Abstract
One of the main concerns related to closed systems is the potential spread of root pathogens. With the recirculation of nutrient solutions. Ozone treatment was tested for the efficacy against plant pathogen (Pythium), growth and yield of cucumber crop grown in hydroponic closed system during summer season (June-August) 2022. Two nutrient solution feeding tanks were used one with ozone treatment and other without ozone treatment in randomized complete design (RCD) with four replication. The results showed significant (p < 0.05) differences were observed between the treatments in diseases infections with pythium diseases. No significant (p < 0.05) differences were detected in chlorophyll content, as SPAD values and yield between the two treatment of cucumber statistically. Ozone treated plants produced more yield 4.0 ton/gh.
期刊介绍：
The Journal of Agricultural Science publishes papers concerned with the advance of agriculture and the use of land resources throughout the world. It publishes original scientific work related to strategic and applied studies in all aspects of agricultural science and exploited species, as well as reviews of scientific topics of current agricultural relevance. Specific topics of interest include (but are not confined to): all aspects of crop and animal physiology, modelling of crop and animal systems, the scientific underpinning of agronomy and husbandry, animal welfare and behaviour, soil science, plant and animal product quality, plant and animal nutrition, engineering solutions, decision support systems, land use, environmental impacts of agriculture and forestry, impacts of climate change, rural biodiversity, experimental design and statistical analysis, and the application of new analytical and study methods (including genetic diversity and molecular biology approaches). The journal also publishes book reviews and letters. Occasional themed issues are published which have recently included centenary reviews, wheat papers and modelling animal systems.
