INFLUENCE OF BIO-FERTILIZERS (RHIZOBIA, MYCORRHIZAE) AND PHOSPHOROUS ON NODULATION SOME GROWTH CHARACTERISTICS OF BROAD BEAN (VICIA FABA. L)

Abstract

An experiment was conducted in the green house Soil Science and Water Resources/College of Agriculture and Forestry University of Mosul, during winter season 2011 to study the effect of Bio (Rhizobia, Mycorrhizea) and Phosphate (Super phosphate, Rock phosphate)fertilizers on Nodulation and some properties of Broad bean growth. Result showed that (Rhizobia+Mycorrhizea+S.P2) treatment significantly was increased in the plant height with increasing rate (55.34%) compared to the control. Also the (Mycorrhizea + R.P1) and (Mycorrhizea+R.P2) treatments gave significant increase in the fresh weight of shoots system with increasing rate (45.12 and 40.70%) respectively compared with the control. While (Mycorrhizea + R.P1 (gave high significant increasing in the number and dry weight of nodule with (223.30and 308.38%) respectively compared to the control. (Mycorrhizea + S.P2) and (Rhizobia +Mycorrhizea) treatments were achieved compared to the control. The highest content of total chlorophyll in plant was achieved in the (Mycorrhizea+R.P2)treatment which gave significant increase with increasing rate (9,9%) compared to the control.
