Relationship of agro-climatic characteristics in flowering phenology of siam citr plants (Citrus nobillias Var microcarpa L)

Abstract

The productivity of citrus plants in Indonesia is still low. This is due to the insufficient land used for citrus cultivation. Besides, several factors influence the production and quality of citrus, namely genetics, cultivation, and post-harvest handling, as well as other environmental factors, namely land. Environmental factors that affect the production and quality of citrus are soil and climate. Soil factors include altitude, topography, drainage, soil type, soil physical properties, and soil chemical properties, while climatic factors include rainfall and temperature. On a large scale, these environmental factors are difficult to modify, so to avoid the risk of damage and death, citrus plants are recommended to be planted on suitable land. The purpose of land suitability research is also intended to increase the production and quality of oranges.
