Growth of pawpaw\n(Asimina triloba) seedlings in containers was examined in a factorial greenhouse experiment with four treatment levels of the slow-release fertilizer, Osmocote 14–14–14 (14N–6.1P–11.6K), incorporated in Pro-Mix BX potting substrate at 0, 0.13, 0.26 or 0.81 kg·m[p1.4.1] (0, 0.22, 0.44, or 1.37 lb/yard[p1.4.2]) and three treatment levels of liquid-feed fertilizer of Peters 20–20–20 (20N–8.7P–16.6K) water-soluble fertilizer at 0, 250, or 500 mg·L[p1.4.3] (ppm). When plants were harvested 18 weeks after sowing, seedlings subjected to the highest rate of Osmocote 14–14–14 at 0.81 kg·m[p1.4.4] and liquid-feed at 500 mg·L[p1.4.5] had the greatest total biomass, about 3-fold greater than nonfertilized plants. In a separate greenhouse experiment, growth of seedlings was examined",

Early seedling growth was hastened in the 2.22 kg·m[p1.5.3] treatment rate, but delayed in 17.7 kg·m[p1.5.4] treatment rate, when compared to nonfertilized control plants. When seedlings were harvested 17 weeks after sowing, plants had the greatest shoot, root, and total dry weight with Osmocote 14–14–14 at a rate of 2.22 kg·m[p1.5.5]. Root:shoot ratio decreased from about 1.5 without Osmocote 14–14–14, to about 0.65 at rates of 2.22 kg·m[p1.5.6] or greater. Based on the results of this study, the slow-release fertilizer, Osmocote 14–14–14, can be used effectively as a sole fertilizer source when incorporated into potting substrate at a rate of 2.22 kg·m[p1.5.7] or at a reduced rate of 0.81 kg·m[p1.5.8] when supplemented with weekly applications of liquid-feed fertilizer at a rate of 500 mg·L[p1.5.9] of Peters 20–20–20, to enhance production of container-grown pawpaw seedlings.",

Historically,\npawpaws have been difficult to propa-\ngate. Pawpaws develop a strong tap-\nroot with a fragile root system, which\ncan be easily damaged upon digging;\ntherefore, most commercial nurseries\nin the United States propagate their\nown pawpaw trees in containers (un-\npublished). Although this results in a\nsignificantly greater cost to the pur-\nchaser, trees usually have a strong, healthy\nroot system for field establishment. Un-\nfortunately, high prices for seedling and\ngrafted trees are limiting the develop-\nment of a commercial pawpaw industry.\nRecent studies at Kentucky State Uni-\nversity have developed recommendations\n(e.g., potting substrate type, the\nuse of tall containers to accommodate\nthe seedling’s strong tap root, etc.) to-\nward the successful container produc-\ntion of pawpaw (Finneseth et al., 1998a,\n1998b; Jones et al., 1998; Layne, 1996;\nPomper et al., 2002a, 2002b). How-\never, further improvements in cultural\nmethods for container production of\nrobust pawpaw seedlings for grafting,\ntransplanting to orchards, or home land-\nscapes would be desirable.\nThere is little information available\non the fertilization requirements of paw-",

Osmocote is a popular encapsulated, slow-release fertilizer that provides a relatively constant supply of nutrients for plant absorption over a fixed time frame. Because fertilizers such as Osmocote release nutrients slowly, they eliminate the need for labor-intensive liquid fertilization that may lead to excessive nutrient leaching and contamination of ground water (Nelson, 1998). Osmocote, alone or in combination with water-soluble fertilizer, has been used to successfully produce many tree species in containers. For example, false weymouth pine (Pinus pseudostrobus) and douglas pine (Pinus douglasiana) trees grew well when fertilized using Osmocote 14–14–14 at a rate of 4 kg·m⁻³ (6.74 lb/yard³) (Mexal et al., 1995). River birch (Betula nigra), bald cypress (Taxodium distichum), sycamore (Platanus occidentalis), and weeping willow (Salix babylonica) have been grown successfully outdoors in containers with Osmocote 16–7–12 (16N–3.1P–10K) at a rate of 13 kg·m⁻³ (21.9 lb/yard³) (Ruter, 1994). Green ash (Fraxinus pennsylvanica) and red oak (Quercus rubra) have been grown successfully in containers with Osmocote 18–6–12 (18N–2.6P–10K) at a rate of 3.6 kg·m⁻³ (6 lb/yard³), supplemented with weekly applications of 200 mg·L⁻¹ N from 20–20–20 (20N–8.7P–16.6K) water soluble fertilizer (Arnold and Struve, 1989). Pomper et al. (2002b) found that pawpaw seedlings grew well in Pro-Mix BX potting substrate (Premier Horticulture, Inc., Red Hill, Pa.) with weekly liquid-feed applications of 500 mg·L⁻¹ Peters 20–20–20 water-soluble fertilizer plus soluble trace elements; however, further examination of specific nutritional requirements for container production of pawpaw seedlings could lead to enhanced growth of seedlings.",

