The analysis of influence of separate and complex use of liquid nitric fertilizer mixture of carbamide and ammonium saltpeter with plant protection means on winter triticosecale crop capacity and seed quality is shown. The economic effectiveness of investigated methods is calculated. Application of plant growth regulator Epin on the background N19P70K100 + N50 + N30 CAS + REX T (0,6 l/ha) has raised productivity of grain of winter triticosecale on 4,2 c/ha. At complex application of Epin with CAS and Rex T the productivity of grain has made 64,1 and 64,3 c/ha accordingly, that is above in comparison with background variant on 4,6 and 4,8 c/ha. Both at separate and complex application of Epin with Rex T in comparison with the background N19P70K100 + N50 + N30 CAS + REX T (0,6 l/ha) the content of crude fiber in grain of winter triticosecale has increased on 1,0%, and output of crude fiber - on 1,2 c/ha and 1,3 c/h accordingly. At complex application of Rex T with CAS in comparison with separate on the background N19P70K100 + N50 + N30 CAS productivity of grain has increased on 1,8 c/ha, net profit - on 43,86 thousand rub/ha, profitability - on 15%. The highest crops on average for the period of 2005-2006 (64,3 c/ha), the raw protein 8,9 c/ha, the net profit of 313,68 thousand rub/ha and profitability 89% are gained with the combined usage of Rex T with Epin on the background of N19P70K100 + N50 + N30 CAS
