Os tratamentos foram arranjados em esquema fatorial 4 x 3, no delineamento experimental blocos casualizados, com cinco repetições, onde foram aplicados quatro doses de cama de frango (0; 5; 10; 15 t ha-1) semidecomposta em cobertura ao solo e três amontoas, sendo zero, uma (45 dias após o plantio – DAP) e duas amontoas (45 e 75 DAP). Foram realizadas duas colheitas, aos 212 e 228 DAP, visando otimizar os resultados. A maior massa fresca de folhas (6,99 t ha-1) foi obtida aos 212 DAP, com adição de 13,36 t ha-1 de cama de frango, e a massa seca foi de 1,08 t ha-1 com 12,23 t ha-1 de cama de frango. Os maiores valores de massas frescas e secas de rebentos foi aos 228 DAP, onde a massa fresca (9,12 t ha-1) foi obtida com 15 t ha-1 de cama de frango e uma amontoa, e a massa seca (1,36 t ha-1) com 8,20 t ha-1 de cama de frango e sem o uso de amontoas. As máximas massas frescas (4,92 t ha-1) e secas (0,98 t ha-1) de coroas de plantas de mandioquinha-salsa foram obtidas aos 212 DAP, no tratamento com 15 t ha-1 de cama de frango e duas amontoas. A maior massa fresca de raízes comercializáveis foi de 15,15 t ha-1 nas plantas do tratamento com 11,50 t ha-1 de cama de frango na colheita realizada aos 212 DAP, e 20,95 t ha-1 nas plantas cultivadas em solo coberto com 6,61 t ha-1 de cama de frango e sem o uso de amontoa aos 228 DAP. O cultivo da mandioquinha-salsa ‘Amarela de Carandaí’ cultivada em solo com 5 t ha-1 de cama de frango em cobertura e com uma amontoa, aos 228 DAP, teve a maior produtividade de raízes comercializáveis (20,78 t ha-1), com renda bruta de R$ 62.340,00 e renda líquida de R$ 55.047,17, superando em R$ 27.503,00 à menor renda líquida obtida com as plantas cultivadas em solo sem cobertura com cama de frango e sem amontoa. Concluiu-se que, para obter maior renda líquida, o cultivo das plantas de mandioquinha-salsa deve ser feito em solo coberto com 5 t ha-1 de cama de frango, deve ser feita uma amontoa e a colheita deve ser realizada aos 228 DAP. The experimental work has as aim to evaluate agro-enconomic yield of ‘Amarela de Carandaí’ Peruvian carrot that were cultivated in soil covered with different doses of chicken manure and with different number of hills. Treatments were arranged as 4 x 3 factorial scheme, in randomized block experimental design with five replications, where four doses of semi-decomposed chicken manure (0; 5; 10; 15 t ha-1) as soil covering and three hills, which were zero, one (on 45 days after planting – DAP) and two (45 and 75 DAP) hills, were applied. Two harvests were done, on 212 and 228 DAP, in order to optimize results. The highest fresh weight of leaves (6.99 t ha-1) was reached on 212 DAP, with the addition of 13.36 t ha-1 of chicken manure, and dry weight was 1.08 t ha-1 with 12.23 t ha-1 of chicken manure. The highest values of fresh and dry weight of shoots was on 228 DAP, in which fresh weight (9.12 t ha-1) was obtained with 15 t ha-1 with chicken manure and one hill, and dry weight (1.36 t ha-1) with 8.20 t ha-1 of chicken manure and without the use of hilling. The maximum of fresh (4.92 t ha-1) and dry (0.98 t ha-1) crowns of Peruvian carrot plants were reached on 212 DAP, in treatment with 15 t ha-1 of chicken manure and two hills. The highest fresh weight of commercial roots was 15.15 t ha-1 in plants under treatment with 11.50 t ha-1 of chicken manure and harvest done on 212 DAP, and 20.95 t ha-1 in plants cultivated in soil coverd with 6.61 t ha-1 of chicken manure and without the use of hill on 228 DAP. The cultivation of ‘Amarela de Carandaí’ Peruvian carrot that was cultivated in soil with 5 t ha-1 of chicken manure as covering and with one hill, on 228 DAP, has the greatest yield of commercial roots (20.78 t ha-1), with gross income of R$ 62,340.00 and net income of R$ 55,047.17, which was superior in R$ 27,503.00 than the smallest net income that was obtained with plats cultivated in soil without covering with chicken manure and without hilling. It was concluded that, in order to obtain the greatest net income, the cultivation of Peruvian carrot must be done in soil covered with 5 t ha-1 of chicken manure, one hill and harvest on 228 DAP.
