Management of sulphur for yield augmentation in rice (Oryza sativa) under rice fallow system

Sulphur (S) is ranked as 4th most essential nutrient after nitrogen, phosphorous and potassium which plays a vital role in crop production. Its uses have declined recent years. S-deficiency soils of Odisha has increased from 36% during 2008–09 to 44% 2018–19. A field experiment was conducted at farmers’ Ankurda village, Goindia block Dhenkanal district, for two years (2018–19 2019–20) order study the effect different sources sulphur rice (Oryza sativa L.) (cv. Swarna Sub 1) under mid-central table land zone Odisha. The RBD with 10 treatments 3 replications. Four (SSP, calcium sulphate, elemental S0 navaratna (20-20-0-13) were used methods, viz. basal top dressing rainy (kharif) season. mixture source formulated (CaSO4 + SSP) @1:1 ratio applied only. Among applied, highest biomass yield recorded spilt method ES followed as: ESo>mixture source>navaratna>SSP>gypsum. Due S fertilization, by 16% over control (T1). Spilt application fertilizer exerted beneficial on attributing character, higher grain straw yield, uptake, use efficiency harvest index, quality parameters B:C Sub-1 comparison fertilizers
