Resíduos orgânicos e nitrogênio na produção de biomassa da capuchinha (Tropaeolum majus L.) 'Jewel' Organic residue and nitrogen on the biomass production of nasturtium (Tropaeolum majus L.) 'Jewel'

Abstract

Realizou-se este trabalho com o objetivo de avaliar o crescimento, desenvolvimento e a produção de flores de Tropaeolum majus L., em função do uso de cama de frango e de resíduo orgânico misto, associados ou não ao nitrogênio. O trabalho foi desenvolvido no Horto de Plantas Medicinais - HPM, da Universidade Federal de Mato Grosso do Sul - UFMS, em Dourados - MS, no período de maio a outubro de 2002. Os tratamentos em estudo foram testemunha (solo normal) - T, nitrogênio (60 kg.ha-1 N, na forma de sulfato de amônio) - N, cama (15000 kg ha-1 de cama de frango semidecomposta) - CF, cama mais nitrogênio - CFN, resíduo misto (15000 kg ha-1) - RM e resíduo misto mais nitrogênio - RMN, dispostos no delineamento experimental de blocos casualizados, com quatro repetições. As características avaliadas foram: altura das plantas, biomassa fresca e seca da parte aérea sem flores, biomassa fresca e seca das flores, número de flores, diâmetro e altura das flores, teor de N e P nas folhas e flores. A maior altura da planta foi de 36,33 cm no tratamento CF. As plantas do tratamento CFN apresentaram as maiores produções de biomassa fresca (52195,69 kg.ha-1) e seca (6281,14 kg ha-1) de parte aérea sem flores, e de biomassa fresca (3150,97 kg.ha-1), seca (232,17 kg ha-1) e de número de flores (50,49 milhões ha-1). Os diâmetros e os comprimentos das flores não variaram com os tratamentos utilizados. Os teores médios de N (33,0 e 32,0 g kg-1) e de P (1,9 e 3,3 g kg-1) nas folhas e nas flores, respectivamente, estiveram dentro daqueles citados para a espécie.The objective of this work was to evaluate growth, development and yield of Trapaeolum majus L. flowers as a function of the use of chicken manure and mixed organic residue associated or not with Nitrogen. The work was carried out at Medicinal Plant Garden - HPM of the Federal University of Mato Grosso do Sul - UFMS, in Dourados - MS, from May to October, 2002. Studied treatments were control (normal soil) - T, nitrogen (60 kg.ha-1 of N, in ammonia sulfate form) - N, chicken manure (15000 kg ha-1 of semi-decomposed chicken manure) - CF, chicken manure associated with nitrogen - CFN, mixed residue (15000 kg ha-1) - RM and mixed residue associated with nitrogen - RMN, which were established in a randomized experimental design with four replications. Evaluated characteristics were plant height, dried and fresh matter of aerial part without flowers, fresh and dried matter of flowers, flower diameter and height, N and P content in leaves and flowers. The highest plant height was of 36.33 cm in CF treatment. Plants from CFN treatment showed the greatest yield of fresh (52,195.69 kg.ha-1) and dried (6,281.14 kg.ha-1) matters of aerial parts without flowers, and of fresh (3,150.97 kg.ha-1) and dried (232.17 kg.ha-1) matters and number of flowers (50.49 millions.ha-1). Diameters and heights of flowers did not varied with treatments used. The highest contents of N (35.6 g kg-1) and of P (2.5 g kg-1) in leaves were with the use of CF. For flowers, the use of mixed residue associated with nitrogen - RMN resulted in 35.8 g kg-1 of N and the use of nitrogen - N in 3.9 g kg-1 of P.
