It is an attempt to draw a clear picture of development disparities among the districts of Assam in agriculture with the help of composite index. Eighty-three indicators are considered here which are directly related to the agriculture. On the basis of these indicators Nagaon, Borpeta, Dhubri and Kamrup are developed districts but Karbi Anglong, Hailakandi, Dhemaji and N.C. Hills are low developed districts. The developed districts cover 18.31 percent areas and 30.47 percent population of the state whereas low developed area covers 25.35 percent areas and 7.94 percent population of the state. The entire agriculture sector is divided into seven sub sectors namely Production of miscellaneous crops, Production of pulse, cereals and oil seeds, Fertilizer used, and Percentage of livestock population, Rice production, Fish production and Infrastructure facilities. In each sector developed and low developed districts have been identified. In crop production Kokrajar, Dhubri and Sonitpur are high-developed, Jorhat, N.C. Hills and Nagaon are low developed. In production of pulse, cereal and oilseeds Goalpara, Sonitpur, Bongaigaon and Karbi Anglong are developed districts and Nagaon, Tinsukia, Karimganj, Jorhat and Morigaon are low developed districts. In case of livestock population Jorhat is the developed district and Dhemaji, Hailakandi and N.C. Hills are low developed district. In fish production Nagaon, Borpeta, Cachar and Karimganj are developed districts and Karbi Anglong and N.C. Hills are low developed districts. In case of rice production Golaghat, Karimganj, Hailakandi, Sibsagar, Dibrugarh and Cachar are high developed and Bongaigaon, Borpeta, Nalbari, Dhemaji and Lakhimpur are low developed. In case of infrastructure facilities e.g. irrigation, use of electricity in agriculture etc. are availed by the districts Nagaon, Nalbari, Borpeta and Kamrup are high developed and Hailakandi, Dhemaji, N.C. Hills are low developed. From the study it also reveals that the districts, which are low developed in overall agriculture sector they are also low developed in using infrastructure facilities essential for agriculture except Karbi Anglong. For bringing the uniform development in the state, model districts and potential target for low developed districts have been identified.
