Agricultural and economic characterization of guava production in Brazil

Abstract

This study was designed to analyze the relationship between guava crop production variables in the Matão region of central São Paulo, Brazil, and to better understand the economic importance of this crop to its growers. Data were obtained through a questionnaire applied during interviews with guava growers and after the data collection, statistical analyzes were made using Chi-Square hypothesis tests. Analysis results indicate a distinct association between the variables variety and plant age, between variety and number of plants per hectare, andbetween number of plants per hectare and yield, while no association was found between yield and variety. The Paluma guava variety spaced seven meters by five meters apart and pruned throughout the entire year was found to be the most common crop arrangement. The mean yield of the plots studied was 110 Kg plant-1. The use of irrigation added 22.8 Kg of guava production per plant, annually.

“…~ 60 Psidium species occur in Brazil distributed in all biomes, in several phytogeographic domains, representing great diversification 3 . Psidium guajava L. (guava tree, Psidium section) is the well-known species of the genus due to its relevance for fruit production 4 and medicinal value 5 , 6 . Other Psidium species, popularly called “araçás”, are potential genetic resources for breeding programs and medicinal purposes 7 , as well as they are relevant for taxonomic, ecological and evolutive studies in this genus 2 .…”

Chemical thinning increasing larger fruits and profit in red guava orchards

“…'Paluma' is a traditional guava widely grown in Brazil, highly productive, features red-colored pulp, pleasant aroma with medium fruits and much appreciated by consumers (Ribeiro et al, 2020). This is the cultivar with the highest production in the state of São Paulo (Vitti et al, 2020).…”

“…Guava (Psidium guajava L.) is grown successfully in a wide range of climatic and edaphic conditions [1], in rural and urban areas, or among native vegetation on disturbed lands. In 2016, the southeast region of Brazil produced 44.3% of all guava grown in the country, and the state of São Paulo alone produced 34.92%, corresponding to 146,943 tons [2].…”
