Influence of Organic Manure and Chemical Fertilization on Flowering and Yield Bulbs of Tulip Frenged, Tulipa gesneriana L.

Abstract

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.
