Abstract
An experiment was conducted on growing season of 2011 ـ 2012 of two soils to study the effect four levels organic matter (0, 2, 4, 6) ton.ha-1 and four levels of phosphor (0, 80, 160, 240) kg.ha-1 and their interaction on the growth of fenugreek.The results showed that the use of higher levels of organic matter and phosphor fertilizer and their interactions caused a significant effect on yield by increasing the plant height, number of branches, yield per one plant and pods per plant. interaction effect of organic matter and phosphor fertilizer at higher concentration was more significant than each factor alone. Organic matter treatment at a rate of (6) ton.ha-1 with (240) kg P. ha-1 gave an increase in some of the charactes in both soils. first soil appeared a response for fertilizer of all levels studied compared with second soil
