“…Nonetheless, there was no significant increase in yield with a further upsurge of N rate to 140 kg N ha −1 , an implication that the additional nitrogen was consumed luxuriously. These findings corroborate those of Kaplan et al [53], who reported that the green herbage yield of Sudan grass increased with an increase in nitrogen doses. The unfertilized plots were found to have a low forage yield for both Sudan and Buffel grasses.…”

“…Sudan grass produced more forage yield compared to Buffel grass, this is because of the greater tiller number and number of leaves produced by Sudan grass than Buffel grass [1,14]. Moreover, the higher forage yield observed in Sudan grass was also attributed to the fact that the dry matter in the shoot was more than that in Buffel, making Sudan grass a better feed for animals due to its higher quality [52,53]. It is also imperative to note that forage yield increased with treatment level, reaching optimum at N 4 (which had 105 kg N ha −1 ).…”

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.

“…Ethiopia has huge potential for forage production through small irrigation in approximately 31% of the country being extremely favorable for growing Desho [7]. Cultivation of improved forage varieties with better management practices and with supplementation of irrigation during the dry season is urgently needed, especially for dairy cattle [8].…”

The study was conducted to evaluate the agronomic performance, forage yield, and nutritive values of Desho grass varieties under supplementary irrigation at Dambi Dollo University experimental site, Western Ethiopia. Three Desho grass varieties (Areka /DZF#590, Kindu kosha-1/DZF #591, and Kulumsa /DZF #592) were arranged in randomized complete block design (RCBD) with three replications. The CROPWAT 8.0 model, local climate data, forage data, and soil data were used to determine Desho grass water requirements and irrigation schedules. The agronomic parameters, yield, chemical composition, and in vitro digestibility of the feed samples at standardization cut were determined following the standard procedures. The results showed significant differences (p

“…As the Ethiopian highlands are one of the most densely populated areas with livestock in east Africa (Benin et al, 2003), and an increase in livestock-based products is required, there is a need to study the agronomic performance of forage varieties and their responses to nutrients and water management (Worqlul et al, 2022). Therefore, this study aimed to investigate the performance and responses of selected fodder species under different irrigation and fertilizer application rates.…”

IntroductionThe increasing pressure on land and water resources, fueled by high population growth and climate change, has profound implications for crop yield and quality. While studies thrive for various crops, a notable research gap exists in understanding the responses of forage crops to irrigation and nutrient management in developing countries. This study aims to address this gap by assessing the impact of irrigation and fertilizer application on forage production in the Ethiopian sub-humid highlands.MethodsThe experiment focused on four forage varieties, namely Napier grass (Cenchrus purpureus) cultivars, ILRI-16791, ILRI-16819, ILRI-16803, and Guinea grass (Megathyrsus maximus) ILRI-144 cultivated in experimental plots. Three irrigation levels designated as IR60 (60% of total available soil water), IR80 (80%), and IR100 (100%) were applied, along with three fertilizer rates: organic manure at 30 t ha−1, and Urea-N at 100 kg ha−1 and 300 kg ha−1. Agronomic data including growth performance, forage dry matter yield, and nutritional quality were collected during two trial years.Results and discussionAmong the various irrigation treatments, IR80 demonstrated the most favorable balance between forage yield, WUE, net benefit, and LWP. In addition, the highest DMY, WUE, net benefit, and LWP were obtained for UREA at the rate of 300 kg ha−1 while the lowest DMY and WUE were observed for UREA at the rate of 100 kg ha−1. Significant variations were observed among the four forage varieties, with Napier grass ILRI-16791 having the highest DMY (9.8 tons ha−1), WUE (39 kg ha−1 mm−1), LWP (0.28 USD m−3 for local cows, and 1.04 USD m−3 for crossbred cows), and net benefit (783 USD ha−1). For all forages combined, a 40 and 20% decrease in irrigation increased water use efficiency by 17 and 9.4%, respectively. These results indicate that a moderate level of deficient irrigation such as IR80 could be a viable water management strategy for irrigated forage, especially in water-scarce areas. The conserved water saved from the deficit irrigation can thus be used to irrigate additional land, contributing to a more sustainable and efficient water usage approach.
