Crescimento De Mudas De Baru Em Substrato Enriquecido Com Nitrogênio, Fósforo E Potássio

Abstract: O baru (Dipteryx alata Vog.) é uma espécie nativa do cerrado que apresenta potencial para diversos usos, inclusive em programas de recuperação de áreas degradadas. Porém, pouco se conhece sobre seus aspectos silviculturais, principalmente suas exigências nutricionais. O objetivo com esta pesquisa foi avaliar o crescimento inicial de mudas de baru em substrato comercial enriquecido com nitrogênio, fósforo e potássio. O delineamento experimental utilizado foi o inteiramente casualizado, com cinco tratamentos e q… Show more

“…The N contents are below the recommendation of BRASIL ( 2009), which is 5 g kg -1 . This pattern causes difficulties for the development of seedlings, because N is the most required nutrient among all others and its deficiency limits plant growth (BERTI et al, 2017).…”

“…It is noteworthy that plant height is an important parameter for morphological analysis, since nutrient deficient plants have poor development, directly affecting their growth (BERTI et al, 2017). It is believed that the higher vegetative growth of seedlings observed in this substrate can be attributed to the greater availability of some nutrients present in the residues, such as nitrogen and potassium (Table 2).…”

“…Seedlings must be exposed to favorable environmental conditions during nursery production (light, substrate, water disponible and nutrients) to achieve desired quality standards. In this phase, the substrate has a supporting and nourishing function (Dalanhol et al, 2016); however, the substrate will not be able to provide all required nutrients seedling growth, making necessary the use of fertilizers (Berti et al, 2017).…”

“…Native forest species have different nutritional requirements. However, there is not only one specific recommendation for each species since most recommendations are based on commercial species requirements (Berti et al, 2017). Therefore, given the species potential and the need for studies aimed at seedlings production, the objective was to evaluate the efficiency in controlled-release fertilizer use in Cordyline spectabilis seedlings production and what is the additional cost per seedling produced.…”
