| The impact of agro-industrial organic wastes in the environment can be reduced when used in agriculture. From the standpoint of soil fertility, residue applications can increase the organic matter content and provide nutrients for plants. This study evaluated the effect of biological sludge from gelatin industry on the chemical properties of two Ultisols (loamy sand and sandy clay) and an Oxisol (clay). The experiment lasted 120 days and was carried out in laboratory in a completely randomized design with factorial arrangement, combining the three soils and six biological sludge rates (0, 100, 200, 300, 400, and 500 m³ ha-1), with three replications. Biological sludge rates of up to 500 m³ ha-1 decreased soil acidity and increased the effective cation... |

| ABSTRACT Foliar fertilization is an important agricultural technique that has stood out for its ease of use and can contribute to the production of high-quality and -vigor cashew seedlings. The objective of this study was to evaluate the effect of foliar fertilizer rates and time of application on ‘BRS 226’ dwarf cashew seedlings after grafting. The experiment was carried out in a completely randomized design, with five treatments and 24 replicates. Each experimental unit consisted of one plant. The commercial product (NPK 20-20-20) was used at the recommended rate for fruit crops in general, 2.5 g L-1. Foliar fertilizer applications at 45 and 60 days after grafting (DAG), with 50% of the recommended rate (1.25 g L-1), or at 80 DAG, with 100% of the... |

| Abstract Knowledge on the amounts of nutrients accumulated by pitaya in its different development stages allows defining the periods in which the essential elements are most required, thus contributing to the elaboration of rational fertilization programs for the crop, reducing production costs. This study aimed to evaluate the growth and nutritional requirement of red pitaya, estimating the accumulation of macro and micronutrients by the plants and determining the periods in which the greatest accumulations occur, as well as the relative growth rate and the relative nutrient absorption rate. Pitaya seedlings were planted in pots containing Argissolo Vermelho-Amarelo Eutrófico (Ultisol) and grown in the open air. The experimental design was randomized... |

| O objetivo deste trabalho foi avaliar clones de cajueiro como porta-enxertos para quatro genótipos-copa. Foram avaliados como porta-enxertos os clones CCP 06, CCP 09, CCP 76, CCP 1001, Embrapa 50, Embrapa 51, BRS 189, BRS 226, BRS 253, BRS 265, BRS 274 e BRS 275 e, como copas, os clones CCP 76, BRS 189, BRS 226 e BRS 274. Aos 60 dias após a semeadura, os porta-enxertos foram avaliados quanto às características biométricas e quanto às taxas de germinação e de aptidão à enxertia. Aos 80 dias após a enxertia, foram avaliadas as taxas de sucesso da enxertia, a aptidão para o plantio e as características biométricas das mudas. Houve correlação negativa entre massa de semente e taxas de germinação e de aptidão à enxertia. BRS 226, BRS 253 e BRS 274 apresentaram... |
