The effect of fermented pig manure processed on a bed of wooden sawdust and fermented for seven days by larvae of house fly on the yield parameters of maize and sunflower have been investigated on Haplic Luvisol in the pot trial realized in vegetative cage placed on the territory of Slovak Agricultural University in Nitra. Haplic Luvisol used in the experiment had medium supply of Nmin, suitable content of available P and high content of available K and Mg. The achieved results showed that application of fermented pig manure resulted in significantly greater stem thickness in both crops in the first third to half of growing season. Graduated rates of fermented manure more positively influenced maize grain yield than sunflower one in comparison to unfertilized control treatment. They significantly increased oil content in achenes and insignificantly affected content of starch in maize grain. Within the framework of all examined treatments the highest content of starch in maize grain and the highest content of oil in sunflower achenes were found out in treatment where 8 t per ha of dry manure was applied. The lowest yield of maize grain and sunflower achenes were obtained in unfertilized treatmen tand the highest ones in treatment with mineral NPK fertilizers application.
