“…Sweet sorghum silage is considered an energy food; however, its protein content is low (70.64 g kg -1 DM), which is a disadvantage of sorghum silage compared to tropical forage silages. Evaluating bagasse silages from sweet sorghum cultivars, Gomes-Rocha et al (2018) observed crude protein contents from 60.5 to 70.1 g kg -1 DM, which are close to those found in the present study in the pure sorghum silage.…”

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.

“…The relatively high values of dry matter recovery obtained in this study may be correlated with the low gas loss, which may represent up to 98.4% of the dry matter loss, mainly due to the undesirable fermentation, in which CO 2 is formed (Gomes-Rocha et al 2018).…”

This study aimed to evaluate the nutritional and fermentative potential of silage of the forage sorghum Ponta Negra irrigated with saline water. The bromatological characteristics, losses and fermentative profile of sorghum silages were observed. For the bromatological characteristics of the sorghum plant, a decreasing linear behavior was observed for the contents of dry matter and organic matter while a positive linear effect was verified for crude protein and mineral matter as the leaching fractions were increased (P < 0.05). A quadratic behavior was observed for nonfibrous carbohydrates, neutral detergent fiber, acid detergent fiber, and cellulose (P < 0.05). The pH values showed a quadratic effect (P < 0.05) with lower pH values observed at 15 days of silo opening for water depths of 10 and 15%. Regarding the silages, the leaching fractions provided differences (P < 0.05) for dry matter recovery, gas loss and effluent loss. A negative linear behavior for the contents of dry matter and organic matter and an increasing linear effect for mineral matter (P < 0.05). The highest concentrations of ammoniacal nitrogen were observed when irrigation was performed with a 10% saline water depth (P < 0.05).

The storage of forage to be offered at different times of the year are viable alternatives for all production systems, and sorghum biomass has been highlighted for this purpose. As preserved forage, it was hypothesized that sugarcane can contribute to the fermentation process. The objective was to evaluate the inclusion of different levels of sugarcane (0, 20, 40 and 60%) in the silage of three biomass sorghum genotypes (B012, B017 and B018). The material was ensiled using PVC silos and after 60 days the silos were opened and the contents of dry matter, mineral matter, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose, lignin, and hydrogen potential were determined. The experiment was conducted in a completely randomized design, in a factorial scheme with four replications. The data were analyzed through the analysis of variance followed by multiple comparison by Tukey's test (α < 0.05) and linear regression. The biomass sorghum genotypes responded satisfactorily to the fermentation process, resulting in quality silages. However, the inclusion of sugarcane did not improve the quality of the silages, and its inclusion in the silage of the genotypes evaluated is not recommended.
