Renovação de cacaueiros velhos na Bahia
Two obstacles are still limiting the program of renovating old cacao plantings in Bahia: lack of improved planting material in sufficient quantity to supply the needs of the program, and the farmers' resistance to the elimination of old cacao trees before planting new varieties. The problem of lack of improved planting material is being resolved by the production, on a relatively large scale, of hand pollinated seed and by the establishment of open pollinated seed gardens. It is anticipated that the number of hybrid seeds produced by the recently established seed gardens will reach an average of about 60 million seeds per year by 1977. During the last two years, two methods of replanting have been tested in different localities: complete clearance of the old field before establishing new plants, and removal of shade trees, leaving old cacao as provisional shade for the new plants during the first 3 or 4 years. Up to now, no substantial difference has been observed between the two methods with regard to performance of the new plants. Although it is considered too soon to recommend the second method for extensive use, the results so far obtained clearly show the economic advantages of this method as compared to total clearing mainly due to the fact that, the returns from plants commonly recommended as provisional shade, such as banana and cassava, have little commercial value in Bahia as compared to cacao
