Effect of foliar application of vermiwash, bioferment and different methods of plant nutrition on morphological traits in sunflower

In order to study of Effect of foliar application of vermiwash, bioferment and different methods of plant nutrition on oil percentage in sunflower, this study was carried out in field of Payaam Nour Arak University in Markazi province in 2013. A factorial arrangement of treatment in a randomized complete block design with three replications was used. Nutrition methods [N1: 300 Kg ha-1 Urea (Control), N2: 50% of nutrition by Urea 50% of nutrition by FAM (15 ton ha-1), N3: 50% of nutrition by FAM 50% of nutrition by nitrogen fixation of phaseolus sp), N4: 50% of nutrition by Urea 50% of nutrition by nitrogen fixation of phaseolus sp) and plant bio-stimulants (B1: Foliar with wermiwash, N2: Foliar with enrich wermiwash, N3: Foliar with bioferment, N4: Foliar with effective microorganisms quail egg) were assigned in plots. Each sub plot consisted of 4 rows, 5 m long with 50 cm between rows space and 25 cm between plants on the rows. In this study characteristics such as: plant height, head diameter, wet biomass weight, weight of head, harvest index, number of grain per head and oil content were assessed. Results indicated that the effect of different levels of nutrition methods on the characteristics such as: plant height, head diameter, wet biomass weight, weight of head, and oil content were significant. Effect of plant bio-stimulants treatment on the characteristics such as: head diameter, wet biomass weight, harvest index, number of grain per head and oil content were significant, too. The maximum and minimum of oil content (35.64 and 30.99 %) were obtained with the (50% of nutrition by Urea 50% of nutrition by nitrogen fixation of phaseolus sp) and (50% of nutrition by Urea 50% of nutrition by animal manure) treatments, respectively. In the treatment of biostimulat as the most and least amount of oil content with an average 35.24 and 33.17 %, were spray of vermiwash and (effective microorganism quail Egg), respectively.
