RESEARCH PROPOSAL ON :COMPARATIVE ANALYSIS ON THE
RETURNS ON CABBAGE PRODUCTION UNDER ORGANIC AND INORGANIC
“A CASE STUDY AT VVU TECHIMAN CAMPUS”
AGYEMANG OSEI MARGARET
OUTLINE OF PRESENTATION
AIMS AND OBJECTIVES
*Cabbage(Brassica oleracea) is a leafy green crop with a short, thicken stem
surrounding by a series of overlapping expended leaves which form a compact head.
*Cabbage are grown as annual vegetable for it dense and leafy head, it has traditionally
been used for medicinal properties as well as for food.
*There several varieties of cabbage which includes stone head , earlina, two seasons
*The cultivation of cabbage required properly supply of plant nutrients. The
requirements of these plants nutrients can be provided by applying inorganic ,organic
or both fertilizer combination.
* It is an establish fact that the use of inorganic fertilizer for cabbage production is not
good for heath because of the residual effect and also its quite expensive to obtain the
fertilizer but for the case of organic fertilizer such problem doesn’t arises and on the
other hand increases productivity of the soil as well as crop yield[Tindal 2000].
*However ,farmers are now showing interest in organic
fertilizer rather than inorganic fertilizer because, they are
more aware about the residual effect of the chemical
substances used on the field and environmental
* Growth of cabbage under organic, inorganic
And both fertilizer application will be compared.
STATEMENT OF THE PROBLEM
*The problem of the study is to examine the reasons why
farmers are now changing form inorganic fertilizer to organic
fertilizer , and to analysis the returns on various fertilizer
applications on cabbage production
MAIN AND OBJECTIVES
*To evaluate the cost and returns associated with the
use of organic and inorganic fertilizer application on
*To identify the inputs used in the production of cabbage.
*To determine the cost associated with cabbage production.
*To estimate the returns obtained from cabbage production per
acre of land.
*To evaluate the different in net returns under organic and
inorganic fertilizer application on cabbage production.
*Cabbage (Brassica oleracea) is believed to have originated
from Western Europe and was first Cole crop to be
*Cabbage belongs to the Brassicacae family.
*There are three types of cabbage head namely, green , red
and savoy being the superior(Peirce 1987).
*Cabbage has high nutritive value, supplying essential
vitamins and protein ,carbohydrates and vital
*Cabbage is a heavy nitrogen feeder(Tindall,1979) and
therefore prefers deep fertile soil with PH 5.56.5(Askew 1992a)
*The best soil type for cabbage production is the sandy
loam soil or moisture-retaining soil.
*Serves as a source of food, which supply the body with
*It helps to prevent obesity, heart disease and
*Serves as source of employment to people.
*Generation of income.
PEST OF CABBAGE
*Cabbage web worm
*Caterpillars of diamond back moth
DISEASES OF CABBAGE
*Black leg disease

MATERIALS AND METHOD
For successful production of cabbage, the following materials will be
*Land for the production
*cabbage Seeds( Earlina )
*Inorganic fertilizers(N.P.K 15-15-15)
*Organic fertilizers(Poultry dropping's)
*Weedicides and pesticides
*Nursery bags(7 by 9)
Three treatments will be use
They are as follows;
*T1 –organic fertilizer
*T2 –inorganic fertilizer
*T3 – combination of both organic fertilizer and inorganic
The one variety to be used are as follows;
*One variety will be used with 3 treatments and 3
replications under the randomized complete Block
*The treatment will be V1T1,V1T2,V1T3.
V1T1-Earlina with organic fertilizer.
V1T2-Earlina with inorganic fertilizer.
V1T3-Earlina with both organic and inorganic fertilizer.
The data collected from the various plots will be
analyzed using the analysis of variance(ANOVA)
SOURCES OF VARATION
DEGREE OF FREEDOM
Income statement analysis, will be use to evaluate the
difference in net returns on various fertilizer application
on the cabbage production.
*Nursery bags will be use for the nursery of the cabbage
seeds. The nursery bags will be filled with top soil.
*Two seeds will be drop into each nursery bag.
*When the seedlings emerge and are about 2.5cm tall,
thinning out will be done, keeping the healthiest looking
*The cabbage seedlings will be ready for transplanting
when they are about 7cm tall.
*The land would be cleared three weeks before
transplanting and the ground must be ploughed deeply,
immediately before planting
*Transplanting space will be 50cm between rows and
40cm within rows because of it large headed cultivars.
*The purpose of the weeding is to control weeds that
compete with the cabbage for nutrient and prevent the
spread of diseases and pests attack
Three forms of fertilizers that will be applied to the cabbage
production are the organic, inorganic and both organic and
*Inorganic fertilizer(NPK15,15,15 )applied at 120kg/a.
*Organic fertilizer (poultry droppings),1t/a of processed
poultry manure, as sole source of nutrients for cabbage
*Cabbage requires a lot of water especially at the
* Watering will be done frequently for the plant to
obtained adequate water for growth.

DATA TO BE COLLECTED

*It is expected that, inorganic produce cabbage will
yield more and have higher returns than organic
The expected results from the project is foreseen to
help improve the production trend of cabbage in
