The results of the study devoted to cultivation technology effects on the indices of yield structure of sweet maize are presented. Field trials with the crop were carried out during 2014–2016 at the dark-chestnut slightly saline drip-irrigated soil by using the randomized split plot design method in four replications. Three factors were studied in the trials: depth of mouldboard ploughing (20–22, 28–30 cm), nutritive background (no fertilizers, N60P60, N120P120), plant density (35 000, 50 000, 65 000, 80 000 plants ha-1). Increase in the depth of ploughing and plant density to 80 000 plants ha-1 leads to considerable decrease of the structural indices and yields. The best yield structure was obtained under the mouldboard ploughing at the depth of 20–22 cm, nutritive background N120P120 and plant density of 35 000 plants ha-1. The highest yields of sweet maize ears with husks (14.00 t ha-1) were achieved under the higher plant density of 65 000 plants ha-1
