Abstract:
A field experiment was carried out during kharif, 2018 on sandy clay loam soils of dry land farm of S. V. Agricultural College, Tirupati, Acharya, N. G. Ranga Agricultural University. The experiment was laid out in randomized block design with ten phosphorus management practices and replicated thrice. Plant height, Dry matter production and yield was significantly influenced by the different phosphorus management practices. Application of 100 % recommended dose of phosphorus along with Arbuscular mycorrhizae (AM) @ 12.5 kg/ha and Phosphate Solubilizing Bacteria (PSB) @ 5 kg/ha (T₄) recorded significantly taller plants, higher dry matter production, green cob (14033 kg/ha) and green fodder yield (17950 kg/ha) in sweet corn. However, 75 % RDP + AM @ 12.5 kg/ha + PSB @ 5 kg/ha has given a remarkable green cob (13400 kg/ha) and green fodder yield (17210 kg/ha) along with a dry matter production which is in turn in parity with 100 % RDP + AM @ 12.5 kg/ha + PSB @ 5 kg/ha (T₄) at 60 DAS and at harvest.
