As a result of research it was established that fertilizers application in dose N150Р90K180 of ordinary fertilizers is equivalent to dose N150P81K172 of complex fertilizers against the background of manure 60 t/ha has provided practically equal cabbage yield 81,2 t/ha and 79,8 t/ha accordingly, and application of these doses against the ground without manure application has made 74,8 and 76,1 t/ha accordingly. The cabbage positively responded on complex mineral fertilizers application in dose N150P81K172 with elements in the ration (1,85: 1:2,12), yield was received on 10,7-15,6 t/ha in comparison with yield 60,5 - 65,4 t/ha on doses N120P65K138 and N135P73K155. The content of nutritious elements in dry matter of cabbage changed in dependence on level of fertilizers application and their types at which the high yield was received. Maximum content of nitrogen 5% in cabbage head is noted at fertilizers application in dose N150P90K180 of ordinary fertilizers against the manure background in dose 60 t/ha. Replacement of ordinary forms of fertilizers to complex ones has promoted decrease of nitrogen content on 0,6-1,2% and improvement of quality of products. Removement of nitrogen changed considerably from 30,4 to 39,7 kg/10t production at application of mineral fertilizers system
