Abstract:
Organic manure applications can affect the soil chemical properties. In a rice cultivation there are wide variations in the soil chemical characteristics throughout the crop cycle. The present study was conducted to study the impact of different manures on soil phosphorus, potassium, DTPA Zn and Fe in a rice (basmati) during 2018 and 2019. The treatments were T1-Control (No application); T2-Farm Yard Manure (FYM) (100% N); T3-Vermicompost, VC (100% N); T4 - FYM (50% N) + VC (50% N); T5-FYM (50% N) + Poultry manure, PM (50% N); T6-FYM (50% N) + Neem cake, NC (50% N); T7-VC (50% N) + PM `(50% N) and T8-VC (50% N) + NC (50% N). Available phosphorus and potassium were significantly affected by manure application in comparison to control, where no manures were applied during both the years. Treatment VC+PM significantly increased available phosphorus and potassium.
