Conducting a field study to investigate the effects of foliar and soil fertilization with copper on the nutritional and physiological parameters and grain yield of common bean. The experimental design was a randomized block, in a 2 x 5 factorial scheme. The first factor was the site of application of copper fertilization. The second factor was copper doses: 0, 1, 2, 3, and 4 kg ha-1 (6 replicates). The following were evaluated: leaf nitrogen and copper contents, relative chlorophyll index (RCI), gas exchange, photochemical efficiency of photosystem II, and grain yield. The data were subjected to analysis of variance and F test (p-value < 0.05), using the Scott & Knott for qualitative data and polynomial regression for quantitative data. Leaf Cu content was higher with soil application (4% and 28%), both at 24 and 45 DAE, respectively. Net photosynthesis reached a maximum index of 18.77 µmol m-2 s-1 with foliar Cu fertilization at the dose of 4 kg ha-1. The application of 2.0 kg ha-1 Cu was the one that led to the highest grain yields; however, soil application stood out with a yield about 12% higher of the foliar. Soil fertilization proved to be more efficient in terms of Cu absorption and RCI rates, improving grain yield (12%) in relation to foliar, especially at the dose of 2 kg ha-1. The dose of 2 kg Cu ha-1 provided the best differential profit, reaching US$ 581.96 ha-1 and US$ 503.01 ha-1 for soil and foliar application, respectively.

“…These elements have little mobility in the soil, therefore, successive LSM applications have been associated with accumulations in the surface layers (Formentini et al, 2015;De Conti et al, 2016;Oliveira et al, 2017). Cu has a high affinity for forming stable complexes with functional groups of soil organic matter (De Conti et al, 2016), while Zn is primarily adsorbed on surface functional groupings of mineral particles, such as iron oxides (Grohskopf et al, 2016b). Furthermore, the pH of soil solution affects the solubility of both elements (De Conti et al, 2016).…”

Chemical and physical properties of soil can be altered with the successive application of liquid swine manure (LSM), also known as slurry. Therefore, monitoring the impact of LSM is essential to an assessment of the potential agronomic and environmental benefits and risks associated with management practices. The aim of this study was to evaluate the effects of LSM on the chemical and physical attributes of soil under pasture (Cynodon spp.), located in southern Brazil. Four areas were sampled: three areas cultivated with Cynodon spp. pasture with successive applications of 200 m 3 ha -1 y -1 of LSM for three, eight and 15 years; and untreated native forest as a reference. The soil attributes evaluated were: organic carbon (OC), active (pH water) and potential acidity (H + Al + 3 ), nutrient availability (i.e., P, K, Ca, Mg, Cu and Zn), soil bulk density, macro, micro and total porosity. Successive applications of LSM on pasture reduced soil active acidity, and increased the soil organic C and plant-available N, P, Ca, Mg, Cu and Zn contents. These effects were more intense with time and in the shallowest layers, i.e. 0-10 cm.Excessive increases in P, Cu and Zn in the soil should be carefully monitored to minimize the contamination risks to soil, ground and surface waters. Soil physical attribute changes were more associated with land use (pasture versus native forest) than LSM use, and LSM applications induced slight improvements in the soil structural quality over time.

Componentes De Produção De Feijoeiro Sob Adubação Mineral, Orgânica E Cúprica

ResumoO feijoeiro é uma das fontes de proteína da população brasileira, sendo seu cultivo bastante difundido em todo território nacional. Frequentemente, a feijoeiro tem sido cultivado sem o uso de tecnologias como adubação e irrigação, especialmente entre os pequenos produtores, o que se reflete diretamente em baixa produção e qualidade do produto. Nesse sentido, faz-se necessário estudar o ganho de produção que os agricultores teriam com a utilização de técnicas acessíveis como a adubação orgânica. Diante do exposto, objetivou-se avaliar as variáveis biométricas e de produção do feijoeiro cultivado com adubação orgânica ou mineral, na presença e ausência de adubação cúprica. O experimento foi realizado em blocos casualizados com 8 tratamentos e 3 repetições. Os tratamentos foram: 1. Testemunha (T); 2. Composto orgânico (CO) (16 t/ha); 3. Adubação mineral (AM) (N-P 2 O 5 -K 2 O: 50-80-20); 4. Composto orgânico + Adubação mineral (CO + AM); 5. Testemunha + Cu (T + Cu); 6. Composto orgânico + Cu (CO + Cu); 7. Adubação mineral + Cu (AM + Cu); 8. Composto orgânico + Adubação mineral + Cu (CO + AM + Cu). As plantas foram avaliadas quanto à altura, número de folhas e diâmetro do caule, número de vagens, tamanho médio das vagens, produtividade e peso de 100 grãos. A produção de feijão, o número de vagens e o peso de grãos por planta foram semelhantes independente do tipo de adubação aplicada, sendo melhor que a testemunha, sem adubação. Os teores de N e K na folha diagnóstica das plantas de feijão foram maiores nas plantas que receberam adubação mineral e adubação orgânica + mineral, já os teores de P e Cu não foram influenciados pelos tipos de adubação. Palavras-Chave: Phaseolus vulgaris, composto orgânico, nutrição IntroduçãoO feijão é um dos alimentos mais consumidos pelos brasileiros sendo uma importante fonte de proteínas e vitaminas. Os grãos de feijão do tipo comercial carioca representam a maior parte do mercado consumidor no Brasil, e o tipo preto é o segundo grão mais comercializado no país
