This document presents a research proposal on the effects of organic and inorganic fertilizers on radish production. The study will be conducted at Valley View University's Techiman campus in Ghana. The researcher aims to evaluate the impact of different fertilizer regimes (organic, inorganic, and a mixture) on radish yield and cost. Two radish varieties will be grown under various treatment conditions in a split plot field design. Data on plant growth, flowering, yield, and costs will be collected and analyzed to determine which fertilizer application maximizes radish production. It is expected that a mixture of organic and inorganic fertilizers will yield the highest returns.

5. INTRODUCTION
(Raphanus sativus) is an edible root vegetable of the
Brassicaceae family that was domesticated in Europe,
in pre-Roman times.
Radish were originally cultivated in China.
There are quick –growing spring type radishes and
slow –growing summer and winter radishes.
Like other brassicas,radishes contain mustard oils
which give them pungency.
6. INTRODUCTION
Diakons are a long white Asian type of winter radish.
Radish leaves are deeply pinnate and form a basal
rosette.
Most radishes produce a flower stalk in cool
temperatures followed by long days of initiate
bolting.
They are grown and consumed throughout the world.
Radishes have numerous varieties, varying in size,
color and duration of required cultivation time.
7. INTRODUCTION
Radish is a good source of :
Vitamin C which powers human immune system and
keeps the skin youthful.
Potassium.
Magnesium and
Trace amounts of other nutrients.
Four radishes supplies 5 kilocalories.
Red radish are low in calories
8. PROBLEM STATEMENT
There is however a knowledge gap as to which type
of fertilizer use will bring out a maximum yield of the
crop in this region of the country.
9. AIMS AND OBJECTIVES
MAIN AIM
To assess the effect of various fertilizer regime on
radish production.
SPECIFIC OBJECTIVE
To evaluate the effect of organic and inorganic
fertilizer on radish production in terms of their cost
and yield.
10. LITERATURE REVIEW
Flowering or bolting in annual radishes can occur
after roots reach edible size and the plant is exposed
to warm temperature.
Radish is a quick growing cool season root vegetable.
The seed will germinate in 3 to 4 days with soil
temperatures of 18 to 30 C with good moisture.
The best quality and root shape are obtained when the
crop grows and matures at moderate temperatures (10
to 18 C) in intermediate to short day lengths.
11. LITERATURE REVIEW
Once the plant produces a flower stalk ,radish
flavor and quality deteriorate.
Radish flowers are insect pollinated. Root crops grow
best on fluffy soils with good tilth.Radish crop can
tolerate a wide pH range of 6.0-7.0.
This crop requires a well drained sandy loam or loam
with a good supply of organic matter as well as an
even moisture supply for good quality (mild, tender
and attractive).
12. LITERATURE REVIEW
Rocky or gravelly soils are generally not acceptable
especially if bed harvest is to be used. Peat(Partially
carbonized vegetable matter saturated with water) is
suitable for production of radish.
Planting deeper then produces elongated roots.
Planting depth should be 0.5 to 1 cm, Spacing, rows
should be 20 to 30 cm apart.
Irrigation should be frequent and uniform to ensure
good growth.
13. METHODOLOGY
MATERIALS AND METHOD
MATERIALS NEEDED.
For successful production of Radish, the following
materials will be obtained.
Land for production.
Radish seeds namely (Cherry Belle and Daikon Long
White)
Inorganic fertilizer(N.P.K)
Organic fertilizer.(Poultry Manure)
14. MATERIALS AND METHOD
Irrigation system.
Weedicides and pesticides.
Knapsack sprayer.
The two varieties to be used are as follows;
Cherry Belle
Daikon Long White.
NURSERY
The seeds will be nursed until they are ready for
transplanting to the field when soil conditions are
favorable for easy establishment of the seedlings.
15. MATERIALS AND METHOD
SOIL PREPARATION
Fields will be prepared thoroughly by plowing and
harrowing ,removing the different types of plant debris.
WEEDING
The purpose of the weeding is to control weeds that
compete with the crops and prevent the spread of
diseases and pests.
Two (2) weeks after transplanting, the first weeding is
done and the second weeding is done from 6 weeks.
16. MATERIALS AND METHOD
FERTILIZATION
The two forms that will be employed to amend the radish
production are the organic and the inorganic fertilizers.
Apply ¼ cup per 10 foot of row of a nitrogen-based fertilizer
(21-0-0) after emergence to encourage rapid plant growth.
Place the fertilizer to the side of the plants and irrigate it into
the soil.
IRRIGATION
The radish plant will be watered on 2 times daily (morning and
evening).
Water holes or watering can will be used as a means of
irrigation to the radish plants.
17. MATERIALS AND METHOD
DATA TO BE COLLECTED
Plant height.
Number of leaves per plant.
Time of flowering initiation
50% flower initiation.
Full flower initiation.
Number of flowers per plant
18. MATERIALS AND METHOD
DATA TO BE COLLECTED
Date of harvesting.
Cost of fertilizers.
Cost of labourers
Cost of land preparation
19. MATERIALS AND METHOD
The four treatments are as follows;
T1 – No fertilizer.
T2 – Inorganic fertilizer.
T3 – Organic fertilizer.
T4 –Mixture of organic and Inorganic fertilizer.
The two varieties to be used are as follows;
V1 – Cherry Belle
V2 – Daikon Long White
20. MATERIALS AND METHOD
TREATMENTS
Two(2) varieties (Cherry Belle and Daikon Long
White) will be used with 6 treatments and 3
replications under the Split Plot Block Design.
The treatments will be V1T1, V1T2, V1T3, V1T4,
V2T1, V2T2, V2T3, V2T4 because of the two
varieties.
21. MATERIALS AND METHOD
V1T1 – Cherry Belle with no fertilizer.
V1T2 – Cherry Belle with inorganic fertilizer.
V1T3 – Cherry Belle with organic fertilizer.
V1T4 – Cherry Belle with mixture of organic and
inorganic fertilizer.
V2T1 –Daikon Long White with no fertilizer .
V2T2 –Daikon Long White with inorganic fertilizer .

25. EXPECTED OUTCOME
• It is expected that, Radish that would be grown under
the mixture of the organic and inorganic fertilizers
will yield more than the organic and the inorganic
fertilizer since the nutrients will be more readily
available and adequate for the Radish growth and
yield.
