Abstract
Selection of stem cuttings is an important step for production of high-quality seedlings by rapid multiplication method. This study aimed to assess the sprouting capacity of cassava stem cuttings of different diameters. Experiments were conducted at five planting seasons (June, July, August, September, and October) under a completely randomized design in a factorial scheme (5 × 2), with ten treatments and 20 replications. Treatments consisted of combinations between planting seasons and stem cuttings with diameters lower (15 to 19.99 mm) and higher (20 to 25 mm) than 20 mm. Each stem cutting was measured regarding length, diameter, and weight. The mean number of days for emergence, percentage of survival, and sprouting index were assessed at each plot. Planting of stem cuttings with diameter between 20 and 25 mm in September was adequate for obtaining cassava cuttings for the rapid multiplication method.
