| Abstract | ||||
| WO FIELD experiments were conducted at the Agricultural …...Research Farm of the Higher Institute for Agriculture Co-operation during the two successive seasons of 2008 and 2009. These experiments aimed to study the effect of inoculation with Bradyrhizobium spp. either alone or in combination with (Pseudomonas fluorescens) on yield and some yield components under different levels of compost using drip irrigation system. Results showed that plants inoculated with Bradyrhizobium spp. only or in combination with rhizobacteria exhibited significant increases in pod yield and some yield components as compared with the uninoculated plants. The response of groundnut, yield and yield components to elevating the organic fertilizer rate was positively significant, higher rate of compost 15-ton/fed (1hectare= 2.4 feddan) showed higher values of all tested traits in both seasons. Spraying groundnut plants with humex increased significantly all tested traits compared with those without humex in both seasons. The effect of the first and second orders interactions on yield and yield components were significant. | ||||
