This study was carried out in Harrabot village of Tarkughat VDC, Paundi and Majuwa village of Sundarbazar Municipality of Lamjung district during 2015/2016. Thirty households (10 HH from each village) who were involved in seed production were purposively selected for survey. The respondents’ knowledge was gathered through focus group discussions and household surveys, using a pretested semi-structured questionnaire. Seed routine test was carried out in the Agronomy lab of Lamjung Campus. Results revealed that the dominant features of farming in the study areas were small land holdings, fragmented and sloping land with rainfall-dependent farming. Land distribution pattern was 12.93% marginal land, 16.35% upland and 70.72% irrigated lowland. Farmers grew rice, maize, mustard and pulses as major crops and fruits, vegetables, potato and flowers as minor crops. Major cropping pattern were Rice-Mustard-Maize, Maize-Rice-Fallow, Rice-Fallow-Rice etc. Nutrient-poor soils, low pH, farmers' poor access to inorganic fertilizers, soil-depleting cropping patterns, lack of technical knowledge on crop management, soil erosion and degradation are major challenges. Insects, diseases and weeds were major biotic constraints, while lack of irrigation, drought and lack of technical support were major abiotic constraints of rice production. Sukhadhan-2, Sukhadhan-3, Sukhadhan-4, Sukhadhan-5 and Sukhadhan-6 were planted in rain-fed lowland, whereas Ramdhan, Sunaulo sugandha, Loktantra, Sabitri and Makwanpur-1 were grown in irrigated lowland. Seed producers used 39.07% of the land for seed production with 4.78 tons ha-1 of seed productivity. Most of their produced seed was send to Sundar Seed Coop Ltd., Paudibazar, while some seed were stored in their home by using local containers such as earthen pots, plastic drums, metal bins, Dali, Kotho, Bhakari etc. The tested seed quality parameter in the lab showed that the average moisture, purity and germination percentage of the seed samples were 13.87%, 94.13% and 96.72%, respectively.
