Seed is most important input in agriculture. It is cheaper than other critical inputs like irrigation, fertilizer and plant protection measures. Quality seed availability at proper time determines the agricultural growth rate of the state. The use of quality seeds with desirable replacement rate is essential for growth in productivity. The use of high yielding varieties of paddy and wheat had played as important role in green revolution. In previous years the growth rate in agriculture in the state is lower than the growth rate in population. To feed the increasing population it is essential to achieve larger growth in agriculture. Seed production could be a tool for growth in agriculture.

Seed market of the state is of about 100 crores of which 75% share goes to the producers of out side state. The share of certified seed requirement for wheat and paddy is 27% and 23% of total requirement of certified seed.

Seed replacement rate for different crops is between 15% to 70% in the state. Average seed replacement for the country is about 15% to 20%. Normally 25% replacement for self pollinated crops and 33% replacement for cross pollinated crops is considered appropriate for proper growth in agriculture. By using quality seeds and by proper replacement of seeds, as advised by the scientific community, sustained yields increases up to 20% may be ensured by the farmers. For self-pollinated crop like paddy, wheat, all pulses and oilseeds except rapeseed, mustard, sunflower and castor the seed must be replaced once in four years. Similarly, for cross pollinated crops like Jowar, Bajra, Maize, Castor, Sunflower, Rapeseed, Mustard, Cotton and Mesta the seed is to be replace one in every 3 years. For hybrids of these crops, the seed is to be replaced every season The immediate increase in productivity can be achieved by planning a higher seed distribution programme of newly/ high yielding and superior varieties/ hybrids which are recommended for the state but are not popular among farmers due to lace of awareness and extension work. it is needed to review and prepare a programme for achieving not only higher SRR but also for distribution of specific superior varieties/ hybrids of major crops so as to increase the average productivity of the state.
