Because of high nutrient contents and ununiform physical properties of root media, many problems have been took place in production of grafted plug seedling of vegetable crops. This research was conducted to assess the soil physico ․ chemical properties of root media in raising of rootstock and scion for grafting, success of grafted union, and acclimation.
1. Effect of pre-planting fertilizer levels on growth of rootstock and scion plants and changes in soil nutrient concentrations
Plant growth of tomato rootstock 'J3B' showed good plant growth in 1.0X treatment of pre-planting fertilizer level. But the growth of tomato scion 'Sunmyung' increased until pre-planting fertilizer level (PPFL) elevated up to 2.0X. In considering of the results of soil chemical properties, the fertilization should be adjusted to maintain soluble salt level of root media less than 1.30dS․m-1 in production of tomato rootstock and scion. The fresh and dry weight of hot pepper rootstock 'Conesian hot' increased until the PPFL reached 4.0X in P+P, P+V, C+V root media. But those in hot pepper scion 'Knockgwang' showed the highest in 2.0X treatment. The fresh and dry weight of cucumber rootstock 'Heuckjong hoback' showed big differences among root media when PPFL were lower, but the differences were not significant when PPFL were high. Cucumber scion 'Joeun backdadagi' growed well in the treatments of low PPFL indicating that salt tolerance of 'Joeun backdadagi' is weak. The fresh and dry weight of watermelon rootstock 'Chambak' increased when the PPFL reached up to 4.0X indicating that the rootstock has very high salt tolerance. But the watermelon scion 'Taeyang Ggul' growed well in treatment of 0.5and 1.0X PPFL.
2. Effect of leaching fraction in fertigation and irrigation on growth of rootstock and scion plants and changes in soil nutrient concentrations
Tomato rootstock showed higher fresh and dry weight in peatmoss containing root media than those in coir containing root media when leaching fraction (LF) of root media was low. The elevated LF did not increased the fresh and dry weight of tomato scion 'Sunmyung'. The fresh and dry weight of hot pepper rootstock were heavier in peatmoss containing root media than those in coir containing root media when LF was higher than 1.0X. The hot pepper scion 'Knockgwang' had heavier fresh and dry weight in root media containing vermiculite than those in root media containing perlite. The LF 0 in P+P and P+V media performed well for growth of cucumber rootstock and scion compared to LF 0.5 and 1.0. The elevated LF in raising of watermelon rootstock resulted in increase of fresh and dry weight. But the root medium with the highest freash and dry weight in each LF were different and trends were not observed in raining of watermelon scion.
3. Effect of medium compaction during tray filling on growth of rootstock and scion plants and changes in soil nutrient concentrations The elevated medium packing density (MPC) during container filling of root media increased plant growth of tomato rootstock. Tomato scion 'Sunmyung' showed good growth in MPC 1.5X. Hot pepper rootstock 'Conesian hot' and scion 'Knockgwang' had the highest fresh and dry weight among treatments of MPC. The treatment of MPC 1.5X had the highest fresh and dry weight in raising of cucumber rootstock among treatments of MPC. The elevated MPC of root media increased plant growth of 'Joeun backdadagi' in peatmoss containing media, but those decreased plant growth in coir containing root
media. The root media containing vermiculite such as P+V and C+V performed better than those containing perlite such as P+P and C+P for growth of watermelon rootstock 'Chambak'. The MPC 2.0 in root media containing perlite showed higher fresh and dry weight compared to MPC 1.0 and 1.5. The differences in fresh and dry weight were higher among root media of MPC 1.0, but the differences were not significant as MPC were elevated up to 2.0X.
