Soil management in integrated rose production system

Abstract

Integrated production systems have been used with various crops, and their use in floriculture is innovative. The effects of green fertilization in floriculture and the appropriate fertilization levels are still unknown. The aim was to identify the best dose of chemical fertilizer, with or without green fertilization, for integrated production of ‘Carola’ roses. The treatments consisted of 4 doses of the chemical fertilization recommended for rose bushes, (25%, 50%, 75%, and 100%), with or without green fertilization (calopo). Plants that were not treated with 100% (or complete) of chemical fertilization were supplemented monthly with Bokashi (16 g/plant, via the soil) and biofertilizer (5% via the leaves). The assessments were conducted 3 times per week for a year. The use of less chemical fertilizer did not affect rose production or quality, whereas the use of green fertilization did not provide a satisfactory outcome. The analyses, biometric, accumulation and nutrient content, and chemical characteristics of the soil, indicated that green fertilization with calopo was not beneficial. Moreover, with the exception of nitrogen and magnesium, there is the possibility of using 75% of the recommended chemical fertilization in rose bushes.

Ginger Extract and Fulvic Acid Foliar Applications as Novel Practical Approaches to Improve the Growth and Productivity of Damask Rose

“…In this context, rose plants maintained strong growth under adequate levels of nutrient elements [ 40 ]. Similarly, the growth attributes of rose plants were enhanced when the plants received proper levels of N, P, and K elements [ 67 , 68 ]. Furthermore, the P detected in GE is essential for root development promotion and, consequently, increased the water and nutrient absorption capability [ 69 ].…”

Response of Rose Growth and Flowering to NPK and Potassium Silicates Application and Spraying with Magnesium

“…Or that fertilizer is a substance added to soil or sprayed on vegetative system of plant to improve its growth and increase its productivity, compound fertilizers that contain major elements such as nitrogen, phosphorus and potassium, which are important for growth and plants development, using a balanced proportion of NPK compound fertilizer [6]. Several studies have been conducted to determine effect of NPK fertilizers in growth and flowering in ornamental plants, [7] found in an experiment on Rose bushes Carola cultivar, in a study that included adding chemical fertilizer NPK at four levels (25, 50, 75, and 100%) and comparing it with organic fertilization, addition of chemical fertilizers outperformed organic ones in flowering stems number, plant dry weight, and content of flowering stems of macro and microelements, especially at level of 100%. [8] Conducted an experiment aimed to improve flower productivity and concentration of N,P,K elements in nutrient solution, and foliar application of plant growth promoters (PGP) on Rosa Damascene and found that NPK fertilizer significantly increased in leaf nitrogen phosphor and potassium content.…”

Evaluación del uso de microorganismos de montaña activados en el cultivo de rosas, Zinacantán, Chiapas, México

“…La floricultura es una rama especializada de la horticultura dedicada al estudio y cultivo de flores de corte, follaje, plantas anuales, plantas perennes y plantas en maceta bajo invernadero y/o a la intemperie (Barbosa et al, 2019). Es una opción con mejores perspectivas que los cultivos tradicionales, debido a los mayores márgenes de rentabilidad que se pueden obtener (Cortés Jiménez et al, 2017).…”
