                      HIGH TECH NURSERIES 

          Article by : Spandana  jakkula

  • High Tech Nursery is a combination of poly green house and agrinet House. Vegetative reproduction is used in such Nurseries to ensure genetic similarities with the source. 


  • High Tech Nurseries over come the limitations like poor control over Climatic Factors, low germination percentage, longer duration, and high cost involved in conventional methods of Plant raising.      

  • Poly Green House is erected in direction parallel to East- West over angle irons, pipes, or wooden post. 

  •  It is erected by fixing mild steel pipe at an Interval of 4.0 Mtr.Distance having Height of 2.50 Mtr.with an area of 32.0 x 8.0 Mtr.as per National Botanical Research Institute Lucknow.

  • .The structure should be covered by Ultra Violet radiation proof polythene sheet made by I.P.C.L. The structure should have a cemented Floor and cemented working table.


  • Inside Poly Green House mist formation Device and Humidity Control System are installed. Tempreature  is controlled by installing two exhaust Fans in front portion and a cooling pad at its back portion.

  • Inert medium like vermiculite is used in root trainer.

  • Cuttings are disinfected by placing in KmnO4 (Potassium permagnet) solution. 

  • Temperature and humidity are generally maintained between 25-300c and 70 - 80% respectively in poly green house. 

  • It takes about 3 to 4 weeks to develop roots.


What is hi tech protected cultivation technology?

   Protected Cultivation is a modern technique in which cultivation of plants under partially controlled conditions which promotes the off-season cultivation of plants. Various techniques are involved like polyhouses, low tunnel plastics, Green house etc.


 AGRINET HOUSE :-


  • Agrinet House is a Structure Fabricated by angle Iron post or Iron pipe with Dimensions 32 M. x 8 M. x 2.5 M. and covered by green agrinet. 

  • Tender seedling in poly green house are shifted to agrinet house for further growth in an Ideal nutrient soil mixture in root trainer for 30 to 45 days.

  • Irrigation is done by micro sprinkler Fitted 3 M. Apart with 0.75 M. height.

  • Tender seedling are kept 1 to 1.5 months in agrinet House for growth. 

  • The agrinet plants are hardened for field conditions by keeping in open Atmosphere for about 20 days with restricted watering .

ROOT TRAINER : -


  • Root Trainers are conical cells having 5 to 6 ridges inside and with a small Drainage Hole on the bottom. 

  • These cones in fact train the root naturally in a way that roots develop parallel to ridges inside the cone and are self pruned without coiling when come out of drainage hole on contact of air and sun light and for this reason the blocks of root trainer are kept on stands which are about 15 cm. above the ground level. 

  • Root trainers blocks can be transported easily, long lasting, require less growth medium and water. 

  • The application of fertilizer and insecticide is also easy in root trainer. 

  • Pest control management is also easy in root trainer method.

POTTING MIXTURE :- 

                                    Generally two type of potting mixtures are used in High Tech Nursery. 

1.VERMICULITE (INERT MEDIUM) :- 



                                                        Root formations in juvenile Branch cuttings do not require any supplementation of nutrient as it happens with the help of stored food material in cuttings. There fore use of neutral medium in Poly Green House is appropriate. Due to its inertness development of algae and fungi does not occur in humid environment.


IDEAL NUTRIENT MEDIUM   :-


                                                             After rooting saplings need nutrient for their growth. Ideal soil nutrient mixture is prepared by mixing soil, rice husk, vermin compost in a ratio of 1:2:2 mixtures. By so formed 1.0 cmt. mixture we can fill 6666 root trainer cells of capacity 150 cc can be filled by one cubic meter mixture.

 ADVANTAGES OF HI TECH NURSERIES

Less expense is involved in controlling insect-pests and diseases in nursery beds. Undesirable seedlings can be discarded at the time of transplanting.


Availability of sufficient time for field preparation, manure and fertilizer application after harvesting the previous crop.

Recent Advances in Hi-Tech Vegetable Nursery Production


  1. Vegetable nursery production has become a highly commercialized business, wherein most farmers buy their plugs from professional growers. 

  2. vegetable nursery is a place or an establishment for raising or handling of young vegetable seedlings until they are ready for more permanent planting. 

  3. The seeds of some vegetables are first sown in the nursery beds and the seedlings from these beds are later transplanted in the main field.

CONCLUSION :

       The  main purpose of this nurseries is to 

  • Maintain a good quality of plants 

  • protect the plants from pests and diseases.

  • Economy of land usage (duration in the main field is reduced)

  • Valuable and very small seeds can be raised effectively without any wastage .

GRAFT OR BUD UNION Author:- S.Hemanth

Physiology of graft (or) bud union formation   Article by:- S.Hemanth A. Characteristics of a functional graft union  Mechanical strength  Initially some sticking together of scion and stock is achieved by intercellular adhesion at first and intermingling of callus subsequently, but ultimately it is the interlocking of xylem fibers (wood) that results in a strong, permanent graft union.  Translocation   The structural integrity of the graft union not only holds the grafted plant together, but it is the reestablishment of anatomical and functional continuity between xylem and phloem that allows for translocation of water and minerals by the xylem, and conduction of carbohydrates and other organics by the phloem.    B. Sequence of graft union formation  Necrotic plate  The necrotic plate is a layer of desiccated, crushed cell walls at the cut surface of both stock and scion. Suberin (a waxy material) and pectin...
