Efeito da taxa de sementeira em viveiro no cultivo da couve - brassica oleracea var.acephala

Abstract

A test was performed in the F.A.E.F. with the aim of evaluating the effect of nursery sowing rate on cabbage growth [ Brassica oleracea L. var. Acephala (D.C)] in the definitive field. The design was a randomized complete block with 4 treatments and 8 replications. The sowing rates were 1, 2, 3 and 4 caps of Coca Cola per m.2 equivalent to 2.60, 5.20, 7.80 and 10.40 grams respectively. Sowing in the nursery was carried out on March 29, 2006 in rows with a spacing of 10 cm. The area of ​​the nursery was 5m2 being: 2m2 for the rate of 1 cap and 1 m2 for the other rates. The transplant was carried out 28 days after sowing at a spacing of 0.60 x 0.35 meters. Variables were evaluated: percentage of setting, number of leaves, fresh and dry weight of leaves and the ratio of weight of leaves/stems. The results showed that the sowing rate had a significant effect on all variables until the first harvest. The rate of one cap/m2 showed higher values ​​in percentage of setting, number of leaves, average yield and dry weight in the first harvest; the ratio of leaf weight / stem weight was low in relation to the other sowing rates. In the second harvest, the yield was higher than in the first harvest. The rate of one capper/m2 showed the best results, which is why it is recommended.
