Abstract
Peanut plants use nitrogen sources from the atmosphere with the help of Rhizobium bacteria. Rhizobium was requiring P elements for root nodules formation. This study aims to determine the effects of the application of mycorrhizae at different levels that play an essential role in increasing P elemental uptake and rhizobia inoculants to improve N element fixation and root nodule formation. Rhizobia inoculant applications were allotted to main plots and levels of mycorrhizae to the subplots under each main plot. Three types of rhizobia applications viz., soaking (A1), spraying (A2), soaking and spraying (A3) and four levels of mycorrhizae doses viz., 0 g plant–1(M0), 10 g plant–1 (M1), 15 g plant–1 (M2), 20 g plant–1(M3). The results indicated that the application of Rhizobium at various doses of mycorrhizae together had a significant effect on plant height 70 d (A2M1 = 53.96 cm), leaf number 70 d (A1M3 = 42.75), leaf N content (A3M3 = 5.36 g 100 g–1), leaf P content (A3M3 = 0.418 g 100 g–1), leaf K content (A3M3 = 0.273 g 100 g), number of root nodules (A3M0 = 120), and weight of fresh pods plant (A1M3 = 33.67 g). That application can enhance root nodules and had increased NPK uptake.
