Resumo: Visando estabelecer normas para o DRIS e os valores de referência para avaliação do estado nutricional da cultura do algodão, um produto agrícola em franca expansão no território nacional e com significativa contribuição econômica no PIB brasileiro, o presente trabalho estudou lavouras comerciais de municípios do norte do estado de Mato Grosso do Sul e centro-sul do estado de Mato Grosso, utilizando o método da chance matemática e a metodologia do DRIS para dados de monitoramento nutricional. O método da chance matemática, tendo como referência a produtividade de 4500 kg ha-1, retornou , em g kg-1, de 33-45; 2,8-5,3; 15-21; 20-36; 4,0-7,2 e 2,8-8,6 para N, P, K, Ca, Mg e S, e em mg kg-1, de 53-83; 4-12; 110-440; 40-60 e 25-50 para B, Cu, Fe, Mn e Zn. As faixas indicadas, embora similares às existentes, demonstram aperfeiçoamento para obtenção de altas produtividades. O N é o nutriente que pode ter problemas devido a adubação excessiva nas maioria das áreas, seguido do Mn e do K. Os maiores retornos, promovidos pela adubação, poderão ocorrer em função da aplicação de P e B. Com relação ao DRIS, o método proposto por Elwali & Gascho é menos sensível à forma de escolha da relação (r ou F) para o cálculo do IBN, e a relação escolhida para cálculo do DRIS pelo valor r não é recomendável, exceto quando a diferença entre os coeficientes de correlação, entre a relação direta e inversa, for estatisticamente significativa. Pelos métodos de cálculo das funções DRIS foram diagnosticados como prováveis limitações da cultura o Ca e o Mg, que normalmente são fornecidos via calagem, e também o S. / Abstract: The cotton is an agricultural product in development for Brazil and has significant contribution for Brazilian economy. With the objective to establish DRIS norms and references values for nutritional status availability for cotton crop, this study used commercial areas in the north of the Mato Grosso do Sul state and center-south of the Mato Grosso state, applying the mathematical chance method and the DRIS for nutritional analysis data. The mathematical chance method calculated the cotton sufficiency range, in g kg-1, of 33-45; 2,8-5,3; 15-21; 20-36; 4,0-7,2 and 2,8-8,6 for N, P, K, Ca, Mg e S, and in mg kg-1, of 53-83; 4-12; 110-440; 40-60 and 25-50 for B, Cu, Fe, Mn e Zn. The range furnishing values that can not be obtained by conventional research in short time and the range obtained can be used in the Brazilians production systems. However, it is indicated that these values would be adjusted constantly for supplying the system specificity. For DRIS, the results indicated that the choice for nutrient ratio modify the data interpretation, but the nutritional balance index has correlation. The r value isn't recommended. The DRIS indicated limitation provable for Ca, Mg and S, but the Ca and S is furnished normality by liming. / Orientador: William Natale / Coorientador: Euclides Braga Malheiros / Banca: Ondino Cleante Bataglia / Banca: Takashi Muraoka / Banca: José Carlos Barbosa / Banca: Mara Cristina Pessoa da Cruz / Doutor

In the United States, hops (Humulus lupulus L.) are grown mainly in the Pacific Northwest (PNW). For this reason, most cultural information is based on the growing conditions of the PNW. Growing conditions in Virginia differ drastically and present unique disease and production challenges. Three studies were conducted with the intent of increasing hop cultivation knowledge for Virginia growers. For the first study, 13 cultivars of hops grown at the Virginia Tech hop yard were compared for growth, yield, and quality. Mean cone fresh weight per plant ranged from 12.00 g for Mt. Hood to 1002.87 g for Crystal in 2016 and from 97.98 g for Mt. Hood to 900.33 g for Cascade in 2017. In 2016, only Alpharoma, Cascade, Mt. Rainier, and Southern Cross had alpha acid levels, an indicator of cone quality, within the accepted range. In 2017, Alpharoma, Centennial, Mt. Rainier, and Nugget had alpha acid levels within the expected range. Three cultivars (Cascade, Crystal, and Ultra) were above the expected alpha acid range, which indicates more bittering potential for beer brewers. In a nutrient deficiency study, hop plants were grown in hydroponic solutions, and deficiencies were induced for nitrogen (N), phosphorus (P), and potassium (K). After visual deficiency symptoms had been induced, leaf tissue samples were taken and analyzed for nutrient content. Images were taken at each deficiency stage. For N, incipient deficiency symptoms were observed at a mean of 3.18% dry weight in leaf tissue samples. Visual symptoms included a chlorotic appearance, undersized leaves, and red petioles. Incipient symptoms for P were observed at a mean of 0.307% dry weight in leaf tissue samples. Necrotic spots, leaf cupping, and undersized leaves were apparent with this deficiency. Incipient symptoms for K were observed at a mean of 1.21% dry weight in leaf tissue samples. Symptoms included rounded leaf tips, blue veins, and marginal scorch. In the third study, a whole leaf powdery mildew (Podosphaera macularis) assay was developed and tested using five hop cultivars, Alpharoma, Cascade, Comet, Sorachi Ace, and Tahoma. Leaves were inoculated with powdery mildew (PM) using a settling tower. This method was used to rapidly assess the resistance of cultivars. Leaves were successfully inoculated and PM colonies were allowed to grow for two weeks. Images of the PM colony development