“…Out of these nine ecotypes, Ecotype 9 had a lesser DM decreasing, showing its better adaptation to environment conditions prevailing in the testing area. This ecotype was reported by Adjolohoun et al (2012) as droughttolerant and therefore could be less affected by decreasing rainfall in the area and this could account for its low decrease in dry matter production. This ecotype may also be less demanding in fertility, which may explain the lower decrease in production over time.…”

“…The superior yield of Ecotype 4 at all harvest regimes may be a function of its better soil nutrients or water use (Pieterse et al, 1997). On the other hand, Ecotype 4 was reported by Adjolohoun et al (2012) to have more leaves than others. This intrinsic trait of this ecotype can allow it to have more surface area and therefore more photosynthesis activity due to more solar irradiance quantity which could be intercepted.…”

“…Under the same environmental and growing conditions, concentration in P forage of Ecotype 7 was more than 3-fold that of Ecotype 2 showing the possibility of choosing P. maximum ecotype that could have an important contribution for herbivorous P diet for this region. On the other hand, the lowest P content of Ecotype 2 for animal production could have an important consequence for livestock nutrition by the fact that this ecotype is one of the most available in the area (Coastal region of West Africa) (Adjolohoun et al, 2012) and may be the only one available species sometimes. K concentrations of tested forages were largely above the critical values for deficiency suggested for grazing ruminants and summarized by (NRC, 2000).…”

“…Most of these species concerned exotic plants such as Pennisetum purpureum, Brachiaria ruziziensis, Centrosema pubescens, Stylosanthes hamata and Aeschynomene histrix. Very few studies were conducted on autochthonous species such as P. maximum ecotypes which could have a potential for animal production (Adjolohoun et al, 2012). The aim of this study was to identify P. maximum ecotypes and cutting regimes which could both maximize forage production and nutritive values on low fertility soils in order to provide recommendations on ecotypes and cuttings management to smallholder farmers.…”

The grassland resource could be better managed if the effect of different defoliation regimes on the amount of the dry matter and nutritive value was known. Consequently, 9 ecotypes of Panicum maximum were evaluated in central region of Benin with an average 1100 mm annual rainfall during 3 years for ley pasture without any fertiliser input. Three cutting regimes (3-10-3, 5-6-5 and 6-4-6-week) were tested for dry matter production (DM), crude protein (CP) content, CP production and mineral (Ca, Mg, P, K, Na, Zn, Mn, Cu and Co) contents. Significant differences were observed between ecotypes (p<0.001), cutting regimes (p<0.001) and years (p<0.001) for DM and CP production. Ecotype and cutting regime influenced significantly CP content (p<0.05) but year had no influence. Forage harvested from 3-10-3-week regime produced significantly (p<0.05) more DM (4742 kg DMha -1 ) than 5-6-5-week (3635 kg DMha -1 ) or 6-4-6-week cutting regime (3789 kg DMha -1 ). But the reverse effect was observed for CP content as 3-10-3-week regime (5.68 gkg -1 DM) had significantly (p<0.05) lower CP than those of 5-6-5week (8.55 gkg -1 DM) or 6-4-6-week cutting regimes (7.15 gkg -1 DM). Mineral concentrations varied between ecotypes but not by cutting regimes and years. Three ecotypes (n° 1, 4 and 5) consistently outproduced than others and can be harvested through 5-6-5-week cutting regime. P, Na, Zn and Cu deficiencies were the most common detected in the cropped forages.

Background: Adaptability and forage productivity of Panicum phragmitoïdes in the humid region of Côte d’Ivoire were evaluated compared to Panicum maximum cv C1 from October 2018 to April 2019. Methods: Three accessions of P. phragmitoïdes and P. maximum cv C1 were transplanted by cuttings with three replicates in a randomized complete blocks design to evaluate adaptability parameters and forage yield. Result: The average number of tallies per tuft of P. phragmitoïdes ranged from 15.83±2.24 to 19.17±7.39 versus 33.67±5.10 tallies for P. maximum cv C1. Accessions of P. phragmitoïdes ranged in height from 146.33±9.49 to 151.42±15.88 cm and were higher than P. maximum cv C1 which was 119.50±20.67 cm. The forage productivity of P. phragmitoïdes and P. maximum cv C1. were identical and ranged from 4.84±1.07 to 8.20±3.72 t DM/ha/year. P. phragmitoïdes seems to adapt well in the humid region of Côte d’Ivoire.

This study proposes to evaluate the influence of the spacing row and NPK 15-15-15 fertilizer and goat manure on Panicum maximum seed production and fodder nutritive value harvested in south Benin on ferralitic soil from 2015 to 2017. The experiment was a factorial design comprising all combinations of 4 row spacings (20, 40, 60 and 80 cm) and 6 fertilizers: six levels of fertilizer: (F0) No goat manure (Control) (F1), 100 kg NPK 15-15-15, (F2) 20 t/ha goat manure, (F3) 15 t/ha goat manure, (F4) 10t/ha goat manure + 33kg NPK 15-15-15 and (F5) 5 tons + 66 Kg NPK/ha. Four replications were used in the experiment. The results showed that wider row spacing (60 cm) enhanced seed production in this experiment. Number of total tillers/tussock, fertile tillers/tussocks and spike length were significantly greater under the widest rows spacing (60 cm and 80 cm). The best seed yield got with row spacing 60 cm (392.1 kg.ha-1) and 45.5% of caryopses germinate after six months of storage against 14.5% for spikelet. Seed yield and its attributes increased significantly with NPK combined to goat manures (F4).
