Fenugreek( Trigonella foenum –graecum L.) Effect of urea and supersphate Fertilizers their interacation on some yield characteristics of plant fenugreek ( Trigonella foenum – graecum L.)

Abstract

An experiment was conducted to study the effect of urea, superphosphate and their interacation on some yield components of fenugreek plant in the green house of Biology Department ,College of Education (Ibn Al-Haithum),University of Baghdad, the growing season of (2008-2009) in pots with 5 kg soil per pot. Four levels of urea (0, 0.25, 0.50 and 1.00) g/pot, equivalent to (0, 100, 200 and 400) kg urea/ha were used. The first round of urea was added before planting and the second after 40 days of sowing. Also three levels of superphosphate fertilizer (0 and 0.25 and 0.50) g/pot, equivalent to (0, 100 and 200) kg/ha were added at once before planting. Results showed that, the level of urea fertilizer, 400 kg/ha and 200 kg superphosphate/ha have led to a significant increase in the yield, number of pods/plant, dry weight of pods and the number of seeds/Pod.
