Resumo
This research was conducted in an experimental area in
Santo Antônio de Goiás (16º28'S, 49º17'W and altitude 823 m),
Brazil, during the months of June, 2004, and March, 2005. The
upland rice variety Aimoré was used along with several cover
crops aiming to evaluate leaf area, number of tillers, dry matter,
and nitrogen content in the phytomass during the rice crop cycle.
The experimental design was the randomized blocks one, with
five treatments and four replications. The treatments consisted
of different cover crops, such as velvet bean (Mucuna aterrima),
sunn hemp (Crotalaria juncea), dwarf pigeon pea (Cajanus cajan),
broom sorghum (Sorghun bicolor), and a check treatment with
spontaneous vegetation growing among the rice plants. The
leguminous plants, specially C. juncea, presented better results
in tillering production, leaf area index, dry matter yield, and
accumulated nitrogen content, if compared to the treatments where
grasses were used as soil cover crop. It was concluded that rice
presented a satisfactory development in the different soil cover
treatments, specially after leguminous cultivation.
