RESUMO

Tropical flower production has growing in Brazil, mostly by the recent interest of flower consumers on products with exotic shapes, vibrant colors and high durability. These flowers, not usual in Brazil, are still produced on low scale. Production systems have not been intensively exploited, as well as basic studies with the various varieties and species have not been conducted. Production systems that combine economic feasibility with low environmental impact should de developed for this plant group, since they adapt to a wide range of environmental conditions, including shade. Environment adaptation studies combined with mineral nutrition studies are necessary to understand and improve integrated tropical flower production, using other pla nt species under various environmental conditions. Alley cropping, used on this study, is an example of such integration. This research evaluated the performance of hybrid heliconia Golden Torch (Heliconia psittacorum L x Heliconia spathocircinada Aristigueta) under alley cropping with pigeonpea (Cajanus cajan (L.) Millsp.) and Flemingia macrophylla and a control treatment. Two rates of thermophosphate (Yorin Master 1) with or without, were combined to the previous treatments. The experiment was conducted at the Crop Science Department of Universidade Federal Rural do Rio de Janeiro. The experimental design was a split plot in complete randomized design. Lower heliconia mortality occurred on alleys formed by Cajanus cajan. Phosphate addition did not affect mortality. Higher yields of heliconia flowers were observed on Flemingia macrophylla alleys, followed by Cajanus cajan and control. Phsophate addition did not affect yields. Number of lateral shoots was affected by the plant position on the plot: central rows tended to have more shoots than lateral rows. Leaf area was higher where phosphate was applied, independently of alley cropping.
