Effect Gibberllic acid and super phosphate fertilizer on some growth characters of fenugreek plant Trigonella foenum – graecum L. Local varity

Abstract

An experiment was carried out by using pots (capacity 4 Kg soil/pot) inside the glasshouse of Biology Dept. College of Education (Ibn Al-Haitham) of University of Baghdad during the growing season 2010 – 2011, to know the effect of different concentrations of GA3 at (25 , 50 and 100) ppm and three levels of super phosphate fertilizer (0.25 , 0.50 , 1.00) gpot-1 that equal (83.33 , 166.66 and 333.32) kgh-1 on some growth components of fenugreek plant (local Varety), dry weight of plant on 1st sampling, number of branches, weight of pods, weight of seed in pod, weight of seeds (g) in plant. Factorial experiment within a completely randomized design (C. R. D.) with three replicates was adopted; means were compared by using the least significant difference at 0.05 probability level. Results showed that 50 ppm of GA3 with 0.50 gpot-1 of the fertilizer gave the highest values of the studied characters compared with other treatments.
