Background: Fodder cultivation has direct bearings on the production of milk by the dairy animals as it forms a major part of rearing cost incurred for milch animals. Several studies have pointed out the benefits of fodder cultivation, but the area under fodder cultivation is quite low; and its limited supply is hindering the milk productivity. Hence, the present study was undertaken to estimate the economics of fodder cultivation of kharif and rabi season in Punjab and Haryana as these two states have highest per capita milk availability in India. Methods: Primary data on fodder cultivation was recorded for the year 2019-20. A sample of 100 respondents were interviewed from Punjab (Patiala, Bhatinda, Amritsar and Ludhiana districts) and 100 were selected from Haryana (Hisar, Karnal, Kaithal and Panipat districts). Simple arithmetic mean and percentages were used in the study. Result: The output-input ratio for kharif and rabi fodder in Punjab and Haryana were found to be of 1.52 to 1.64 and 3.61 to 4.12. Since, majority of the farmers in these states follow crop and dairy farming system, due consideration should be provided to fodder cultivation as well.
