Cost Analysis of Seedling Production at Northern Forest Seed Centre

Abstract

The cost analysis of seedling production in the Northern Forest Seed Centre. The objective is to assess the cost of economic seedling production and guideline for tree management to reduce costs and increase the efficiency of seedling production by selecting the seeds of 10 types of economic forest trees, 4 families. From the survey of people's needs for seedlings, from the tree planting station, Lampang Province. From a good quality seed source by using different methods of germination of each type of seed. It was found that the production cost of Fabaceae family seedlings consisted of 5 types including Dalbergia cochinchinensis Pierre, Pterocarpus macrocarpus Kurz., Dalbergia oliveri Gamble ex Prain., Afzelia xylocarpa (Kurz) Craib., and Xylia xylocarpa (Roxb.) Taub. The seedlings of the Dipterocarpaceae family have 2 types consists of Dipterocarpus obtusifolius Teijsm. ex. Miq.and Dipterocarpus alatus Roxb. ex G.Don. There are 2 types of saplings of the Poaceae family were  Dendrocalamus strictus (Roxb.) Nees and Thyrsostachys siamensis Gamble. And the Lamiaceae family seedlings were Teak (Tectona grandis Linn.f.). Total cost of producing seedlings of 10 types of economy, 4 families found that cost expense including seed cost, cost of planting material, labor wages, cost of materials for nursery equipment, equipment repair costs, prevent disease and insect disease care and other expenses. According to research studies, the cost is higher than the economic seedling production at the plant nursery station in Lampang Province. Because the source of the seed is perfect, free from disease and insects, use suitable planting materials for planting seedlings. The main consideration is sand mixed to make the drainage and air better. Burnt rice husk mixed to make good drainage and air, light weight, increase alkalinity. Manure, compost mixed to increase nutrients, make the soil cohesion, and absorb water better. Coconut coir, sawdust, mix to absorb water and add organic matter, maintenance of seedlings, fertilizing, weeding, root drop and root cutting prevent roots from growing outside the bag, Seedling and height sorting so that the seedlings receive light and water thoroughly, making seedlings tough for drought tolerance and sunlight, transport and other adverse conditions for at least 3 months before planting.
