The effect of bio, organic and mineral fertilization on productivity of sunflower seed and oil yields [electronic resource]. دراسة تأثير التسميد العضوى والحيوى والمعدنى على إنتاجية بذرة وزيت دوار الشمس. P. 1013-1028. Includes references. Two field experiments were conducted out at the experimental farm of Sakha agricultural research station, Kafr El-Sheikh, the experiments were conducted to study the effect of bio, organic and mineral fertilizers on seed and oil yields of sunflower through inoculation with biological nitrogen fixation (BNF) as a bacteria in form of (rhizobacterine or microbine inoculation), farm yard manure.(FYM) as organic source at rate of 20 and 30 m3 /fed.and mineral nitrogen fertilizer. A randomized complete block design with four replication was used. The obtained results could be summarized as follows: The bio, organic, mineral fertilizers and their combinations significantly affected growth analysis and som growth attributes such (dry matter accumulation Iplant and leaf area index), some agronomic characters such (stem diameter, head diameter and plant height) as well as yeild and its components such (100 seed weight, seed yeild /fed., oil percentage and oil yeild) in 2007 and 2008 seasons. Application of organic manure at the rate of 30 m3 /fed. FYM with 30 kgN/fed. as mineral fertilizers recorded the hieghest values of dry matter accumulation /plant, leaf area index, stem diameter, head diameter, plant height, 100 seed weight, seed oil content as well as seed and oil yeilds Ifed. Sunflower plants, which received 20 or 30 m3 FYM with biofertilizers as mixture of Microbin and Rizobacterine were among those having great dry matter accumulation Iplant, leaf area index, stem diameter, head diameter, plant height, 100 seed weight, seed oil content as well as seed and oil yeilds /fed. compared with those received 30 Kg N/fed. In both seasons. - Application of FYM alone at the rate of 20 or 30 m3 was less effect on growth analysis and growth. attributes, agronomic characters as well as yeild and its components than applying mineral nitrogen alone or combined with them.
