Aduba??o fosfatada e pot?ssica no cultivo de pitaia. 2016. 81 p. Disserta??o (Mestrado) ?

Por se tratar de uma cultura recente no pa?s, informa??es sobre a aduba??o mineral s?o essenciais para subsidiar a adequa??o do sistema de produ??o nas condi??es brasileiras. Nesse sentido, a pesquisa foi realizada com o objetivo de estudar diferentes doses de f?sforo e pot?ssio no crescimento inicial e na produ??o de esp?cies de pitaia. Dois experimentos foram realizados para avaliar o efeito da aduba??o fosfatada e a pot?ssica, de forma isolada. O experimento com aduba??o fosfatada foi conduzido em casa de vegeta??o, por um per?odo de 14 meses. As esp?cies de pitaia estudadas foram Hylocereus undatus, Hylocereus polyrhizus e Selenicereus megalanthus, e as doses de P2O5 foram de 0; 90;180 e 360 mg dm-3. O experimento com aduba??o pot?ssica foi conduzido em condi??es de campo, no munic?pio de Couto Magalh?es de Minas, MG. As esp?cies de pitaia avaliadas foram H. undatus e H. polyrhizus, cultivadas no espa?amento 3 m x 3 m e as doses de K2O 0; 50; 100 e 200 g planta-1. As avalia??es foram realizadas nos ciclos produtivos 2013/2014, 2014/2015 e 2015/2016. Na avalia??o do crescimento inicial das esp?cies de pitaia foi observado maior crescimento das plantas com a aplica??o de 209 mg dm-3 de P2O5 para S. megalanthus, 195,7 mg dm-3 de P2O5 para H. undatus e 360 mg dm-3 de P2O5 para H. polyrhizus. No pomar adubado com pot?ssio, no primeiro ano de cultivo, a maior produ??o foi alcan?ada com as doses de 120 g de K2O, para H. undantus e 200 g de K2O, para H. polyrhizus. A melhor qualidade de frutas foi verificada com a aplica??o de 126,6 a 137,4 g de K2O. No segundo e no terceiro ciclo produtivo, a aduba??o pot?ssica n?o aumentou a produ??o e a qualidade das frutas produzidas pela esp?cie H. polyrhizus e a dose de 200 g de K2O aumentou em 64,6% e 54,2% a produ??o da H. undantus, respectivamente. A aduba??o fosfatada favoreceu o crescimento de brota??es e do sistema radicular das tr?s esp?cies de pitaia. As esp?cies de pitaia apresentam exig?ncias distintas em rela??o ? aduba??o fosfatada para o crescimento inicial. A aduba??o pot?ssica aumentou a produ??o e proporcionou melhoria na qualidade das frutas. A esp?cie H. undantus apresentou maior exig?ncia em pot?ssio, com maior incremento de produ??o e no tamanho das frutas.Submitted by Jos?

However, because it is a recent culture in the country, information about the mineral fertilization are essential to subsidize the adaptation of the production system in the Brazilian conditions. In this sense, the research was conducted with the aim of studying different doses of phosphorus and potassium in the initial growth and production of pitaya species. Two experiments were conducted to evaluate the effect of phosphorus and potassium fertilizers an isolated way. The experiment with phosphorus fertilization was conducted in greenhouse for a period of 14 months. The species studied were of pitaya Hylocereus undatus, Hylocereus polyrhizus and Selenicereus megalanthus and the doses of P2O5 0; 90; 180 and 360 mg dm-3. The experiment with potassium fertilization was conducted in field conditions in the city of Couto Magalh?es de Minas. The species evaluated were pitaya Hylocereus undatus and hylocereus polyrhizus, cultivated in the spacing 3 m x 3 m and the doses of K2O 0; 50; 100 and 200 g plant-1. The evaluations were performed in productive cycles 2013/2014, 2014/2015 and 2015/2016. In the evaluation of initial growth of pitaya species was observed increased growth of plants with the application of 209 mg dm-3 of P2O5 for species S. megalanthus, 195.7 mg dm-3 of P2O5 for H. undatus and 360 mg dm-3 of P2O5 for species H. polyrhizus. In the orchard fertilized with potassium, in the first year of cultivation, the highest production was achieved with doses of 120 g of K2O for species H. undantus and 200 g of K2O for species H. polyrhizus. The best quality fruit was verified with the application of 126.6 to 137.4 g of K2O. In the second and third production cycle, potassium fertilization did not increase the production and quality of fruit produced by the species H. polyrhizus and the dose of 200 g of K2O increased in 64.6% and 54.2% the production of the species H. undantus respectively. The phosphorus fertilization favors the growth of shoots and roots of three species of pitaya. The pitaya species have different requirements in relation to the phosphate fertilizer for the initial growth. Potassium fertilization increased the production and promoted improvement in the quality of fruit. The species H. undantus presented higher demand in potassium with greatest increment of production and size of the fruit.porUFVJMA concess?o da licen?a deste item refere-se ao ? termo de autoriza??o impresso assinado pelo autor, assim como na licen?a Creative Commons, com as seguintes condi??es: Na qualidade de titular dos direitos de autor da publica??o, autorizo a Universidade Federal dos Vales do Jequitinhonha e Mucuri e o IBICT a disponibilizar por meio de seus reposit?rios, sem ressarcimento dos direitos autorais, de acordo com a Lei n?
