Grain legumes in tropical areas are of great importance as a food source, especially in rural communities. Little is known about their adaptability and behavior in non-alluvial soils of the Peruvian Amazon. Our objective was to assess the agronomic behavior of cowpea varieties in non-alluvial soils. The experiment was performed in completely randomized design with four treatments and four repetitions. Each experimental unit consisted of five rows of 6m length by 0.5m between plants and 1m between rows. The variables evaluated were: plant height (cm), number of pods, pod length (cm), number of graind per pod, grain length (mm), grain width (mm), and weight of 100 seeds (g). An analysis of variance and Tukey’ test at 5% probability were used to determine significant differences between treatments. Results showed significant differences between varieties according to the evaluated variables. The red cowpea presented significant differrences for the agronomic characteristics in plant height (62.83cm), grain length (8.68mm), and weight of 100 seeds (16.87g) in relation to the other varieties. The Chiclayo Olho Preto variety stood out only in grain width (5.46mm), and the Chiclayo Vermelho in pod length (19.58cm). The red cowpea has the potential to be cultivated preliminarily in larger-scale areas in the Yurimaguas district
Comportamiento agronómico de cuatro variedades de caupí (Vigna unguiculata) establecidas en la EEA San Ramón - Yurimaguas
(Instituto Nacional de Innovación Agraria, 2021-06-14) Angulo Villacorta, Carlos Darwin
Las leguminosas de grano son consideradas como la segunda fuente vegetal más valiosa para la nutrición humana (Naiker et al., 2019). El caupí (Vigna unguiculata L. Walp) es una leguminosa herbácea anual que pertenece a la familia Fabaceae (Wani et al.,2016). Se estima aproximadamente 14 millones de hectáreas son cultivas en todo el mundo (López et al., 2001). Se compartieron los resultados que se han venido obteniendo en el trabajo de investigación denominado “Comportamiento agronómico de cuatro variedades de caupí (Vigna unguiculata) establecidas en la EEA San Ramón – Yurimaguas”. Estos resultados se dan a conocer de acuerdo a las charlas que se van realizando en el marco del proyecto PROAGROBIO.
Manual técnico de buenas prácticas agrícolas para la producción de frijol caupí en áreas de tierra firme
(Instituto Nacional de Innovación Agraria, 2022-11) Campos Cedano, Johnny Carlos; Angulo Villacorta, Carlos Darwin
Este manual técnico reúne información del cultivo de frijol caupí, destacando su importancia económica, agroecología, manejo agronómico, cosecha, secado y almacenamiento; lo que permitirá conocer las buenas prácticas agrícolas para la producción de este cultivo en áreas de tierra firme y promover su uso potencial en beneficio de los sectores agroalimentarios. El Ministerio de Desarrollo Agrario y Riego (MIDAGRI), a través del Instituto Nacional de Innovación Agraria (INIA), tiene la misión de conservar los recursos genéticos de uso agrario y fomentar su puesta en valor y producción, además de ser responsable del Banco de Germoplasma más importante del Perú en materia de agrobiodiversidad; de modo que custodia 100 accesiones de frijol caupí (Vigna unguiculata (L.) Walp). El presente documento se ha elaborado en base a los resultados obtenidos de diversos trabajos de conservación y caracterización agromorfológica de frijol caupí desarrollados en la Estación Experimental Agraria San Ramón – Yurimaguas, a lo largo de dos años.
Physiological characterization and bioactive compounds of promising accessions of cowpea (Vigna unguiculata L. Walp) in the Peruvian Amazon

Cowpea production in the Peruvian Amazon is increasing due to its ability to adapt to diverse environments, its contribution to soil conservation, and its versatility of uses. This crop is particularly valuable in human nutrition due to its high nutritional quality and nutraceutical properties of its bioactive compounds. The aim of the study was to evaluate the physiology of cowpea plants in accessions PER1005854, PER1005851, and PER12645, under the influence of rice husk mulch, screw tree litter, and oil palm fiber, as well as to determine the bioactive compounds present in the grains. This study aims to promote sustainable cowpea production, expose the nutritional aspects of the grains, and foster their consumption both locally and nationally. The experiment was conducted from November 2022 to March 2023, in Yurimaguas, Loreto, Peru. The application of organic mulches demonstrates a significantly positive impact on the growth of cowpea accessions during their vegetative phase. This effect is possibly attributed to increased water availability, as the mulch reduces soil evaporation. In particular, cowpea accessions PER12645 and PER1005851 exhibit desirable physiological characteristics for grain production, with short cycles of 71 days and higher yields of 1141 and 1125 kg/ha respectively. In contrast, accession PER1005854 is distinguished by its higher biomass production, reaching a value of 14497 kg/ha, a relevant trait for foliage production and its contribution to soil conservation. The bioactive compounds, such as proteins, lipids, and carbohydrates, present in the accessions PER1005854, PER1005851, and PER12645, are similar to those found in other legumes. However, the antioxidant activity of dark tegument cowpeas proved to be superior, particularly highlighted in accession PER12645 (black tegument) with 26.3 μmolTG/g, and in accession PER1005854 (dark red tegument) with 19.5 μmolTG/g. This characteristic is particularly important for consumption, as it is related to the ability to combat oxidative stress in the human body.
