| Powdery mildew, caused by Podosphaera xanthii, is an important disease of melon in the Brazilian Northeast. The objective of this work was to evaluate the reaction of families, lines and cultivars of melon to P. xanthii. Two experiments in simple lattice were carried out under field conditions in the municipalities of Mossoró and Baraúna to evaluate 144 families. In a greenhouse, an experiment was carried out in a completely randomized design to evaluate 19 lines and the cultivars Yellow Queen, Chilton and Hy Mark. Disease was assessed by a severity scale. There was genetic variability among families. The families 4, 5, 11, 14, 18, 23, 33, 42, 101, 112 and 140 were identified in both sites as resistant. The lines LOF-027, LOF-105, LPS-124, MEL-008 and... |

| The aims of the present study were to assess the reaction of melon accessions to crater rot, caused by Myrothecium roridum, and study the inheritance of resistance. In the first experiment, 30 melon accessions from northeastern Brazil were assessed in a randomized block design with two replicates. Each plot was formed by a row of 12 plants, from which three fruits were sampled and used for inoculation. Each fruit was inoculated at four equidistant sites on the surface. Ten wounds were made at each site to an approximate depth of 3.0 mm, to which 0.05 mL of conidial suspension was placed at a concentration of 10(6) spores mL-1 of sterilized distilled water with the aid of a pipette. The fruits were placed on Petri dishes and enveloped in polyethylene bags... |

| In Rio Grande do Norte, the melon growers have been using the row cover on the roof of the plants to start flowering in order to reduce the population of insect pests that cause severe losses, rising production costs, especially with the application of defensive. Thus, it is important to know the best time to remove the row cover because, due to its use, it is assumed that there are changes in the physiological response of plants. In order to evaluate the growth and yield of the melon plants 'Acclaim' cultivated under protection agrotextile (TNT) for different periods, a trial was conducted at the Universidade Federal Rural do Semi-árido, Mossoró, Rio Grande do Norte state. The experimental design was a randomized complete block, with four replications, in... |

| A rizoctoniose, ocasionada pelo fungo Rhizoctonia solani, é uma doença frequente em áreas cultivadas, intensivamente com melão (Cucumis melo) no nordeste brasileiro. O objetivo do presente trabalho foi identificar e caracterizar morfologicamente fontes de resistência de meloeiro a R. solani. No primeiro ensaio foi avaliado o nível de resistência de 22 acessos de meloeiro coletados no nordeste brasileiro, frente ao isolado RS-21. Os acessos resistentes do primeiro experimento juntamente com 13 linhagens do cruzamento ACP x AF-646 foram avaliados para reação aos isolados RS-22 e RS-23 em um segundo ensaio. Utilizou-se o delineamento inteiramente casualizado com cinco repetições. Foram identificados como fontes de resistência os acessos T-A-08, T-A-09, T-A-19... |

| O trabalho teve por objetivo avaliar a conservação de melão Cantaloupe cultivado em diferentes doses de nitrogênio e potássio via fertirrigação. Para isto, foi realizado o plantio do melão cultivar 'Caribbean Gold' em Mossoró-RN. A adubação foi realizada em kg/ha formando os respectivos tratamentos de N e K2O: (0; 0), (0; 83), (0; 365), (0; 828), (38; 0), (38; 83), (238; 0), (238; 365), (238; 828), (666; 0), (666; 365) e (666; 828). Os frutos foram colhidos aos 60 dias após o transplantio e, após a limpeza, pesagem e tratamento antifúngico do pedúnculo, uma amostra de 12 frutos foi avaliada no tempo zero e os demais foram identificados, revestidos em sacolas de PEBD Life Span, acondicionados em caixas de papelão e armazenados em câmara fria com temperatura... |