on inoculated leaves were compared using ImageJ to determine percentage of coverage. Tahoma was the only cultivar found to produce a significantly different mean percent coverage (19.5%) compared with the resistant cultivars Cascade and Comet (<1%). / Master of Science in Life Sciences / Hops (Humulus lupulus) were first grown in the United States in Massachusetts in the early 1600s. Production of this crop eventually spread throughout the Northeastern US. By the mid-1800s, commercial production spread to southern states such as Virginia. Infestation of pests, e.g., hop aphid and diseases such as downy mildew in eastern states, and prohibition on the production of alcohol caused a significant shift in hop production, which favored the Pacific Northwest (PNW). As a result, in Virginia specific knowledge of hop cultivation is now lacking. Three studies were conducted to increase our knowledge of hop cultivation for the region. For the first study, 13 cultivars grown at the Virginia Tech hop yard were compared for growth, yield, and quality. The cultivars Cascade and Alpharoma had alpha acid levels equal to or higher than expected for the 2016 and 2017 seasons. The alpha acid levels are an indicator of the hop quality from the Cascade and Alpharoma cultivars. Cascade was also a top producer of hop cones with a mean fresh weight of 989.67 g and 900.33 g in 2016 and 2017, respectively. In a nutrient deficiency study, plants were grown in Hoagland hydroponic solutions, which contain all essential nutrients needed for plant growth. This was done to provide photographic documentation to assist local growers with deficiency identification. Deficiencies were induced for nitrogen (N), phosphorus (P), and potassium (K) by removing each of the specific nutrient of interest from each treatment solution. After deficiency symptoms were induced, leaf tissue samples were taken and analyzed for nutrient content. Nutrient deficiencies were documented using photographs. For N, visual symptoms included a chlorotic appearance, undersized leaves, and red petioles. Incipient symptoms for P included necrotic spots, leaf cupping, and undersized leaves. For K, leaf cupping, blue green veins, marginal scorch, and rounded leaf tips. Disease resistance of cultivars is important information for growers and can heavily influence hop yard planning. As such, in another study, an assay for powdery mildew (Podosphaera macularis) was developed that allows for rapid low cost testing of hop cultivars. The assay was tested on the following cultivars: Alpharoma, Cascade, Comet, Sorachi Ace, and Tahoma. Leaves were inoculated with powdery mildew (PM) using a settling tower. Powdery mildew colonies were allowed to grow for two weeks and were then analyzed using ImageJ software to determine percent coverage. At the end of the experiment, Tahoma had significantly greater PM coverage compared to the other cultivars, indicating that Tahoma is less resistant to the specific PM strain. / Hops (Humulus lupulus) were first grown in the United States in Massachusetts in the early 1600s.

Tal avaliação torna-se ainda mais importante, quando se trata do tomate de indústria, uma das hortaliças de maior valor econômico no Brasil e que os fertilizantes chegam a representar 18 % do custo de produção. Para tanto, conceitos de interpretação à diagnose do estado nutricional foram desenvolvidos, como o Sistema Integrado de Diagnose e Recomendação (DRIS) e Diagnose da Composição Nutricional (CND), abordagem CND-clr (relação log centralizada) e CND-ilr (relação log isométrica). Com isso, o objetivo da realização do presente trabalho foi obter as normas e a faixa de suficiência, bem como comparar tais metodologias, a partir dos dados de nutrientes (N, P, K, Ca, Mg, S, B, Cu, Fe, Mg e Zn). Quando analisados individualmente, com exceção do método DRIS, os métodos CND-clr e CND-ilr, apresentaram boas performances e com bons parâmetros de calibração dos métodos. Contudo, quando analisados de maneira conjunta, segundo a distância de Mahalanobis e a partição de Cate-Nelson, todos os métodos, incluindo a transformação log neperiano do teor, não apresentaram diferença significativa. / The evaluation of nutritional status through leaf analysis is important, as a complement to soil chemical analysis, for the identification of nutritional imbalance and ancillary fertilizer recommendation. This evaluation becomes even more important when it comes to the tomato industry, one of the vegetables with the highest economic value in Brazil, and that fertilizers represent 18% of the cost of production. For this purpose, concepts of interpretation and diagnosis of nutritional status were developed, such as the Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrient Diagnosis (CND), CND-clr (centralized log ratio) and CND-ilr (isometric log rato) approach. Thus, the goal of the implementation of this work was to obtain standards and sufficiency range and compare these methods, from the nutrient data (N, P, K, Ca, Mg, S, B, Cu, Fe , Mn and Zn). When analyzed individually, with the exception of the DRIS, the CND-clr and CND-ilr methods presented good performances and with good calibration parameters of the methods. However, when analyzed together, according to the Mahalanobis distance and the Cate-Nelson partition, all methods, including log transformation of the content, showed no significant difference. / FAPESP: 2013/24447-4 / FAPESP: 2015/11321-8
