In the wetland areas, there is an ample scope of improvement with respect to productivity and sustainability of agricultural production offered by diversification and intensification of cropping systems. The key of success may be rested on the choices of efficient cropping systems and integrated assessment of various cropping systems in the wetland ecology. To evaluate five new cropping systems in North Bihar, a field experiment was conducted at the Research Farm of ICAR Research Complex for Eastern Region, Research Centre for Makhana, Darbhanga (Bihar) on a silty clay loam soil (Inceptisol) during 2011 and 2012. The experiment was laid out in a Randomized Block Design replicated thrice. The plot size under each cropping system was kept 30 X 20 m. Nutrient uptake and productivity generally increased with increasing cropping intensity. Positive residual effects of makhana (Gorgon nut) and barseem (Egyptian clover) were observed on improvement of soil properties such as available nitrogen (N), available phosphorus (P) and available potassium (K). Makhana-barseem cropping system was observed to add the highest amount of available nitrogen (35.00 kg/ha) and available phosphorus (20.70 kg/ha) to the soil, while, the maximum addition of available potassium was made by makhana-wheat cropping system (30.00 kg/ha). In terms of nutrient uptake, makhana-barseem cropping system was found to be recorded the highest remover of nitrogen (382 kg/ha) and potassium (205 kg/ha) while the highest removal of phosphorus from the soil system was recorded by makhana-water chestnut cropping system (89 kg/ha). Among makhana inclusive systems, ranking in terms of total productivity followed the order of makhana-barseem> makhana-wheat> makhana-rice> makhana-water chestnut.
