Abstract
Field experiment was conducted at Department of Agronomy, College of Agriculture, Dhule during Kharif 2019 to study the effect of pre and post emergence herbicides on soil chemical properties in sweet corn. The treatment of weedy check (T1) recorded significantly higher soil organic carbon of 5.51 g kg-1. There was no variation in the soil organic carbon content among the treatments of pre and post emergence application of herbicides. The soil organic carbon in all these treatments of pre and post emergence application of herbicides was in the range of 5.43 to 5.45 g kg-1. The periodical soil available N was significantly influenced at 7, 15, 21, 30 and 45 days after application due to application of pre and post emergence herbicides to sweet corn. At harvest of sweet corn, the application of halosulfuron-methyl @ 90 g ha-1 as post emergence recorded significantly higher soil available N (208 kg ha-1), available P (17.11 kg ha-1) and available K (333.33 kg ha-1). The treatment of weedy check (T1) recorded significantly lower soil available N (195.33 kg ha-1), available P (15.33 kg ha-1) and available K (306.44 kg ha-1).
