ABSTRACT

Os objetivos do trabalho foram avaliar a produtividade e a renda bruta de cebolinha 'Todo ano' e da Rúcula 'Cultivada', sob cultivo solteiro e consorciado, com -C e sem -S cobertura do solo com cama-de-frango -CF. A colheita da rúcula foi aos 81 dias após a semeadura e da cebolinha aos 18, 139 e 174 dias após o plantio. A cultura das cebolinhas foi influenciada pelo tipo de cultivo na primeira colheita e pela cobertura do solo nas três colheitas. As menores e maiores massas frescas médias de cebolinha obtidas na primeira (1,55 e 3,58 t ha-1) e na segunda rebrota (1,31 e 3,07 t ha-1) superaram em 355,88 e 285,29 e em 203,39 e 160,17, respectivamente, a menor (0,34 t ha-1) e a maior produção (1,18 t ha-1) da primeira colheita. A maior altura (24,59 cm) e a maior massa fresca (11,40 t ha-1) das plantas de rúcula foram do cultivo solteiro com CCF. Ao relacionar as razões de área equivalente - RAEs (1,29 e 1,71) e as rendasbrutas (R$34,695,95 e 16.251,10) obtidas nos solos CCF e SCF, respectivamente, observou-se que a menor RAE induziu à maior renda bruta. Na cebolinha, as maiores produtividade e renda bruta foram com o cultivo em solo CCF e, para o mercado de Dourados, pode-se aproveitar a rebrota das plantas. Para rúcula, foi melhor o consórcio com a cebolinha em solo CCF.


The objectives of this work were to evaluate yield and gross income of 'Todo Ano' bunching onion and'Cultivada' roquette under mono-cropping and intercropping system, with (C) and without (S) soilcovering with chicken manure (CF). Harvest of roquette was on 81 days after sowing and of bunchingonion on 81, 139 and 174 days after planting. Height of bunching onion was influenced by type ofcropping in the first harvest and by soil covering in both three harvests. The greatest and the smallestaverage fresh masses of bunching onion which were obtained in the first (1.55 and 3.58 t ha-1) and in thesecond (1.31 and 3.07 t ha-1) re-sprouting were superior in 355.88% and 285.29% and in 203.39% and160.17%, respectively, than the smallest (0.34 t ha-1) and the greatest yield (1.18 t ha-1) of the first harvest The highest height (24.59 cm) and the greatest fresh mass (11.40 t ha-1) of roquette plants were frommono-cropping system with CF soil covering. Relating Land Equivalent Ratios-LER (1.29 and 1.71) withgross income (R$ 34,695.95 and 16,251.10) which were obtained from soils CCF and SCF, respectively, it wasobserved that the smaller LER induced the best gross income. For bunching onion, the highest yield andgross income were obtained with mono-cropping system in soil CCF and, for Dourados market, the re-sprouting of plants can be used. For roquette, intercrop system with bunching onion in soil CCF was the best
