“…The greater availability of nutrients, due to higher volume, resulted in higher dry weight accumulation through the accumulation of carbohydrates, minerals, proteins, fibers and lipids in papaya seedlings. For papaya, this result of higher volume of the container is in agreement with the results obtained by MENDONÇA et al (2003), ARAÚJO et al (2006), COSTA et al (2009a) and COSTA et al (2010a. The period was more favorable to the development of seedlings in the greenhouse and Aluminet ® (Table 3) as they promote better conservation of thermal energy, since the average temperature was 22.0 °C.…”

The objective of this study was to test container of polyethylene bags and protected environments on the papaya seedlings production, from May to August of 2008, in Aquidauana state of Mato Grosso do Sul (MS), Brazil. Five bags of polyethylene were used: 7.5 cm x 11.5 cm, 205.9 cm³; 8.4 cm x 10.6 cm, 238.1cm³; 10.0 cm x 16.5 cm, 525.2 cm³; 12.0 cm x 12.0 cm, 550.0 cm³ and 15.0 cm x 21.5 cm, 1539.8 cm³. These containers were placed in three protected environments: greenhouse; screened nursery with Sombrite® and screened nursery with Aluminet®. Because there is no replication of growing environment, each one was considered an experiment. For each cultivation environment, it was adopted a completely randomized design with eight replications of two plants each. Initially, data were submitted to analysis of individual variance of the container (for each cultivation environment), then performing the evaluation of the residual mean squares and the combined analysis of these environments for comparison of protected environments. The greenhouse and nursery with thermal reflector screen produced the best seedlings. The bags of 15.0 x 21.5 cm produced the best papaya seedlings. The Dickson Quality Index pointed the nursery with screen of thermal reflector as the environment that produced the most vigorous seedlings, when using the best container.

“…Both vermiculite, which had already showed better results for other fruit (COSTA et al, 2009;COSTA et al, 2010 c), and the substrates containing 100% cattle manure or 33.33%, promoted best physical structure to the substrates (aeration, moisture retention and porosity) and facilitated nutrient absorption by baruzeiro seedlings. DIAS et al (2009) found that the use of manure above 10% in substrate reduced root development and leaf expansion of mangaba seedlings cultivated in a greenhouse, different from what was observed in the present study.…”

ABSTRACT:The high seedlings quality is essential for deployment of homogeneous orchards. This study evaluated the baruzeiro (Dipteryx alata Vog) seedlings formation on different substrates within protected environments. It was used substrates with100% of cattle manure; 100% of cassava stems; 100% of vermiculite; 50% of cattle manure + 50% of cassava stems; 50% of cattle manure + 50% of vermiculite; 50% of cassava stems + 50% of vermiculite; and + ⅓ of cattle manure + ⅓ of cassava stems + ⅓ of vermiculite. These substrates were tested in protected areas: greenhouse; black shade net of 50% shading; and aluminized thermo-reflective screen of 50% shading. A completely randomized experimental design with five replicates of four plants was adopted. Initially, data were submitted to analysis of individual variance of the substrates, in each environment of cultivation, then performing the evaluation of the residual mean square and the analysis of these environments together for comparison. The best substrate for baruzeiro seedlings was pure vermiculite. The substrates with 100% of manure and the substrate with 33.33% of the mixed studied materials can be used for seedlings formation. The environment with screen can be indicated for the production of baruzeiro seedlings, since it gave vigor to the seedlings. KEYWORDS:Dipteryx alata, cattle manure, cassava stems, vermiculite, protected cultivation. PRODUÇÃO DE MUDAS DE BARUZEIRO EM DIFERENTES AMBIENTES PROTEGIDOS E SUBSTRATOS RESUMO:A qualidade da muda é fundamental para implantação de pomares homogêneos. Desta forma, avaliou-se a formação de mudas de baruzeiro (Dipteryx alata Vog), em diferentes substratos, no interior de ambientes protegidos. Foram utilizados substratos com 100% de esterco bovino; 100% de ramas de mandioca; 100% de vermiculita; 50% de esterco bovino + 50% de ramas de mandioca; 50% de esterco bovino + 50% de vermiculita; 50% de ramas de mandioca + 50% de vermiculita e ⅓ de esterco bovino + ⅓ de ramas de mandioca + ⅓ de vermiculita. Estes substratos foram testados em ambientes protegidos: estufa agrícola; telado de tela preta com 50% de sombreamento e o telado de tela termorrefletora aluminizada com 50% de sombreamento. Foi adotado o delineamento experimental inteiramente casualizado, com cinco repetições de quatro plantas cada. Inicialmente, os dados foram submetidos às análises de variâncias individuais dos substratos em cada ambiente de cultivo, realizando em seguida a avaliação dos quadrados médios dos resíduos e a análise conjunta dos ambientes. O melhor substrato para a formação das mudas do baruzeiro foi a vermiculita pura. O substrato com 100% de esterco e o substrato com 33,33% dos materiais estudados podem ser indicados para a formação das mudas. Os telados podem ser indicados para produção de mudas de baruzeiro, pois conferiram vigor às mesmas. PALAVRAS-CHAVE:Dipteryx alata, esterco bovino, ramas de mandioca, vermiculita, cultivo protegido.

“…Aliado e interagindo com os substratos, o ambiente de cultivo protegido influência o desenvolvimento inicial da planta (Costa et al, 2009), agregando vigor às mudas e, consequentemente, melhor adaptação e pegamento a campo (Costa et al, 2011). Para Zanella et al (2006), a utilização de sombreamento é uma importante técnica na formação de mudas frutíferas, pois afeta diretamente o crescimento da planta e posteriormente a formação do pomar.…”

RESUMOEste trabalho avaliou tecnologias de ambientes protegidos e substratos para a produção de mudas de Dipteryx alata Vog. Foram utilizados dois ambientes protegidos: telado agrícola, fechamento em 90° graus, com tela preta nas laterais e aluminizada na cobertura, ambas de 50% de sombreamento; telado agrícola, fechamento em 45° graus, com tela preta nas laterais e cobertura, de 50% de sombreamento. Em cada ambiente foram testados substratos de mistura de esterco bovino (E) e vermiculita (V): 100% E + 0% V; 90% E + 10% V; 80% E + 20% V; 70% E + 30% V; 60% E + 40% V; 50% E + 50% V; 40% E + 60% V; 30% E + 70% V; 20% E + 80% V; 10% E + 90% V. O telado preto propiciou mudas de melhor qualidade e os substratos com baixas porcentagens de esterco (10, 20 e 30%) são os mais propícios para a formação de mudas de Dipteryx alata Vog.Palavras-chave: baru, esterco bovino, vermiculita, ambientes protegidos. Shading Screens and Substrates for Dipteryx alata Vog. Seedling Production ABSTRACTThis study evaluated the technologies of protected environments and substrates for the production of Dipteryx alata Vog. seedlings. Two protected environments were used: agricultural screened, closing at 90 degrees, with black screen on the sides and aluminized screen on the cover, both with 50% shading; agricultural screened, closing at 45 degrees, with black screen on the sides and cover, both with 50% shading. In each environment, substrates composed of mixture of cattle manure (E) and vermiculite (V) at the following ratios were tested: 100% E + 0% V; 90% E + 10% V; 80% E + 20% V; 70% E + 30% V; 60% E + 40% V; 50% E + 50% V; 40% E + 60% V; 30% E + 70%; 20% E + 80% V; 10% E + 90% V. The black screen environment propitiates seedlings of better quality and the substrates with low percentages of cattle manure (10, 20 and 30%) are the most propitious for the formation of Dipteryx alata Vog. seedlings.
