| ABSTRACT Several complications can arise, either directly or indirectly, from implementation of measures to correct soil acidity in established fruit orchards, such as impaired roots, lower root volume, risk of plant infection, propagation of diseases, promotion of pest development (especially nematodes), and soil disaggregation and compaction. These factors can have a negative effect on crop yield. Therefore, it becomes critical to implement an effective method of neutralizing soil acidity, especially at the level of the tree roots. To assess the effect that the rates and forms of limestone applied on the soil surface have on soil fertility and on nutrition and yield of guava, an experiment was conducted in a commercial orchard. A randomized block... |

| Este trabalho teve por objetivo avaliar a vida útil de cinco híbridos de melão cv. amarelo (AF-7100, AF-1498, AF-5107, AF-4945 e AF-1805) produzidos no Agropolo Assu-Mossoró-RN. Após atingido o estádio de maturação, os frutos foram colhidos e conduzidos ao Laboratório de Pós-Colheita da Universidade Federal Rural do Semiárido (UFERSA), onde se retiraram ao acaso 12 frutos de cada híbrido para caracterização no tempo zero. Em seguida, os demais frutos foram pesados, identificados e armazenados em câmara refrigerada regulada a 10±1ºC e 90±2% UR, onde permaneceram por 7; 14; 21; 28; 35; 42; 49; 56; 63 e 70 dias. Em cada intervalo de tempo, avaliaram-se nos frutos: perda de massa, firmeza da polpa, aparência externa e interna, pH, acidez titulável, sólidos... |

| 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... |
