Response of faba bean (Vicia faba L.) to rhizobium, VA-mycorrhizal and phosphorine inoculation understarter doses from nitrogen fertilization [electronic resource].

Includes references.

To study the effect of three nitrogen starter doses (0, 10 and 20 kg N/fed.) and inoculation with Rhizobium, (Rh), VA-mycorrhize (VA- M) and Phosphorine (Ph) and their interaction on seed yield and its components of faba baan, two field experiments were conducted at the Experimental Farm, Fac. of Agric. At Kafr ElSheikh, Tanta Univ., Egypt during the two successive winter seasons 1999/2000 and 2000/2001. A split plot design with four replicates was used in this study. The main results could be summarized as follows: 1- Increasing nitrogen starter doses up to 20 kg N/fed. markedly increased plant height at harvest, number of branches/plant, number of pods/plant, number of seeds/pod, number of seeds/plant, 100-seed weight, seed yield/plant, seed yield/fed. and seed protein content. Each increament of applied nitrogen as starter doses exhibited a significant increase in all estimated traits. 2- Significant increases in all traits under study were recorded by the inoculation treatments over the control. In general, inoculation with Rhizobium alone or combined with other biefertilizer was more effective in increasing seed yield and Its attributes as well as seed protein content. The highest value of all studied characters was observed for inoculation treatment with mixture of Rhizobium, VA- mycorrhize and Phosphorine together.
