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 […]

Nitrogen is an important nutrient, due to its soil dynamics and crop demand. The amount of N supplied by the soil is however frequently insufficient, and N fertilization is required to obtain maximum yields. This study was conducted with the objective of evaluating different sources and periods of N application in no till wheat. A randomized block design was used in a factorial scheme 2×6 with four replications. The treatments consisteded of the combination of two N sources: Urea and […]
