Effect of different levels of urea and superphosphate fertilizers on some morphological and physiological characters of fenugreek plant (Trigonella foenum-graecum L.)

Abstract

An experiment was conducted using pots (capacity of 4 kg soil/pot) in the glasshouse of Biology Dept. College of Education (Ibn Al-Haitham) University of Baghdad during 2008-2009 growing season, in order to determine the effect of different levels of urea fertilizer (Zero,0.1,0.2,0.4 gm/4 kg soil in pot) these equal to (Zero,100,200,400 kg/ha) and different levels of superphosphate fertilizer (Zero,0.1,0.2 gm/4kg soil in pot), these equal to (Zero,100,200 kg/ ha) on some morphological and physiological characteristics of fenugreek plant . This experiment was conducted using Completely Randomized Design (C.R.D) with three replications and the experiment included (36) pots. Results indicated clear increase in all studied characteristics with increasing urea and superphosphate levels added to pots. The levels (400 kg urea/ha and 200 kg superphosphate/ha) were best giving high values of these characteristics (dry matter weight, absolute growth rate, biomass duration and total chlorophyll content) compared with other levels of treatment.
