Raising seedlings in Nurseries

Posted by Sanjeeva Reddy on

                                Saplings of vegetables

Sowing healthy seeds or seedlings leads to the healthy and better harvests. Present agriculture technologies enforces to produce sturdy and healthy seedlings

Some of the seeds of vegetable crops like tomato, brinjal, capsicum and cucurbits are first raised in nursery under protected conditions to achieve maximum germination count and healthy plant establishment and then transplanted to main field.

                        Tomato, Brinjal and Capsicum seedlings

Farmers and nursery managers are raising seedlings in plug trays or portrays to produce the healthy seedlings. Soil less media with coco-peat, vermiculite and microbial consortium is usually used to sow the seeds and the rooting media. Sowing is done manually and also with seed sowing machine.

                        Saplings raised in portrays

Importance of vegetable seedlings production in protected nursery

  • Less loss of expensive seeds
  • Proper seed germination, uniform growth, least seedling mortality
  • Least pest and disease incidence

                         Sowing seeds

Components and process involved in modern nursery raising system

Seeds, Seedling tray, media, mechanization, irrigation, nutrients, protected structure, light and seed pelleting and priming, biological enhancement and hardening.

Seedling tray:

          Seedlings trays

Different sized trays with varied numbers of cells are used to grow the seedlings in vegetable nurseries. The number of cells in portray varies from 72 to 800 cells per standard tray (53.7 X 27.5 cm). Size of the cell is important as it controls the amount of media used as well as water holding capacity. Seedlings produced in larger cells are taller and have greater dry weight than those grown in small cells

Growth Media

The chemical and physical properties of the growing media is a key factor for successful nursery production.Optimum root growth  is largely dependent on physical characteristics of media like water, aeration and nutrient holding capacity of the media.

                                    Seedling growth media

Sterile growing media must be used and may or may not be inert, but it should have proper cation exchange capacity (CEC) which is associated with pH and nutrient absorbing capacity. Coco peat which is a byproduct of extraction of fiber from coconut husk a 100 % natural, biodegradable, fibrous and spongiest material is normally used as main ingredient of nursery growing media. It has high C: N ratio, high water holding capacity about seven to nine times of its own weight.

                                    Cocopeat for nursery media

Coco peat has antifungal and antibacterial properties. For additional benefits to growing seedlings biological agents like biofertilisers and Trichoderma viride and Pseudomonas fluorescens  are usually mixed to media. Normally approximate 1.2 kg of cocopeat is required for filling one portray.

                                     Trichoderma for cocopeat Pseudomonas flourescence for nursery media


                                      Germinating seeds

Better germination   of seeds depend upon the temperature and usually should be warm with uniform moisture in the media. Customized germination chambers are designed to use in nurseries for better germination. Black polyethylene sheet is used to cover the portrays after sowing to facilitate warmer temperature to initiate germination.

                                              Incubation chamber for seed germination  

Ideal temperature in root zone required for some of the vegetable seeds to germinate

Tomato and Brinjal 210 C – 240 C ; Chilli and capsicum 28 0 C to 320 C

The ideal root zone temperature is 26 0C to 290 C during the first four weeks of growth of seedlings and 20 0C to 26 0C during the fifth and sixth weeks.

                                   Incubation release of seedling trays


                                  Irrigating the seedlings

Seedlings should be irrigated regularly for better growth and development of the seedlings. Nursery growers use rose can or flush boom to irrigate the seedlings. Over watering also is dangerous for the growing seedlings as there might be chances of developing foliar diseases, collar and root diseases.

                                  Watering the young plants


Nutrition for growing young seedlings is very much necessary apart from the nutrients present in the cocopeat or growing media. The nutrition is supplied through foliar application for the growing seedlings.

                                 Nutrients for nursery seedlings

For better root growth phosphorous is required with little nitrogen sso 12:61:00 root drenching may be applied once at 12th day after germination. Once micronutrient mixture may be sprayed 15 days before transplanting. Deficiency of any nutrients may lead to poor and stunted growth of plants and resulting in poor performance.

Protected structure

                   Protected structure for seedlings raising

Young growing seedlings requires extra protection at the younger stage as they are soft and tender so that the sucking pests are very much attractive to suck the juice and at the same time they act as vectors to spread many contagious and deadly diseases those may occur later in plant development stages.

  Sucking pests in nursery

These kind of chances are more when the seedlings are raised outside the protected structure or open field.Protective structure also protect the young seedlings from adverse climatic conditions like rain, wind, heat and many diseases.

Poly house

In protected structures, poly house kind of structures are constructed with transparent UV stabilized polyethylene film 200 micron thickness as covering the poly house roof. A retractable or movable shade nets, at about 11 feet height are provided for regulating heat and light in the ploy house.

