This study was conducted to evaluate the influences of composts applying at different times on the growth, nutrient accumulation and yield of chrysanthemum plant. The research was conducted at Vietnam National University of Agriculture in Vietnam in 2023. Two types of compost were C3 (compost was prepared from rice straw, cow manure and elephant grass) and C4 (compost was prepared from rice straw, cow manure and cabbage leaves). The application times were T1 (20 days before transplanting), T2 (10 days before transplanting) and T3 (1 day before transplanting). The parameters of the growth, nutrient contents, yield of chrysanthemum were evaluated. The results showed that the C3 and C4 composts had similar effects on the growth and yield of chrysanthemum. Earlier application of compost caused the significantly higher values of the growth and yield parameters in comparison with later application. T1 treatment gave the highest values of experimental indicators. The combination effects of compost types and application times on the growth and yield of chrysanthemum were significantly different when comparing among the treatments. Application of C3 or C4 composts at 20 days before transplanting was both good for chrysanthemum growth with the highest values of LAI (0.911 and 0.958 of C3 and C4 treatment at bud stage), dry weight (175.85 and 163.87 g plant-1 of C3 and C4 treatment in harvesting stage) and yield (18.64 and 18.16 quintal ha-1 of C3 and C4 treatment).

Effectiveness of electron beam irradiation was evaluated against Rhizoctonia solani, which is one of the most dangerous soil-borne pathogen, causing stem base and root rot of many horticultural plants. Treatment of in vitro cultures with 0.5 kGy significantly inhibited the pathogen's growth and the spread of necrosis on chrysanthemum leaf blades inoculated with the irradiated cultures. Application of e-beam irradiation for peat disinfection resulted in a two-fold decrease rot development in chrysanthemum stem at a dose of 5 kGy and complete inhibition at 10 kGy. For the elimination of R. solani from composted pine bark and its mixture with peat, irradiation of both substrates with 15 kGy was necessary.

Electron beam (EB) irradiation was tested against Botrytis cinerea, Pythium ultimum and Phytophthora citricola the most dangerous pathogens causing stem and root rot of seedlings, cuttings and older plants. In the laboratory trials cultures of 3 species were irradiated with doses 0 (control), 1.5, 3.0, 4.5 and 6.0 kGy whereas peat was treated with 10,15 and 25 kGy. P. citricola was the most sensitive species for irradiation. In greenhouse trials 15 kGy irradiation of peat protected chrysanthemum cuttings against B. cinerea and P. ultimum as well as rhododendron young plants against P. citricola. Irradiation of peat did not influence the growth and development of the tested plants.
