“…We observed the opposite pattern in regions of lower canopy height, with less light limitation compared to tall canopies; under such conditions, forage peanut grows parallel to the ground and colonises the entire uncovered soil space in a few weeks (Chozin et al 2018). As a result, there is an increase in the density of stolons, reflected in greater legume mass and legume predominance in the canopy LAI (Tamele et al 2018).…”

Context Understanding ecology in grass–legume pastures can help support strategies aimed at maintaining canopy stability in terms of botanical composition. Aims This 2-year study evaluated spatial variability, focusing on plant structural characteristics in a Marandu palisadegrass [Urochloa brizantha (Hochst. Ex A. Rich.) R.D. Webster cv. Marandu]–forage peanut (Arachis pintoi Krapov. and W.C. Greg. cv. BRS Mandobi) mixed canopy under grazing in continuous stocking management. Methods The pasture was managed with canopy height of 20–25 cm. The experimental area had a permanent sample grid containing 50 pre-established and georeferenced plots. Principal component analysis was performed, and spatial dependence structure of the first principal component and structural variables were separately characterised by geostatistical analysis. Key results There was spatial dependence of the structural characteristics, with marked spatial heterogeneity in the distribution of all variables. Taller grass canopies caused competition for light between species, reducing legume contribution and inducing more erect forage peanut growth habit. Conversely, in areas with lower grass canopy height, forage peanut botanical composition increased to up to 70%, as it propagated more effectively by stoloniferous propagation. Conclusions The canopy structure spatial variability of a Marandu palisadegrass–forage peanut mixed pasture determines the overall average pasture grass/legume proportion. In regions with taller canopies, Marandu palisadegrass was favoured, while in areas with shorter canopy, forage peanut proportion was promoted. Satisfactory legume proportions can be reached in the canopy despite areas with reduced legume contribution. Implications Our findings using geostatistical techniques facilitate the development of useful and innovative tools allowing better comprehension for the management of mixed pastures.

“…Practically, A. pintoi has been reported as a promising green manure with multiple benefits comprising soil coverage and nitrogen fixation [20,21,24,25]. In addition, other studies have demonstrated that the growth and yield components of corn (Zea mays) and tomato (Solanum lycopersicum) were significantly enhanced using a living mulch of A. pintoi [51][52][53] that concurrently reduced weed growth in some tropical upland crops as well as improving soil fertility and erosion [53]. Moreover, plant-derived allelochemicals and their interactions of plants-weeds-soils-microorganisms may actively regulate and contribute to promoting crop yields [11,54].…”

Pinto peanut (Arachis pintoi Krapov. & W.C. Greg.) is an herbaceous perennial plant which belongs to the Leguminosae family. This plant is well known for its use as a cover crop, but little information is available on the allelopathic potential of this legume. Therefore, this study aimed to explore the allelopathic effects of A. pintoi under various screening conditions and to analyze its potential allelochemicals using gas chromatography–mass spectrometry (GC-MS). In laboratory bioassays, aqueous extracts of A. pintoi powder exerted the average inhibition of the growth of Echinochloa crus-galli (55.1%), Oryza sativa (77.1%), and Vigna radiata (60.1%), respectively, of which the root lengths of the tested plants were the most suppressed. In greenhouse experiments, E. crus-galli was inhibited by 63.4% at 200 g/m2 of A. pintoi dried powder application. In field trials, A. pintoi also significantly reduced the growth of E. crus-galli and natural weeds. By incorporating a dose of 200 g/m2, the average inhibition of E. crus-galli was 43.9%, the dry weight of natural paddy weeds was 43.1%, and rice yield was simultaneously increased by 35%. The growth inhibitions of weeds and tested plants were proportional to the doses of A. pintoi applied and varied with the tested plant species. Among three different solvent extracts (methanol, hexane, and ethyl acetate), the hexane extract exerted the highest suppression against the growth of E. crus-galli and L. sativa by IC50 against root and shoot growth = 4.08 and 8.4 mg/mL and 1.7 and 1.54 mg/mL, respectively, followed by ethyl acetate extract, while the least effective was methanol extract. From those extracts, a total of 35 substances were detected by GC-MS analyses, including 14 newly identified constituents, such as phenolic acids, stearic acid, palmitic acid, fatty acids, pyranones, and benzofurans, which may be responsible for the herbicidal effects of A. pintoi. This study suggests that A. pintoi may be used as a source of bioherbicide to minimize the dependency on harmful synthetic herbicides and enhance rice yield.

Expanding agricultural land by using sloping dry land can be detrimental to the environment due to soil erosion and degradation. However, cover crops can be one of the technologies applied to reduce these risks. Arachis pintoi is one of cover crops that can be used as bio mulch on agricultural land. The study aimed to evaluate the effect of A. pintoi bio mulch on soil nutrient contents and maize plant growth at different slopes. A nested randomized block design was used in the study. Two levels of land used as the main factor and the type of mulch consisting of five levels (without mulch with weeding, without mulch without weeding, silver-black plastic mulch, straw mulch, and A. pintoi bio mulch) were used as the second factor. The results showed that A. pintoi bio mulch significantly increased the P content of the soil and could potentially increase several other macronutrients, especially C-organic, N, and Ca. The use of A. pintoi bio mulch with a cover technique that was left to cover the entire soil surface suppressed the growth and yield of maize plants compared to the control treatment.
