to study the effect of compost (7.5, 10.0 and 12.5 ton/fed) and seven treatments of stimulants i.e. control, seaweeds extract (300 ppm), amino acids (200 ppm), ascorbic acid (100 ppm), salicylic acid (50 ppm), active yeast (5 g/l) and Minia azotein (50 ml/plant), as well as their interaction on vegetative growth and flowering parameters of gladiolus plants. Data resulted that all compost levels increased vegetative growth parameters (leaf length, number of leaves/plant and leaves dry weight), flowering aspects (spike length, spike diameter, spike fresh weight, number of florets/plant, lower floret diameter and single floret fresh weight) comparing with control. Compost at 12.5 ton/fed was the most effective in this concern. All six used treatments of stimulant substances led to significant increase in all previous characters as compared to control, the maximum values were obtained by amino acids, followed by active yeast. The interaction treatments were significant with, the highest values recorded due to compost (12.5 ton/fed) in combination with either amino acids or active yeast.

to study the effect of compost (7.5, 10.0 and 12.5 ton/fed) and seven treatments of stimulatory substances i.e. control, seaweeds extract (300 ppm), amino acids (200 ppm), ascorbic acid (100 ppm), salicylic acid (50 ppm), active yeast (5 g/l) and Minia azotein (50 ml/plant), as well as, their interaction on corms and cormels productivity of gladiolus and some chemical composition constituents. The obtained results indicated that the three levels of compost significantly increased corm diameter, number of cormels/plant, fresh weights/plant, as well as, chemical composition (photosynthetic pigments and N, P and K%) as compared to control. The maximum values were obtained by using compost at 12.5 ton/fed. Treated plants with any of six used stimulatory treatments considerably increased corm and cormels productivity and chlorophyll a, b and carotenoids content, as well as, the percentage of N, P and K in the leaves. Minia azotein was the most effective than the other treatments in this concern the interaction treatments were obtained due to fertilizing gladiolus with compost at 12.5 ton/fed and inoculation of the soil with either Minia azotein or with the sprayed plants with active yeast.

A field experiment was carried out at the experimental farm of Fac. of Agric., Minia Univ. during two seasons (2012/2013 and 2013/2014) to study the effect of compost (0, 2.5, 5 and 7.5 ton/fed) and eight bio-stimulant treatments (salicylic acid (Sal.) at 100 and 200 ppm, ascorbic acid (Asc.) at 100 and 200 ppm, active yeast at 5 and 10 g/l, vit. E at 50 and 100 ppm and control) on growth and fruit yield production of cumin plants. The data showed that using 7.5 ton/fed compost significantly increased vegetative growth parameters (plant height, stem diameter, number of branches/plant and herb dry weight/plant) and yield and yield components characters (number of umbels/plant, fruit yield/plant and / weight of 1000 fruits) comparing with other treatments. Treating plants with Sal., Asc., active yeast and vit. E, each at two concentrations significantly increased vegetative growth parameters and yield and yield component characters comparing with control treatment, except Asc. at 100 ppm for weight of 1000 fruits during the first season. The best treatments were Sal. followed by Asc., then active yeast and vit. E, each at high concentrations in this concern.
