This study performed tests for helping not only improving seedling raising efficiency but producing high-quality daughter plant with analyzing the effects of seedling quality on growth and yield after field planting by management method at seedling raising stage of strawberry ‘Seolhyang’ 1. Effect of nutrient management for mother plant on daughter plant 1) For the nutrient management of mother plants, SAF>NS+EM>NS was observed depending on types of additional fertilizers. The nutrient was believed to increase as concentration and dilution rate of additional fertilizers are within the optimal range(NS 0.8, SAF 300). It was also learned that increase on dry weight of the mother plant leaves would be increased proportionately to the mineral elements and chlorophyll contents and photosynthetic activity as well as growth of the mother plants. 2) Productivity of daughter plants was found to be higher in order of NS+EM>SAF>NS depending on types of additional fertilizers. The productivity appeared to be increased as the concentration and dilution factor of additional fertilizers was treated beyond(NS 1.6, SAF 200) the optimal range(NS 0.8, SAF 300). It was also learned that increase on dry weight of the daughter plant leaves would be increased proportionately to the growth and mineral elements of the daughter plants. 2. Effect of light condition on seedling quality 1) For cutting experiments, the growth increased in order of Enclosed type>Open type>Open type(Conventional cultivation) shielding conditions for the daughter plants, the greater in order of 2>3>1>4 daughter plant order and 3>2 number of leaves. After the light treatment, the crown got diameter and along with that, the plant height, fresh weight, root length and root weight were also increased. 2) For experiments using artificial lights, the content of chlorophyll was observed higher as the light quality is close to red(R) and photosynthetic activity was getting higher proportionally to photosynthetic photon flux density(PPFD). In short, aerial part was to increased the plant height, leaf length, petiole length at red light(R) and turned out to cause the greatest increase in crown diameter, leaf width, number of leaves at available light(AL) having the highest values for PPFD. 3. Effect of seedling quality and seedling raising method on yield 1) After planting depending on the crown diameter, plant height appeared to improve more as the crown got diameter. The yield was observed to be greater in order of 10>8>6>4mm of the crown diameter. 2) The daughter plant order would not been found difference the growth of plant height after planting. Also for the yield, there had not been found difference from the first daughter plant to the fourth daughter plant which was only 1,063～1,105kg/10a. 3) Seedling raising type would not been found difference the growth of plant height after planting. However, for the yield was roots restricted seedling raising(Soils)>port seedling raising(Conventional cultivation)>seedling collection all at once>seedling collection all at once of harvest mother plants>roots restricted seedling raising of harvest mother plants(Chaff). 4) Rootage time would not been found difference the growth of plant height after planting. However, for the yield was determined to be greater in order of Jul. 1st(Conventional cultivation)>Jul. 15th>Jul. 20th>Jul. 25th>Jul. 30th.
