In this research, impact of different fertilizers on seed germination and seed growth of Sunflower (Helianthus annuus L.) was determined in year 2012. In the study, different doses of DAP, Urea and farm yard manure (FYM) were employed on experimental trials conducting in Randomized Complete Block Design (RCBD) in campus experiment grids. Highest germination rate was determined for Urea (87.5%) and followed by FYM (85%). For growth parameters Urea depicted maximum rate of shoot length (34.62 ± 0.15) at 30 days and for manure it’s was 31.70 ± 0.22. After 30 days, root length was 12.88 ± 0.23 and 16.10 ± 0.43 after 60 days. Number of leaves were Urea 10.37 ± 0.37 and in DAP number of leaves were 8.50 ± 0.54. In plant samples, fresh weight (FW) of was highest 18.0 ± 0.21 at 30 days and 60 days its FW was 27.67* ± 0.29. Dry weight (DW) of leaves was highest (4.03 ± 0.07) and least in control sample (3.10 ± 0.09). FW of roots was found highest in Urea and followed by FYM (43.00 ± 0.86), while DW of roots was maximum in Urea fed sample (10.80 ± 0.23). These results depicted that urea is best fertilizer for germination of seedlings of sunflower and second one is FYM fertilizer. The vegetative growth (shoot, root and leave length) was highest in experimental plots of in urea fertilizer. This research presents that different combinations of fertilizers may produce better results and further research is required.
