Description A field experiment consisting of three crop establishment methods and five zinc fertilization treatments was conducted in a split-plot design with three replications at Varanasi during Kharif season of 2016-17 and 2017-18. Soil samples after harvesting of rice were collected and analyzed for available nitrogen (N), phosphorus (P), potash (K), and zinc (Zn); organic carbon (OC) and soil microbial biomass carbon (SMBC). Results revealed that zero till-direct seeded rice observed higher available N, P, K and Zn, OC and SMBC. With respect to Zn fertilization, 3 kg Zn ha-1 foliar application proved superior for available N, P and K. However, for available Zn, OC and SMBC, 6 kg Zn ha-1 basal application was adjudged better. It is concluded that zero till-direct seeded rice and basal application of 6 kg Zn ha-1 proved superior for available Zn, OC and SMBC under direct seeded rice.
