Constraints faced by onion growers in Perambalur district of Tamil Nadu: An empirical assessment
Abstract
Onion (Allium cepa L.) is an economically important vegetable crop in India and occupies a significant position in Tamil Nadu, particularly through the cultivation of small onion. Perambalur district is one of the important onion-growing regions of the state. However, onion growers face several production and post-harvest constraints that adversely affect productivity and profitability. The present study was undertaken to identify and rank the major constraints faced by onion growers in Perambalur district of Tamil Nadu. An ex-post-facto research design was adopted, and Perambalur district was purposively selected based on its importance in onion cultivation. A multistage sampling procedure was followed, involving the random selection of three blocks and eight villages, from which 120 onion growers were selected through simple random sampling. Data were collected through personal interviews using a structured interview schedule and analysed using appropriate statistical techniques. The findings revealed that high labour cost was the most prominent constraint, reported by 93.33 Per cent of the respondents, followed by high post-harvest losses (88.33 Per cent), shortage of labour during cultivation (87.50 Per cent), lack of proper storage facilities (85.83 Per cent), and difficulty in obtaining labour during harvesting (82.50 Per cent). Climate-related problems, pest and disease incidence, high input costs, irrigation-related constraints, and non-availability of quality planting materials were also reported by a substantial proportion of farmers. The study emphasizes the need for labour-saving technologies, improved post-harvest and storage infrastructure, efficient water management, timely availability of quality inputs, and need-based capacity-building interventions to strengthen onion production and profitability in the district.

Introduction
Onion (Allium cepa L.) is one of the most important bulb crops cultivated and consumed worldwide. In India, onion occupies a prominent position among vegetable crops owing to its high domestic consumption, market demand, and economic importance to farming households. The crop is cultivated extensively across different agro-climatic regions and is grown during both kharif and rabi seasons. Tamil Nadu is an important onion-producing state, with small onion occupying a particularly significant position among vegetable crops. Small onion serves as an important source of income for farmers in several districts of the state. Among the major onion-growing regions, Perambalur district has considerable importance owing to its substantial area under small onion cultivation and favourable conditions for onion production. Despite its economic importance, onion cultivation is associated with several production, labour, climatic, pest and disease, irrigation, input supply, harvesting, storage, and marketing-related challenges. These constraints can increase the cost of cultivation, reduce yield and quality, and contribute to post-harvest losses. Identifying and prioritizing these constraints is therefore essential for developing appropriate interventions and extension strategies. Against this background, the present study was undertaken to identify and rank the major constraints faced by onion growers in Perambalur district of Tamil Nadu.
Objectives of the Study
The study was undertaken with the following objective: 1. To identify and rank the major constraints faced by onion growers in Perambalur district of Tamil Nadu.
Research Methodology 3.1 Research Design
An ex-post-facto research design was adopted for the study, as the characteristics and conditions under investigation had already occurred and could not be manipulated by the researcher.
Selection of the Study Area
Perambalur district was purposively selected as the study area www.extensionjournal.com because of its importance in onion cultivation. The district represents an important production region for small onion in Tamil Nadu.
Sampling Procedure
A multistage sampling procedure was followed for the selection of respondents. Three blocks and eight villages were randomly selected. From the selected villages, 120 onion growers were chosen through simple random sampling and constituted the sample for the study.
Data Collection
Primary data were collected through personal interviews using a structured interview schedule developed for the study. Information provided by the respondents was cross-checked wherever necessary to ensure consistency and reliability.
Data Analysis
The collected data were tabulated and analysed using appropriate statistical techniques. Pearson's correlation coefficient was used to examine the relationships between selected independent and dependent variables, while multiple regression analysis was employed to determine the contribution of selected independent variables. Statistical analysis was carried out using SPSS.
Results and Discussion
The major constraints reported by onion growers were ranked based on the number and percentage of respondents experiencing each constraint.
Input-related constraints
The high cost of onion seeds/bulbs was reported by 92 respondents (76.66 Per cent). The increasing price of quality planting material can raise the initial cost of cultivation and may particularly affect small and marginal farmers. Delay in the availability of farm inputs was reported by 88 respondents (73.33 Per cent). Farmers indicated that essential inputs such as quality seeds and bulbs, fertilizers, pesticides, biofertilizers, and crop-protection materials were not always available at the required time.
The high cost of pesticides was reported by 85 respondents (70.83 Per cent), while the high cost of fertilizers was reported by 82 respondents (68.33 Per cent). These costs increase the overall financial burden associated with onion cultivation. Non-availability of quality seeds/bulbs was reported by 75 respondents (62.50 Per cent), indicating difficulties in obtaining good-quality and disease-free planting material at the right time and in sufficient quantities.
Soil fertility constraints
Soil fertility problems affecting production were reported by 90 respondents (75.00 Per cent). Continuous cultivation, repeated use of chemical fertilizers, inadequate application of organic manures, and improper nutrient management may contribute to nutrient depletion or imbalance. Maintaining soil fertility through balanced and appropriate nutrient management is therefore important for sustaining onion productivity.
Overall Ranking of Constraints
The findings demonstrate that onion growers face a combination of economic, labour, post-harvest, climatic, biological, irrigation, soil fertility, and input-related constraints. Labour and post-harvest issues were particularly prominent. High labour cost occupied the first rank, followed by post-harvest losses and labour shortage during cultivation.
Conclusion
The study reveals that onion growers in Perambalur district face multiple constraints affecting the productivity, quality, and profitability of onion cultivation. High labour cost www.extensionjournal.com emerged as the most serious constraint, followed by postharvest losses, shortage of labour during cultivation, inadequate storage facilities, and difficulty in obtaining labour during harvesting. Climate variability, pest and disease problems, irrigation constraints, high input costs, soil fertility issues, and inadequate availability of quality planting materials were also important concerns.
