Abstract: The development of models that allow forecasting yield tendencies is important to all sectors of the citrus industry. This work evaluated the influence of meteorological variables in different phases of the crop cycle in order to propose empirical models to estimate the number of fruits per plant (NFP) of 'Valencia' and 'Hamlin' sweet oranges. NFP sampling data from the citrus juice industry of the State of São Paulo, on the total of 15 harvests (1990/91 to 2004/05), classified into three age classes, and mete… Show more

“…The performance of FRBOX at LIM (Figure 8) was practically the same as BAU, being the bud formation (April) and vegetative dormancy (July) phases, which are the ones that are more sensitive to DEF at the development year. Paulino et al (2007), found that for LIM region the number of fruits per plant showed significant correlation with DEF of July to September of the development year. At production year (2) the most sensitive period for DEF at LIM is between the end of fruit growth and start of maturity (May and June).…”

“…While the other factors that affect production and plant development are constant weather condition which varies from year to year and it is considered as the main factor that cause yield and quality variability (Paulino et al, 2007). Agrometeorological models are tools used to understand the influence of climatic variables on crop production, being a way to summarize the responses of the crop to the climate (Rolim et al, 2008).…”

“…Economics, plant-health problems, and lower juice consummation around the world (Neves et al 2012) have forced the citrus industry to find new alternatives for ensuring its future. Climate is the major factor influencing the yield and quality of oranges (Paulino et al 2007). Anticipating fruit quality before the harvest is fundamental for producers to plan their crops (Ruslan et al 2012).…”

“…De acordo com Mattos Júnior et al (2004) e Quaggio et al (2003), são vários os fatores que podem interferir negativamente na massa e na produtividade de frutos de citros, dentre eles o manejo inadequado das adubações com consequentes desequilíbrios nutricionais proporcionados por adubações insuficientes ou desequilibradas e outros fatores mais comuns, como: a alternância de produção (Ramos-Hurtado et al, 2006;Sartori et al, 2007), a alta temperatura e o estresse hídrico (Paulino et al, 2007), além de doenças como a podridão floral dos citros, a leprose e a mancha-preta.…”
