Abstract

The lack of up-to-date information on the demands of high productive rice cultivars motivated the elaboration of a research aiming to evaluate the effects of six doses of zinc sulphate (0.0 = control; 15.0; 30.0; 45.0; 60.0 and 75.0 kg/ha) on agronomic characteristics of short rice cultivars ‘primavera’ and ‘maravilha’. The treatments consisted of the combination of different cultivars and dosages of zinc sulphate, distributed in completely randomized blocks in three repetitions, making up 36 experimental units. The following aspects were evaluated: a) plants population up to 40 days after germination (DAE) and at the end of the cycle; b) plant height; c) grains yield; d) weight of 100 grains. Until further experiments are carried out in order to confirm our results, the present technical recommendation should be kept in use.

KEY-WORDS: Rice; cultivar; zinc sulphate.
