| Abstract | ||||
| A field experiment was conducted at Nursery of Ornamental Plants, Fac. Agric., Minia Univ. during 2013/2014 and 2014/2015 to investigate the effect of NPK (0, 50, 75 and 100% of recommended dose) and biofertilizers (phosphorein and/or E.M.) on corm and cormels productivity, as well as, chemical constituents of gladiolus cv. White Prosperity. The obtained results indicated that, corm diameter, corm dry weight, number of cormels/plant, cormels dry weight/plant, as well as, chemical constituents (N, P, K and total sugars % in corms and total chlorophyll in leaves) were significantly increased with all levels of NPK in comparison with control. The highest values were obtained with NPK 100%. All biofertilizer treatments significantly increased corm and cormels productivity, as well as, either chemical constituents in comparison with the control. Phosphorein + E.M. was more effective in this concern. The interaction treatments were significant with the highest values being obtained due to NPK 75% in combination with phosphorein + effective microorganisms (E.M.). | ||||
