“…The use of NTS increases the stability of crop production, with minimal environmental disturbance (Franchini et al 2012). However, the long-term sustainability of NTS requires the implementation of crop rotations, minimum soil disturbance, and the cultivation of species with high longevity of straw, such as those of the Urochloa genus (Silva et al 2004).…”

“…Therefore, the establishment of fodder grasses before soybean harvest is an alternative that can ensure adequate production of fodder during the period of low water availability. A strategy that can be successfully implemented without causing a significant reduction in the soybean yield is the intercropping between soybean and grass using a high-yield species, such as Urochloa (Silva et al 2004).…”

The integrated crop-livestock system is a key strategy for both grain and livestock production. The cultivation of grass species in between two soybean cropping seasons has been an important component of this system, in Brazil. Thus, this study aimed to evaluate the yield of glyphosate-resistant soybean cultivars intercropped with Urochloa species, under different forage management systems. A total of six experiments, consisting of three soybean cultivars (BRS 295 RR, BRS 316 RR, and BRS 294 RR) and two grass species (Urochloa ruziziensis and Urochloa brizantha), were established. For each experiment, four treatments (soybean only; grass only; soybean intercropped with a grass species, with the application of glyphosate to decrease the growth of grass; and soybean intercropped with a grass species, without growth suppression) were evaluated in a completely randomized experimental design, with four replications. For each experiment, only one soybean cultivar and one grass species were used. The grasses were sown in the soybean inter-rows at 27 days after sowing (DAS), while the glyphosate application to the treatment with grass suppression was performed at 84 DAS for the soybean or 57 DAS for the grasses. The yields of the three soybean cultivars were not significantly affected by either grass species, even though the shoot dry-matter yields for both of the intercropped grass species were high, though lower than the values obtained without the interference imposed by soybean.

“…Studies conducted by Crusciol et al (2012Crusciol et al ( , 2014 and Franchini et al (2014) showed changes in this variable between years or among genotypes. The average insertion height of the first pods ranged from 12.5 to 14.5 cm; however, no differences were observed between cultivation modalities, which is in alignment with Franchini et al (2014) and Crusciol et al (2014), but differs from Silva et al (2004) and Crusciol et al (2012). The average height of plants and of the insertion of the first pods are characteristics that vary between soybean genotypes and present some plasticity in relation to environmental changes (Crusciol et al, 2012;Franchini et al, 2014).…”

“…The delayed planting of the forage, besides reducing the potential forage competition, allows the application of herbicides for weed control before soybean emergence. If the grass develops more than expected, its growth can also be inhibited by applying herbicides (Cobucci & Portela, 2003;Silva et al, 2004).…”

“…The fasciculate root system of forages allows them to explore a larger volume of soil and gives them a greater water-extraction capacity than a plant with a pivotal root, such as soybean. In addition, the greatest effective depth of the root system of forage plants -1.0 to 1.5 m in comparison with 0.6 to 1.3 m for soybean -and the higher depletion factor of water availability - The application of herbicide dosages was indicated for intercropping with 'MG5' and ' Aruana' (Silva et al, 2004;Concenco et al, 2014) when the forage was competitive with soybean, with simultaneous planting. However, since herbicide tolerance varies among forages, it is necessary to study products and adjust doses to control the growth of the grass, so that the production of soybean is not compromised.…”

-The objective of this work was to evaluate soybean (Glycine max) grain yield and the establishment of perennial intercropped forages. Soybean was evaluated in sole crop and intercropped with the following forages: Megathyrsus maximus, Aruana and BRS Tamani cultivars; Urochloa brizantha, Xaraés, BRS Piatã, and BRS Paiaguás cultivars; U. decumbens; and U. ruziziensis. A randomized complete block design was used, with seven replicates, in the 2011/2012 and 2012/2013 crop seasons. In the intercropped system, the forages were sown 21 and 14 days after soybean emergence, in the first and second crop seasons, respectively. Grain yield did not differ for soybean in sole crop or intercropped, except for soybean + U. ruziziensis and soybean + 'BRS Paiaguás', which were less productive in the second year of evaluation. The 'BRS Tamani' forage was the most suited for intercropping with soybean, considering its morphological characteristics and its low competition potential. Soybean intercropped with perennial forages contributes to suppress weed growth and, overall, does not compromise soybean yield.

Effects of row spacing and intercrop on maize grain yield and forage production of palisade grass

et al. 2012

Intercropping of maize (Zea mays L.) with perennial forage, such as palisade grass [Brachiaria brizantha (Hochst. ex A. Rich) Stapf], provides large amounts of biomass that can be used as straw for no-tillage systems or as pasture for animal grazing. In addition, the use of narrow row spacing may increase maize grain yield. However, it is important to evaluate intercrops at different row spacing to avoid reductions in both maize and forage biomass production. The objectives of this field experiment during two growing seasons in Brazil were as follows: (1) to evaluate the influence of intercropping and row spacing on maize yield, leaf nutrient concentration, and plant population and development; and (2) to assess the influence of row spacing on palisade grass herbage mass and leaf nutrient concentration. The experimental design was a randomised complete block design in a 2 × 2 factorial scheme, with eight replications. The treatments comprised two row spacing distances (0.45 and 0.90 m) and two crop management types (maize monoculture and intercropped with palisade grass). The nutrient concentrations in the leaves of the maize plants were in the ideal range for this crop under all conditions studied. Plant height, height of first ear, and number of grains per ear were higher with the narrow row spacing. Maize grain yield was similar in both crop management types (10 301 and 9745 kg ha–1 for monoculture maize and intercropped, respectively). However, maize grain yield at the narrow row spacing was higher than that obtained with the wide row spacing (9948 v. 8905 kg ha–1). In contrast, row spacing did not affect the nutrient level or quality (crude protein concentration) of palisade grass. The amount of dry matter (DM) from palisade grass was lower at maize harvesting (4.7 Mg ha–1) and 90 days after harvesting (6.9 Mg ha–1) under narrow spacing. However, the amount of DM was similar at both row spacings at 120 days after maize harvesting (9.2 Mg ha–1). When there is no problem with water and nutrient availability, the use of maize and palisade grass intercropping under both row spacing conditions (0.45 and 0.90 m) provides an option for the production of forage DM without reducing the maize grain yield.
