Abstract
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.
Highlights
Guava (Psidium guajava L.) belongs to the family Myrtaceae, which includes more than 70 genera and approximately 2,800 species (Pereira, 1995; Somogyi et al, 1996)
The harvested area was estimated at 2819 hectares, covering 58.2% of the guava production area of the state of São Paulo
Our study suggests that these farms are characterized by a preference for the Paluma guava variety, spaced 7m x 5m apart, and pruned over the entire year, which generates an average annual yield of 110 kg plant-1
Summary
Guava (Psidium guajava L.) belongs to the family Myrtaceae, which includes more than 70 genera and approximately 2,800 species (Pereira, 1995; Somogyi et al, 1996). Guava (P. guajava) is the most economically important species in Brazil, several other Psidium species produce fruits and wood or are ornamental, presenting potential for commercial exploitation (Bezerra et al, 2006; Sousa et al, 2017). The increased guava production in Brazil is related to the growing consumption of fruit in its fresh form, and products originating from its industrialization (Quintal et al 2017). Many food industry products contain guava, such as juice, nectar, pulp, jam, jelly, slices in syrup, fruit bar, dehydrated products, additive to other fruit juices and its consumption as fresh fruit, guava has attained real economic importance in all the world’s tropical and subtropical regions (Kadam et al, 2012; Leite et al 2006).
