Effect of fly ash, organic manure and fertilizers on nitrogen, phosphorus and potassium content in grain and straw in rice-wheat cropping system in Alfisols and Vertisols


Author(s): LK Ramteke and SS Sengar

Abstract: Field experiment was conducted under Alfisols at KVK, Farm Katghora, Korba and Vertisols at Instructional Farm Indira Gandhi Krishi Vishwavidyalaya, Raipur during 2011 and 2012.To assess the effect of different doses of fly ash alone or in combination with manure and fertilizers in rice –wheat cropping system with Sixteen treatments (i.e. T1-Control, T2- 10 t FA ha-1, T3-20 t FA ha-1 T4-STCR (based fertilizer recommendation), T5-75% NPK ha-1, T6-100% NPK (100:60:40), T7-75% NPK ha-1+ 10 t FA ha-1, T8-75%NPK ha-1 + 20 t FA ha-1, T9-100% NPK ha-1+ 10 t FA ha-1, T10-100% NPK ha-1 + 20 t FA ha-1, T11-75% NPK ha-1+ 5 t FYM ha-1, T12-100% NPK ha-1 +5 t FYM ha-1, T13- 75% NPK ha-1 + 5 t FYM +10 t FA, T14- 75% NPK ha-1 + 5 t FYM +20 t FA ha-1, T15-100% NPK ha-1 +5 t FYM+10 t FA ha-1 and T16- 100% NPK ha-1 +5 t FYM+20 t FA ha-1) under Split Plot Design with factorial arrangment of crop and soil in main plot and treatment in sub plot. The nitrogen content significantly increases in grain and straw and treatmentT16 recorded highest N content and lowest in T1. The phosphorus increases in both the crops under Vertisol whereas higher phosphorus content in straw was recorded in rice under Alfisol and wheat under Vertisol. Interaction of crops x soil x treatment is significantly significantly influenced due to application of fly ash alone or in combination with organic manure and fertilizers. Potassium content in grain and straw was significantly increases in rice and wheat. Treatment, T16 recorded highest potassium content in grain whereas highest potassium content in straw was recorded in T12 and lowest potassium content recorded in T1.
