Effect of some mineral fertilizers on growth and productivity of wheat

Two field experiments were carried out at Ismailia Experimental Station, Agric. Res. Center, Ismailia governorate, during 2007/2008 and 2008/2009 seasons to study the influence of spraying magnesium sulphate (MgS04), copper sulphate (CuS04) and their interaction on growth, yield and yield components as well as nutrients status of wheat (Triticum aestivum L.) cv. Sakha 94. Nine treatments were applied: two levels of magnesium sulphate (3.36 and 6.72 kg/fed.), two levels of copper sulphate (0.84 and 1.68 kg/fed.) and four combined treatments (MgS04 + CuS04), in addition to control treatment (water spray) by using randomized complete block design. Results showed positive significant effects on plant height (cm), tillers number/m², spike number/m², spike length (cm), spike weight (g), grains number/spike, grains weight/spike (g), 1000-grain weight (g), grain yield ardab/fed. and straw yield were achieved by spraying the magnesium sulphate and copper sulphate treatments. However, the highest marked increment in grain yield was obtained by spraying plants with the highest CuS04 level (1.68 kg CuSo4/fed.), while spraying the lowest level of CuS04 (0.84 kg CuSo4/fed.) gave the highest straw yield. On the other hand, combination treatment of 6.72 kg MgS04 + 1.68 kg CuS04/fed. showed the highest grain-protein content, N, Mg, Cu and Zn. Moreover, spraying wheat plants with the low CuSo4 level (0.84 kg/fed.) gave the highest grain carbohydrate.
