EFFECT OF SOIL AND FOLIAR APPLICATION OF NPK ON SEED QUALITY OF WHEAT

Afield experiment was conducted at the State Board for Agriculture Research Experimental Station, Abu- Ghraib during 2003-2004. The design was randomized complete block with three replications. The objectives were to study the effect of three levels of soil application of N P K fertilizer 0 (So); 160-80 and 120 (S1); and 320, 160-240 kg.ha(-1) plus eight treatments of foliar application of N P K control (FW), FN, FP, FK, FNP, FNK, FPK and FNPK. Applied foliar treatments were done at tillering, elongation and flowering stages. The concentrations of foliar spray were 1000N, 500P, 1000K mg. L-1, 2000N, 1000P, 2000K anti to 3000N, 1500P and 3000K mg. L-1. The results Showed that nitrogen, protein and glutenine or wheat seed increased in S1FNPK treatments by (467.3, 65.6, 67.6)% over the control treatment SoFw, respectively. Duplication of soil fertilizer did not caused significant differences between S1FNPK and S2FNPK for these parameters.
