The article “Response of Hydroponic Tomato to Daily Applications of Aqueous Ozone via Drip Irrigation (Graham, Thomas, et al.)” explores the impact of aqueous ozone on hydroponic tomato production. The study aimed to determine if aqueous ozone impacts tomato productivity when applied directly to a mineral wool growth substrate via drip irrigation. The research found that at the highest aqueous ozone treatment level (3.0 mg L−1), there were significant increases in leaf area, shoot dry matter, and stem thickness in hydroponic tomato plants. However, all treatments had no differences regarding net CO2 assimilation rate, stomatal conductance, internal leaf CO2 concentration, chlorophyll content index, and fruit production. Additionally, both ozone treatments resulted in a reduction in algae prevalence on the substrate surface.
The study investigated the impact of aqueous ozone on hydroponic tomato production, specifically focusing on leaf area development, shoot dry matter accumulation, and other growth parameters. The results indicated that the highest aqueous ozone treatment level (3.0 mg L−1) significantly increased leaf area and shoot dry matter accumulation. However, the stimulatory effect on shoot dry matter was only significant during the study’s first phase and was not sustained by the final harvest period. The study also found that there were no sustained significant differences in net CO2 assimilation rate, stomatal conductance, or internal leaf CO2 concentration in any of the ozone treatments applied. Additionally, the research revealed a reduction in algae prevalence on the mineral wool substrate with both ozone treatments. The study also discussed dissolved oxygen and aqueous ozone persistence and the potential benefits of using ozone in greenhouse irrigation management. The results suggest that aqueous ozone can positively impact certain growth parameters in hydroponic tomato production, particularly at higher concentrations.
In conclusion, the study provides valuable insights into the impact of aqueous ozone on hydroponic tomato production and suggests that retaining residual ozone in the irrigation solution can benefit plant productivity and irrigation system maintenance.
Makala <unk>Jibu la Hydroponic Tomato kwa Matumizi ya Kila Siku ya Ozoni ya Maji kupitia Umwagiliaji wa Drip (Graham, Thomas, et al. )<unk> inachunguza athari za ozoni ya maji kwenye uzalishaji wa nyanya ya hydroponic. Utafiti huo ulilenga kuamua ikiwa ozoni ya maji inaathiri uzalishaji wa nyanya wakati unatumiwa moja kwa moja kwenye substrate ya ukuaji wa sufu ya madini kupitia umwagiliaji wa matone. Utafiti huo uligundua kuwa katika kiwango cha juu cha matibabu ya ozoni ya maji (mg 0.0 L-1) kulikuwa na ongezeko kubwa la eneo la majani, suala la kupasua kavu, na unene wa shina katika mimea ya nyanya ya hydroponic. Hata hivyo, matibabu yote hayakuwa na tofauti kuhusu kiwango cha usawa wa CO2, conductivity ya stomata, mkusanyiko wa ndani wa jani la CO2, index ya maudhui ya chlorophyll, na uzalishaji wa matunda. Kwa kuongezea, matibabu yote mawili ya ozoni yalisababisha kupunguzwa kwa kuenea kwa mwani kwenye uso wa substrate. Utafiti huo ulichunguza athari za ozoni ya maji kwenye uzalishaji wa nyanya ya hydroponic, haswa kwa kuzingatia maendeleo ya eneo la majani, mkusanyiko wa nyenzo kavu, na vigezo vingine vya ukuaji. Matokeo ya utafiti huo yalithibitisha kuwa kiwango cha juu cha matibabu ya ozoni ya maji (mg ya 0.0 L-1) iliongeza kwa kiasi kikubwa eneo la majani na kuongeza mkusanyiko wa vitu kavu. Hata hivyo, athari ya kuchochea juu ya shina kavu ilikuwa tu muhimu wakati wa awamu ya kwanza ya utafiti na hakuwa na kudumu na kipindi cha mwisho cha mavuno. Utafiti huo pia uligundua kuwa hakukuwa na tofauti kubwa katika kiwango cha uingizaji wa CO2 wa jumla, conductivity ya stomata, au mkusanyiko wa CO2 ya ndani ya majani katika matibabu yoyote ya ozoni. Kwa kuongezea, utafiti ulifunua kupunguzwa kwa kuenea kwa mwani kwenye substrate ya sufu ya madini na matibabu yote mawili ya ozoni. Utafiti pia kujadiliwa dissolved oksijeni na aqueous ozone kudumu na faida ya uwezekano wa kutumia ozone katika usimamizi wa umwagiliaji chafu. Matokeo yanaonyesha kwamba ozoni ya maji inaweza kuathiri vyema vigezo fulani vya ukuaji katika uzalishaji wa nyanya ya hydroponic, haswa kwa mkusanyiko wa juu. Kwa kumalizia, utafiti huo hutoa ufahamu muhimu juu ya athari za ozoni ya maji kwenye uzalishaji wa nyanya ya hydroponic na unaonyesha kwamba kuhifadhi ozoni iliyobaki katika suluhisho la umwagiliaji inaweza kufaidika uzalishaji wa mmea na matengenezo ya mfumo wa umwagiliaji.
