Smart Irrigation and Temperature Control for a Greenhouse System
Abinaya P,Swathika P International Journal of Computer ScienceNetwork S 2024 International journal of computer science and netw Vol.24 No.1
This project is designed with the aim to facilitate the farmer or gardener to engage in green house systems and to improve agricultural technology. In order to reduce continuous monitoring of the soil parameters, excess time consumption for the farmers and excessive usage of water, "Smart irrigation and temperature control for a greenhouse system" has been developed. There are two different ways to irrigate the land namely traditional irrigation methods and modern irrigation methods.

This study investigated the effects of silicon (Si) nutrition on hydroponically grown Zinnia elegans under salinity stress. In this study, six treatments, the control (basal nutrients without NaCl or Si), Si 50 (1.8 mM), Si 100 (3.6 mM), NaCl 50 (50 mM), Si 50 + NaCl 50 (1.8 mM Si; 50 mM NaCl), and Si 100 + NaCl 50 (Si-3.6 mM + NaCl-50 mM), were employed. After 15 days of treatment, growth parameters, biochemical measurements, and antioxidant enzyme activities were examined. Salinity stress significantly reduced plant growth, biomass, photosynthetic parameters, and pigments, and increased the electrolyte leakage potential (ELP), lipid peroxidation, and hydrogen peroxide level. Interestingly, with Si supplementation, Z. elegans recovered from salinity stress. Si enhanced growth and photosynthesis, and prevented the decomposition of photosynthetic pigments. Moreover, the addition of Si increased membrane integrity, thereby reducing the ELP and lipid peroxidation levels under salinity stress. Furthermore, Si modulated the activity of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and guaiacol peroxidase (GPX) in scavenging excess reactive oxygen species (ROS). Additionally, Si increased the macronutrient and micronutrient contents. Therefore, augmentation with Si provided salinity resistance and enhanced the growth of Z. elegans.

The objective of this study was to determine the effect of light quality on the growth, physiology, andantioxidant enzyme activity of two important domestic carnation (Dianthus caryophyllus) cultivars: ‘Green Beauty’and ‘Purple Beauty’. In vitro-grown shoot tip explants were cultured on the plant growth regulator (PGR)-freeMurashige and Skoog (MS) medium under a conventional cool white fluorescent lamp (control), blue light-emittingdiode (LED), or red LED. Growth traits, photosynthetic and biochemical parameters, activity of antioxidant enzymes,and nutrient content were measured after 8 weeks. Interestingly, the blue and red LED treatments resulted in asignificant increase in growth, photosynthetic parameters, and nutrient content in comparison to the conventional coolwhite florescent lamp treatment. In addition, red LED treatment increased the activities of antioxidant enzymes andelemental contents in both cultivars. Thus, incorporating blue or red LED treatments enhances the quality of ‘GreenBeauty’ and ‘Purple Beauty’ carnations propagated in vitro.
