Influence of various bio-fertilizers on the growth and yield of ground nut, arachis hypogeae l.

The peanut or ground nut (Arachis hypogeae L.) is a species in the legume or bean family (Fabaceae).The present study was carried out to study the effect of different bio-fertilizers on the growth and yield of ground nut plant. The bio-fertilizers used were Azospirillum, panchagavya, VAM fungi and a mixture of these three fertilizers. Control plant was maintained without any fertilizer application.In Arachis, the germination percentage was higher when the mixture of fertilizers was used. The shoot length, root length, fresh weight and dry weight were found to be maximum in either VAM treated plants or the plants treated with the mixture of fertilizers.The yield was more in Azospirillum treated plants. In case of nodules, in the early stages of growth, more nodules were formed in the Azospirillum treated plants. In later stages, Panchagavya treated plants showed more nodule formation.
