This study aimed to apply the soil water balance to assess the need and frequency of irrigation in the cultivation of passion fruit grown in a sandy soil in Jaguaruna, south coast of Santa Catarina State, Brazil. Data of precipitation in Jaguaruna (code 02849020, latitude 28 ° 36'24 "S, longitude 49 º 01'59" W) for the period 1977-2013 were used. Values of average reference evapotranspiration were used per five days intervals, estimated by Penman-Monteith model. Water demands and monthly irrigation needs were determined using the water balance, assuming as 25 mm the soil storage capacity of water (CAD). Soil water balance with and without irrigation and, irrigation at the time of available water reaching 50% of the CAD value were simulated. Results showed that for the period of cultivation the average rainfall was 1237.3 mm and the maximum crop evapotranspiration was 1082.3 mm. Water surpluses and deficit occurred in all months, whereas the highest water deficit occurred in November and December. Although the rain in the region is considered well distributed along the year, it appears that the water deficit occurs frequently above 90% in all months from October to May, but only in January that was not verified water deficit in all years analyzed. December presented the largest deficit periods, with an average of 20.4 days observed. In cultivation without irrigation, the deficit period was in average 5 days for January, with no deficits in some years. The maximum deficit length was 25 days. The highest duration values were observed in September, with an average of 5.84 days. When the water balance was simulated with irrigation, the average demand for irrigation was 646.0 mm, and averaged 43.2 irrigations during the crop cycle. The greatest demand occurs in December with average of 107 mm and average number of irrigations of 6.7. It can be concluded that due to the low capacity of water retention combined with the uneven distribution of rainfall, irrigation is necessary to sustain production and quality of passion fruit in this sandy soil. The irrigation system must be sized as supplementary with short interval between irrigations. Due to soil fertility limitation, the use of fertigation can add a gain in productivity and quality of production MenosThis study aimed to apply the soil water balance to assess the need and frequency of irrigation in the cultivation of passion fruit grown in a sandy soil in Jaguaruna, south coast of Santa Catarina State, Brazil.

O melhoramento genético de arroz irrigado na Epagri tem por objetivo o constante desenvolvimento de novas cultivares mais produtivas, de melhor qualidade de grãos, com alto rendimento industrial e com tolerâncias a estresses abióticos. A mais recente cultivar de arroz irrigado lançada pela Epagri é a SCS 116 Satoru. É uma cultivar de porte moderno com características agronômicas superiores a testemunha Epagri 108, e portanto, é recomendada para o cultivo em Santa Catarina e considerada adequada aos processos de beneficiamento para arroz branco e parboilizado.
