| The study aimed to evaluate the nitrogen sources and doses application effects on the dry matter production and the sugar and alcohol gross yield of sugarcane (SP80-1816) in the cane-plant cycle in a dystrophic Red Oxisol. The experiment was conducted in the Fazenda Rio Paraiso II field, belonging to Usina Raízen, in Jataí - GO. The experimental design used was randomized blocks, arranged in a factorial scheme (2 x 4), with three replications. The treatments consisted of two nitrogen sources (urea and ammonium nitrate) and four nitrogen doses (0, 60, 120, and 180 kg ha-1). Dry matter variables were analyzed in sub-subdivided plots, as four evaluation periods were added (210, 250, 290, and 330 days after planting). The evaluation periods influenced... |

| Historically cultivated by small farmers, bean crops are now cultivated with varied levels of technology, including practices such as irrigation and direct sowing, as well as the soil management and traditional practices to increase productivity. Along with the adoption of these techniques, an increase in the usage of irrigation has occurred, which purports to meet the water requirements of the crop throughout its life cycle. The main objective of this work was to study the effects of different irrigation depths during two phases of the bean crop cycle and the behavior of cv. IAC-Alvorada during winter in the first and second year of direct sowing in Botucatu – SP, a southeastern region of Brazil. The experimental soil area is classified as a red... |
