Conteúdo: 	The calculation of node appearance is an important part of simulation models of crops with decumbent growth habit like muskmelon (Cucumis melo L.). The objective of this study was to adapt and evaluate a multiplicative non-linear model for estimating node appearance in muskmelon under greenhouse conditions. A series of experiments were conducted inside a plastic greenhouse in Santa Maria, RS, Brazil, using the muskmelon hybrid HY-MARK. A total of eleven planting dates were performed during 2002, 2003, and 2004. The number of visible nodes (NN) on the main vine was evaluated twice a week. The NN data from three planting dates were used to estimate the coefficients of the non-linear model and the plastochron (linear model), used as a comparison model. The NN data from the other eight planting dates were used as independent data for evaluating the models. The non-linear model had a good performance in simulating the main vine node number in this muskmelon hybrid, with a root mean square error of 2.4 nodes. The non-linear model was superior to the linear model as deviations (predicted-observed) were greater with the latter compared to the former model.
