“…Silage made at once cut during season had greater NDF and ADF concentrations than the other cutting treatments. Many research workers (Geren et al, 2014;Daur, 2016;Atis et al, 2019) emphasized that hay or silage made by wizened grass is not a good option to feed livestock due to the lower quality. On the other side, some researchers emphasized that if managed well (plant age, cutting height, etc.)…”

This study was conducted in Bornova experimental fields of Department of Field Crops, Faculty of Agriculture, University of Ege, Turkey during 2015 and 2016, in order to determine the effect of six different cutting intervals (30-, 60-, 90-, 120-, 150-and 180-days) on the forage yield and some quality properties of giant king grass (Pennisetum hybridum). The experimental design was in complete randomized blocks, with three replications. 6 years old, Paraíso cultivar of giant king grass (GKG) was used as crop material. Some characteristics were measured such as dry matter (DM) yield, concentrations of crude protein (CP), NDF and ADF. Results indicated that there were significant effects of cutting intervals on the yields and some silage quality characteristics of GKG, and, metabolisable energy and relative forage values decreased as inter-cutting interval increased. It was recommended that the production of GKG using 60-day intervals were the most successful cutting frequency regarding the forage yield and silage quality to the regions with Mediterranean-type climates under irrigation.

“…The same trends were also found for other tested grasses such as buffelgrass, bell Rhodes grass and Kleberg bluestem. ( Daur, 2016 ) also found that nitrogen content in blue panicgrass shoots declined by 7% when harvested after flowering compared to the early stage before flowering. The same trend was found by ( Mirza et al., 2002 ) where nitrogen content in blue panicgrass and other tested grass shoots declined with the advancement of growth stages.…”

“…(2015) , who reported that NDF and ADF contents increased by 6% for 30 days compared to 15 days. Furthermore, Daur (2016) reported that NDF and ADF content in blue panicgrass was about 59 and 31% before flowering (35 days) and increased to 72 and 38%, respectively, after flowering (45 days). A negative relationship between ash and crude protein, with crude fiber, NDF, and ADF, was reported in several other studies.…”

Salinity has become a major issue in various parts of the world negatively impacting agricultural activities and leading to diminished crop potential and lower yields. Such situation calls for urgent interventions such as adopting salt-tolerant crops to fill the gap in food and feed availability. Blue panicgrass (Panicum antidotale Retz.) is a promising salt-tolerant forage crop that has shown an appropriate adaptation and performance in the saline, arid, and desertic environments of southern Morocco. However, for obtaining a highest forage productivity with nutritional quality, optimization of the cutting interval is required. Thus, the objective of this study was to determine the optimal cutting time interval allowing high forage production and quality under high salinity conditions. This experiment was conducted over one entire year covering the summer and winter seasons. The effect of five cutting time intervals on selected agro-morphological traits, crop productivity, mineral nutrient accumulation, and forage quality of blue panicgrass in the region of Laayoune, southern Morocco. The finding of this study recommend that cutting blue panicgrass every 40 days maximized the annual fresh and dry forage yield as well as the protein yield, which reached 74, 22, and 2.9 t/ha, respectively. This study also revealed a significant effect of the season on both productivity and quality. However, forage yield declined during the winter and increased during the summer, while protein content increased during winter compared to summer. The mineral nutrient partitioning between shoots and roots, especially the K+/Na+ ratio, indicated that blue panicgrass has salt tolerance mechanism as it excluded sodium from the roots and compartmentalized it in the leaves. In conclusion, there is a potential of blue panicgrass on sustaining forage production under salt-affected drylands, as demonstrated by the response to two key questions: (a) a technical question to farmers for its adoption such as at which interval should blue panicgrass be harvested maximizing both forage yield and quality? And (b) a scientific question on how does blue panicgrass maintain high K+/Na+ ratio to cope with salinity stress?

The soil solution is the compartment where plants uptake nutrients and this phase is in equilibrium with the soil solid phase. Changes in nutrient content and availability in the soil solution can vary among soil types in response to humic acid concentrations, thereby affecting Brachiaria growth. However, there are no studies demonstrating these effects of humic acid application on different soil types and how they affect Brachiaria growth. Thus, the aim of this study was to evaluate the effects of humic acid concentrations (0, 5, 10, 25, and 60 mg kg−1 carbon-humic acid) on Brachiaria brizantha growth and soil solution properties of contrasting tropical soils. Plants were grown for 35 days in greenhouse conditions in pots containing Sandy Entisol, Clayey (Red Oxisol), and Medium Texture (Red-Yellow Oxisol). Soil solution was assessed for pH, electrical conductivity (EC), carbon, and nutrient content. Shoot and root dry matter, as well as macro and micronutrients accumulation in the shoot, were determined. In a soil type-dependent effect, pH, EC, and concentrations of nutrients in solutions changed in response to carbon-humic acid concentration. In the less-buffered soils, Sandy Entisol and Red-Yellow Oxisol, the addition of 30–40 mg kg−1 carbon-humic acid increased root proliferation by 76–89%, while Brachiaria biomass produced in all soils increased by approximately 30%. Levels of carbon in solution were high (>580 mg L−1) and varied depending on the investigated soil type. Though solution carbon contents did not appear to be a driving factor controlling the positive effects of humic acid concentrations on Brachiaria dry matter, there was a direct relationship between other properties and nutrient content in the soil solution, and Brachiaria dry matter production.
