“…In modern agriculture, a common technique to meet the nutritional requirements of plants is fertigation, where nutrients are solubilized and applied via irrigation water. Nonetheless, the success of this practice is related, among other factors, to the irrigation management adopted, knowledge on soil chemical conditions, crop nutritional requirements, application frequency, concentration of the solution to be injected and time of application [25].…”

This study aimed to evaluate the dry matter production and nutrient accumulation of coriander (Coriandrum sativum L.) under pulse and continuous fertigation depths. The experiment was conducted in randomized blocks in 2 x 5 factorial arrangement, with three replicates. Treatments consisted of two types of fertigation application (pulse and continuous) and five fertigation depths (40, 60, 80, 100 and 120% of crop evapotranspiration – ETc). Highest accumulations of dry matter, N, P, K, Fe, Mn, Cu and Zn were obtained with pulse fertigation. Pulse fertigation combined with depths lower than 100% ETc led to highest accumulations of K, Mn, Cu and Zn. The accumulation of nutrients decreased in the following order: K > N > Ca > P > Mg > S > Fe > Mn > Zn > Cu.

“…It allows identifying and correcting deficiencies and nutritional imbalances in plants, and it monitors and evaluates the efficiency of a particular crop fertilization and soil fertility program (Deus et al, 2012). In this sense, the proper use of the results obtained from leaf analyses contribute to a rational use of inputs, promoting the nutritional balance of plants, providing greater crop yield and increasing safety in the use of fertilizers (Souza et al, 2011;Santos et al, 2013).…”

Leaf analysis is one of the main methods used for the evaluation of nutritional requirements in sugarcane culture, contributing to a better management of fertilizers. This study aimed to evaluate the nutritional status of sugarcane varieties by quantifying the leaf content of macro and micronutrients of the +3 leaf. The varieties RB92579, RB867515, VAT90-212 and SP813250 were evaluated in a Yellow Oxisol at Fazenda Jequiá, Anadia, Alagoas (AL) state, during plant-cane, first and second regrowth cycles. The design was randomized blocks consisting of four varieties and five replications. Varietal differences were observed in leaf contents of macro and micronutrients. However, no variety had a higher leaf content regarding any element.

“…Os valores de Al e H+Al foram semelhantes aos encontrados por Souza et al (2011), onde concluíram que o aumento da produtividade do feijão estava correlacionado com a redução dos teores de alumínio. Isso ocorre devido a H+Al e o Al estarem ocupando as cargas do solo que poderiam estar sendo ocupadas por bases, criando uma condição de elevada acidez do solo, no qual segundo Silva et al (2004), reduz o diâmetro radicular à custa do crescimento em comprimento, afetando assim, de forma indireta um ou mais atributos de planta, sendo M100, PG, ALT, e INS.…”

O uso da irrigação por pivô central favorece o cultivo do feijoeiro de terceira safra, contudo, limitações à produtividade são observadas quando cultivados em sistema de semeadura direta, sendo a compactação superficial, incidência de nematoides e variabilidade espacial vertical e horizontal dos nutrientes do solo os principais fatores limitantes deste sistema. O objetivo do estudo foi avaliar o desempenho de cultivares de feijoeiro irrigado em terceira safra, cultivados em sistema de semeadura direta e sua correlação com a fertilidade do solo e incidência de nematoides na região de ecótono Cerrado-Amazônia. O experimento foi desenvolvido no município de Sorriso-MT em um Latossolo Vermelho-Amarelo Distrófico. Os tratamentos foram constituídos por quatro cultivares de feijão, sendo eles: BRS Estilo, BRS Notável, BRS Ametista e BRS Pérola, em uma área total de 9900 m2, onde se determinou através de 83 pontos amostrais georreferenciados os atributos de planta e atributos químicos do solo. Os procedimentos estatísticos utilizados foram: análise descritiva dos dados, análise geoestatística e comparação de médias pelo método “bootstrap”. A maioria dos atributos apresentaram moderada à alta dependência espacial, com elevada variabilidade espacial. O aumento dos teores de potássio gerou incrementos na produtividade, enquanto que o aumento da incidência de nematoides, acidez potencial e saturação de alumínio no solo resultaram em redução. A maior produtividade observada foi da cultivar BRS Pérola, indicando boa aptidão para cultivo nesta região.Palavras-chave: Phaseolus vulgaris L., fertilidade do solo, nematóide, geoestatística. PERFORMANCE OF IRRIGATED BEAN CULTIVARS IN THE CERRADO-AMAZONIAN ECOTONE ABSTRACT: The use of central pivot irrigation favors third-crop bean cultivation, however, productivity limitations are observed when cultivated in a no-tillage system, with surface compaction, nematode incidence and vertical and horizontal spatial variability of soil nutrients, main limiting factors of this system. The objective of this study was evaluate the performance of third-crop irrigated bean cultivars grown under no-tillage system and the correlation with soil fertility and nematode incidence in the Cerrado-Amazonian ecotone region. The experiment was developed in the Sorriso-MT county in a Dystrophic Red Yellow Latosol. The treatments consisted of four bean cultivars: BRS Estilo, BRS Notável, BRS Ametista and BRS Pérola, in a total area of 9900 m2, where soil chemical and plant attributes were determined through 83 georeferenced sampling points. The statistical procedures used were: descriptive analysis of the data, geostatistical analysis and comparison of means by the “bootstrap” method. Most of the attributes presented moderate to high spatial dependence, with high spatial variability. The increase of potassium contents generated increases in productivity, while the increase in the incidence of nematodes, potential acidity and aluminum saturation in the soil resulted in a reduction. The highest productivity observed was of the cultivar BRS Pérola, indicating good aptitude for cultivation in this region.Keywords: Phaseolus vulgaris L., soil fertility, nematode, geoestatistics.
