Water Spinach (Ipomoea reptans Poir) Hydroponic Kratky System at Various Levels of PbSO4 Contamination
2024Nyayu Khodijah, Ratna Santi, Riwan Kusmiadi, Ivan Rismunandar · Jurnal Agritech · Global
This research investigated the effect of nutrient type and lead (Pb) absorption on water spinach growth in a Kratky hydroponic system over 30 days. Plants were exposed to PbSO4 concentrations of 50, 100, 150, and 200 mg/L, with standard hydroponic (ABmix) and alternative nutrients. The study found that nutrient type significantly affected most growth parameters, with ABmix performing better than alternative nutrients. Crucially, no growth disturbance was observed due to PbSO4 contamination, and the combination of Pb concentration and nutrient type did not significantly affect growth or production, except for the number of leaves.

2023Simon Marvin, Lauren Rickards, Jonathan Rutherford · Urban Studies · Global
This paper critically examines urban controlled environment agriculture (CEA), reconceptualizing it as an emergent urban infrastructure for artificial, highly productive microclimates. It argues that CEA attempts to secure food production through three spatial-temporal fixes: enclosing food production indoors, moving it closer to cities, and integrating it into city buildings, thereby extending existing agricultural logics. The paper identifies future research challenges for urban studies regarding CEA.

Digital agricultureEconomicsSoilless urban gardening as a post covid-19 food security salvage technology: A study on the physiognomic response of lettuce to hydroponics in Uganda
2023Margaret S. Gumisiriza, Patrick A. Ndakidemi, Zainah Nampijja, Ernest R. Mbega · Scientific African · Uganda
In Uganda, this study assessed vegetable performance using a non-greenhouse hydroponic system to investigate its potential as a sustainable urban farming technology for enhancing food security. Leafy lettuce (red and green) was grown using non-circulating hydroponics, with soil-based cultivation as a control, and six parameters—plant height, root length, number of leaves, lettuce weight, moisture content, and dry matter—were measured 20 and 40 days after transplanting. Significant differences (P < 0.05) were found between soil and hydroponic cultivation for dry matter content, fresh weight, and root length, but based on the number of leaves, hydroponics showed potential to perform as equally well as conventional farming.
