1. Sensitivity analysis of the AquaCrop model for wheat crop in Campos Gerais region, Paraná
ABSTRACT The use of crop modeling can be useful to understand the interactions between the soil-plant-atmosphere system. The objective of this study was to evaluate sensitivity analysis of the AquaCrop model parameters for wheat crop in the Campos Gerais Region. The varietie tested was TBIO Sinuelo in Castro, Ponta Grossa and Itaberá cities. The analyzed pa

2. Viability of Italian ryegrass (Lolium multiflorum) seeds under application of synthetic auxin herbicides
ABSTRACT Italian ryegrass (Lolium multiflorum) is one of the main weeds in the wheat crop, and the application of synthetic auxin herbicides has the potential to reduce seed viability, therefore, restricting the input into the seed bank. The objective was to evaluate the effects of synthetic auxin herbicides applied at different growth stages on germination,

3. Silicon in wheat crop under water limitation and seed tolerance to water stress during germination
ABSTRACT Water stress during wheat seed germination and seedling establishment for affect the percentage and speed of germination. Silicon (Si) is related to plant tolerance to different types of stress, then the application of this nutrient in the mother plant during seed production could contribute to the improvement of the seed quality and, consequently,

4. Performance of fungicides on the control of fusarium head blight (Triticum aestivum L.) and deoxynivalenol contamination in wheat grains
RESUMO A giberela é considerada uma doença de difícil controle, num cenário de dificuldades no seu controle químico e pela agressividade do patógeno em produzir toxinas. Diante disso, o objetivo do estudo foi verificar se fungicidas de distintos grupos químicos, isolados ou em mistura são eficazes no controle de giberela e na redução da contaminaç

5. Performance of the AquaCrop model for the wheat crop in the subtropical zone in Southern Brazil
Resumo: O objetivo deste trabalho foi calibrar e validar o modelo AquaCrop para a cultura de trigo (Triticum aestivum) na região dos Campos Gerais, no Sul do Brasil. Foram avaliadas cinco cultivares nas safras de 2007 a 2017. Os dados de entrada no AquaCrop - referentes a clima, cultura, solo e manejo do solo -, coletados em campo, foram obtidos do banco de

6. Growth and yield parameters of white oat and wheat as affected by canola residues
ABSTRACT Despite being an important crop option for Brazilian agriculture, canola has some characteristics that may limit its insertion in some cropping systems, such as its allelopathic effects. Thus, the present work aimed to study the effect of canola crop residues on the seed germination, growth and grain yield of white oat and wheat plants. In laborator

7. Agroforestry systems and understory harvest management: the impact on growth and productivity of dual-purpose wheat
Abstract: The objective of the study was to evaluate the growth and production efficiency of forage-grain dual-purpose wheat in two arrangements and four agroforestry systems (Intercrop-I and Intercrop-II), as well as to evaluate crop management for the wheat crops in two planting seasons (Crop Season I-2014 and Crop Season II-2015. The experiment was condu

8. Chemical characterization of wheat kernels naturally contaminated by deoxynivalenol-DON when cultivated under nitrogen management strategies
RESUMO Composição química e contaminação de grãos de trigo (Triticum aestivum L.) afeta diretamente a qualidade da farinha obtida, determinando sua aceitabilidade e uso pela indústria. Ensaios foram conduzidos a campo para avaliar o impacto de práticas agrícolas na qualidade de grãos de trigo (composição química e contaminação). O cultivo foi

9. Malting of preharvest sprouted wheat
RESUMO Germinação pré-colheita é um importante problema da cultura do trigo, sendo necessário encontrar alternativas para uso desses grãos porque eles são rejeitados pelos moinhos. No campo, sob determinadas condições climáticas, os grãos são estimulados a germinar, a atividade metabólica aumenta e as enzimas hidrolíticas alteram proteínas e c

10. Evaluation of bioherbicidal potential of Carica papaya leaves
Resumo Devido ao aumento do número de ervas daninhas resistentes aos herbicidas, é necessário explorar o potencial alelopático das plantas como uma alternativa. A pesquisa foi conduzida com o objetivo de investigar os efeitos alelopáticos do pó foliar de Carica papaya e do extrato aquoso das sementes, bem como das sementes pré-germinadas de Avena fatu

11. Selection gain and interrelations between agronomic traits in wheat F5 genotypes
ABSTRACT This work aimed to estimate the variance components and genetic parameters, the selection gain, and the cause and effect relationships among traits in order to identify important traits for direct and indirect selection of wheat (Triticum aestivum L.) lines. Three strategies were used to obtain selection gains: direct and indirect selection, an inde

12. Phosphorus acquisition by wheat from organic and inorganic sources labelled with 32P and 33P radioisotopes
ABSTRACT: Investment in soil phosphorus (P) capital in the tropics is often constrained by poor availability of mineral fertiliser to small-scale farmers. Consequently, new sustainable agricultural cropping strategies are required to maintain fertility and maximise crop yields. The co-application of Tithonia diversifolia (Tithonia) green manure and mineral f
