“…In evaluating the initial development of guavira (Campomanesia adamantium), Vieira et al (2011) verified the specie's P requirements, obtaining a higher root yield when cultivated at high doses (380 kg ha -1 ) of the nutrient. Dechassa et al (2003) and Marschner (1997) described that the rate of root growth depends on the supply of phosphorus, which is important in transferring energy from the cell, respiration, photosynthesis.…”

Due to the scarcity of information on the use of fertilizers on the Brazilian Firetree (locally known as guapuruvu), this study aimed to evaluate the initial stages of guapuruvu (Schizolobium parahyba (Vell.) S.F.Blake.) plant growth using different doses of phosphorus (P). The experiment was conducted within a greenhouse environment in dystrophic Red-Yellow Latosol soil samples from the Brazilian Cerrado as the substrate in plastic containers with a capacity of 10 dm 3. The experimental design was completely randomized, with six treatments and four replicates each, totaling 24 experimental units. The treatments consisted of six different treatments of P: 0; 50; 100; 150; 200 and 250 mg dm-3 , using triple superphosphate as the P-source. At 150 days, the plant height, root crown diameter, number of leaves, dry matter (leaves, stems and roots) and P content in leaves, stems, roots and soil were evaluated. In addition, the Dickson Quality Index was estimated. The results showed that plants treated with doses of 100 to 250 mg dm-3 of P had higher growth rates among the analyzed variables. Guapuruvu revealed a requirement for phosphorus in the early stages of development at the studied edaphoclimatic condition, demonstrating the necessity for the application of phosphorus doses above 100 mg dm-3 via fertilizers in soils with low P availability.

“…O maior índice de clorofila observado é um bom indicador de N nas folhas das mudas de C. adamantium; salienta-se que, 50 a 70% do N nas folhas encontra-se incorporado às moléculas de clorofila (SILVA et al, 2014), fator interessante tendo em vista que a guavira é exigente em N e P para o seu crescimento (VIEIRA et al, 2011). O índice de clorofila foi próximo ao índice médio (36,0) observado por Vieira et al (2011) em C. adamantium cultivada com adubação de fósforo e nitrogênio. Assim, nota-se a importância da adição de bokashi na fase de produção de mudas.…”

A Campomanesia adamantium (Cambess.) O. Berg (Myrtaceae) é uma espécie nativa do Cerrado, com potencial medicinal e alimentício. Portanto, é necessário seu cultivo ex situ; porém, são incipientes os estudos na fase de crescimento de mudas da espécie com uso de biofertilizantes. Todavia, não há informações sobre a quantidade adequada desse material para mudas da espécie. Assim, objetivou-se conhecer o efeito do bokashi nos aspectos morfométricos e fotoquímicos em mudas de C. adamantium. Avaliaram-se cinco doses de bokashi (0,0; 5,0; 10,0; 15,0 e 20,0 g kg-1 de solo), incorporadas a um Latossolo Vermelho Distroférrico, de textura argilosa. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, e 20 mudas por unidade experimental. Houve mortalidade de 100% das mudas produzidas com 20 g de bokashi. A sobrevivência e Fv/F0 reduziram em função de doses crescentes de bokashi. O diâmetro do coleto máximo foi observado nas mudas cultivadas em solo com adição de 6,48 g de bokashi. Verificou-se crescimento do CML e LML com doses crescentes de bokashi. A adição de bokashi favorece as características morfométricas, mas acima de 15 g de bokashi é prejudicial na produção de mudas de C. adamantium.Palavras-chave: biofertilizante, frutífera nativa, planta medicinal, Myrtaceae. BOKASHI ON SEEDLINGS OF Campomanesia adamantium (Cambess.) O. Berg: MORPHOMETRIC AND PHOTOCHEMICAL ASPECTS ABSTRACT: The Campomanesia adamantium (Cambess.) O. Berg (Myrtaceae) is specie native to the ‘Cerrado’, with medicinal and food potential. Therefore, it’s necessary ex situ cultivation; however, the studies in growth phase of seedlings of the species with use of biofertilisers are incipient. However, there isn’t information on adequate amount of this material for seedlings of the species. Thus, objective was to know the effect of bokashi on morphometric and photochemical aspects in C. adamantium seedlings. Five doses of bokashi (0.0, 5.0, 10.0, 15.0 and 20.0 g kg-1 soil), added in a Dystroferric Red Latosol, of clay texture, were evaluated. The experimental design was in randomized block, with four replicates, 20 seedlings per experimental unit. There was mortality of 100% of the seedlings produced with 20 g bokashi. Survival and Fv/F0 decreased as a function of increasing doses of bokashi. The maximum collar diameter was observed in seedlings cultivated in soil with addition of 6.48 g bokashi. There was growth of CML and LML with increasing doses of bokashi. The addition of bokashi favors the morphometric characteristics, but above 15 g bokashi is harmful in the production of C. adamantium seedlings. Keywords: biofertilisers, native fruits, medicinal plant, Myrtaceae.

“…Mudas de C. adamantium também responderam à adubação mineral com fósforo e nitrogênio, sendo que a maior altura observada entre os tratamentos foi de 38,12 cm, com 380 e 84 kg ha -1 de fósforo (superfosfato simples) e nitrogênio (sulfato de amônio), respectivamente, aos 261 dias após o transplantio. Esses nutrientes promoveram maiores teores de nutrientes nas folhas e produção de biomassa (Vieira et al, 2011).…”
