A review on the community based maize seed production and technology dissemination in Nepal was made in 2009 to know the seed production situation and technology dissemination approaches. Twenty three open pollinated maize varieties and one hybrid were released by the Nepal Agricultural Research Council (NARC) up to 2009. A number of stakeholders were involved on improved technologies dissemination, seed production and marketing. Approaches for technology dissemination include district seed self sufficiency program (DISSPRO) and community based seed production (CBSP) program. About 4500 ton of cereal seeds annually has been producing from these approaches. Approach include subsidies on source seeds, creation of revolving funds, group/co-operative formation, their mobilization for participatory varietal selection (PVS), demonstrations, training, informal research and development (IRD) kit distribution and exchange visits. In community level, activities such as community based seed production approaches, particiapatory technology development, verification and dissemination for sustainable seed production and marketing has been taken place.

Seed production of farmers preferred improved maize varieties under community based seed production(CBSP) group initiated in the hills of Nepal under Hill Maize Research Project in 2000. Trained members of the community group produce improved seeds identified through participatory varietal selection procedures. Despite quantum jump in maize seed production, 14 tons by 7 CBSP groups in 2000 to 1,036 tons by 207 groups in 2012, seed marketing remained one of the challenges in HMRP districts. Main objective of this study was to analyze maize seed production trend and presowing seed contracts in hill districts under HMRP. Linear regression model showed seed production trend over the period 2000 to 2012 highly significant. Annual compounded growth rate of seed during the same period was estimated to be 34.36%. Pre-sowing seed contract in cereal crops in the hills of Nepal is a new initiative of HMRP IV. Analysis showed 63 formal contracts were signed for 170.45 tons of improved maize seed between 50 CBSP groups and 24 private seed buyers/traders.

Rice is prime crop that contributes to food security and provides employment to a large number of populations in Nepal. More than 51% of the area of rice land in Nepal is rain-fed. Over the last few years, however, the country has been experiencing erratic rainfall, with less water available for rice cultivation, as well as temperature rise. There are both submergence (flooding) problems and drought in the main rice growing areas. Hence, there is a need to generate suitable rice technologies under such adverse conditions.The International Rice Research Institute (IRRI) has initiated research in collaboration with the Nepal Agricultural Research Council (NARC) and the Institute of Agriculture and Animal Sciences (IAAS) to develop suitable rice technologies for submergence and drought prone areas of Nepal. Various rice germplasm was brought from IRRI, Philippines, and research was conducted at NARC and IAAS as well as in farmers’ fields following a program of Participatory Varietal Selection (PVS). Water-saving rice technologies as well as other technologies, including indigenous practices, were identified for utilizing less water for rice cultivation. Several varieties of rice under drought prone and under submergence conditions were identified, and have been recommended for cultivation by Nepalese farmers.DOI: http://dx.doi.org/10.3126/hn.v11i1.7209 Hydro Nepal Special Issue: Conference Proceedings 2012 pp.69-72

Hybrid Maize

Need  for corn is increasing, both for food, animal feed, and industrial raw materials. This is an opportunity as well as a challenge for the government in increasing corn production towards sustainable self-sufficiency. Superior varieties are one of the components that can significantly increase yield. Hybrid varieties have a higher yield potential than composites so that the use of hybrid corn seeds can increase the yield of corn per crop area. The Agricultural Research and Development Agency (Balitbangtan) has produced hybrid maize varieties with high yield potential, which are no less competitive with other private hybrid maize, but they are not well disseminated. In order to obtain added value for farmers and the development of Balitbangtan corn seeds, NASA 29's hybrid corn seed propagation was carried out at the farmer level. The study was carried out in Salukayu Village, Papalang District, Mamuju Regency in 2018 covering an area of ​​1 ha. The results showed that corn seeds were 1.5 tons / ha. The Nasa 29 hybrid maize seed propagation farm is economically feasible and profitable, as indicated by the R / C value of 2.35, TIP 637 kg / ha, TIH Rp. 10,623, - / kg and IK Rp. 88,985, / day. The study of the propagation of the NASA 29 hybrid maize seed was financially feasible and the economic benefits were high and efficient.

