Abstracts |
Field experiments were conducted in Ludhiana, Punjab, India for two consecutive years (rabi 1995-96 and 1996-97) to study the effect of various levels of N (0, 25, 50 and 75 kg ha-1) with Rhizobium alone and in combination with vesicular arbuscular mycorrhiza (VAM) on nitrogen fixation, VAM colonization and grain yield in chickpea cv. PBG-1. Maximum number and dry weight of nodules and nitrogenase activity were found at 50 kg N ha-1 in dual inoculated treatments. Nodulation and nitrogenase activity were inhibited at 75 kg N ha-1. However, maximum percentage of mycorrhizal colonization and grain yield were recorded at 75 kg N ha-1. Thus, higher level of N might facilitate VAM colonization and increased grain yield of chickpea in the presence of Rhizobium inoculation. |
