Abstract: Farm saved seed (FSS) is commonly used to raise the next crop in predominantly rainfed Jharkhand. Though the organized seed sector is able to produce seed in large quantities, presently, in Jharkhand, the supply chain is unable to cope with the huge demand for seed (approximately 75 percent of the planting material used in the state is farm saved seed). Due to predominance of rainfed agriculture, poor infrastructure, monocropping, undulated topography, inadequate seed availability including seed cost and poor technology adaptation etc., the seed replacement rates of cereals, pulses and oilseeds, except rice, in the state are poor. This paper attempts to analyse the seed requirement of different crops in Jharkhand state. It discusses the constraints and strategies to enhance seed replacement rates (SRRs) including the impact of SRR on crop productivity. Due to improved varietal replacement rates (VRRs) and SRRs in Jharkhand state, the average productivity increased by 27.9 percent in rice, wheat (13.9%), pulses (18.3%), and in oilseed by 29.6 percent during 2007-08 to 2014-15, over the base year 2006-07. This signifies the critical role of both VRRs and SRRs in enhancing production, which should contribute to improving food security in Jharkhand.
