- Split-plot
- Description
- An experiment was set up at the Pergamino Experimental Station of the Instituto Nacional de Tecnología Agropecuaria (INTA) introducing fall-winter grasses (rescue grass (Bromus unioloides L.), ryegrass (Lolium multiflorum L.), oats (Avena sativa L.), barley (Hordeum vulgare L.)), crucifers (rape seed (Brassica napus L.), forage radish (Raphanus sativus L.)), a legume (vetch (Vicia sativa L.)) and an oats+vetch mixture as cover crops in a maize-soybean rotation under no tillage with and without N fertilization of maize. A control without cover crop was included and it was maintained without weeds during the cover crops growing season using chemical control.
- Design description
- The experimental design consisted of three completely randomized blocks with split plot; the main plots (30 x 10 m) corresponding to the cover crop treatment and the subplots to the fertilizer treatment (0 and 32 kg N ha-1 at V5-6 stage of maize).
