Comportamento de cultivares precoces de arroz ( oryza sativa l.) submetidas a diferentes doses de sulfato de zinco. Pesquisa Agropecuária Tropical, Goiânia, v. 29, n. 2, p. 135-139, jul./dez. 1999. Disponível em: <https://www.revistas.ufg.br/pat/article/view/2863/2913>.1517-6398http://repositorio.bc.ufg.br/handle/ri/12840The lack of uirto-date infonnation on the demands ofhigh productive rice cultivars motivated the elaboration of a research aiming to evalu atethc effects of six doses ofzinc sulphate (O.O = control; 15.0; 30.0; 45.0; 60.0 and 75.0 kg/ha) on agronomic characteristics of short rice cu ltivars 'primavera' and <maravi­lha'. The treatments consisted of the combination of different cultivars and dosages of zinc sulphate, distributed in completely randomized blooks in three repetitions, making up 36 experimc:ntal units. The following aspects wcre evaluated: a) plants population up to 40 days after gennination (DAE) and ai lhe end of lhe cycle; b) plantheight; e) gnúns yield; d) weight ofl 00 gnúns. Until further experiments are carried out in order to confiem our results, the present technical recommendation should be kept in use.porAcesso AbertoArrozCultivaresSulfato de zincoRiceCultivarZinc sulphateArtigo
