The experiment was designed to evaluate the effect of levels of two types of
fertilizers: organic (farmyard) manure (O0= 0, O1= 200, O2= 400 g/m2 ) and NPK fertilizer
(15:15:15) (F0= 0, F1= 80, F2= 120 g/m2 ) on decorative features of Tulip Frenged, Tulipa
gesneriana. All the flowering and bulb quality attributes were significantly influenced by the
addition of farmyard manure and NPK to the soil. The results indicated that the farmyard
manure FYM added to the soil increased the spike and flower diameter and reduced the
number of days of flower color show, in comparison, the plants grown without farmyard
manure and chemical fertilizer NPK. the highest flower diameter was recorded when the
FYM2 with chemical fertilizer NPK F1 and F2 were mixed and added to the soil together. The
results showed that the bulbs, which were planted in soil containing farmyard manure and NPK
chemical fertilizer, shortened the flower days to show color and open. NPK applications
increased the weight and diameter of bulbs.
