Biomass production and nutrient accumulation in physalis in two edaphoclimatic conditions

Abstract

In Brazil, although there is a growing demand for physalis in the food industries, information on the nutritional management of the crop is still incipient. This study aimed to evaluate the biomass production and accumulation of nutrients in the shoots and fruit of physalis in two cultivation sites. Two field experiments were conducted, one where the soil was Typic Quartzipsamment in the municipality of Diamantina and the other where the soil was Rhodic Hapludox in the municipality of São João Evangelista, Minas Gerais State, Brazil. The experiments were conducted in a randomized complete block design with four replicates. The treatments were the evaluation period. Samples were collected every 15 days the day of planting of the seedlings in the field for a period of 240 days. Dry matter and nutrient accumulation in shoot and fruit were evaluated. The biomass production and nutrient accumulation were higher in the edaphoclimatic conditions at São João Evangelista compared to the conditions at Diamantina. Macronutrient accumulation was in the following order: N > K > Ca > S > Mg > P in shoot and N > K > P > S > Ca > Mg in fruit. Micronutrient accumulation in shoot and fruit was in the following order: Fe > Mn > Zn > B > Cu.
