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. The soil microbial status was found to be significantly influenced by different levels and sources of phosphorus. Application of 100% RDPalong with AM @ 12.5 kg ha-1 and PSB@ 5 kg ha-1 (T4) recorded significantly higher fungi and actinomycetes population in sweet corn. The maximum bacterial count was registered with 50% RDP + AM @ 12.5 kg ha-1 + PSB @ 5 kg ha-1 (T10), which was closely followed by that with 50% RDP + PSB @ 5 kg ha-1 (T9). Among the different combinations of phosphorus sources tried, application of 100% RDP + AM @ 12.5 kg ha-1 + PSB @ 5 kg ha-1 (T4) recorded the maximum leaf area index and leaf area duration at all the stages of sweet corn.Combined application of 100% RDP + AM @ 12.5 kg ha-1+ PSB @ 5 kg ha-1 to sweet corn is the most efficient integrated phosphorus management practice for better crop growth and soil microbial status.
