Abstract
Purpose
The use of agro-industrial subproducts is a sustainable alternative in the formulation of substrates for plants. In this study we aimed to evaluate the effect of substrates formulated from vermicompost and carbonized rice husk on production of yellow passion fruit cultivars seedlings.
Methods
Four cultivars: BRS Gigante Amarelo, FB 300, IAC 275, and Rubi do Cerrado were sown in tubes filled with six substrates from combinations of vermicompost (V) and carbonized rice husk (CRH): 100% V, 90% V + 10% CRH, 80% V + 20% CRH, 70% V + 30% CRH, 60% V + 40% CRH, and 50% V + 50% CRH.
Results
We observed that substrates with higher proportions of vermicompost presented better chemical attributes and moisture content. Seedlings from cv. BRS Gigante Amarelo and FB 300 showed higher relative water content produced in substrates with a proportion > 70% of vermicompost. The highest growth and biomass production characteristics were observed in all cultivar’s seedlings in 100% V and 90% V + 10% CRH.
Conclusion
Substrates containing 100% and 90% vermicompost contributed to obtaining passion fruit seedlings with higher growth and photoassimilates accumulation. The addition > 30% CRH in the substrate formulation impaired the production of passion fruit cultivars seedlings.
期刊介绍:
The Journal of Soil Science and Plant Nutrition is an international, peer reviewed journal devoted to publishing original research findings in the areas of soil science, plant nutrition, agriculture and environmental science.
Soil sciences submissions may cover physics, chemistry, biology, microbiology, mineralogy, ecology, pedology, soil classification and amelioration.
Plant nutrition and agriculture submissions may include plant production, physiology and metabolism of plants, plant ecology, diversity and sustainability of agricultural systems, organic and inorganic fertilization in relation to their impact on yields, quality of plants and ecological systems, and agroecosystems studies.
Submissions covering soil degradation, environmental pollution, nature conservation, and environmental protection are also welcome.
The journal considers for publication original research articles, technical notes, short communication, and reviews (both voluntary and by invitation), and letters to the editor.
