The use of cover crops in no-tillage systems can change soil chemical properties and crop yield over time. Studies
using cover crops without the application of pesticides and soluble mineral fertilizers in no-tillage systems are
important to reduce production costs, the need for mechanization, and to improve nutrient cycling and crop
yield. The study aimed to evaluate how the use of different cover crops and the amount of dry matter produced
by such species affect soil chemical properties and onion yield. Onion crops were grown for eight years without
the use of pesticides and soluble mineral fertilizers in no-tillage system. The experiment was conducted from
2009 to 2016 in Ituporanga, state of Santa Catarina (SC), Brazil. The following treatments were used: barley
(2010)/black oat, rye, oilseed radish, oilseed radish + rye, and oilseed radish + barley or black oat, and a control
(consisting of weed species). A randomized block experimental design was used with eight replications. Plants
from each treatment were collected 100 days after sowing in plot areas of 0.75 m2 to determine dry matter yield.
The cover crops were desiccated and the onion seedlings were transplanted in July. The onion crops were
harvested every November to evaluate yield. Soil samples were collected at depths of 0− 10 and 10− 20 cm after
the onion harvest to evaluate soil chemical properties. The onion crop and residue deposition of single or
intercropped black oat, rye, and oilseed radish improved and maintained soil chemical properties. The lower dry
matter yield of cover crops found in the control treatment resulted in lower onion yields over the years. Cover
crops combined with soil tillage limited to the planting rows increased total onion yields and yield of larger-sized
onions as the system stabilized over time. MenosThe use of cover crops in no-tillage systems can change soil chemical properties and crop yield over time. Studies
