The present study is an attempt to highlight the cost-benefit analysis of mustard crop and need of organic farming in village Charkhi of district Charkhi Dadri of Haryana. The study is primarily based on primary data but for physical and socio-economic aspects of the village secondary data are also utilized. The primary data regarding various agricultural operations or activities like land preparation, sowing, irrigation, fertilizer application, weeding, pesticide spray, harvesting, threshing, transportation and marketing of the produce under mustard cultivation is collected from the farmers of this village through a field survey conducted in 2018 under which structured interview method was adopted. A comparative study regarding the cost-benefit analysis for mustard cultivation per acre of land is exercised both in case of self/family members, and the hired labour cost involved in mustard cultivation in this village. The study highlights that mustard cultivation is more beneficial in case of cultivation done by landlord (self/family members) than hired labours. The benefits can be more if organic farming is promoted in this area as this practice is cheaper than the conventional method of cultivation.
