Pfaffia glomerata (Spreng) Pedersen em cultivo solteiro e consorciado com Tagetes erecta L. e Ocimum basilicum L.

Abstract

The experiment was carried out in the medicinal garden of the Universidade Federal da Grande Dourados- UFGD, in Dourados-MS, from the period of March 2005 to September 2006.The aim was to evaluate the yield of Pfaffia glomerata (Spreng) Pedersen in the mono-crop system and inter-cropped with Tagetes erecta L. and Ocimum basilicum L in red distroferric latossol with or without semi-decomposed poultry litter. The study objects were Suma-F, Tagetes-C and Basil-M in mono-crops and the consortia of two Suma, three Tagetes - F2C3 and three Basil - F2M3 lines, all of them with and without semi-decomposed poultry litter soil. Ten experimental designs were arranged in randomized blocks, with four repetitions. The two Suma spacing rows were of 0,50 cm and the three Basil and Tagetes rows were of 0,35 cm. Suma aerial parts fresh and dry masses productions were higher (13,22 t ha-1 and 4,39 t ha-1, respectively) in mono-crops, independently on the use of poultry litter. Nevertheless, none of the experimental designs influenced the dry and fresh masses and root number in Suma which were on average 10,02 e 2,07 t ha-1 and 41.7916 roots ha-1, respectively. Roots diameter was higher (23,5 mm) in the inter-crop with Basil. Tagetes floral capitula dry and fresh masses productions were higher (14,28 t ha-1and 12,78 t ha-1, respectively) inter-cropped with Suma but only the capitula fresh masses productions were higher with the use of poultry litter. Basil aerial parts productions were higher in consortium, independently on which species; however, they were not influenced by the use of the poultry litter. Equivalent area rate – EAR for the Suma consortium with Tagetes was 2, 15 with the poultry litter and 1, 99 without the poultry litter and for Basil it was 2, 44 with the poultry litter and 3,08 without the poultry litter. As the values were higher than 1, 0, they indicate that the consortia were effective.
