Abstract True seed shallot (TSS) has become an alternative material for shallot seeds to fulfil the lack of good-quality seed bulbs. Transplanting was the most popular TSS planting method for farmers. This technic uses seedlings as planting material. The seedling production was the most crucial stage in transferring technology from vegetative propagation (seed bulb) to generative propagation (TSS). This paper reviews the advantages and disadvantages of several seedling techniques and the strategy for selecting techniques and maintaining seedlings that are suitable to the specific conditions at

Abstract:
Lilac (Syringa vulgaris L) seedlings are commonly grown in many seedling nurseries in Michigan. Typically seedlings are lifted in the fall and stored prior to shipment or stored by the customer. A major problem in field production of lilacs is that seedlings often retain their leaves late in the fall. If the leaves are not removed prior to storage or shipment, the seedlings will mold and deteriorate. Therefore, growers must spend additional labor to remove the leaves, often by hand. The goal of this research was to evaluate chemical alternatives to defoliate lilac seedlings in field nurseries.

Abstract:South-East Asian tropical rain forests experience sporadic, but profuse, seed production after general flowering, leading to the synchronous emergence of various seedlings and subsequent seedling dynamics, which play a crucial role in determining species distribution and coexistence. We examined the relative importance of both biotic (initial height, conspecific seedling density) and abiotic (canopy openness, per cent sand, soil water content) drivers using survival data for 1842 seedlings of 12 dipterocarp species for 1.5 y following mast fruiting in an old-growth Bornean tropical ra

Abstract:
Recently, sweet pepper (Capsicum spp.) has been a commercially important crop in Bangladesh. The cultivation procedure is highly sensitive to different environments. In the case of quality production, appropriate seedling age is a prerequisite for higher yield. The experiment was carried out at the Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Shibpur, Narsingdi, Bangladesh during the Rabi season of 2017-2018. Six treatments were used i.e.,. 14 days, 21 days, 28 days, 35 days, 42 days and 48 days at the age of transplanting seedlings. The experiment was co

Abstract:
Ornamental bedding plant operations transitioning to leafy greens and herb production must decide whether to invest in new hydroponic equipment or modify existing culture systems for edible crops. In addition, common practices used to increase space-use and production efficiencies during bedding plant production may be modified for hydroponic leafy greens and herbs, such as purchasing large seedlings for transplant. The objective of the first experiment was to evaluate plant growth in a modified and novel shallow aggregate ebb-and-flood (SAEF) system intended for bedding plant growers with an

The vegetable plug seedling plays an important role in improving vegetable production. The process of plug seedling contributes to high-quality vegetable seedlings. The substrate composition and chemical fertilizer are widely studied to promote seedling growth.

The use of beneficial microbes to promote vegetable seedling growth is of great potential. In this study, we showed that the Serratia marcescens strain LYGN1 enhanced the growth of cucumber

The number of lateral roots ranged from 1 to 34 per seedling with a mean of 12.7 for the total population (600 seedlings). The seedlings were separated into three groups based on the number of lateral roots: A, 20–34; B, 10–19; and C, 1–9. Seedlings of each root group were transplanted outdoors and gro

Nursery-grown tree seedlings are a vital component of successful restoration and reforestation programs, useful when calls for increased planting for industrial forest management are made, and a tool for climate change mitigation. One of the most extensively planted and studied trees in Western North America is Douglas-fir. Building on that body of work, this review was conducted to identify if the root-to-shoot ratio (root:shoot, R:S), a commonly referred-to metric in reforestation planning, yields meaningful guidance for producing seedlings that are better able to establish across a variety

The optimal N range for maximum survival, growth, and early yield in the field was from 100 to 200 mg-liter'. Strength of the seedling stem increased with N level curvilinearly.

ABSTRACT The use of quality seedlings is important in establishing a productive coffee crop. However, the most widely used method to produce coffee seedlings is time consuming (6-12 months) and lacks new production technologies. This study aimed to assess the use of fertigation and a growth regulator in the production of coffee seedlings, in order to develop a system faster than the conventional method. For that, Topázio coffee cultivar seeds were pre-germinated and planted in tubes filled with substrate (composted pine bark), in a protected nursery. A randomized block design was used, in a 4
