The aim of the study was to determine the influence of biochar, incorporated as a soil meliorant on the growth and yield of zucchini. The experiment was carried out in the experimental field on University of Forestry - Sofia (42° 7′ N, 23° 43′ E). The soil type on the experimental field is fluvisols. Six variants have been developed: 1) V1 - pure soil; 2) V2 - with manure (4 t/ha-1 ); 3) V3 - with biochar (500 kg/ha-1 ); 4) V4 - manure (4 t/ha-1 ) + biochar (250 kg/ha-1 ); 5) V5 - manure (4 t/ha-1 ) + biochar (500 kg/ha-1 ); 6) V6 - manure (4 t/ha-1 ) + biochar (750 kg/ha-1 ). Within the experiment, the average weight of one fruit, dry matter content, water content, was determined. The dynamics of yield between different harvests were monitored. Nine harvests were implemented, with the highest yield of all variants reported at the fourth harvest. The highest yield was reported for variant 6 - 3219 kg/ha-1 , followed by variant 2 - 3168 kg/ha-1.
