“…The increase in the proportion of forage in silage also resulted in higher values for the buffering capacity (Figure 1b), showing a linear increase up to the maximum dose of forage. This occurred because tropical forages have a higher buffering capacity than annual crops (Souza et al, 2019). According to S. S. Oliveira et al (2020), forage grasses have a high buffering capacity and a low content of soluble carbohydrates; this can influence pH values, as observed in this study.…”

This work aimed to evaluate the dynamics of agro-economic efficiency in combinations of vegetable cowpea and radish cultivars in strip-intercropping systems through agronomic, economic and competition indices tested by the Hsu test in a semi-arid environment. The experimental design was a completely randomised block with eight treatments and four replications. The treatments consisted of combinations of four cowpea cultivars, BRS Tumucumaque, BRS Cauamé, BRS Guariba, and BRS Itaim, with two radish cultivars, Crimson Gigante and Zapp. In each block, individual plots of these cultivars in single cultivation were planted as additional treatments to obtain the system indices. The indices of agronomic and economic efficiency and of competition evaluated were land equivalent ratio (LER), actual yield loss (AYL), land use efficiency (LUE%), score of the canonical variable (Z), gross income (GI), net income (NI), rate of return (RR), corrected monetary advantage (CMA), competitive ratio (CR) and the aggressivity of radish over cowpea (Ar) and cowpea over radish (Avc). The cowpea cultivar BRS Tumucumaque, when combined with the radish cultivar Zapp, provided the highest agro-economic efficiency of the intercropped system in a semi-arid environment. The complementarity and sustainability of the intercropping systems of cowpea and radish were observed in the results of the Hsu test applied to the indices of agro-economic efficiency and of competition. Radish was the dominant crop.

“…Between the two forage silages, the 100% Paiaguas palisadegrass silage had a 12% higher crude protein than the 100% Ipypora grass silage. This was due to the morphological structure of Paiaguas palisadegrass, which has a high leaf:stem ratio than Ipypora grass and thus generates better-quality forage (Epifanio et al, 2019;Souza et al, 2019).…”

“…However, the lowest production of DM was obtained by Paiaguas palisadegrass monocropped forage system, demonstrating that the intercropping has contributed for the rise of DM production in 110.6; 127.9 and 48.9%, in the rows, inter-rows and oversown intercropped, respectively. Several studies have evidenced the benefits of producing silages from intercropping systems (Ribeiro et al, 2017;Cruvinel et al, 2017;Souza et al, 2019;Oliveira et al, 2020).…”

“…BRS Paiaguas is a great option, the plant attends all the requirements needed in different systems of production, encompassing different technological levels (Costa et al, 2016). Besides that, the forage has been used for the production of silage in integrated systems, allowing great results (Santos et al, 2016;Costa et al, 2018;Souza et al, 2019;Oliveira et al, 2020). Cruvinel et al (2017) reported that the silage of additive sunflowers with tropical forages are able to bring great benefits to the quality of the silage, for example, decrease in the content of ethereal extract, in the fibers of acid detergents, lignin, in addition to the production of silage in the off season, with good quality and with sufficient amount for nutritional maintenance of ruminants.…”

The objective of this study was to evaluate dry mass production, fermentative parameters and chemical and bromatological composition of sunflower silage and Paiaguas palisadegrass silage in monocropped and intercropping in different forage systems. The experimental design consisted of randomized blocks, with four replicates. The treatments consisted of silage forage systems: sunflower monocropped; Paiaguas palisadegrass monocropped; sunflower row-intercropped with Paiaguas palisadegrass; sunflower inter-row intercropped with Paiaguas palisadegrass; and sunflower oversown and intercropped with Paiaguas palisadegrass, totalizing 20 experimental silos. Sunflower and Paiaguas palisadegrass were harvested at 110 days after planting at 20 cm from the soil for silage, using brush cutter. The silos were opened after 53 days of fermentation. The rows and inter-row intercropped systems contributed to increase the mass production of the ensiled material. The monocropped sunflower silage had higher values of pH, ethereal extract and acid detergent fiber and lower values of titratable acidity and dry matter, crude protein, neutral detergent fiber and in vitro dry matter digestibility values. The silages of the sunflower intercropped with Paiaguas palisadegrass in forage systems of crop-livestock integration presented better fermentative and bromatological characteristics, guaranteeing an adequate fermentative process and nutritional quality. In this way, the intercropping of these two forages potentiates the production of silage for feeding of ruminants during the period of forage shortage.

“…The consortium with sorghum did not positively influence the fraction of CP, because the highest values were recorded in maize monocultures (Agri 340 and Agri 320), also presenting the highest estimates of TDN (62.41%) in relation to other cultivation systems (Table 2). Regarding EE it is possible to observe an average value of 2.14% for cultivation systems (Table 2), these low estimates of EE often observed in C 4 grasses (Souza et al, 2019).…”

Maize and forage sorghum crops have a relevant economic importance in Midwest Brazil and there is a need for more information for their intercropping as a strategy for the farmers to reduce inputs. The objective of this work is evaluate if forage sorghum and maize intercropping effects agronomic traits, the bromatological characteristics of silage from the consortium at different times of silo openings, and the economic viability of all crop systems. This experiment was carried on in the field with seven treatments, consisting of monoculture and intercropping of corn and sorghum hybrids. Monoculture of sorghum Agri 001 and maize Agri 320, as well as in maize Agri 320, Agri 340 and Agri 104 intercropped with sorghum Agri 001 had the highest biomass yield. Intercropped maize did not have lodging, reduction in height, nor decrease in the first ear height in relation to the intercropped plants. Maize hybrids intercropped with sorghum led to a better fermentation pattern of silages, reducing ammonia concentrations. However, due the higher contents of NDF and the lower TDN contents of sorghum, nutritional values of intercropped silages were generally smaller than when they were composed only with maize. It was observed that the monoculture of sorghum Agri 001 for silage showed a higher profit compared to the other treatments.
