Effect of zinc sulfate and plant density on quantitative and qualitative yield of Triticale in dryland condition

This experiment to study aim effect of different levels of plant density and zinc sulfate on quantitative yield of triticale and its rule on human and livestock feed was conducted at deh-sefid village of Khorramabad¡ in cropping year 2009- 2010 (November 13¡ 2009). 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 desing with three replications. Results showed that interaction of density and different levels of zinc sulfate treatments on variables¡ such straw yield¡ economical yield (seed) and biological yield (1% prob) as harvest index (5% prob) were affected significantly. The higher production. The highest straw and seed yield (12810¡ 12770 kg / ha) was observed in200 and 300 plant / m2 to using 60 kg/ha zinc sulfate (d2f3 and d1 3)¡ biologic yield (22303 kg / ha) and harvest index (44.53%) was obtained from treatment 300 plant / m2) to using 40 kg / ha zinc sulfate (d2f2). Thus was concluded that minum and optimum of plant density (200 and 300 plant / m2) increased yield to ratio using fertilizer (40 and 60 kg / ha)¡ therefor¡ can proposed using fertilizer to further yield. The highest and lowest percent protein were obtained from treatments d3f2 (400 plant / m2. 40 kg / ha zinc sulfate ) and d2f2 (300 plant / m2 .40 kg / ha zinc sulfate) equal to 9.8 and 7.08 % respectively.
