se soja cultivar CD 202, e foram aplicadas ARS nas seguintes dosagens: 0; 100; 200 e 300 m3 ha-1 no ciclo, combinadas com duas adubacoes na semeadura (com e sem adicao da adubacao recomendada na semeadura), em tres repeticoes por tratamento. Foram feitas seis coletas do material percolado durante o ciclo da cultura e realizadas determinacoes de cobre e zinco. No solo, foram feitas tres coletas em cada parcela experimental, para a determinacao do pH, da materia orgânica, da capacidade de troca cationica, do cobre e do zinco. O delineamento foi em blocos casualizados, num esquema fatorial de 4 x 2. Observou-se que o cobre no solo nao apresentou diferencas significativas com a aplicacao de ARS e adubacao, enquanto as concentracoes de zinco no solo foram influenciadas pelas taxas aplicadas de ARS. As transferencias de cobre e de zinco por percolacao foram pouco expressivas.

Características físicas e fisiológicas na qualidade industrial de cultivares e linhagens de trigo e triticale

The physical, physiological and rheological characteristics of cultivars and lines of wheat CD (COODETEC) 103, 104, 105, 107, 108, 109, 110, 111 and CD 2017 and CDFAPA 2036 lines and triticale (EMBRAPA 53), for quality of flour for bread making were studied. The weight of hectliter (HW), weight of thousand grains (WTG), percentage of germination, total protein and farinography, in a completely randomized experimental design, with four repetitions, except the farinography (with two repetitions) were analyzed. The means obtained were compared by the Scott Knott test at 5%. The cultivars were different regarding the tested parameters. The PH value were compatible for commercialization, but not always the higher PH value corresponded to the greater weight of thousand grains. Only the CD 108 and 111 cultivars may be destine for French bread considering the stability parameter. About the index of tolerance for the mixture, the cultivars and lines were not different, but only the flour of 2017 line would attend the values that were established for French bread-making and fermented cookies. The CD 104, 108 and 11 cultivars and the CD 2017 and CDFAPA 2036 line obtained the ideal index also for fermented cookies. The cultivars which presented better weight of thousand grain gave the best index of tolerance for the mixture. There was no positive relation between total protein and the farinography.

Adaptation of Stylosanthes Campo Grande to soil conditions in the west of Paraná

This study aimed to evaluate the Campo Grande stylosanthes in the soil conditions of the western region of Parana. The experiment was conducted in pots in a greenhouse at the Faculty Assis Gurgacz (FAG), in Cascavel - PR. We used four treatments (T) with contrasting conditions as soil texture (sand and clay) being formed: T1-latosol, T2-1/3 latosol plus 2/3 sand, T3: 1/2 latosol plus 1/2 sand, T4:1/4 latosol plus 3/4 sand. The experiment design was completely randomized; the variables analyzed were dry matter (DM), root length and crude protein (CP). There was significant effect (P
