No. of bitstreams: 1 RosimeirePGassi.pdf: 747244 bytes, checksum: ac38fac088a66fc0d51ed93985e235a3 (MD5) Previous issue date: 2006-02-21 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The experiment was carried out at Medicinal Plant Garden of the Federal University of South Mato Grosso UFMS, in Dourados, from October, 2004 to April, 2005. The objective was to evaluate the effect of incorporating phosphorus (P) and chicken manure (CM) to the soil on growth and yield of bardana. Five doses of phosphorus (4.3; 25.8; 43.0; 60.2 and 81.7 kg ha-1) in triple super phosphate (TSP) form, and five doses of semi-decomposed chicken manure (1,000; 6,000; 10,000; 14,000 and 19,000 kg ha-1) were studied. Nine treatments were defined using III Plan Puebla experimental Matrix: 4.3 and 6,000; 25.8 and 1,000; 25.8 and 6,000; 25.8 and 14,000; 43.0 and 10,000; 60.2 and 6,000; 60.2 and 19,000 and 81.7 and 14,000 kg ha-1, P and CM respectively. Treatments were arranged in a randomized block experimental design with four replications. Every plot had 4.5 m2 of area and twelve plants arranged in double rows with spaces of 0.50 m between plants and 0.54 m between rows. Sixty days after transplantation DAT, at each 10 days, the height of each plant was measured. On harvest, two competitive plants were taken from each plot. Maximum height of bardana (129.87 cm) was reached on 113 DAT with 60.2 and 14,000 t ha-1 of phosphorus and chicken manure, respectively, treatment. Leaf area, fresh and dried mass of total aerial part and fresh mass of leaves showed positive reaction isolately answer in relation to the studied factors. The highest values were registered for 81.7 and 1.000 kg ha-1 of P and CM treatment, respectively: 19,822.86 cm2; 48,999.73 kg ha- 1; 8,287.24 kg ha-1 and 22,869.64 kg ha-1. The highest yields of dried mass of leaves were related to the highest doses of chicken manure, while the highest yields of fresh mass of roots (2,435.57 and 2,000.98 kg ha-1) were related to the highest used doses of P and CM. Yield of dried mass of roots increased with P doses and intermediary doses of CM. Diameter and length of roots did not show significative differences between treatment and they were, in average, 9.07 mm and 18.64 cm. N contents in leaves were the highest under the highest doses of P and CM, but in roots they did not show significative differences as a function of treatments. P contents in leaves were independent on treatments, but in roots, the highest contents of phosphorus were obtained with the highest doses of chicken manure interacting with intermediary doses of P / O experimento foi desenvolvido no Horto de Plantas Medicinais, da Universidade Federal de Mato Grosso do Sul UFMS, em Dourados, no período de outubro de 2004 a abril de 2005. O objetivo foi avaliar o efeito da incorporação ao solo de fósforo (P) e de cama-de-frango (CF) sobre o crescimento e a produção da bardana. Estudaram-se cinco doses de fósforo (4,3; 25,8; 43,0; 60,2; e 81,7 Kg ha-1), na forma de superfosfato triplo, e cinco doses de cama-de-frango de corte semidecomposta (1.000; 6.000; 10.000; 14.000 e 19.000 kg ha-1). Os nove tratamentos resultantes foram definidos usando a matriz experimental Plan Puebla III: 4,3 e 6.000; 25,8 e 1000; 25,8 e 6.000; 25,8 e 14.000; 43,0 e 10.000; 60,2 e 6.000; 60,2 e 14.000; 60,2 e 19.000 e 81,7 e 14.000 kg ha-1 de P e CF, respectivamente. Os tratamentos foram dispostos no delineamento experimental blocos casualizados, com quatro repetições. Cada parcela teve área de 4,5 m2, com doze plantas arranjadas em fileiras duplas, com espaçamento de 0,50 m entre plantas e 0,54 m entre fileiras. A partir dos 60 dias após o transplante- DAT, a cada dez dias, foram medidas as alturas de todas as plantas. Por ocasião da colheita, foram arrancadas duas plantas competitivas de cada parcela. A altura máxima da bardana (129,87cm) foi alcançada aos 113 DAT, com o tratamento de 60,2 e 14.000 kg ha-1 de P e cama-de-frango, respectivamente. A área foliar, massa fresca e seca da parte aérea total e massa fresca das folhas apresentaram resposta positiva isoladamente em relação aos fatores estudados, sendo os maiores valores obtidos com o tratamento 81,7 e 1.000 kg ha-1 de P e CF, respectivamente, a saber: 19.822,86 cm 2; 48.999,73 kg ha-1; 8.287,24 kg ha-1 e 22.869,64 kg ha-1, respectivamente. As maiores produções de massa seca das folhas ocorreram sob as maiores doses de cama-de-frango, enquanto as maiores produções de massa fresca das raízes (2.435,57 e 2.000,98 kg ha-1) foram obtidas sob as maiores doses de P e CF utilizadas. A produção de massa seca das raízes aumentou com as doses de P e doses intermediárias de CF. O diâmetro e o comprimento das raízes não apresentaram diferenças significativas entre os tratamentos e foram, em média, de 9,07 mm e 18,64 cm. Os teores de N nas folhas, foram maiores sob as maiores doses de P e de CF, mas nas raízes não apresentaram diferenças significativas em função dos tratamentos. Os teores de P nas folhas, foram independentes dos tratamentos, mas nas raízes, os maiores teores de fósforo foram obtidos com as maiores doses de cama-de-frango interagindo com as doses intermediárias de P
