S.  aResearch and the Northeast Brasilian Citrus Industry.  aInternational Citrus Symposium, p.1-12, 1990.c1990  aA review is made focussing on the influence of EMBRAPA's (Brasilian Enterprize for Agricultural Research) program on the development of the citrus industry in Northeastem Brazil, one of the poorest regions of the country. This region comprises almost 20% of the total land surface and almost 30% of the country's population and exhibits serious social and economic contrasts. Due to this extensive area (approximately 1,600,000 Km2) and the large range of climates and soils, although the annual rainfall in almost 60% of the total area is less than 750 mm, the export/import balance is always favorable. Neverthless, continually unbalanced growth between north and south has brought several social problems to the country as a whole. Recognizing this situation regarding the citrus industry in the 60's, where the citrus fruits of late ripening varieties that supplied the northeastern markets were exclusively from the State of Sao Paulo, and led by a citrus culture survey made in the Cruz das Almas area in 1961, a research program was started at the National Research Center for Cassava and Fruit Crops in order to improve varieties, extend harvest time and introduce certain cultural practices such as dense spacing. As a consequence of research results, regarding the mentioned aspects, almost 100,000 ha of citrus have been planted in the Northeast and especially in the States of Sergipe and Bahia.  aCitrus  aClima  aClone  aMaturação  aProdutividade  aSolo  aCultivar  anucellar clone  aproductivity  aspacing
