“…The concentrations of Na + (125–277 mg L –1 ) and Cl – (75–132 mg L –1 ) in treated PPW, although below the 2.34 g L –1 NaCl recommended limit for hydroponic nutrient solution, could induce salt stress in lettuce. Adhikari et al reported a 32% reduction in fresh mass of lettuce with 50 mM NaCl. Increasing salt content can create osmotic stress, interfere with the uptake of K + , , and reduce leaf protein content .…”

Poultry processing wastewater (PPW) is a nutrient-rich effluent with the potential for reuse in crop irrigation. This study investigated transforming PPW into a hydroponic nutrient solution using a pilot scale “poultryponics” system operated continuously for 222 days. The system treated ∼57 L d–1 of real PPW and consisted of bioreactors (inoculated with a consortium of microalgae and nitrifying bacteria), clarifiers, membrane filters, a UV disinfection unit, and a deep-water hydroponic system. The system was evaluated in terms of nitrogen transformation, organic removal efficiency, and pathogen levels. Although soluble organic removal efficiencies (sCOD) were high (>80%) in all bioreactors, nitrification was limited due to high organic loading (350–800 mg sCOD L–1), relatively short retention time (24 h), and low dissolved oxygen levels (<3.5 mg O2 L–1). Grow beds showed significant nitrification, indicating the importance of upstream organic removal. CO2 supplementation (0.5% v/v) in bioreactors did not promote nitrification in the bioreactors but was beneficial for nitrification in grow beds due to pH-modulating effects. Microbiological analyses showed no Salmonella detection in bioreactors and substantial reductions in total coliform (∼40%) and aerobic plate counts (∼30%) after UV treatment. These findings demonstrate the sustainable and safe reuse of nutrient-rich industrial effluents in agriculture.

Increased rice productivity can be achieved by producing high-yielding black rice seeds. One of the productions of superior seeds is by mutation induction using gamma-ray irradiation. Black rice has a useful content and will be produced when the plant grows in drought stress. This research aims to study the growth and physiological characteristics of black rice induced by gamma rays of 100 gray and 200 gray, as well as know the effect of drought stress on proline content, to obtain superior black rice seeds. The design was researched in the form of an experiment in the field without using a repeat sample. Black rice was planted as a screen house in Jati Village, Karanganyar. The treatment used 24 plant genotypes, namely, 10 genotypes of 100 gamma-ray irradiation and 2 control genotypes, as well as 10 genotypes of 200 gamma-ray irradiation and 2 genotypes of control. Physiological observation variables were plant height, plant dry weight, root dry weight, proline content, and leaf temperature. The results of the research on plant height growth with gamma ray irradiation resulted in shorter plant postures. Leaf temperature and proline content in plants treated with irradiation and drought stress had higher values than in control plants. M4-By-C and M4-Bt-C lines are prospective to be released as new high-yielding varieties because these lines have short stature and high proline content.