                         Poly house structure for nursery

The sides of the poly house structure is usually covered with 200 micron thick polyethylene film to a height of 3 feet from the ground level, to have better protection from rain splash. From 3 feet height the side wall is covered with 40 micron white colored insect proof net from all the four sides.

Shade net nurseries

A shade net nursery is usually erected using GI pipes or stone slabs as a support. HDPE green or black colour UV stabilized shade net of 50 to 75% shade intensity is used to cover the nursery area at a height of 6.5 feet. Strong stainless wire grid is provided at the top of the structure as support for shade net.

                    Shade net structures for nursery 

UV stabilized 40 % nylon insect proof net mesh is fitted on all the four sides of the nursery to prevent insect entry. Polythene sheet is to be provided to pull over the pro-trays in the event of rainfall by way of making low tunnel structure.

The structures should be provided with an ante chamber with two doors constructed at opposite directions where entry or exit to the poly house is made through the first door and then after closing the first door, the second door is opened to make an entry into the poly house.

                         Potassium Parmanganate sloution for hand wash

Both the doors are not opened at single time or simultaneously so that pest entry into the protected structures is not given a chance to enter and attack the young seedlings. A small concrete trough of 2 meter length, 1 meter breadth and 2 inch depth should be prepared between the two doors of antechamber for facilitating washing legs in the disinfectant solution (Potassium permanganate) to prevent any contamination inside the nursery structure.


                                  Light for the polyhouse

Light requirements for seedling growth and development is very important and very crucial. Structure need to be constructed in such a ways that sufficient light is ensured for seedling production.


Hardening is the process of gradually exposing grown up seedlings to the normal climatic condition from protected condition to reduce stress and reduce transplanting shock when seedlings are transplanted to the main field.

                                   Hardening of the seedlings

Hardening may be done by increasing light intensity slowly or exposing transplants under full sunlight, reducing irrigation or watering and fertilizer application.

Pest and disease management.

                                 Diseases in Nursery

  • Cleanliness and hygiene in the nursery, among the crate or portrays is most important role in the control of pests and diseases.
  • Regular sterilization of the growing media, structures, tools and trays must be done with use of steam or chemical.
  • Disease prevention may be effective with proper and effective ventilation and air movement within the nursery area.                                     
  •                             Spraying for nursery plants  
  • Pests and diseases that could affect the growth of healthy seedlings to be understood and effective measures need to be planned well in advance.
  • Pesticides application should be carried out with extra care and be aware that greenhouse/ Nursery raised plants may be more sensitive to chemicals than in the open field.

  • Матча, alias маття, — это порошок из молодых чайных листьев. В отличие от листового чая матча не заливают кипятком и процеживают, а растворяют в воде.

    Напиток яркого зелёного цвета появился в Японии в конце XII века, когда буддийские монахи завезли в страну из Китая семена чая и изобрели принадлежащий метод выращивания растения.

    Тень для равнина позволяет чаю матча уберегать ясный цвет
    Молодые чайные кусты для матча весной накрывают специальными конструкциями из тростника и соломы. Малость позволяет чаю охранять ясный краска и накапливать больше аминокислот и хлорофилла. Чтобы предотвратить распад полезных веществ, листья обрабатывают паром и вялят в ход нескольких недель, потом чего размалывают в дробный порошок.

    Традиционно матча заваривали особым способом и пили без добавок, но в наши жизнь на основе этого продукта стали готовить не исключительно различные напитки, но и десерты. Кто?то даже добавляет его в основные блюда.

    Чем полезен чай матча
    После пределами Японии пойло стал популярным прежде только из?за своих полезных свойств. Учёные выяснили, что матча положительно влияет на здоровье.

    Защищает клетки от повреждений [url=]Маття[/url]
    В матча, вроде и в любом чае, тьма катехинов — природных антиоксидантов. Эти вещества защищают устройство от свободных радикалов, разрушающих клетки, вызывающих старение и сердечно?сосудистые заболевания.

    Около заваривании обычного чая богатые катехинами листья выбрасывают. А лекарство матча весь растворяют в воде, следовательно антиоксидантов в таком напитке больше в 137 раз.

    Помогает защитить печень
    В 2016 году учёные отобрали 80 людей с неалкогольной жировой болезнью печени. Им предложили ежедневно лакать извлечение матча. И посредством 90 дней сословие испытуемых улучшилось.

    Другое исследование показало, что этот думать помогает уменьшить капитуляция печени и почек у крыс с диабетом второго типа.

    Испытание, проведённый китайскими врачами, помог сделать заключение о часть, сколько человек, пьющие напитки из листьев зелёного чая, реже страдают болезнями печени. Всетаки сами учёные не спешат звать матча панацеей. Дабы оценить его эффективность в профилактике гепатита тож цирроза, нужны длительные клинические исследования.
