Abstract: A field study was conducted during kharif, 2017 to find out the optimum dose, time and method of application of MgSO4 for growth and yield enhancement in direct seeded rice.Results revealed that MgSO4 application had significant influence on yield attributes, yield and economics of direct seeded rice. Application of MgSO4 @ 40 kg ha-1 in two equal splits at 20 and 40 DAS (T6) registered the highest grain yield and was statistically comparable with the application of MgSO4 @ 20 kg ha-1 at 20 DAS along with foliar spray of 1 % MgSO4 at 40 DAS (T9), MgSO4 @ 20 kg ha-1in two equal splits at 20 and 40 DAS (T4) and MgSO4 @ 10 kg ha-1 at 20 DAS along with foliar spray of 2% MgSO4 at 40 DAS (T10). Split application was found to be superior and MgSO4 @ 40 kg ha-1 in two equal splits at 20 and 40 DAS registered the highest grain yield and B:C ratio. Application of MgSO4 @ 40 kg ha-1 in two equal splits at 20 and 40 DAS can be given as recommendation for farmers for getting higher grain yield and net income.