Around 25% of total wheat area in Terai of Nepal falls under rain-fed and partially irrigated condition. A Coordinated varietal trial (CVT) was conducted during two consecutive crop cycles (2011-12 and 2012-13) under timely sown rain-fed conditions of Terai. The trial was conducted in Alpha Lattice design with two replications at Nepal Agricultural Research Council, National Wheat Research Program, Bhairahawa and Nepal Agricultural Research Council, Regional Agriculture Research Station, Nepalgunj. Observations were recorded for yield and yield traits and analyzed using statistical software Cropstat 7.2.The combined analysis of coordinated varietal trial showed that BL 3978 possessed the highest yield (2469.2 Kg ha-1) followed by NL 1097 (2373.2 Kg ha-1) and NL 1094 (2334.06 Kg ha-1). Genotype x Environment interaction for grain yield was significant (p<0.05) over locations and years. BL 3978 with early maturity (111 days) escaped the heat stress environment. Among the top three genotypes, BL 3978 was consistently higher in both favorable and unfavorable conditions. Earliness was one of the major traits for heat tolerant genotypes. The three identified genotypes will be further evaluated in participatory varietal selection or coordinated farmers field trial followed by small plot seed multiplication (seed increase) and release in the future for timely sown rain-fed conditions. These lines also appear suitable for inclusion in crossing program targeted for water stress tolerance variety development.

Quality Control Mechanism

A review on the community based seed production through IRRI/IAAS projects was made to know the seed production situation in western mid hills of Nepal. In Nepal, around 90% of seeds are supplied through informal sector where seed replacement rate (SRR) of major staple food crops is around 10%. The formal seed supply systems are characterized by a vertically organized production and distribution of released or registered varieties by public and private organizations using agreed quality control mechanism. Community Based Seed Production (CBSP) is one of the most important community resources from which, small holder farmers can improve their livelihoods which serves as a means to attain food and nutrition security and income generation to the farmers. IRRI/IAAS collaborative projects (IFAD TAG 706, STRASA and CURE) have establish 15 CBSP organizations in Lamjung, Tanahun, Gorkha and Bajhang district since 2006 to 2014 and producing quality seed annually. Project team has developed a unique type of working modality to get success in research, development and technology dissemination. Conduction of PVS trial annually in key sites, regular training to farmers, exposure visit of farmers, monthly meeting with farmers, regular minikit distribution in new sites, award to best seed producers, collaborative work with respective DADOs are some examples. Though CBSPs have faced major challenges like limitation of fund for seed buying, availability of quality source seed in time and place, availability of machines like moisture meter, grading machines, weighing machines, seed storage problems, marketing problems, natural disasters etc. the projects have contributed in release of rice varieties like Ghaiya-2, Sukhadhan series from 1 to 6, Bahuguni, Hardinath-2 and Chiyarang sub-1 as drought tolerant, and Ramdhan, Sunaulo sugandha, Mithila, Swarna sub 1 and Barkhe 1022 as irrigated varieties during project period.

SummaryMaize production is central to rural livelihoods in the hills of Nepal. Access to affordable improved maize seed has long been a barrier to productivity gains and livelihood improvement. This study evaluates the direct and indirect (spillover) impacts of a community-based seed production program in Nepal using a quasi-experimental method for selected outcome indicators. Our results show that community-based seed production provides a significant positive direct impact on maize income and female leadership opportunities. The impacts were particularly favorable for disadvantaged households (HHs) from lower castes and HHs that owned less land. There is also strong evidence of spillover impacts on improved seed adoption, yield, and household maize self-sufficiency. Community-based seed production thereby could help Nepal attain cereal self-sufficiency and nutritional security as envisioned in the national agricultural development strategy and seed vision.

AbstractSoil microbe is crucial to a healthy soil, therefore its diversities and abundances under different conditions are still need fully understand.The aims of the study were to characterize the community structure and diversity of microbe in the rhizosphere soil after continuous maize seed production, and the relationship between the disease incidence of four diseases and the variation of the rhizosphere microbe. The results showed that different fungal and bacterial species were predominant in different cropping year, and long-term maize seed production had a huge impact on structure and diversity of soil microbial. Ascomycota and Mortierellomycota were the dominant fungal phyla and Mortierella and Ascomycetes represented for a large proportion of genus. A relative increase of Fusarium and Gibberella and a relative decrease of Mortierella, Chrysosporium, Podospora, and Chaetomium were observed with the increase of cropping year. Pathogenic Fusarium, Curvularia, Curvularia-lunata, Cladosporium, Gibberella-baccata, and Plectosphaerellaceae were over-presented and varied at different continuous cropping year, led to different maize disease incidence. Proteobacteria and Actinobacteria ranked in the top two of all bacterial phyla, and genus Pseudarthrobacter, Roseiflexus and RB41 dominated top 3. Haliangium and Streptomyces decreased with the continuous cropping year and mono-cropping of maize seed production increased disease incidence with the increase of cropping year, while the major disease was different. Continuous cropping of maize seed production induced the decrease of protective microbe and biocontrol genera, while pathogenic pathogen increased, and maize are in danger of pathogen invasion. Field management show great effects on soil microbial community.
