The experiment was conducted at Bihar Agricultural University, Sabour. This experiment consisting of nine treatments under rice establishment techniques viz., - Zero tillage (T1), Permanent bed (T2)and Conventional Tillage (T3) and Sub-plot Rice based systems ricewheat (S1) rice- maize (S2) and rice- lentil (S3).The paper focuses on conservation agriculture (CA), defined as minimum soil disturbance (NT) and permanent soil cover combined with rotations, as a more sustainable cultivation system for the future. The paper then describes the benefits of CA, a suggested improvement on CT, where NT, mulch and rotations significantly improve soil micronutrient properties. | Efect of establishment techniques and cropping systems on transformation of zinc in alluvial soil under conservation agriculture
