Effects of soil and foliar application of Zn fertilizer on yield and growth characteristics of bread wheat (Triticum aestivum L.) cultivars.

摘要

In order to investigate the role of Zn application (soil + foliar application) on growth traits, yield, its concentration and accumulation in wheat leaves and grains, two common cultivars of wheat namely Tajan and Nye 60 have been selected. Four Zn fertilizer levels including Zn0 (no zinc fertilizer), Zn1 (5 kg Zn/ha in soil + 300 g Zn/ha in foliar application), Zn2 (10 kg Zn/ha in soil + 600 g Zn/ha in foliar application) and Zn3 (15 kg Zn/ha in soil + 900 g Zn/ha in foliar application) both from ZnSO< sub>4 source have been applied in planting and booting stage in soil and as foliar application. Zn had increasing effects on grain yield, total dry matter, yield, 1000 grain weight, number of tiller, grain Zn content, flag leaf Zn content, plant height, number of node, protein content and grain Fe content. The number of tiller, grain Zn content and percentage of protein were higher in Tajan than Nye 60. On the otherhand, Nye 60 had higher grain yield and 1000 grain weight than Tajan, however, other measured traits showed no significant difference.
