Chloris Gayana

Nitrogen is the most important macronutrient for forage and food crop production. Currently, cultivable lands in Ethiopia undergo a deficiency of this element. Thus, this study was conducted to find an appropriate rate of nitrogen (N) fertilizer for the better agronomic performance of Chloris gayana Masaba. The experiment was carried out at Assosa Agricultural Research Center. The experiment was conducted using a randomized complete block design with three replications, and the treatments were five levels of nitrogen fertilizer (0, 23, 46, 69, and 92 kg N/ha). The collected data were analyzed using the general linear model procedure of SAS, and the least significance difference was used for mean separation. Plant height at forage harvesting, dry matter yield, leaf to stem ratio, leaf height, number of leaves per plant, number of tillers, and seed yield were significantly ( p < 0.001 ) influenced by the year of planting while nonsignificantly ( p > 0.05 ) by nitrogen fertilizer rate and interaction of planting year and fertilizer rate. The mean leaf to stem ratio was significantly ( p < 0.001 ) higher in 2017 and 2018 than in the 2019 planting year. However, forage dry matter yield was significantly ( p < 0.001 ) higher in 2019, followed by 2018 and 2017 planting years. Mean seed yield was significantly ( p < 0.001 ) different among the establishment years and the peak seed yield productivity attained during the third year of harvesting (1st = 2nd < 3rd year of harvesting). Generally, all measured agronomic traits were not significantly responsive to the different fertilizer rates, and in the economic point of view, 0 kg of N/ha is recommended.

SummaryResults are reported from experiments with nitrogen and potash fertilizers in irrigated Rhodes grass (Chloris gayana), into which annual winter legumes, e.g. berseem (Trifolium alexandrinum) and vetch (Vicia sativa) were overseeded. The experiments were carried out over a three year period on a sandy loam soil at Bet Dagan Experimental Farm, Israel. Ammonium sulphate, applied in equal split rates of up to 384 lb N per acre, linearly increased dry matter yields of Rhodes grass, and the increase of yield proportionally increased the uptake of K by harvest. The K content of the dry matter decreased with increasing nitrogen fertilization to 0·47 per cent which, however, was still found sufficient for maintaining maximum production of Rhodes grass. The yield of annual winter legumes decreased proportionally to the amount of nitrogen fertilizer applied during the summer. Acute potassium starvation was observed. An autumn application of potassium chloride restored dry matter production to normal levels. Availability of soil K, expressed in terms of energies of replacement [ΔF(− 1)], decreased proportionally to the amount of nitrogen fertilizer applied. When ΔF reached approximately 4,250 cal/mol, overseeded legumes were K-deficient, whereas Rhodes grass at that value was still able to extinct sufficient K from the soil for normal growth.

A field experiment was conducted during the 2016 and 2017 rainy seasons at Centre for Agriculture and Pastoral Research (CAPAR) of the Usmanu Danfodiyo University Sokoto, Nigeria to study the effect of nitrogen fertilizer and inter-row spacing on herbage yield and some yield parameters of Rhodes grass. A factorial combination of five fertilizer levels (0, 100, 120, 140 and 160 kgNha-1) and three inter row spacing (30, 50 and 70 cm) were used, making fifteen treatments combinations, which were laid out in a RCBD replicated four times. Determination of herbage dry matter yield at the end of 12 weeks post planting was carried out using a 0.25 m2 (0.5 m x 0.5 m) area metallic frame (Quadrat). The herbage was harvested at 5 cm above ground level using hand Sickle from the four plots for each treatment. The samples collected ware oven dried for the determination of dry matter yield, while determination of number of leaves and number of tillers per plant was done by counting the numbers of individual leave and tillers of each of the representative plant sample. The result revealed that, Application of 160 KgNha-1 generally produced higher (P < 0.05) dry matter yield, number of leaves and number of tillers compared to the rest of the treatment, There was no significant (P > 0.05) effect of inter row spacing in both 2016, 2017 and the years combined on herbage dry matter yield, however significant (P < 0.05) effect of spacing was observed in 2016, 2017 and the years combine on the numbers of leaves and numbers of tiller. Inter-row spacing of 70cm showed superiority among the treatments in the herbage yield compositions investigated compared to 50 and 30cm spacings.

