Resumo
The 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.
