The fundamental work of primary sector is to covert natural resources into primary goods. This sector also provides raw material for industries. It is seen from the last few decades that despite the engagement of most of the population in primary sector the share of primary sector in SGDP of Jammu and Kashmir has been declining consistently. On the other hand cooperative societies have played a significant role in providing credit facilities to the farmers for improvement in agriculture. This paper examines the impact of working capital of central Co-operative banks, the Cooperative credit societies, Marketing societies and all other societies on the growth of Primary sector in Jammu and Kashmir. Over the years the state has witnessed immense growth in the cooperative sector. Empirical analysis results show that the increase in the level of agricultural loans granted by the cooperative banks and Agriculture Credit Societies has positive influence on share of SGDP of primary sector in Jammu and Kashmir. On the other hand, increase in working capital of marketing societies has negative impact on the share of SGDP of primary sector in Jammu and Kasmir.
