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.

An experiment entitled “Response of organic manures and varieties on growth and yield of cowpea at Bharatpur, Chitwan” was conducted in Agronomy farm of Nepal Polytechnic Institute during spring season 2022. The experiment was conducted in two factorial Randomized Complete Block Design with three replications and ten treatments. The treatments were set as two variety: V1: Surya and V2: Prakash as factor A and 20 kg N from different sources of organic manures (OM): OM1: FYM (0.5%N) 4 t ha-1, OM2: Poultry manure (5%N) 0.4t ha-1, OM3: Vermicompost (2.5% N) 0.8 t ha-1, OM4: Suchit biofertilizer (8.72% N) 0.23 t ha-1, OM5: Mustard oil cake (5.2% N) 0.39 t ha-1 as factor B. The main objective of the experiment was to find out the best variety and good organic manure for getting better yield of cowpea under rainfed condition. Results revealed that the variety Surya produced the highest grain yield (1.01 t ha-1) followed by Prakash (0.91 t ha-1). In case of organic manures, the highest grain yield (1.37 t ha-1) was obtained in 4 t ha-1 of FYM applied plot. The interaction effect between variety and organic manures showed that the variety Surya along with 4 t ha-1 FYM showed maximum grain yield (1.41 t ha-1). From this experiment, it is concluded that the use of variety Surya with 4 tons of FYM ha-1 gives the highest productivity with better economic return compared to all other treatments.

The study about performance of different varieties and plant geometry on productivity of cowpea (Vigna unguiculata L.) was carried at Bharatpur, Chitwan from duration of February to May. The effect of two variety (Prakash and Surya) and four spacing (60 cm × 10 cm, 60 cm × 15 cm, 60 cm × 20 cm and 60 cm × 25 cm) were studied using two factor Randomized Complete Block Design (RCBD) having eight treatment replicated three times consisting of 24 plots. The main objective of the research is to find out the best variety and appropriate spacing for getting higher yield of cowpea. Results revealed that variety Surya showed the highest grain yield (1.25 t/ha) followed by Prakash (1.06 t/ha). Whereas, in case of spacing, the highest grain yield was obtained in 60 cm × 15 cm (1.33 t/ha).Similarly in combine treatment; the highest grain yield (1.47 t/ha) was obtained in combination of Surya and 60 cm × 15 cm. From experiment it is concluded, the combination of Surya and 60 cm × 15 cm gives highest productivity compared to all other treatments at terai region of Nepal.
