| O objetivo do presente trabalho foi avaliar a qualidade de mudas de moringa em função da posição das sementes no fruto e da concentração de nutrientes na solução de fertirrigação. Realizou-se um experimento seguindo o delineamento inteiramente casualizado, com os tratamentos arranjados em esquema fatorial 3 x 4, sendo três posições de sementes no fruto (basal, mediana e apical) e quatro doses de nutrientes (0, 50, 100 e 150% da dose padrão), com quatro repetições. Foram avaliados os seguintes parâmetros: altura (ALT), diâmetro do coleto (DC), número de folhas, matéria seca da parte aérea (MSPA), matéria seca do sistema radicular (MSSR) e matéria seca total, relação ALT/DC, MSPA/MSSR e índice de qualidade de Dickson. Os dados foram submetidos à análise de... |

| The objective of this study was to evaluate the effects of a biostimulant on gherkin seeds, cultivar Liso de Calcutá, under conditions of salt stress. A split-plot experimental design with five replications was used; the main plot was represented by two levels of irrigation water salinity (0.5 and 3.5 dS m-1), and the subplot was composed of five biostimulant doses applied as a seed treatment (0, 5, 10, 15, and 20 mL kg-1). The following variables were evaluated: the number of leaves; number of branches; length of the largest branch; leaf, stem, fruit and total dry matter; number of fruits; average fruit weight; and fruit production. The values of all analyzed variables decreased with an increase in irrigation water salinity regardless of the biostimulant... |

| Bell peppers are sensitive to salinity; therefore, it is necessary to find alternatives to reduce saline stress. An experiment was conducted in a greenhouse at Federal Rural University of the Semi-Arid Region, in Mossoró, Rio Grande do Norte State, Brazil, to evaluate the effects of salinity and K+/Ca2+ ratios on bell pepper production. The experimental design consisted of randomized blocks in a 5 x 4 factorial scheme with four replicates, corresponding to five K+/Ca2+ ratios (F1 = 3.3/1, F2 = 2.8/1, F3 = 2.2/1, F4 = 1.8/1, and F5 = 1.5/1) and four salinity levels in the nutrient solution using NaCl (1.75, 3.25, 4.75, and 6.25 dS m-1). The following parameters were evaluated: the number of fruits (total, marketable and unmarketable), the mean weight of... |
