Abstract From the seed exudates of Vicia faba L. (cv. Muchamiel) the flavonoid aglycones 7,3′,4′-trihydroxyflavone, 7,4′-dihydroxyflavone, quercetin and kaempferol, and the flavonoid glycosides quercetin 7-glucoside and kaempferol 7-glucoside were identified. This is the first time that the flavonoids present in Vicia seed exudates are described. The study of the flavonoids present in legume seed and root exudates is especially important since these substances may act as chemical signals activating or inhibiting Rhizobium nodulation genes. In fact, the activating effect on Rhizobium nod genes of 7,3′,4′-trihydroxyflavone and 7,3′-dihydroxyflavone has previously been reported. It is remarkable, that these compounds increase dramatically in mature pods, and these tissues might have an additional ecological role in the signal function on Rhizobium to establish the symbiosis

Rhizobium Nodulation

Olive processing waste (OPW) is a by-product of olive oil production. Most of the studies about olive processing waste are carried-out in cotton, sunflower, wheat etc. However, there is little research performed on the effects of OPW on legumes. Therefore, the effect of OPW on growth of fababean and Rhizobium bacteria was studied in this research. It was used in doses of 0 (control), 18, 30 and 42 grams per pot, which is equivalent to doses of 3, 5 and 7 kg m-2. Increasing concentration of OPW improved the root fresh weight, nodule area, nodule diameter, root nodules scale value and the number of Rhizobium in one gram nodules. The results showed that the optimum OPW dose was 30 g pot-1 according to plant growth, nodules and Rhizobium. It was concluded that the OPW concentrations of 3% and it’s below can be used for fababean growing.

Rhizobium Nodulation

Two field experiments were carried out during two consecutive rabi seasons of 2002-03 and 2003-2004 at Farming System Research Site, Chabbish Nagar, Rajshahi (AEZ 11) with a view to assessing the effect of Rhizobium inoculation on four varieties of chickpea viz., BARI Chola-3, BARI Chola-4, BARI Chola-5 and BART Chola-6. Each variety was tested with and without Rhizobium inoculation. Each plot received basal application of 22 kg P/ha as TSP, 42 kg K/ha as MOP, 20 kg S/ha as gypsum and 5 kg Zn/ha as zinc oxide. Peat based rhizohial inoculurn (Rhizohium strain RCa-220) @ 1.5 kg/ha was used for seed inoculation. Inoculated plants gave significantly higher nodule number, nodule weight, stover yield and seed yield compared to uninoculated plants. Among four varieties, BARI Chola-3 produced the highest nodule number, nodule weight and stover yield, while the highest yield was obtained from BARI Chola-4.
