cartographically represented Weavers

(1954) crop combinational analysis and Rafiullah’s (1956)

maximum deviation method of crop combination analysis. Were applied and crop combination regions of Tamilnadu is brought out through using MapInfo, GIS software modules.

3.1 Crop combination regions in Tamilnadu 3.1.1 Introduction Cropping pattern is closely linked with the stage of agricultural development and is considered as a measure of agricultural development of the area. In the present study an attempt has been made to identity the crop regions in the state to understand the existing cropping pattern. The important crops of food and non-food crops have been used for the analysis. The % area under these crops has been arranged descending

in

order and using combination analysis identifies the crop regions. The analysis carried out at

district level. And Weavers method of combination analysis and Rafiullash’s maximum deviation method are employed to identify the existing crop regions of Tamilnadu.

3.1.2 Ranking of crops For the purpose of analyzing the crop combination ranking of crop on the b asis of total cropped area where used t identify the ranking of crops which are dominates in one or more districts of the state. There are 12 crops occupies maximum percentage of total cropped area. Other crops are grown in combination with major crops. The first rank crop may vary from 100% to 40%. The 12 ranking crops are (i) Paddy (ii) Cholam (iii) Cumbu (iv) Pulses (v) Groundnut (vi) Sugarcane (vii) Cotton (viii) Turmeric. These crops have 10 macro crop combination regions. The following table No: 3.1gives the ranking of crops in different districts of Tamilnadu.

3.1.3 Crop combination regions Application of Weavers method gives 7-crop combination for the state of Tamilnadu. The districts falling into different crop association of given are in table No: 3.2 and Fig No:3.1. According to this classification there are mono crop region and two crop regions in the state of Tamilnadu. The districts of Kanchipuram, Sivagangai, Ramnad and Nilgiris have mono crop region. Where Paddy is a single crop in the entire district except the Nilgiris where tea is cultivated as mono crop. Two crop regions are Thiruvallur, Tiruvarur, Nagapattinam, Madurai and Thirunelvelli, wh ere Paddy, Turmeric and Pulses constitute to form two-crop combination. These two-crop combinations are found in coastal plains. Where irrigation facility are available. The climate and soils are best suited for these crops. These are the crop they are permanent crops and mostly crop rotation is mostly absent in these areas. There are 4 district has three crop combination. The constituent crops are Paddy, Pulses, Cotton, and Coconut. These all the areas falls on the upland and plains of Tamilnadu. The soils found in these areas are red soil and suited for cultivating these crops. Four crop combination is found in 3 districts of Tamilnadu in association of 6 crop of different combinations combined and grouped to make 4 crop combinations. Paddy, Pulses, Cholam, Coconut, Fruit and Vegetables and Sugarcane constitute to form combination. This type of combination is confined only in Eastern part of Tamilnadu. Here red soils with moderate retention capacity resulted diversification of crops. There are 8 districts have 5 crop combination. Crops like Paddy, Sugarcane, Cholam, Pulses, Fruits

and Vegetable’s, Cotton, Ragi, Groundnut, made 5-crop combination. The districts fall on this group is found in central upland area except Thanjavur where tank irrigation and rainfall are dominated factors in determining the crop combinations. Only two districts have 6-crop combination Ragi, Paddy, Cholam, Cumbu, Sugarcane, Cotton, and Coconut. Constitute 6-crop combination. These 2 regions found only on Northern part of Tamilnadu.

Here variability of rainfall is very high and soil is red. This resulted

diversification of crop in this area. 7 crop region is found in 2 districts of Tamilnadu in association of Paddy, Groundnut, Cholam, Cotton, Fruits and Vegetables, Sugarcane, Maize, Turmeric, Ragi, Coconut, Pulses, Cumbu are combined and grouped to make different combination in these two district. These combinations are mainly found in dry areas where deficiency of rainfall is noticed.

3.2 Rafiuallah’s crop combination regions The defect over generalization in Weavers method of crop combination is rectified through the method adopted by Rafiullah (1950). The insignificant crops are avoided from being brought in to crop combination by applying maximum deviations method. 4 crop combination regions in Tamilnadu and are plotted in the following figures and tables. Single crop or monoculture dominance is found in 17 districts out of 28 districts of Tamilnadu.

Mono culture of Paddy, Groundnut, Pulses, Fruits and Vegetables, Cumbu are found in most of the district out of 17 blocks Paddy is cultivated as single crop.

Pulses are dominant in 2 districts and Groundnut,

Fruits and Vegetables is grown as mono crop in Theni district. Two crop combinations are found in 8 districts of Tamilnadu and are found in coastal areas and on upland areas of Tamilnadu, where Paddy and Turmeric, Pulses, Ragi, Groundnut, Paddy and Pulses formed in 2 crop combinations Tiruvarur and Madurai.

Paddy and Turmeric constituted two-crop combination in Kanchipuram, Thiruvallur and

Villupuram. Fruits and Paddy formed in Nilgiris 3 crop Paddy, Cholam, Cotton, Fruits and Vegetables, Pulses grouped to form 3-crop combination region. Paddy Cholam, Cotton constitutes 3 crops in Trichy. Only one district of Tamilnadu, Nagapattinam has 4-crop region. Paddy, Pulses, Sugarcane, Coconut constitute 4 crop combinations. This region experience very high rainfall has well drained alluvial soils. Table 1: Weaver’s crop combination regions

4. Summary and conclusion The change in the cropping pattern and introduction of crop in relation to agro climatic condition can provide high standard of productivity. To determine the region character of crop distribution various method of analyzing cropping pattern is made to bring out the regional dominates of crop. The study area Tamil Nadu located in southern most part of India experiences tropical monsoon climate. The state receives maximum rain fall during North East and South West Monsoon seasons with the availability of fertile soil like alluvial, block cotton and red soil variety of crops are cultivated. Nearly 50% of the total geographical area in Tamil Nadu is under cultivation. Forest occupies about 18% and other use occupies the rest of the area.

The principal crops such as paddy, Cholam, ground nut sugarcane and pulses are

cultivated. The analysis of area under different crops revealed that the paddy dominates as single crop in most of the district in Tamil Nadu. The ranking of crops data shows that paddy, ground nut, cumbu, cholam, fruits and vegetables cultivated as first crop in most of the districts. Out of 28 districts paddy is the mono crop in 17 districts followed by ground nut in 3 districts fruit and vegetable 3 districts. Turmeric, pulses, ground nut fruit and vegetables constituted to form 2 crop combination and as second crops in most of the district. According to Weaver’s method of crop combination analysis there are maximum of 7 crop combination region are in Tamil Nadu. To conclude, the analysis of crop combination and their association reveals that there are diversified cropping pattern in Tamilnadu.

Mostly 4-5 crop combinations are

identified in Tamilnadu. According to Weavers method of analysis there are 4-5 crop combination regions in Tamilnadu where as only 2 crop combination is dominance in Tamilnadu according to Rafiullah’s method of crop analysis. By applying Rafiuollah technique crop combination region of Tamil Nadu is brought into 4 combination regions. Mono cultural is dominated in 17th district of Tamilnadu followed by two crop region 8 districts. The analysis shows that there is no diversification of cropping pattern in most if the districts of Tamilnadu expect the centre and eastern part of the state. The crop like paddy and pulses constituted as two crop region in Tamil Nadu.
