Green pea (Pisum sativum L.) is a key crop for food security in communities of the Peruvian Andes; however, its productivity is constrained by low soil fertility and the high cost of nitrogen fertilisers. In this context, the effects of co-inoculation with Rhizobium leguminosarum bv. viciae (strain Ar-014) and Azospirillum brasilense (strain Az-007) on crop yield, crude protein content, and economic profitability were evaluated in comparison with conventional nitrogen fertilisation. The study was conducted at the Canaan Agrarian Experimental Station (Ayacucho, Peru; 2,750 m.a.s.l.) using a randomised complete block design with five treatments and four replicates: T01 (Rhizobium leguminosarum bv. viciae inoculation), T02 (Azospirillum brasilense inoculation), T03 (co-inoculation), T04 (mineral-N comparator, 82.5 kg N ha⁻¹), and T05 (uninoculated and unfertilised control). The results showed that T03 (co-inoculation) significantly outperformed nitrogen fertilisation (T04) (p < 0.01), achieving higher green pod yield (6.73 vs 5.63 t ha⁻¹), crude protein content (24.28 vs 23.67%), and economic profitability (262.75 vs 176.78%). Furthermore, T03 recorded the highest values for root length (21.73 cm), number of nodules per plant (20.27), and number of seeds per pod (6.07). Individual inoculation treatments (T01 and T02) also improved specific agronomic traits, such as aboveground biomass and number of pods per plant, respectively, although neither surpassed the performance of the co-inoculation treatment (T03). The Relative Yield Index (RYI_N) in the inoculated treatments was 16.85–19.49% higher than that observed under nitrogen fertilization. Overall, these results indicate that co-inoculation with R. leguminosarum b. viciae and A. brasilense (T03) represents a promising alternative to conventional nitrogen fertilization for green pea production under the evaluated high-Andean conditions, improving agronomic performance and economic profitability.

(Frontiers Media S.A., 2026-07-28) Yupa-Quichua, Máximo; Palomino Espinoza, Claudio Carlos; Condori Ataupillco, Leivi Tatiana; Alarcón Romani, Susan Milagros; Romero Chávez, Lorena Estefani; Bautista, Rolando; Solórzano Acosta, Richard Andi
The study was conducted at the Canaán Agrarian Experimental Station (INIA, Ayacucho, Peru) during the 2024–2025 growing season to compare the effects of three liquid bio-inputs—beneficial microorganisms (BM), effective microorganisms (EM), and biol—applied at 15 and 30% concentrations, on the yield and profitability of quinoa crops (Chenopodium quinoa Willd., cv. INIA 415–Pasankalla) fertilized with compost (6 t·ha⁻¹). Compost-only and unfertilised control treatments were also included. The experiment was arranged in a randomized complete block design with eight treatments and three replicates. The application of bio-inputs in combination with compost significantly increased aboveground dry biomass, with EM15% and BM15% showing the greatest increases (26.42 and 27.01%, respectively) compared with the control treatment. Regarding yield variables, BM30% achieved the highest values for panicle diameter (11.47 cm), panicle length (46.6 cm), grain weight per panicle (26.76 g), grain yield (2.06 t·ha⁻¹), and 1,000-seed weight (2.89 g). The lowest saponin content was recorded under BM30% (0.0001%), whereas BIOL15% and BIOL30% showed the highest values (14.25 and 14.27%, respectively). Economic analysis revealed that BM30% generated the highest net profit (S/11,047.89) and the greatest benefit-to-cost ratio (2.95). These results indicate that, under compost-based fertilization, the application of 30% BM outperformed EM and biol in enhancing both yield and economic profitability of quinoa cv. INIA 415–Pasankalla under inter-Andean valley conditions.

Local ecological knowledge for water management: a feasible solution through ecosystem services in high-Andean mountains
(Frontiers Media S.A., 2026-02-27) Flores Marquez, Ricardo; Puga Calderón, Rodrigo Julio; Condori Ataupillco, Leivi Tatiana; Madrigal Martínez, Santiago
Introduction: Mountain ecosystems are particularly sensitive to the impacts of climate change, which, in turn, affect the wellbeing of local populations. In this context, the sustainable use of ecosystem services is crucial to supporting the social and economic welfare of Andean communities in South America. The development of local ecological knowledge has facilitated both environmental adaptation and strengthened environmental awareness. Particularly, the qocha, an ancestral water-related agricultural technology, provides hydro-social value, and represents a local climate-change adaptation measure, however their ecosystem services valuation has not been integrally performed. Thus, we aimed to map and assess the perceived services associated with Yuyuchaqocha, a small reservoir managed by a high-Andean community characterized by pronounced economic poverty. Methods: The methodology included semi-structured interviews with key informants, participatory mapping, and field observation. The participatory process involved the community, municipal, and technical stakeholders operating within the study area. The economic valuation was done by contingent valuation, market prices, and travel cost methods. Results: The results revealed that local inhabitants recognized 10 ecosystem services (five provisioning services and five cultural services), primarily concentrated along its shores. The total local perceived value of these services was estimated at USD 10,104.97, benefiting the rural communities of Huanupampa and Totos. Among the cultural services, those related to community organization, species conservation, and the pagapu celebration had the highest economic values. Discussions: Disseminating the results at various organizational levels would foster the integration of the local worldview into management plans, contributing to their legitimacy and sustainability, and promoting the involvement of institutions engaged in the intervention of mountain water socio-ecosystems. In this regard, integrating local ecological knowledge with ecosystem services valuation can be replicated or adapted in other regions.
Water management in quinoa cultivation: quantification of the water footprint and climate projections in an inter-Andean valley
(Springer, 2026-04-07) Flores Galindo, Fredy; Condori Ataupillco, Leivi Tatiana; Flores Marquez, Ricardo; Alarcón Romani, Susan Milagros; Solórzano Acosta, Richard Andi
Efficient water management in agriculture is key to the sustainability of crops in inter-Andean valleys (IAV), where water availability is at risk due to climate change (CC). Quinoa, as a strategic crop in these ecosystems, requires a detailed analysis of its water use to optimize its production without compromising water resources. This study quantified the water footprint (WF) (green, blue and grey) of three quinoa varieties (INIA 415 Pasankalla, INIA 420-Negra Collana and INIA 441-Señor del Huerto) harvested in a sandy loam soil in an IAV of Peru. In addition, the trend of the WF in 12 agricultural seasons was evaluated, and future climate scenarios (SSP1-2.6, SSP3-7.0 and SSP5-8.5) were projected to estimate the impact of CC on the crop's water demand towards 2090–2100. The results showed significant differences in water-use efficiency among varieties. INIA 441-Señor del Huerto showed the highest water efficiency, with a 3.20 t ha⁻¹ yield and a low total WF, making it more sustainable under CC conditions. In contrast, INIA 420-Negra Collana had a higher water demand, making it less viable under water-stress scenarios. Climate projections indicate an increase in water demand for quinoa under scenarios of greater radiative forcing, which underscores the need to develop water management strategies. These findings highlight the importance of selecting more efficient varieties for water use and adopting sustainable practices to mitigate the effects of climate change on quinoa production at IAV.
