Abstract/ Executive Summary:

The study was conducted at Satkania, Patiya and Hathazari upazilas of Chittagong district during 2007-2008 to identify different pest problems and practices, input use and economic returns at farmers’ levels. Brinjal shoot and fruit borer, epilachna beetle, thrips and red mite were the key insect and mite pests for brinjal production in the study areas. Majority of the farmers of Patiya sprayed pesticides more than 45 times in brinjal cultivation. Pesticide dealers were the major source of information to farmers on the selection of chemicals and application methods. Very few farmers used protective measures or safety measures during pesticide application where 39% of the respondents did not use any safety measures. On an average 61% believed that pesticide application are harmful to farm labor. This study reflects the irrational use of pesticide in vegetables cultivation that has serious consequences to human health and environment. Study found that average gross margin was Tk 211331 and net return per hectare on the basis of full cost was Tk 205465 for brinjal production. It was also found that the average returns to labor was Tk 1046/man-day on full cost basis and Tk 1070/man-day on variable cost basis respectively.

Keywords: Economic Assessment, Brinjal Cultivation, Pesticide Use, and Chittagong

Location: The survey was conducted at three upazila namely Hathazari, Patiya and Satkania under Chittagong district

Start Date: 00-00-2007

End Date: 00-00-2008

Program Area: Socio-economic and Policy

Commodity: Brinjal

Objectives:

i) to know the socioeconomic characteristics of pesticide users

ii) to know the application of pesticides for brinjal cultivation

iii) to determine cost and return of the production of brinjal

iv) to observe the impact and implication of using pesticides

Methodology:

The survey was conducted at three upazila namely Hathazari, Patiya and Satkania under Chittagong district during 2007-08. Because of intensive brinjal cultivation in that upazilas a total of 120 farmers were selected purposively taking 40 from each study area. Simple random sampling technique was followed in selecting the sample farmers. Data were collected from the sample farmers during the period April to May 2008 through field survey using pre-designed and pre-tested interview schedule. The collected data were coded, edited for processing through tabular method using average, percentage and ratio etc.

Estimation of Gross Margin: The gross margin or the income above variable costs for each enterprise is needed to consider for selection of a crop. The higher the gross margin of the crop enterprise, the more it will be preferred (Gonzales et.al., 1986, Climents, 1985 and Mc Gillivary, 1961). The gross margin for a simple crop enterprise is the difference between total income and total variable costs. The cost of all inputs either it was home supplied or purchased, have calculated as cash cost or direct expenses. To determine the cost for home supplied inputs, opportunity cost concept was applied. The total income of brinjal is equal to output price time’s yield or production. Return to human labor is estimated by deducting all variable costs other than costs of labor from gross return and dividing the figure by numbers of man days (human labor) employed for brinjal production.

Achievement/Findings:

Brinjal cultivation is highly profitable on the basis of its returns to investment. The present study clearly demonstrated the indiscriminate, irrational and whimsical use of pesticides in brinjal cultivation. The existing excessive use of pesticide are causing different consequences like development of resistance power of pest, the killing of natural enemies which may again lead to the favorable condition for the development of pest population. This again results the disruption of agro-ecosystem, environmental pollution and serious threat to human health. Majorities of the farmers did not use biological and cultural methods. Very few farmers use simple sanitation method. Information dissemination through mass media should be undertaken on the successful and proper dose of pesticide use as well as the detrimental effect of pesticides use on brinjal cultivation.
