Type: article
Abstract: A field experiment was carried out at Sakha Agricultural Research Station in 1998/99 and 1999/2000 seasons to study the effect of N-fertilization and inoculation with Rhizobium and Azotobacter on nodulation, N2-fixation and yield of Giza 51, Sinai 1 and Line 3693 lentil cultivars. Treatments of nitrogen zero and 15 kg/fed. (1 fed. = 0.42 ha) and four treatments of inoculation were used, uninoculated, inoculated with . Rhizobium, Azotobacter and' Rhitobium + Azotobacter . . The results indicated that, the new lentil line 3693, N-fertilization with starter dose (15 Kg·/feO.), and -mixed inoculation with Rhizobium and Azotobacter gave the highest number and dry weight of' nodules and dry weighVplant. The interactions effect between mixed inoculation with Rhizobium and Azotobacter with lentil line 3693 or N-fertilization gave the highest values of these traits. The two cultivars, Giza 51 and line 3693 superior to Sinai-1 cultivar in yield and yield components, in the two growing seasons. While, the data showed that insignificant responseto N-fertilization.on yield and its components. Mixed inoculation of Rhizopiurn .and Azotobacter significantly increased seed yield and all tested components.' Nitrogen seed content was increased by N-fertilization and bacterial inoculation. The interactions between lentil cultivars, N-fertilization and bacterial inoculation on yield and its components were not significant.
