Influence of nutrients accumulation by various levels of phosphorus and phosphorus solubilizing bacteria in summer groundnut


Author(s): Solanki KD, Sakarvadia HL and MP Purohit

Abstract: A field experiment was conducted on summer groundnut (var. GJG 31) at Junagadh Agricultural University, Junagadh during summer, 2018. The treatments comprising of different four levels of phosphorus viz., 0, 12.5, 25 and 50 kg ha-1 and four levels of phosphorus solubilizing bacteria (PSB) viz., 0, 1, 2 and 3 lit ha-1 in Factorial Randomized Block Design repeated thrice were tested in the experiment, in respect of content and uptake of nutrients like N, K, S, Fe, Mn, Zn and Cu at harvest and P at 30, 60 DAS and at harvest in pod & haulm and their total uptake by groundnut crop. Application of 50 kg P2O5 ha-1 significantly increased only the phosphorus content in pod and haulm at harvest and in plant at 30 and 60 DAS. Whereas, phosphorus application did not exert any significant effect on N, K, S, Fe, Mn, Zn and Cu content in pod and haulm. Application of 50 kg P2O5 ha-1 significantly increased the uptake of all the nutrients (N, P, K, S, Fe, Mn and Cu) by pod, haulm and its total uptake by the groundnut crop, except Zn uptake by pod and haulm. Application of PSB produced significantly favorable effect on phosphorus content in pod and haulm at harvest and in plant at 30 & 60 DAS of groundnut. While, PSB application did not exert any significant effect on N, K, S, Fe, Mn, Zn and Cu content in pod and haulm. Significantly higher values of all these parameters were observed with application of 3 lit PSB ha-1. Application of 3 lit PSB ha-1 also significantly increased the uptake of all the nutrients (N, P, K, S, Fe, Mn and Cu) by pod, haulm and its total uptake by the groundnut crop, except Zn uptake by pod and haulm.
