Thu, 18 Jan 2024 00:00:00 +0000 OJS 60 Edaphic macrofauna in the establishment of an agroforestry system in the High Andean region of Southern Colombia <p>Biological degradation of the soil due to inadequate agricultural practices that eliminate vegetative cover and, therefore, organic matter, reduces the biological communities that perform important ecological functions in the soil. The objective of the study was to evaluate some biological properties of the soil in an agroforestry system with <em>Morella pubescens</em> intercropped with <em>Smallanthus sonchifolius</em> and in a degraded pasture of <em>Cenchrus clandestinum</em>. The trial was conducted at the Botana Experimental Farm, Nariño, at 2,820 meters above sea level. Density, richness and Simpson and Shannon-Wiener diversity indices were determined. A Randomized Complete Block Design with three replications was used. The treatments corresponded to sowing distances of <em>S. sonchifolius.</em> T1: sown at 1x1m, T2: 0.8x0.8m, T3: 0.5x0.5m and the control T4 corresponded to degraded pasture of <em>C. clandestinum</em>. The tree component <em>M. pubescens</em> was established at 4x4m between seedlings and 9m between rows. Soil macrofauna sampling was carried out following the monolithic TSBF method, collecting at depths of (0-10, 10-20 and 20-30cm). A total density of 6,496i/m2 individuals was found. The highest value was obtained in T3 (3,168i/m2) represented by the taxonomic groups Diptera and Haplotaxida. Higher values of richness were observed in T1. The Shannon index was higher in T2 (0.66) while T1 (0.80) presented higher dominance in morphospecies. Density and richness were higher in the agroforestry arrangement than in the degraded <em>Cenchrus clandestinum</em> pasture. Treatments, depth and their interaction did not significantly affect morphospecies diversity.</p> Martin Alonso Muñoz-Rodriguez, Ana Carolina Santacruz-Ortiz Copyright (c) 2024 Revista de Ciencias Agrícolas Thu, 18 Jan 2024 00:00:00 +0000 Use of silicate amendments on Improvement of the quality and nutrition of the potato crop, variety 'Diacol Capiro' <p>Potato (<em>Solanum tuberosum</em> L.) is one of the most important agricultural products in cold-climate areas of the world. However, the soils intended for potato production in tropical zones such as Colombia have low availability of essential elements, such as phosphorus, calcium, magnesium, and beneficial elements such as silicon. The general objective was to evaluate the application of increasing doses of three silicate amendments on the dynamics of accumulation of phosphorus, calcium, magnesium, and silicon in leaf tissue and their influence on the quality and production of 'Diacol Capiro' potato tubers under the conditions of Soracá municipality, Boyacá-Colombia. Two production cycles were evaluated, with a completely randomized design and 10 treatments in each cycle. It was observed that the application of double calcium and magnesium silicate at a dose of 900 kg ha<sup>-1</sup> as a crop management practice resulted in an increase in the accumulation of macronutrients such as P, Ca, and Mg by 63.1, 32.4, and 51.1%, respectively, and a 100% increase in silicon accumulation as a beneficial element; this was reflected in a 46% increase in total yield, with a higher production of first-quality tubers and a significant increase in dry matter and specific gravity compared to the application of conventional fertilization sources. Therefore, silicate fertilizers are an important alternative to improve quality and production through a better dynamic of accumulation of essential and beneficial nutrients in potato-producing areas in Colombia.</p> David Fernando Torres-Hernandez, Elberth Hernando Pinzón-Sandoval, Helber Enrique Balaguera-López, Amanda Silva-Parra, Pedro Jose Almanza-Merchán Copyright (c) 2024 Revista de Ciencias Agrícolas Sun, 26 Jan 2014 00:00:00 +0000 Assessment of transitory crops in cocoa (Theobroma cacao L) agroforestry in Páez, Boyacá <p>Agroforestry systems incorporate several productive components per unit area to yield efficiency. However, considering the high degree of complexity inherent to interspecific plant-plant interactions, little is known about most of these systems' real productive potential and efficiency. In this context, it is important to analyze the interactions between the components to identify potential favorable associations. The objective of this research was to evaluate the performance of the transitory crops maize (<em>Zea mays</em> L) and cowpea (<em>Vigna unguiculata</em> L) in a family farming system under three agroforestry arrangements with cocoa in the municipality of Páez, Boyacá, Colombia. A split plot design was used, where the main plots corresponded to three shade forest species, which were associated with cocoa and the transient crops. The subplots corresponded to three planting systems: CS1cocoa+maize, CS2 coca+beans and CS3 cocoa+maize+beans. The effect on agronomic and productive traits of transitory crops (maize and beans) was evaluated, and an economic analysis was carried out. For beans, the effect of the cropping system on yield (t. ha-1) stood out, while for maize, the statistical effect was given by the forest x cropping system interaction in most of the variables evaluated. Considering the interspecific interactions found under the influence of different forests, the use of Colombian mahogany as a companion species in these intercropping systems is suggested. The cost analysis revealed that the maize-bean association is more efficient in the equivalent use of land. Therefore, the data obtained reveal more efficient strategies for sustainable cocoa productivity in Colombia.</p> Lindays Alfonso-Alfonso, Laura Dayana Escobar-Pachajoa, Felipe Montealegre-Bustos, Fabricio Eulalio Carvalho, Dr, Albert Sneyder Carvajal-Rivera, Jairo Rojas-Molina Copyright (c) 2024 Revista de Ciencias Agrícolas Thu, 15 Feb 2024 00:00:00 +0000
