Differential adoption of plant protection technology by farmers of Kerala - a critical analysis

Abstract

Indian agriculture has undergone intensive farming with the introduction of high yielding varieties of crops. Adoption of improved technology and management practices for boosting up production of food grains have resulted in serious pest and disease complexes warranting intensive and extensive use of plant protection chemicals. A number of limitations and adverse side effects such as pest resistance to pesticides, pesticide residues, health hazards, environmental pollution and ecological imbalance have been identified recently.

The components of plant protection technology were taken to study the differential adoption in important crops like paddy and vegetables by the farmers and explained the variations in their cognitive, affective and connative components of behaviour with a selected set of independent variables. The study analysed the indigenous practices of plant protection being followed by farmers and also their perception about the impact of pesticides on environmental aspects. The major constraints experienced by the farmers in the adoption of plant protection technology along with the suggestions to overcome the same were also studied.

The study was undertaken in two districts of Kerala viz., Thiruvananthapuram and Alappuzha. A sample of 120 farmers each from the two districts was selected and the total sample size for the study was 240.The data were collected using an interview schedule and analysed using suitable statistical techniques.

There was significant difference among the farmers of Thiruvananthapuram and Alappuzha districts with regard to their knowledge about chemical and cultural methods of plant protection. Majority of farmers of both the districts belonged to low knowledge group. The farmers of both the districts were ignorant about biological, physical and integrated methods of plant protection methods. Majority of the farmers of both the districts possessed favourable attitude towards chemical method of plant protection. The farmers of Alappuzha district were significantly higher adopters of plant protection methods than the farmers of Thiruvananthapuram district. Majority of the farmers of both the districts belonged to low perception category with regard to their perception about the utility and practicability of plant protection methods. Crops yield index and scientific orientation emerged as significant independent variables in the correlation and multiple regression analysis with regard to the farmers of both the districts.

The practices, viz., controlled application of nutrients for reducing pest and disease attack in paddy and use of ‘thulsikeni’ in ‘pandals’ to trap and kill fruit flies in vegetables were judged as the most effective and scientifically rational practices adopted by farmers. The farmer’s perception about the impact of pesticides on environmental aspects was very low and majority of them belonged to low perception category.

The constraint ‘untimely supply and high cost of imputs’ was the most important constraint experienced by the farmers of Thiruvananthapuram district, while ‘lack of proper drainage facilities’ was the most serious constraint experienced by the farmers of Alappuzha District. The most important suggestion given by the farmers to overcome the constraints was to ‘develop simple and more compatible plant protection technologies’ and the most important suggestion given by the experts to overcome the constraints experienced by the farmers was to ‘impart adequate training to farmers as well as extension workers on IPM practices’.

The strategic model developed by integrating the salient findings of the present study, emphasized the importance of popularizing effective plant protection technology among the farmers in ecologically sensitive rice and vegetable production systems in Kerala.
