Unit V: VEGETABLE NURSERY ESTABLISHMENT TECHNIQUES Flashcards
is a place where young plants are raised under intensive care before
transplanting into the field.
Nursery
Advantage of Nursery
a) Economy of seeds
b) Uniformity of growth
c) Selection of seedlings
d) Better care of seedlings
Disadvantage of Nursery
Cost Labour
In selecting site a site for establishment of a nursery, a number of factors must be considered
Water Supply
Accessibility
Slope or Land Gradient
Soil
Labour Supply
is used for clearing the nursery site. It may also be used for transplanting seedlings and digging holes.
Cutclass or Machite
It is mainly used for making heaps, ridges and nursery beds. It is also very effective for turning up the soil, loosening the soil surface and to destroy weeds.
Hoe
It is used for transplanting seedlings from the nursery to the field and for
spreading manure and also for digging shallow holes on the beds.
Hand Trowel
It is used for turning manure during compost making and for spreading
manure in the open field. It is also used for loosening the soil before transplanting.
Garden Fork
It is used for digging and uprooting small stumps
Digging Mattock
is used for leveling soil surface and breaking large soil crumbs into small
ones. It is also used for removing stones and weeds from seedbeds and for covering vegetable seeds when they are broadcast.
Rake
It is used for lining up beds and for making straight line when planting.
Garden Line
It is used for sprinkling water over young seedlings and for irrigation
during dry season farming.
Watering Can
is used for taking short or detailed measurement on the field.
Tape
It is used for marking surveyed stations or intermediate stations. It is also useful in marking straight lines
Ranging Pole
It is often necessary to remove the vegetation cover when a piece of land is to be used for vegetable production.
Clearing
When the site has been cleared, uneven land may have to be leveled. This facilitates the process of ploughing, harrowing ridging and layout of the site.
Leveling
is the term used for manual or mechanical manipulation of the soil to prepare it for use in crop production.
Tillage
provides an environment in which a seed can germinate and grow. It is loose, well drained, deep enough, makes good contact with the seed, retains adequate moisture and is free of weeds.
Seed bed/Seed Bed Preparation
The soil surface after tillage may be such that it impedes run off. Stubble may be incorporated or ridges constructed to curb erosion
Erosion Control
Most suitable land for vegetable growing in the humid tropics is usually sloppy. When such
site has to be used for growing vegetables, soil conservation measure must be carried to prevent top soil from being washed away. A
Conservation Measure
This is the most traditional methods used in the prevention of erosion and is effective on land which has a fairly steep slope. It is obtained by constructing flat areas along the main contours of the
land.
Terracing
These are planted to prevent exposure of the soil from direct solar radiation and falling rain
when any part of the farmland is not used for planting.
Cover Crops
The cultivation of different types of crops in narrow strips usually on steep slope or hill side
to maintain
Strip Cropping
