From May to November 2014, a research was carried out to study the soil fertility status of lowland paddy field differed in the cropping system in Paundi watershed, Nepal. A total of 20 soil samples were collected and analyzed, and a household survey was carried out to collect the information regarding soil fertility management practices being adopted along with crops yield. Average annual inputs of the organic manure, urea, Diammonium phosphate (DAP) and Muriate of potash (MoP) were 21 t ha-1, 143 kg ha-1, 116 kg ha-1 and 16 kg ha-1 respectively. Maize field received significantly higher amount of the organic manure, whereas the rice crop received the higher amount of the urea and DAP. Terrace riser slicing and the legume integrations were the other soil fertility management strategies being adopted by farmers. Soils were silt clay loam and were acidic. The soil organic matter in paddy field was low though the level was significantly higher in rice-rice cropping system than that of in rice-maize system. Most of the soils were low in the soil total nitrogen and available phosphorus. Potassium appeared to be low in the study area. Available zinc was found to be adequate in both types of the paddy field. The yield of the wet season rice, dry season rice and maize crop were 3.75, 2.0 and 2.6 t ha-1 respectively. Appropriate soil fertility management practices should be adopted to improve the soil fertility level in the study area.
