Effect of Plant Density and Different Levels of Zinc Sulfate on Quantitative Yield of Triticale in Dry Land Conditions

This experiment was conducted to study the effect of different levels of plant density and zinc sulfate on quantitative yield of triticale at Deh-Sefid village of Khorramabad, in cropping year 2009- 2010. The application of three levels of zinc sulfate (Control, 40 and 60 kg / ha) and three plant densities (200, 300 and 400 plant / m2) were combined factorially based on the randomized complete block design with three replications. Results showed that reciprocal effects of density and different levels of zinc sulfate treatments on variables, such as straw weight, economical yield (seed), and biological yield (1% probability),and also harvest index (5% probability) were affected significantly. The highest straw weight (12810, 12770 kg / ha) was observed in 200 and 300 plant / m2 using 60 kg/ha zinc sulfate (d2f3 and d1f3). The highest biologic yield (22303 kg / ha) and harvest index (44.53%)and seed yield (9933 kg / ha) was obtained from treatment 300 plant / m2) to using 40 kg / ha zinc sulfate (d2f2). Thus was concluded that the minimum and average of plant density (200 and 300 plant / m2) increased yield according to the more use of fertilizer (40 and 60 kg / ha).
