quality cane seeds, farm implements and drip irrigation under two schemes, namely, Sugarcane Development Programme under the state plan and Sustainable Development of Sugarcane Based Cropping System under the centrally sponsored plan.
State government is now putting emphasis on development of horticulture. Hill tracts of KBK districts and of Phulbani and Gajapati districts have been identified as suitable regions for cultivation of commercial fruits, use of hybrid vegetable seeds, propagation of off-season vegetable cultivation and the like. Oil palm plantation and use of drip irrigation are being given priority during Ninth plan.
INTER-DISTRICT AND REGIONAL VARIATIONS
It is observed that there are wide variations in agricultural performance in Orissa across zones and districts. There are broadly four agro-climatic zones in Orissa : Northern Plateau, Central Table Land, Eastern Ghat and Coastal Plain. Though Orissa has 30 districts since 1993, we have presented the data for the old undivided 13 districts for the purpose of showing changes in different agricultural indicators over time. Table 4.7 shows that during 1998 yield rate of foodgrains was the highest in Coastal Plain followed by Central Table Land, Eastern Ghat and Northern Plateau in that order. Interdistrict variations in yield rate of foodgrains show that it ranges from the highest 1279 kg/ha in Ganjam to the lowest 590 kg/ha in Kalahandi. Irrigation is the most important determining factor of agricultural productivity. Percentage of gross cropped area irrigated is the highest, 69 per cent, for Cuttack district and the lowest, 25 per cent, for Kalahandi.
To depict the district-wise agricultural development disparity scenario, composite Agricultural Development Index (ADI) have been constructed by ‘Deprivation Method’ by using nine agricultural development indicators, such as (i) % cultivable land to total land area, (ii) % area sown to total cultivatable area, (iii) % irrigated area to GCA, (iv) cropping intensity in %, (v) % GCA under HYV rice, (vi) fertiliser consumption per hectare of GCA, (vii) total road per 100 sq. km of area, (viii) per capita credit to agriculture and, (ix) average yield of rice (Table 4.8).
A careful analysis of the computed ADIs for different districts reveals that the four coastal districts (Balasore, Cuttack, Puri and Ganjam) and two districts of Central Table Land Area (Sambalpur and Bolangir) are agriculturally more advanced than other districts; as they have always occupied the first six positions in the three reference years over three decades (1980-81 to 1998-99). All the above districts have exchanged the first six ranks among themselves during the reference years. The agricultural success of four coastal districts is due to well-developed irrigation facilities and vast tracts of plain and fertile land comprising alluvial soil. Districts of northern plateau zone namely Mayurbhanj, Keonjhar and Sundergarh, and Koraput of eastern ghat area are found to be the most backward districts as they have secured the lowest ranks during the reference years. A significant proportion of gross cropped area in these districts is under rainfed agriculture and, thus, drought prone. Phulbani is the only district having sliding or worsening agricultural development index over the reference time period.

1 . The component indices are constructed by using the following formula:
where Iij = component index for the jth district with respect to the ith variable.
Xij = actual value of the jth district in the ith variable.
min Xij and max Xij are the minimum and maximum value of the ith variable.
2. After calculating the component indices the agricultural development index is constructed by using the following formula:
where Ij = the index of the jth district. Here, equal weights are given to all the indicators
However, it is heartening to note that the co-efficient of variation (C.V) in ADI values of districts is gradually declining over time. In 1980-81, C.V was 54.06 %, which decreased to 48.19% during 1990-91 and to 41.99% during 1998-99. From this it may be inferred that with passage of time the inter-district agricultural disparity in Orissa has declined.
The next logical step is to probe into the causes for inter-district variations in agricultural performance in Orissa. To identify such factors responsible for variations in agricultural productivity across districts we have estimated a regression equation as mentioned below.
