Identification of suitable media based on hydroponic culture for production Zucchini squash

Abstract

An experiment was conducted to identify the hydroponic culture based suitable media for the production of Zucchini Squash in the Biochemistry Laboratory, Patuakhali Science and Technology University, Dumki, Patuakhali, Bangladesh during 2014. Zucchini plant (Cucurbita pepo L.) were grown in closed soilless systems to determine the effect of four different hydroponics media on plant growth, yield and nutrient contents (fruit moisture content, ascorbic acid content on fruit, fruit protein content, protein content in leaves). Three types of substrates (coconut husk, jute, cotton) along with Hoagland solution were used in this experiment. Result revealed that media using Jute fiber showed significant effect on plant growth and nutritional values than the other media (media of cotton with Hoagland solution, coconut husk with Hoagland solution and only Hoagland solution). The plant grown using jute media showed the highest plant height (60.33 cm), number of leaves (17.33), yield (1.5 kg plant -1 ), fruit moisture content (97.33%), Ascorbic acid content in fruit (28.73 mg 100g -1 ), protein percentage in fruit (1.406%) and percentage (1.326%) in leaves than the other media. Therefore, with the controlled nutrient supply, less expense, less labor, no use of pesticides or fertilizer with controlled environment the use of jute fiber as a substrate with Hoagland solution can be an effective one.

Integration of algae treatment with hydroponic crop waste to reduce impact of nutrient waste streams

“…Extracting peat for compost is controversial due to the ability for peatlands to act as a long‐term natural sink and store of carbon. Recycled materials such as coconut husk, tree bark, and cotton (e.g., Arancon et al, 2014; Suvo et al, 2017) have all been used with success in CEA systems and may improve the circular economy of waste products from other industries. Improving sustainability of CEA systems in future may involve using waste rooting materials for further food production.…”

Aplicativo web para el monitoreo y control de variables físicas en cultivo hidropónico de espinaca

“…Muchos sistemas ofrecen la posibilidad de monitorear y/o controlar variables en cultivos hidropónicos, pero estos requieren del manejo local (Suvo et al, 2016) en PC dentro del cultivo (Walters, 2015) o de aplicativos móviles, y otros funcionan mediante Bluetooth® (Chiara et al, 2016) o algunos Iot (Rojas et al, 2019); (Briceño y Cubides, 2020); (Bhattacharyya et al, 2021). Dichos sistemas, necesitan de la presencia de un supervisor en la zona del cultivo o en sus alrededores; o en su defecto, requieren de la instalación aplicaciones en sus dispositivos.…”

Aerated chicken, cow, and turkey manure extracts differentially affect lettuce and kale yield in hydroponics

“…In addition, hydroponic systems often use less water and have higher water efficiency, as nutrient solutions are not lost to ground infiltration (Surendran et al 2016). As such, the productivity per unit area of a hydroponic system is higher than that of field-grown agriculture, and growing crops in controlled environments allow for the cultivation of plants with higher and more uniform nutritional values (Surendran et al 2016;Suvo et al 2017).…”
