Previous issue date: 2011-02-21 / The work was carried out in Dourados-MS, between March, 2007, and January, 2008, in
Distroferric Red Latossol, very clay texture. The aim was to study ‘Amarela de Carandaí’
peruvian carrot that was cultivated in soil with chicken manure – DF (0, 5, 10, 15 and 20 t
ha-1) and under two-2F or three-3F rows of plants per plot, which resulted in 66,000 and
99,000 plants ha-1. Those ten treatments were arranged as 5 x 2 factorial scheme in
randomized block experimental design, with four replications. Harvests were done on 210
and 248 days after planting (DAP), when plants showed more than 50% of senescence of
foliar part, respectively. Plant heights were not influenced significantly by CF doses neither
by number of rows in harvest done on 210 DAP, with average of 30.70 cm. On 248 DAP,
plant heights showed linear growth as a function of CF doses, which highest value was
24.20 cm under 20 t ha-1 of CF. Yields of fresh masses of leaves, crowns and shoots were
influenced significantly by CF doses. The greatest yield, regarding to number of rows, were
obtained under 3F on both two harvests. On 210 DAP, the greatest yield of commercial roots was 10.86 t ha-1 with the use of 16.36 t ha-1 of CF and, on 248 was 14.00 t ha-1 with the use of 20 t ha-1 of CF. Yields of fresh masses of non-commercial roots, on 210 DAP, dried mass of leaf and of commercial root on 248 DAP, were influenced significantly by chicken manure doses as soil covering and number of rows per plot interaction, and showed quadratic growth with different rates. In harvest done on 248 DAP, it was obtained the greatest yields of fresh mass of non-commercial roots (5.94 t ha-1) with the use of 14.86 t ha-1 of CF, and of dried mass of leaves, with 3F (2.11 t ha-1), and of commercial root with 2F (2.87 t ha-1) with dose of 20 t ha-1 of CF. Yields of dried mass of shoot and crown on 210 DAP and of crown and non-commercial root on 248 DAP were influenced significantly by chicken manure doses. The greatest accumulating of dried mass were 1.0 t ha-1 of shoots, with the use of 13.71 t ha-1 of CF; 1.22 t ha-1 of crown with 13.59 t ha-1 of CF, on 210 DAP and 1.18 t ha-1 of no-commercial root with the use of 13.98 t ha-1 of CF, on 248 DAP. The greatest yield of commercial roots of Peruvian carrot was obtained under three rows of plants, using 20 t ha-1 of chicken manure as soil covering, which harvest was done on 248 DAP, with 70% of senescence of aerial part. / O trabalho foi desenvolvido em Dourados-MS, entre março de 2007 e janeiro de 2008, em Latossolo Vermelho distroférrico, de textura muito argilosa. O objetivo foi estudar a mandioquinha-salsa ‘Amarela de Carandaí’, cultivada em solo com cama-de-frango-CF (0, 5, 10, 15 e 20 t ha-1) e sob duas-2F ou três fileiras-3F de plantas no canteiro, resultando em 66.000 e 99.000 plantas ha-1. Os dez tratamentos foram arranjados como fatorial 5 x 2, no delineamento experimental blocos casualizados, com quatro repetições. Foram realizadas colheitas aos 210 e 248 dias após o plantio (DAP), quando as plantas apresentavam mais de 50% e 70% de senescência da parte foliar, respectivamente. As alturas das plantas não foram
influenciadas significativamente pelas doses de CF e nem pelo número de fileiras, na colheita aos 210 DAP, com média de 30,70 cm. Aos 248 DAP, a altura das plantas apresentou crescimento linear em função das doses de CF, sendo o maior valor 24,20 cm, sob 20 t ha-1 de CF. As produções de massas frescas de folhas, coroas e rebentos foram influenciadas significativamente pelas doses de CF. As maiores produções, quanto ao número de fileiras, foram obtidas sob 3F, nas duas colheitas. Aos 210 DAP, a maior produção de raízes comerciais foi de 10,86 t ha-1 com o uso de 16,36 t ha-1 de CF e, aos 248 DAP foi de 14,00 t ha-1, com o uso de 20 t ha-1 de CF. As produções de massas frescas de raiz não-comercial, aos 210 DAP, massa seca de folha e de raiz comercial aos 248 DAP, foram influenciadas significativamente pela interação doses de cama-de-frango em cobertura do solo e número de fileiras de plantas no canteiro, apresentando crescimento quadrático com taxas diferentes. Na colheita realizada aos 248 DAP obtiveram-se as maiores produções de massa fresca de raiz não-comercial (5,94 t ha-1), com o uso de 14,86 t ha-1 de CF, e de
massa seca de folhas, com 3F (2,11 t ha-1), e de raiz comercial, com 2F (2,87 t ha-1) na dose de 20 t ha-1 de CF. As produções de massa seca de rebento e coroa aos 210 DAP e de coroa e raiz não-comercial aos 248 DAP foram influenciadas significativamente pelas doses de cama-de-frango. Os maiores acúmulos de massa seca foram de 1,0 t ha-1 de rebentos, com o uso de 13,71 t ha-1 de CF; de 1,22 t ha-1 de coroa com 13,59 t ha-1 de CF, aos 210 DAP e de 1,18 t ha-1 de raiz não-comercial com o uso de 13,98 t ha-1 de CF, aos 248 DAP. A maior produtividade de raízes comerciais da mandioquinha-salsa foi obtida sob três fileiras de plantas, utilizando 20 t ha-1 de cama-de-frango em cobertura do solo, realizando a colheita aos 248 DAP, com 70% de senescência da parte aérea.