4. Effect of pre-planting fertilizer levels on growth of grafted plug seedlings and changes in soil nutrient concentrations during success of grafted union and acclimation
The elevated pre-planting fertilizer level (PPFL) increased fresh weight of grafted seedling of tomato (rootstock 'J3B'/scion 'Sunmyung') when the seedlings were grown in root media containing peatmoss, but the growth was the highest in 1.0X treatment of coir containing root media such as C+P and C+V. The root media containing vermiculite such as P+V and C+V performed better for growth of grafted plug seedling of hot pepper than those of perlite containing root media such as P+P and C+P. The electrical conductivity of coir containing root media such as C+P and C+V was higher than peatmoss containing root media such as P+P and P+V. The elevation of PPFL from 0 to 2.0X increased plant growth of grafted plug seedlings of cucumber, but the growth was decreased when PPFL was set to 4.0X.
5. Effect of leaching fraction in fertigation and irrigation on growth of grafted plug seedlings and changes in soil nutrient concentrations during success of grafted union and acclimation
The elevation of LF in root media containing peatmoss increased plant growth of grafted plug seedling of tomatoes. The elevation of LF from 0 to 1.0 in root media containing coir increased plant growth, but those over 1.0 decreased plant growth. The electrical conductivity of P+P, P+V, C+P and C+V media at LF 2.0 were 0.833, 1.860, 2.923, and 0.310 dS․.m^-1, respectively. The elevated LF in P+P and P+V media increased plant growth, but those in coir containing root media such as C+P and C+V did not increased fresh and dry weight of grafted hot pepper plug seedlings. The fresh weight of grafted seedlings of cucumber were heavier in root media containing perlite than root media containing vermiculite when LF was set to 0.5 and 1.0. However, those were heavier in vermiculite containing root media than in perlite containing root media when LF was higher than 1.0X.
6. Effect of medium compaction during tray filling on growth of grafted plug seedlings and changes in soil nutrient concentrations during success of grafted union and acclimation
The elevated medium packing density (MPC) in peatmoss containing root media increased fresh and dry weight of grafted plug seedlings of tomatoes.
The fresh weight did not show significant differences among root media when MPS was set to 1.5X. The treatment of 2.0X had heavier fresh weight than 1.5X in P+V and C+V root media, but those of 2.0X decreased compared to 1.5X in P+P and C+P media. The dry weight of grafted hot pepper seedlings were heavier in peatmoss containing media than in coir containing media when MPC was set to 1.0X. The P+P medium produced the highest fresh weight followed by P+V, C+P and C+V when MPC was set to 1.5X.
The growth of grafted plug seedlings of cucumber did not significantly affected by root media as well as MPC.
7. Effect of various post-planting fertilizer concentrations with fixed pre-planting fertilizer level on growth of grafted plug seedlings and changes in soil nutrient concentrations during acclimation
The elevated post-planting fertilizer concentration (PPFC) from 0 to 100 mg･L^-1 during acclimation increased plant growth of grafted plug seedling of tomatoes. The highest PPFC such as 200 mg･L^-1 decreased plant growth compared to 100 mg･L^-1. The C+P medium produced less fresh and dry weight than other root media in all fertilizer concentration. The fresh and dry weight of grafted plug seedlings of hot pepper were heavier in P+P medium followed by P+V, C+V and C+P media in all fertilizer concentrations. The fresh and dry weight of grafted plug seedlings of cucumber did not show significant differences among root media in PPFC 0, but differences were significant among root media when PPFC were set to 50 and 100 mg･L^-1.
The treatment of 50 mg･L^-1 produced the higher fresh weight in watermelon than other PPFC in all root media. The higher or lower than 50 mg･L^-1 decreased the growth of grafted plug seedlings of watermelon. The root media of P+P and C+P produced the higher fresh and dry weight than those of P+V and C+V. The elevated PPFC resukted in increased soil N, P₂O₅, and K₂O concentrations and decreased Ca, Mg and Na concentrations.
