Hydroponic forage is an alternative to feed the animal in times of drought quickly. Thus, the objective of this work was to evaluate the development of hydroponic forage of corn and millet irrigated with mineral and organic solutions during the winter season in the Cerrado-Pantanal ecotone, seeking to determine the species and the most suitable solution for the region at that time. The experimental design was in randomized blocks, in a split plot scheme. The plots were the solutions (mineral and organic) and the subplots were the populations of corn, millet and black mucuna and their respective proportions, totaling 12 treatments, with four replications. At harvest, the production of green and dry matter production was carried out and a bromatological analysis of the aerial part and substrate was carried out, determining crude protein, neutral detergent fiber, acid detergent fiber and mineral matter. The chemical evaluation of the organic solution was carried out in a fertigation analysis laboratory. Corn forage under mineral solution irrigation obtained better crude protein contents. The substrate that obtained the highest crude protein and the lowest fiber content was in the subplot with 100% millet for both solutions.

Entre os fatores que influenciam na produtividade do feijoeiro, a precipitação e a nutrição são consideradas limitantes. O objetivo deste trabalho foi avaliar o manejo da irrigação, adubação nitrogenada e a inoculação de sementes, no feijoeiro de inverno, em Aquidauana - MS. O trabalho foi realizado na área experimental da Universidade Estadual de Mato Grosso do Sul, utilizando a cultivar TAA Dama com semeadura em 24 de maio de 2018. O delineamento experimental foi em blocos casualizados, em esquema de parcelas subsubdivididas, com quatro repetições. As parcelas foram os manejos de irrigação Penman-Monteith e tensiometria. As subparcelas foram com e sem inoculação de Rhizobium tropici semia 4077 e, nas subsubparcelas, foram empregadas as doses de nitrogênio em cobertura (50, 100, 150 e 200 kg ha-1 e um com ausência de nitrogênio). Foram avaliados o número e massa seca de nódulos, número de vagens por planta, massa média de 100 grãos, número de grãos por vagens, produtividade de grãos, eficiência no uso da água. Maiores doses de adubação nitrogenada em cobertura proporcionam maiores produtividades de grãos e eficiência no uso da água pelo feijoeiro. A presença ou ausência de inoculação não influencia na produtividade de grãos do feijoeiro irrigado.

Irregular rainfall can restrict crop development, so irrigation of pastures serves as a strategy to intensify grass-fed animal production systems. Due to the direct relationship between the availability of soil water and nutrients, the objective was to evaluate the nutrient content in forages irrigated by a central pivot system. This work was carried out in the experimental area of irrigated agriculture at the State University of Mato Grosso do Sul, in Aquidauana-MS, Brazil. The experiment was setup in a completely randomized design, with five replications, in subdivided plots. The treatments of the plots were irrigated and non-irrigated, and the treatments of the subplots were the forages Urochloa brizantha cv. Xaraes, Pennisetum purpureum cv. Napier, Panicum maximum cv. Mombasa and Urochloa ruziziensis cv. Ruziziensis. Foliar concentrations of the nutrients Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Sulfur (S), Boron (B), Copper (Cu), Iron (Fe), Manganese (Mn) and Zinc (Zn) were evaluated. Statistical analyses performed included analysis of variance, Tukey test at p <0.05 and linear correlation matrix at p <0.05 and p <0.01 between nutrients and productivity. Irrigation results in higher levels of the macronutrients P, K and Mg, and Fe and Mn micronutrients in forages. The nutrients that correlated with productivity were P and Fe, which both presented negative correlation. The nutrients correlated better with each other than with forage productivity.
