Pesquisa do Estado de Minas Gerais (FAPEMIG) / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq) / A fisalis (Physalis peruviana L.) ? uma planta herb?cea da fam?lia Solanaceae. ? uma esp?cie produtora de frutos comest?veis com sabor azedo e adocicado, caracterizados como uma baga carnosa. Possui grande potencial de cultivo que vem despertando a aten??o de produtores, comerciantes e consumidores. O objetivo deste trabalho foi avaliar a necessidade calagem, determinar a satura??o de alum?nio tolerada, satura??o por bases desejada e o requerimento de c?lcio e magn?sio para a cultura da fisalis. Foi utilizado delineamento inteiramente casualizado com cinco repeti??es. Foi aplicado calc?rio dolom?tico com a concentra??o de 380 g kg-1 de ?xido de c?lcio e 125 g kg-1 de ?xido de magn?sio, com poder de neutraliza??o total de 90 %, nas necessidades de calagem (NC) de 0, 0,6, 1,4 e 2,3 t ha-1 para Neossolo Quartzar?nico (NQ) e 0, 0,8, 1,8 e 2,8 t ha-1 para Latossolo Vermelho distr?fico (LVd). A altura das plantas, di?metro do coleto, massa seca da parte a?rea, massa seca de ra?zes, produ??o, di?metro longitudinal e di?metro transversal dos frutos de fisalis foram submetidos ? an?lise vari?ncia multivariada por meio do processo da vari?vel can?nica de an?lise de vari?ncia conjunta das NC e tipo de solo. Equa??es de regress?o linear foram ajustadas para cada vari?vel em fun??o das NC para cada tipo de solo. Valores ?timos de desenvolvimento da fisalis para ?ndices de acidez do solo e para concentra??es ?timas de macro e micronutrientes na folha diagn?stico foram obtidos substituindo a NC recomendada nas equa??es de regress?o. Os valores m?ximos para todos os atributos avaliados foram obtidos com a aplica??o de 1,6 t ha-1 para NQ e 2,0 t ha-1 para LVd. A calagem ? uma pr?tica essencial para o cultivo da Physalis peruviana L. em solos ?cidos, onde objetiva-se alcan?ar maiores produtividades. Os padr?es determinados para satura??o de alum?nio tolerada, satura??o por bases desejada e requerimento de c?lcio e magn?sio s?o: 5,0 %, 67 % e 2,5 cmolc dm-3, respectivamente. / Disserta??o (Mestrado) ?

It is a species that produces edible fruits with a sour and sweet flavor, characterized as a fleshy berry. It has great potential for cultivation that has been attracting the attention of producers, traders and consumers. The objective of this work was to evaluate the liming requirement, to determine the tolerated aluminum saturation, the desired base saturation and the calcium and magnesium requirement for the physalis crop. A completely randomized design with five replications was used. Calcium oxide with a concentration of 380 g kg-1 of calcium oxide and 125 g kg-1 of magnesium oxide, with total neutralization power of 90%, was applied to liming requirements (LR) of 0, 0.6, 1.4 and 2.3 t ha-1 for Typic Quartzipsamment (TQ) and 0, 0.8, 1.8 and 2.8 t ha-1 for Rhodic Hapludox (RH). The height of the plants, shoot diameter, shoot dry mass, root dry mass, yield, longitudinal diameter and transverse diameter of the fruits of fisalis were submitted to multivariate analysis using the canonical variable of analysis of variance LR and soil type. Linear regression equations were adjusted for each variable as a function of LR for each soil type. Optimum values of fisalis development for soil acidity indexes and for optimal concentrations of macro and micronutrients in the diagnostic leaf were obtained by substituting the recommended LR in the regression equations. The maximum values for all evaluated attributes were obtained with the application of 1.6 t ha-1 for TQ and 2.0 t ha-1 for RH. Liming is an essential practice for the cultivation of Physalis peruviana L. in acid soils, where it is aimed to achieve higher yields. The determined standards for tolerated aluminum saturation, desired base saturation and calcium and magnesium requirements are: 5.0 %, 67 % and 2.5 cmolc dm-3, respectively.
