“…Estas propiedades son indispensables para el movimiento de los nutrientes y la disponibilidad de estos, esta última va a depender de los cambios en el pH en la zona de las raíces durante el ciclo del cultivo, lo que va a permitir mayor o menor disponibilidad de elementos minerales, por lo cual se debe tener en cuenta en los programas de fertilización el monitoreo de las diferentes variables químicas del sustrato (Sonneveld & Voogt, 2009).…”

“…As revealed by leaf tissue analysis, Na + concentration was significantly higher in plants grown on coir substrate compared to perlite:coir, pumice, and perlite substrate treatments (Table 4). Coir is an organic substrate with high ion exchange capacity due to the presence of polysaccharides in the organic matter of the growing medium [70]. Thus, the main cations adsorbed to the fixed negative charge of coir are mainly K + and Na + , which probably explains the increased uptake of Na + from the plants compared to the inorganic growing media of perlite and pumice.…”

Table grape production in soilless cultivation under a controlled environment is a promising solution that addresses many of the challenges of grapevine cultivation, such as factors affecting the quantity and quality of table grape production, cultivation cost, pest management, soil degradation, soil-borne diseases, and adaptation to climate change. However, due to limited knowledge, investigation of many factors is required to effectively implement soilless cultivation, among which are the substrate’s physical-hydraulic properties and suitability for grape production. In this context, we investigate the impact of the properties of organic (coir dust) and mineral (perlite, pumice) substrates and their blend (perlite:coir) on grapevine growth and grape physicochemical characteristics of Sugraone (Superior Seedless) and Prime cultivars. Perlite substrate was the best in qualitative and quantitative production characteristics, whereas pumice substrate proved unsuitable for soilless vine cultivation. Coir and perlite:coir substrates, due to their increased ability to retain moisture, improved plant nutrition and grape quality but delayed ripening. For effective soilless cultivation of grapevines and table grape production, substrates must have the ability to maintain sufficient but not excessive moisture, suitable for supporting physiological processes and plant nutrition, resulting in smooth growth and production.

This study was conducted to evaluate the effect of three types of nutrient solutions on the development, performance, quality and cost of chonto tomato (Solanum lycopersicum L.) under semi-controlled conditions. The assessment was conducted in the farm Tesorito, Manizales, Colombia. An experimental design was established in randomized complete blocks (RCB), with 3 treatments, 4 replicates per treatment and 10 effective plants per replicate. The variables were: height of the first cluster, production per plant, yield t ha-1 and qualities of the fruit. The economic variables were production costs, cost-benefit ratio (C/BR), rate of return (IRR) and net present value (NPV). In general, production per plant was greater than 4.7 kg plant-1 and the average yield was 92 t ha-1. The use of conventional fertilization (tt2) generated increased production of premium quality fruit with a value of 37.11 t ha-1, demonstrating that conventional soil fertilization implemented in this culture under semi-controlled conditions in the company of drip irrigation system in the root zone improve outcomes of productive variables, increasing profitability and competitiveness with a net profit of USD$ $ 25203.68 ha-1, with average selling price of USD$ 0.45 per kilogram and a unit production margin of USD$ 0.21 per kilogram, making this technology attractive and economically viable.
