摘要

The use of nitrogen (N) fertilization has been shown to increase the quality and production of cucumber. Thus, the goal of this workwas to evaluate crop management practices with and without shoot pruning and the application of N in a pickling cucumber cropunder greenhouse conditions. The experiment was conducted in a greenhouse at the Goiano Federal Institute, Urutaí Campus. Theexperimental design involved randomized blocks in a 2×5 factorial arrangement, with two different management treatments (withand without pruning) and five doses of N (0, 50, 100, 150 and 200 kg ha -1 N), with four replicates. The doses of N were split amongthree applications at 15, 30 and 45 days after plant emergence. Each plot contained ten plants with a 0.2-m spacing between plantsand a 0.8-m spacing between rows. The four central plants in each plot were evaluated, and the following assessments wereperformed: leaf N content, relative chlorophyll index, stem diameter, fruit length, fruit diameter, number of fruits, fruit fresh mass,fruit dry mass, shoot fresh mass, production per plant and total yield. The data were subjected to analysis of variance (F test) at the5% probability level, and when significant effects were observed for the N doses, regression analyses were performed.Management with and without pruning directly influenced the production of pickling cucumber. The doses of N influenced thedevelopment and yield of cucumber under greenhouse conditions.
