Responses of yield and N use of spring sown crops to N fertilization, with special reference to the use of plant growth regulators	1999	18	.pdf	application/pdf	9045	402	75	PGR use showed negative response to N yields (3 to 12 kg ha-1) at N rates of 30–120 kg ha-1 in 1995, with the grain yield decrease. PGR use increased N yields only at the N rate of 120 kg ha-1, in 1994 (i.e., 3 kg ha-1 )	cache/afs-5639.pdf	txt/afs-5639.txt
