The diagnosis of nutritional state is an important tool to understand the nutritional requirement of plants and the influence of the nutritional balance on the yield. The proposed in this study was to apply the Diagnosis and Recommendation Integrated System (DRIS) to assess the nutritional state of cotton crop through the order of nutrient requirement and nutritional balance. Yield data from plots (average acreage 100 ha) and foliar concentrations of macro and micronutrients of cotton (Gossypium hirsutum r. latifolium) plants were stored in a database. The criterion to define the reference population consisted of plots with above-average yields + 2/3 standard deviation (over 4785 kg•ha −1 seed cotton yield). The DRIS method was efficient to evaluate the nutrition state of cotton. It was feasible to identify the order of plant requirement and nutritional balance. It was feasible to observe that when minor the Nutritional Balance Index (NBI) it's higher the yield. It means that to reach high yield it is necessary to show low NBI. The Sulphur, Boron and Zinc showed the higher frequency as the most required nutrients by plant. The Magnesium and Manganese were the less required by the cotton plant, this means that both of them were limiting the yield by excess in the tissue.

RESUMO -Objetivou-se estudar os efeitos das combinações de nitrogênio com enxofre nas concentrações de nitrogênio e enxofre e na relação de nutrientes nas folhas diagnósticas e nas raízes do capim-braquiária (Brachiaria decumbens Stapf.) em degradação antes das adubações. Foram coletados cilindros com planta + solo em uma pastagem em degradação em área IntroduçãoO suprimento de nutrientes constitui-se importante fator na nutrição da planta forrageira, tendo em vista que a disponibilidade de nutrientes exerce grande influência na nutrição da planta, que se reflete no desenvolvimento vegetal e na recuperação do capim. Nesse contexto, a deficiência de nitrogênio tem sido apontada como uma das principais causas da degradação de pastagens e também existe a necessidade de se atentar para o enxofre, principalmente quando se aplicam doses elevadas de nitrogênio (Silveira et al., 2005).A maior parte das pesquisas com plantas forrageiras enfatiza o desenvolvimento da parte aérea das plantas, deixando as raízes como um componente "escondido" e não abordando a interdependência entre estas partes dos vegetais. No entanto, é sabido que há necessidade de sistema radicular vigoroso, tanto para a produtividade

There is a concern about the growing population and limitation in natural resources which are taking the population to direct its agricultural systems into a more productive and efficient activity, looking to avoid a negative impact on the surrounding environment. The industry energy expended to produce nitrogen (N)-fertilizer is considered an indirect consumption of energy in agriculture, which is higher with an increasing forage yield. Nitrogen is the key nutrient associated with high-yielding production in forage grass and grain crops. The aim of this chapter is to introduce the best management practices (BMPs) for N-fertilizer application in forage grasses to improve N-use efficiency, since the most economical way to feed livestock is forage plants where its potential biomass production is not well explored. The BMPs basically follow three management practices: (1) soil nutrient availability and forage requirement, (2) fertilizer application, and (3) decrease in nutrient losses from soil. In order to take a decision on applying N-fertilizer to accomplish forage grasses production with social, economic, and environmental benefits, the N-fertilizer use in forage grasses is going to follow the "Right rate, Right source, Right place, and Right time (4R) nutrient stewardship." The application of the 4R's nutrients stewardship is directly associated with economic, social, and environmental impact. The capacity of the 4R's implementation worldwide turns into a best guide to improve the striving of better N-use efficiency in forage grass. The 4R's are interrelated; thus, the recommendation of N-fertilizer rates cannot be prescribed without the combination of the 4R's where a whole system to be followed should be considered to decide about N-fertilizer in pasture. Consequently, any decision in one of the 4R's is going to affect the expected N-fertilizer results and dry matter production.
