Sugarcane (Saccharum officinarum spp.) is a cultivar from the Poaceae family, and its cultivation is a very important socioeconomic factor, with most of the production destined for ethanol and sugar production and also as organic fertilizer and animal feed. The experiment was implemented and conducted between April 2022 and April 2023, in an area located at BR 020, Km 18, the climate is classified as seasonal tropical, characterized by two well-defined seasons: dry and rainy. The experimental area was prepared for conventional planting, with harrowing and subsoiling, planting was carried out manually on April 18, 2022, for planting fertilization, a dose of 600 kg ha-1 of NPK was applied in the formulation 04-30-16 throughout the experimental area. The experiment was carried out with 5 varieties of sugar cane as the main treatment and 2 planting spacings being the secondary treatments and 4 replications in a completely randomized block design (BDC) in a split-plot arrangement. The tested varieties were: V1 - RB867515; V2 - RB966928; V3 - TC4; V4 - RB92579 and V5 - CTC9001, the spacings were E1 - 1.50m x 0.9m and E2 - 1.40m x 0.5m. For varieties, the value of the statistic F (32.83) exceeds the critical value at the 1% probability level (5.41) it is significant at this level (P < 0.01), we reject the null hypothesis and conclude that the effect of variety differs from the productivity effect of the cultivar. For spacing, the value of the F statistic (10.79) exceeds the critical value at the 1% probability level (8.68) it is significant at this level (P < 0.01) , we reject the null hypothesis and conclude that the spacing effect differs from the cultivar productivity effect, for the Interaction (Spacing x Variety) the value of the F statistic (0.70) for interaction is lower than the critical value at the 5% probability level (3.06) it is not significant at this level (P > 0.05), therefore the null hypothesis cannot be rejected and we conclude that the effect of the factors spacing and variety act independently on the productivity of the cultivar.
