اثر تراکم و محلول‌پاشی نانو کودهای آهن و روی بر عملکرد و اجزای عملکرد گیاه دارویی کاسنی(Cichorium intybus L.)

In order to study the effect of different plant density and foliar application of nano fertilizers iron and zinc on the biological yield, seed yield and components yield of chicory a field experiment was conducted in research station of Bu-Ali Sina University on 2013 growing season. A factorial experiment based on randomized completely block design was used with three replications. Plant density included three levels 10, 15 and 20 plant m-2 and foliar application of nano fertilizers were in four levels, iron nano fertilizer, zinc nano fertilizer, iron nano fertilizer + zinc nano fertilizer and control. The results indicated that interaction between treatments on all traits were significant. The highest biological yield and seed yield obtained with 10 plant m-2 and simultaneously foliar application nano fertilizers iron + zinc. The foliar application of nano fertilizers iron and zinc in densities 10, 15 and 20 plant m-2 caused to increasing 42, 33 and 26 percent on seed yield and increasing 41, 33.5 and 21 percent on biological yield than control respectively.
