This study investigated the effect of five nitrogen levels (80-160 ppm) and two pot volumes (6 L, 8 L) on lettuce (cv. Robinson F1 hybrid) in Giza, Egypt, during autumn 2022 and 2023. Increasing substrate volume from 6 L to 8 L and nitrogen concentration from 80 ppm to 140 ppm increased vegetative growth and yield. The 8 L volume and 140 ppm nitrogen concentration yielded the highest results for vegetative growth, yield, and nutrient content. However, 6 L pot volume with 80 ppm nitrogen achieved the highest net profit despite lower fresh weight, by providing the lowest nitrogen use efficiency and natural resource consumption.

Stephen Leitheiser, Rubén Vezzoni · Frontiers in Sustainable Food Systems · Global

This paper presents a conceptualization of radical food democracy (RFD), linking diverse economies with diverse citizenship. Diverse economies scholarship, while valuable for theorizing alternative food networks (AFNs), has been criticized for essentializing the autonomy of alternative economic practices, risking the confusion of emancipatory social change with market-embedded products and the displacement of negative impacts. The paper argues that realizing RFD requires both experimenting with new economic practices that create food economies alternative to capital accumulation and cultivating new political subjects capable of universalizing these struggles.
