Abstract

Hydroponic systems offer a promising solution for sustainable green fodder production, but selecting appropriate nutrient media is crucial for optimizing plant growth and productivity. However, there is a lack of comprehensive studies evaluating the performance of different hydroponic nutrient media on green fodder crops, particularly in the context of nutrient film technique (NFT) systems. This study aimed to assess the performance of three hydroponic nutrient media (Cooper, Hoagland & Arnon, and ACI Vitamix) on the growth and yield of three hydroponic green fodder crops (maize, wheat, and Sudan grass) in NFT systems.  Hydroponic experiments were conducted using NFT systems to evaluate the performance of the selected hydroponic nutrient media and green fodder crops. Parameters such as fodder length, root length, and fodder yield were measured at 14 days after sowing (DAS). Fluctuations in pH, TDS, and EC were monitored at regular intervals throughout the growth period. The results demonstrated significant variations in growth parameters among the different hydroponic nutrient media treatments. Maize fodder exhibited superior performance in terms of fodder length, root length, and fodder yield when grown in the Cooper nutrient media. Fluctuations in pH, TDS, and EC levels were observed, reflecting variations in nutrient concentrations and uptake dynamics. Maize fodder showed the highest performance in Cooper nutrient media, followed by wheat and Sudan grass. Fluctuations in pH, TDS, and EC were observed, indicating variations in nutrient availability and solution stability over the growth period. Based on the findings, it is recommended to prioritize the use of cooper nutrient media for maize fodder production in hydroponic NFT systems to optimize growth and yield. Additionally, close monitoring of nutrient levels and pH stability is recommended to ensure optimal nutrient management and system performance in hydroponic green fodder production.
