SANGALLI, A.; VIEIRA, M.C.; HEREDIA ZARATE, N.A. and SCALON, S.P.Q.. Development and yield of "carobinha" (Jacaranda decurrens Cham. subsp. symmetrifoliolata Farias & Proença) cultivated under two plant arrangements, with or without chicken manure covering on the soil. Rev. bras. plantas med. [online]. 2011, vol.13, n.4, pp. 439-446. ISSN 1516-0572. http://dx.doi.org/10.1590/S1516-05722011000400009.
The aim of this study was to evaluate the development and yield of "carobinha" (Jacaranda decurrens subsp. symmetrifoliolata) cultivated ex situ under two plant arrangements, with or without semi-decomposed chicken manure. This study was carried out under field conditions at the Medicinal Plant Garden (HPM), Federal University of Grande Dourados (UFGD), in Distroferric Red Latossol. Arrangements with simple and double rows and the use or not of semi-decomposed chicken manure as covering were studied as 2 x 2 factorial arrangement in a randomized block experimental design, with six replicates. The highest maximum heights (61.3 cm plant-1) at 555 days after transplant were obtained by plants cultivated under double rows with chicken manure. The mean numbers of leaves and branches per plant during the cycle were eleven and two, respectively. The mean stem diameter of plants that were cultivated in simple rows was 8.3 mm, while that of plants cultivated in double rows was 10.8 mm, both at 552 days of the cycle. The evaluated characteristics, in the harvest at 555 days after transplant, were not influenced by the interaction between plant arrangements and use of chicken manure or by factors in an isolated way. Thus, cultivation in double rows was favorable to "carobinha" yield for allowing the highest yield per area.