Seed was stratified at 5 °C (41 °F) for 3 months and was sown to a 3-cm (1.2-inch) depth in moist Pro-Mix BX potting substrate in 5 × 6.4 × 25.4-cm (2 × 2.5 × 10-inch) Roottrainers (Hummert Intl., Earth City, Mo.) with a volume of 740 cm³ (45 inch³). The initial electrical conductivity (EC) of Pro-Mix BX substrate was determined to be 1.02 dS·m⁻¹ and the nitrate (NO₃)⁻ concentration at 18 mg·L⁻¹ by the University of Kentucky Division of Regulatory Services (Lexington). Seedlings were grown in a white-washed glass greenhouse under a 16-h photoperiod supplemented by high-pressure sodium lights. At noon on a representative sunny day on 27 Apr. 2000, photosynthetic photon flux (PPF) was measured at 1200 μmol·m⁻²·s⁻¹ at canopy level using a LI-185B photometer with a Q7072 quantum sensor (LI-COR, Inc., Lincoln, Nebr.) with the supplemental lights on.",

Each subplot treatment consisted of a Rootrainer (27 cells) that contained Pro-Mix BX to which appropriate amounts of slow-release fertilizer had been incorporated. On 7 Feb. 2000, single seeds were sown into each cell of the Rootrainer so that in each of the three replicate blocks, 27 seeds were sown per treatment combination. A total of 972 seeds were sown (3 blocks × 3 main plot treatments × 4 subplot treatments × 27 seeds = 972 seeds). Seedlings were watered to saturation at least once each week, or as needed during the experiment. Ten weeks after sowing, on 17 Apr. 2000, when plants attained the two- to three-leaf stage, seed germination rate was recorded. At this time 10 uniform seedlings per experimental combination, or Rootrainer, were marked in each block, and leaf number and height were determined. Weekly fertilization treatments were also initiated at this time by manually saturating media with the appropriate liquid fertilizer; water used for preparation of the treatments had a total N content [NO₃ and ammonia (NH₄)] of about 0.7 mg·L⁻¹ (Scott Laboratories, Allentown, Pa.). The number of leaves per plant and seedling height were recorded on 13 June 2000, 18 weeks after sowing, when plants were destructively harvested. Stems, leaves, and roots were oven-dried at 70 °C (158 °F) for 48 h and weighed. The greenhouse air temperature was measured every 30 min during the experiment using TEMP HOBO sensors (Onset Computer Corp., Pocasset, Mass.).

When plants in the slow-release and liquid-feed fertilizer application experiment were fertilized with the high rate of Osmocote [0.81 kg·m⁻³ (1.37 lb/yard³)], and 500 mg·L⁻¹ liquid-feed fertilizer, total plant dry weight [3.53 g (0.12 oz)] was greater than that [2.46 g (0.09 oz)] of plants in sole slow-release fertilizer application experiment receiving treatment B of Osmocote as the sole fertilizer application.

Thus, the greater total plant dry weight of seedlings in Expt. 1, fertilized with the high rate of Osmocote [0.81 kg·m⁻³ and 500 mg·L⁻¹ liquid-feed fertilizer, than in seedlings in Expt. 2, fertilized solely with treatment rate B of Osmocote, was achieved even though the plants in Expt. 1 received only about 50% as much total N as plants in treatment B. The greenhouse environment was warmer during Expt. 1 than during Expt. 2, which may have promoted growth of the seedlings during the former experiment. The warmer greenhouse temperatures may have promoted greater nutrient release rates by the Osmocote; however, since higher nutrient treatment rates in the slow-release fertilizer application only experiment did not enhance growth further, the warmer temperatures in the earlier experiment likely resulted in greater plant biomass accumulation by stimulating plant growth and nutrient uptake. Pomper et al. (2002b) found that bottom heat [32 °C (90 °F)] increased total pawpaw seedling dry weight by 87% compared to plants grown at ambient root-zone conditions [24°C (75 °F)]. Other differences in the cultural conditions during the experiments could also have affected plant growth; spring PPF may have been lower than summer levels. Seedlings grown at either the high rate of Osmocote (0.81 kg·m⁻³), supplemented with 500 mg·L⁻¹ Peters liquid-feed fertilizer, or Osmocote in treatment B had similar root to shoot ratios of about 0.65, indicating that both these fertilizer regimes resulted in excellent seedling shoot production.",

Tall containers are used in the production of pawpaw seedlings in order to accommodate the strong taproot produced (Layne, 1996). Further studies to determine the effect of the placement of slow-release fertilizer application in containers (incorporated uniformly throughout the container versus top-dressing) on nutrient leaching and pawpaw seedling growth would be desirable. More frequent application of smaller quantities of slow-release fertilizer and placement in the container could also be helpful to reduce nutrient leaching; however, this would",
