“…e present finding suggests that the earlier cutting date of Sudan grass coincides with higher tillering, which may stimulate more number of shoots per plant, respectively. ese results are comparable to those obtained by Sowiński and Szydełko [18], uranira et al [9], and Ibrahim et al [5]. Consequently, N fertilizer levels recorded significant differences in both seasons.…”

“…e highest LA obtained during late cutting dates could be due to extra growing time (seven more days after early cutting), which might have allowed for more vegetative growth and development. ese results are in consistent with those ascribed by Yagoub and Abdelsalam [22], Atis et al [10], and Ibrahim et al [5]. Regarding the influence of N fertilizer levels, data obtained (Table 3) showed highly significant differences among applied N levels in both seasons.…”

“…Mahmoud et al [19] reported similar findings, which emphasized the role of externally supplied N in enhancing the vegetative growth in sorghum forage crop. In addition, Ibrahim et al [5] reported relevant response in all the growth attributes and yield of this sorghum Sudan grass cultivar Giza-2 (Sorghum sudanense (Piper) Stapf.) under the N level of 45 kg N/fad/cut.…”

“…stands as an important short-term annual and summer season forage crop widely grown in Egypt to balance the desperate demands by the livestock industry. It is recognized among the most satisfactory summer forage resources cultivated under irrigation system in many of the arid and semiarid parts of the country [5]. Area cultivated with Sudan grass reached about 3500 ha producing 190913 tons, with average production around 9.2 tons/ha [6].…”

“…In this context, improving the growth, forage yield, and quality of Sudan grass requires the adoption of suitable agronomic practices among which cutting time and nitrogen fertilization are important [8,9]. Field observations and research findings have established that earlier cutting of sorghum plants would provide higher quality, while late cutting could produce higher forage yield [5,10,11]. Moreover, most farmers usually decide to harvest their forage crops more or less dependent on market demand without consideration to proper cutting time that can produce highest forage attributes [12].…”

Sudan grass is less sensitive to water shortage and produces large amounts of biomass. For these reasons, it is a promising summer forage crop for arid and semiarid regions where natural pastures are rare and water scarcity limits summer forage production. The aim of the present work was to investigate the influence of cutting date (early and late, for three cuts) and three nitrogen (N) fertilizer levels (35, 70, and 105 kg N/ha/cut) on Sudan grass (Sorghum sudanense (Piper) Stapf.). The study was carried out in the experimental farm of Faculty of Agriculture, Zagazig University, Egypt, during 2016 and 2017 summer seasons using a split-plot design. The results obtained revealed significant differences between the two cutting dates on growth, forage yield, and quality of Sudan grass. The late cutting date (56 days after sowing DAS and 42 days after the 1st cut) gave the highest values for almost all the growth characters, dry forage yield in addition to total dry yield (TDY) in both seasons. The highest number of shoots/plant (1.911), leaf area/plant (2841.6 cm2), and dry forage weight (g)/plant (76.65 g) were obtained by late cutting (56 DAS) with the application of 105 kg N/ha/cut. The lowest values of these characters were recorded with 35 kg N/ha/cut. Quality parameters were significantly affected by N levels during both seasons, while cutting date significantly affected the protein yield (kg/ha). The interaction result apparently indicated that the highest dry forage yield of Sudan grass (16.26 ton/ha) was achievable at the 1st cut with the application of the highest N level (105 kg N/ha/cut).

Most arid and semiarid areas are bare and greatly infested with intrusive wild species. Buffel grass (Cenchrus ciliaris L.) and Sudan grass (Sorghum sudanense Piper.) are the supreme drought-tolerant grasses that are commonly grown in dry regions. Besides water, nitrogen (N) is a vital element limiting the growth, yield, and herbage quality of such grasses since it has key roles in physiological and biochemical functions in plants. Hence, this study aimed at assessing the performance of Buffel and Sudan grasses under nitrogen fertilization in Mandera County. This study comprised a field trial laid as a split plot in a randomized complete block design with grasses being assigned to the main plots, whereas N rates (0, 35, 70, 105, and 140 kg N ha−1) occupied the subplots. Data were collected on growth parameters (plant height, leaf length, number of leaves per plant, leaf width, stem girth, and tiller number), yield parameters (shoot weight, root weight, and aboveground biomass yield—DBY), and quality attributes (acid detergent fiber—ADF, crude protein—CP, and neutral detergent fiber—NDF). Across the seasons, plant height progressively increased with increasing N rates up to a maximum of 141 and 246 cm for Buffel grass and Sudan grass, respectively, which were associated with a 105 kg N ha−1 rate. Nonetheless, there was no noteworthy enhancement in plant height (142 and 246 cm) with an additional upsurge in N fertilizer rate to 140 kg N ha−1 relative to the one of 105 kg N ha−1. Regarding the leaf length, Sudan grass had longer and wider leaves at all treatment levels than the Buffel grass. Plant height, leaf length, width, and the number of leaves per plant increased with increasing N level up to the rate of 140 kg N ha−1, though this was not statistically different from the rate of 105 kg N ha−1 for both kinds of grass. The results revealed that Sudan grass contained higher crude protein than Buffel grass at all levels of treatments (10.33 and 8.80% at the rate of 105 kg N ha−1, respectively). More so, crude protein content was found to be higher in plots where N application was performed than in the control plots. There were great associations between the dependent variables (DBY, ADF, NDF, and CP) and independent variables (plant height, leaf length, No. of leaves, leaf width, stem girth, and No. of tillers), with the coefficient of regression ranging from 0.56 to 0.96 for Buffel grass and 0.59 to 0.96 for Sudan grass. Findings from this study indicate that for optimal growth, yield, and nutrient content benefits, Buffel and Sudan grasses ought to be grown using nitrogen fertilizer at a 105 kg N ha−1 rate.
