Resumo: | The objective of this study was to evaluate the production of watermelon seedlings irrigated with saline waters and cultivated in different types of environments and substrates. The experimental design was completely randomized with split-split plots, in which the plot corresponded to two growing environments (EN1 = full sun and EN2 = 50% shade black net), the subplot to two types of irrigation water (IW1 = 0.8 and IW2 = 2.5 dS m-1) and the sub-subplot to four types of substrates (SB1 = vermiculite + coconut fiber, SB2 = manure + soil, SB3 = carbonized rice husk + soil, SB4 = biochar + soil), with four replicates of twenty-five seeds. The variables analyzed were: emergence percentage (EP), emergence speed index (ESI), mean time of emergence (MTE), number of leaves (NL), stem diameter (SD), seedling height (SH) and root length (RL), shoot dry mass (SDM), root dry mass (RDM) and total dry mass (TDM). The EN2 treatment provided better conditions for emergence and initial growth, and EN1 was also favorable to the emergence and initial growth of watermelon seedlings, when the substrates SB1 and SB2 were used. |

Objetivou-se com este trabalho avaliar a produção de mudas de melancia irrigadas com águas salinas e cultivadas em diferentes tipos de ambientes e substratos. O delineamento experimental foi o inteiramente casualizado com parcelas subsubdivididas, sendo a parcela os dois ambientes de cultivo (AM1 = pleno sol e AM2 = telado preto com 50% de sombreamento), a subparcela as duas águas de irrigação (AI1 = 0,8 e AI2 = 2,5 dS m-1) e a subsubparcela os quatro tipos de substratos (SB1 = vermiculita + fibra de coco, SB2 = esterco + solo, SB3 = casca de arroz carbonizado + solo, SB4 = biocarvão + solo), com quatro repetições de vinte e cinco sementes. As variáveis analisadas foram: porcentagem de emergência (PE), índice de velocidade de emergência (IVE), tempo médio de emergência (TME), número de folhas (NF), diâmetro do caule (DC), altura de plântula (AP) e comprimento da raiz (CR), massa seca da parte aérea (MSPA), massa seca da raiz (MSR) e massa seca total (MST). O tratamento AM2 propiciou melhores condições de emergência e crescimento inicial, já o tratamento AM1 também se mostrou favorável à emergência e crescimento inicial de mudas de melancia, quando utilizados os substratos SB1 e SB2.