8. Effect of various post-planting fertilizer concentrations with fixed leaching fraction during success of grafted union on growth of grafted plug seedlings and changes in soil nutrient concentrations during acclimation
The elevated PPFC from 0 to 100 mg·L^-1 resulted in big differences of fresh and dry weight of tomatoes among root media. The P+P and P+V media produced higher fresh and dry weight than C+P and C+V media when PPFC were set to 0 or 50 mg･L^-1. The C+P and C+V media produced higher fresh and dry weight than P+P and P+V media when PPFC were set to over 100 mg･L^-1. The elevation of PPFC decreased electrical conductivity of root media in P+P, C+P and C+V media and increased that in P+V medium. The P+P medium performed worse than other three root media for growth of grafted plug seedlings of hot pepper. The 100 mg･L^-1 of PPFC produced the highest fresh and dry weight among all PPFC in root media except P+P. The P+P medium produced the highest dry weight of grafted cucumber among root media when PPFC was set to 0.0, but C+V medium produced the highest dry weight among root media when PPFC was set to 200mg･L^-1. The elevated PPFC in all root media increased electrical conductivity of all root media. When consider the growth of grafted cucumber seedlings, the EC should be adjusted to less than 2.0 dS․.m^-1. The growth of grafted watermelon seedlings decreased when PPFC were elevated over 100 mg･L^-1 and the EC shoud be adjusted less than 2.0 dS․.m^-1 to produce good quality grafted plug seedlings of watermelon.
9. Effect of various post-planting fertilizer concentrations with fixed packing density during tray filling on growth of grafted plug seedlings and changes in soil nutrient concentrations during acclimation
The treatment of PPFC 0 showed best growth of grafted tomato seedlings.
To produced good quality grafted tomato seedlings, the electrical conductivity should be adjusted to less than 1.0 dS･m^-1 in peatmoss containing media and 1.5 dS․.m^-1 in coir containing media. The P+P and P+V performed better than C+P and C+V in all fertilizer concentration for growth of grafted hot pepper seedlings. The fresh and dry weight of hot pepper seedlings were the highest in P+P followed by P+V, C+V and C+P. The differences in fresh and dry weight of grafted plug seedlings of cucumber were not significant among root media, but those were significant when PPFE were elevated upto 100 mg･L^-1. The recommended electrical conductivity of root media were less than 2.0 dS․.m^-1 in peatmoss containing media and 3.5 dS․.m^-1 in coir containing media in production of good quality of grafted cucumber plug seedlings. The P+P and P+V media performed better than C+P and C+V media in production of grafted plug seedlings of watermelon. 10. Practical application of research results and economic analysis The P+P, P+V, C+P and C+V produced the highest fresh weight of grafted hot pepper plug seedlings when PPFC were set to 50, 0, 50 and 200 mg･L^-1, respectively, among PPFC in each root media. The P+P, P+V, C+P and C+V produced the highest fresh weight of grafted cucumber plug seedlings when PPFC were set to 100, 200, 50 and 200 mg･L^-1, respectively, among PPFC in each root media. The P+P and P+V media performed better than C+P and C+V media in production of grafted tomato plug seedlings. The 50 mg･L^-1 in PPFC produced the highest fresh weight among PPFC in all root media.
When LF was fixed to 0.5X in experiment 3 and PPFC were varied, P+P medium performed better than other media in growth of grafted hot pepper seedlings. The P+P, P+V, C+P and C+V produced the highest fresh weight of grafted cucumber plug seedlings when PPFC were set to 100, 100, 50 and 50 mg･L^-1, respectively, among PPFC in each root media when LF was fixed to 0.5X in experiment 3 and PPFC were varied. When pre-planting packing density of root media was set to 1.5X and post-planting fertilizer concentrations were varied, the treatment of 50 mg･L^-1 PPFC produced the highest fresh weight of grafted hot pepper seedlings in P+P and P+V media.
The 50 mg･L^-1 in PPFC produced the highest fresh weight of grafted seedlings of cucumber among PPFC in all root media. The root media containing peatmoss performed better in production of fresh weight than those containing coir. The amount of income elevated by production of high quality of grafted seedlings of watermelon, hot pepper, tomato, and cucumber were 52,000, 21,000, 39,000 and 14,600 thousand won when a grower produce grafted plug seedlings in 1,000 pyung of protected house.
