“…Despite not interfering in corn development, this grass did not promote improvements in soil physical quality. Paschoal et al (2020), evaluating the soil structure by the visual method in this experiment, observed that the grass in T1 did not promote benefits in the physical structure of the soil due to the low development, and presented average visual score equal to the non-intercropping corn treatment. Reason why this treatment did not influence the variables observed in relation to non-intercropping corn (T5).…”

“…In Brazil, 32.8 million hectares are cultivated under no-tillage system (Soares et al 2021), being characterized by the double crop of soybean-corn, where soybean is grown in the summer and corn at the end of the season (Anghinoni et al 2021, Mendes et al 2018. The state of Paraná is one of the largest producers of second-crop corn, in which the north and western regions of the state are the main producers of this grain (Paschoal et al 2020).…”

The intercropping of corn with forage grasses increases soil cover and may improve soil structural quality. The objective of the study was to evaluate the soil structural properties and the development of second-crop corn intercropping with forage grasses under no-tillage system. The experiment was carried out in an area of Sítio Santo Antônio, located in the municipality of Borrazópolis, Paraná state, Brazil, on a Red Latosol with a very clayey texture. The experiment consisted of five treatments: corn + Urochloa brizantha cv. Marandu (T1), corn + Urochloa brizantha cv. Piatã (T2), corn + Urochloa brizantha cv. Xaraés (T3), corn + Urochloa ruziziensis (T4), and non-intercropping corn (T5). In the corn crop, the following characteristics were evaluated: plant height, first ear in insertion height, stem diameter, corn yield, dry mass of corn straw mulch, dry mass of grasses shoots and dry mass of grasses root. Dry mass of the aerial part and roots of the grasses were evaluated. In the 0-0.10 and 0.10-0.20-m soil depth, soil physical properties were also determined: tensile strength and friability, stability of aggregates, bulk density and total porosity, and degree of compactness. The treatments of corn in intercropping with grasses showed positive results regarding the stability of aggregates, reduction of bulk density and increase of total porosity in the 0-0.10-m soil depth. The intercropping of corn + U. ruziziensis showed the lowest values of degree of compactness and higher production of dry mass of the aerial part.
