This research aimed to evaluated Cyperus rotundus development planted in different depths with and without imazapic and sugarcane straw. The experimental design was entirely randomized, analyzed in factorial outline 2 x 2 x 6, being constituted of 24 treatments represented by straw (2 levels); herbicide (2 levels) and planting depth (6 levels). The treatments were constituted by 25 tubers planted in 0, 2, 4, 6, 8 and 10 cm depths with and without imazapic (110 g ha-1) and sugarcane straw (15 t ha-1). The shoots were inhibited only until 60 days after imazapic application with and without sugarcane straw. The roots, tubers quantity and viability were reduced by treatments with straw absence and planted tubers in 0 cm superficial depth in presence or absence imazapic application.
Saccharum spp.; weed; imazapic
