ABSTRACT Potassium (K) is one of the most highly accumulating nutrients in Eucalyptus and, consequently, is heavily exported by the harvesting of wood. Moreover, its availability in the soil in most Brazilian plantation areas is very low, especially in the regions of the Cerrado biome, which has soils with low natural fertility and marked water deficits, implying a lack of nutrient supply and, consequently, a less efficient water use. Our objective was to evaluate the effects of K fertilization on […]

To achieve high wheat yield, correct management of N fertilization and the use of high yield potential cultivars are necessary. The aim of this study was to evaluate the effects of different application rates and sources of N, applied totally at sowing or in topdressing, on grain yield and yield components of two irrigated wheat cultivars under a no-till system, grown in a Cerrado (Brazilian tropical savanna) region of low altitude. A randomized block design was used in a 5 […]

Sugar cane plays an important economic-social and political role in Brazil. This study aimed to evaluate the effect of manganese doses and sources on sugar cane. The experiment was conducted on the Sitio Fujimoto, an area administered by the Distillery Vale do Paraná S/A Alcohol and Sugar in Suzanápolis, São Paulo state. The experiment was arranged in a randomized block, 5 x 3 factorial design, with 5 manganese rates (0, 2.5, 5.0, 7.5 and 10.0 kg ha-1) and 3 sources […]

High wheat yields require good N fertilization management. The objective of this study was to evaluate the effects of different N applications at sowing using Entec (N source with nitrification inhibitor) and urea (traditional N source) at covering, on four wheat cultivars. The experiment was conducted in a randomized block design in a factorial scheme, with four replications, at the Experimental Station of the Faculdade de Engenharia de Ilha Solteira – UNESP, on a dystrophic, epi-eutrophic alic Red Latosol with […]
