Abstract

Foi estudada a cebolinha Todo Ano, cultivada em solo sem e com 10 t ha-1 de cama-de-frango semidecomposta aplicada em cobertura e com zero, uma e duas amontoas, com duas épocas de colheita. Os tratamentos foram arranjados como fatorial 2 x 3, no delineamento experimental de blocos casualizados, com cinco repetições. As plantas foram colhidas aos 64 dias após o plantio e aos 40 dias após o corte anterior (104 dias após o plantio). A maior (38,1 cm) e a menor (27,2 cm) altura das plantas foram obtidas no tratamento com e sem cama-de-frango em cobertura e uma amontoa, respectivamente. O maior diâmetro de coleto dos perfilhos foi de 5,92 mm aos 64 dias após o plantio, no tratamento com cama-de-frango e sem amontoa e o menor foi de 4,56 mm aos 104 dias após o plantio, no tratamento sem cama-de-frango e com amontoa. A maior produção de massa fresca ocorreu na segunda colheita, em relação à primeira, independente dos fatores em estudo. A melhor renda total foi do tratamento com cama-de-frango e com duas amontoas (R$ 23.511,00), porque teria induzido lucro de R$ 2.611,00 em relação àquele com uma amontoa, que foi o pior dentro dos com cama-de-frango, e de R$ 13.619,00 em relação ao tratamento sem cama-de-frango e sem amontoas, que induziu o maior ganho nos sem cama-de-frango. 'Todo Ano' bunching onion was studied and cultivated in soil without and with covering of semi-decomposed chicken manure in doses of 0 and 10 t ha-1 with 0, 1 and 2 hillings, with two harvest dates. The treatments were arranged in a 2 x 3 factorial scheme, in an experimental randomized blocks design, with five replications. Plants were harvested 64 days after planting and 40 days after the last cut (104 days after planting). The tallest (38.1 cm) and the shortest (27.2 cm) plant heights were obtained using treatments with and without covering of chicken manure and one hilling, respectively. The widest diameter of the tiller neck was 5.92 mm at 64 days after planting in with chicken manure treatments and without hilling and the smallest was 4.56 mm at 104 days after planting, in without chicken manure treatment with one hilling. The greatest yield of fresh mass was on the second harvest, in relation to the first, regardless of the studied factors. The best total income was with chicken manure treatment and with two hillings (R$ 23,511.00) because it induced a gain of R$ 2,611.00 in relation to those with one hilling, which was the worst in with chicken manure treatments, and of R$ 13,619.00 in relation to without chicken manure treatment and without hillings which induced the greatest gain in without chicken manure treatments.
