The study also focussed on the economic analysis of carrot cultivation, resource use efficiency in carrot production and constraints faced by farmers in production and marketing of the carrot crop. The study is based on both primary and secondary data. For collection of primary data, a multistage sampling method was used which includes a sample of 40 farmers cultivating carrot from Haryana and 40 farmers cultivating carrot from Karnataka. The secondary data was collected for a period of 20 years from 2001 to 2020.The growth rate was estimated using compound annual growth rate, instability is measured using CDVI, contribution of area and yield on production is studied using decomposition analysis. The economics of carrot cultivation was calculated using various cost concepts as devised by CACP and B:C Ratio. Resource-use efficiency was measured by employing Cobb-Douglas production function and for constraints analysis Garrett’s ranking technique was employed. Results revealed that the growth rate in area and production carrot in India as well as in Haryana and Karnataka have increased with 7.62, 14.72, 0.81 and 7.57, 4.47, 0.46 per cent per year, respectively while productivity have decreased by -0.24, -0.24 and -0.38 per cent per year, respectively. The instability in area and production of carrot showed a higher degree of instability compared to productivity. The decomposition analysis showed that the area effect and yield effect were found to be responsible for increase in production of carrot in India as well as in Haryana. Whereas, in Karnataka, the yield effect was found to be responsible for increase in production of carrot, while area effect and interaction effect were responsible for decrease in production. In Haryana, the per hectare total cost of cultivation of carrot worked out was ₹219528. Farmers received a net return of ₹185238 with a B:C ratio of 1.84 per hectare. Similarly, the farmers growing carrot in Karnataka obtained a net returns ₹218941 per hectare and total cost of cultivation worked out was ₹358886 per hectare with a B:C ratio of 1.61.The returns to scale from carrot production in Haryana was found to be 1.03 and resource use efficiency of different inputs used in production was revealed as positive and greater than one indicating their under-utilization, except for the irrigation where it found to be positive and less than one indicating its over-utilization. The returns to scale from carrot production in Karnataka was found to be 0.54 and resource-use efficiency of different inputs used in production was revealed as positive and greater than one indicating their under-utilization, except for the input plant protection chemicals and human labour where they found to be positive and less than one indicating their over-utilization. The major constraints faced by farmers were, high cost of labour, scarcity of labour, attack of pest and diseases, high fluctuation in prices and lack of cooperative marketing system in village.EnglishThesis