Abstract Degradation of crop and grazing lands is a pervasive problem that negatively impacts agricultural productivity and livelihoods of crop-livestock farmers in the Blue Nile basin of Ethiopia. Area enclosure together with a cut and carry livestock feeding system is often advocated as an approach for the regeneration of degraded grazing lands. This paper reports the results of a two-year farmer participatory study conducted to assess the effects of infiltration trenches (ITs) and Chloris gayana Kunth (Rhodes grass; cultivar Masaba; tetraploid; C4 grass species) reseeding on restoration of degraded grazing lands. A split plot design was used with IT as the main plot and C. gayana reseeding as a sub-plot on 28 private grazing plots under enclosure. The results showed that IT alone increased soil moisture content and prolonged the growing period. IT and C. gayana reseeding together significantly (P ≤ 0.05) increased herbage dry matter yield and improved soil chemical properties. The highest mean herbage dry matter yield (21 Mg ha−1 per cut) was recorded for plots treated with IT and reseeded with C. gayana. The higher herbage dry matter yield was attributed to increased soil moisture and the resultant prolonged growing period induced by the trenches coupled with the ability of C. gayana to effectively utilize the retained water. The results suggest that an integrated land management approach involving enclosure, in-situ water conservation and C. gayana reseeding can rapidly increase biomass productivity on degraded grazing lands while also enhancing soil quality with concomitant livelihood benefits for farmers.

On farm adaptability test of different grass species was conducted on pastoral area of Keelewe peasant association in Dassench Woreda of South Omo Zone in 2016 under irrigated condition with the objective to identify high biomass yielding grass species. The field experiment was laid out in a Randomized Complete Block Design with four replicates per tested species. The tested grass species were Chloris gayana, Cenchrus ciliaris and Panicum colaratum. The result indicated that there was a significant difference (p>0.05) among the tested grass species. Panicum colaratum yields the highest (18.08 t/ha) than the Chloris gayana (15.21 t/ha) whereas, Cenchrus ciliaris had yielded the lowest dry matter yield (11.20t/ha) than Chloris gayana and Panicum colaratum. The Panicum colaratum was one with maximum dry matter yield being recommended for irrigated conditions in the study area. However, further testing is required on feeding value, dry matter yield under different fertilizer dose, stem height, leaf to stem ratio, irrigation requirements and chemical composition of tested grass species.Bang.

An experiment was conducted twice concurrently at Vom in Plateau State Nigeria in 2011 to evaluate the effects of three animal based organic fertilizers and three rates of application on the growth, seed and herbage yields of Rhodes grass (Chloris gayana var. Callide). This study involved three types (poultry, rabbit and sheep dung) of animal fertilizer and three rates (0, 25 and 50 t ha-1) of application in a 3 x 3 factorial arrangement fitted into randomized complete block design and replicated three times. Animal fertilizers significantly (p < 0.05) increased growth, seed, fresh herbage and dry matter yields of Rhodes grass. Generally, fertilizers from poultry and rabbit were similar and better (p < 0.05) than that of sheep in the enhancement of the measured variables. At 6 weeks after fertilizer application (WAF), fresh herbage yield was in the range of 14.6 – 48.3 t ha-1 whereas dry matter yield ranged from 4.7 – 13.9 t ha-1 while seed yield was 1.8 – 2.3 t ha-1. At 12 WAF, rabbit fertilizer produced significantly higher values than sheep fertilizer by 21.2 % for sward height, 70.1 % for fresh herbage yield and 61.4 % for dry matter yield. The correlation coefficients among the measured variables were positive and highly significant. The highest correlation recorded (0.937**) was between fresh herbage and dry matter yields. The study indicated that application of either rabbit or poultry fertilizer can suitably enhance Rhodes grass growth for higher herbage and seed yields. The study also showed that 25 and 50 t ha-1 of animal fertilizers on Rhodes grass yielded similar results. With adequate fertilizer application, Rhodes grass can produce sufficient herbage to meet the nutritional requirement of several ruminant livestock. It is not economical to apply more than 25 t ha-1 of animal fertilizers to Rhodes grass if they contain more than 1.21 % of nitrogen.
