The analysis of crop combination regions is important aspects of agricultural geography; it provides more information about agricultural regionalization. In Karnataka State crops are normally grown in combinations and are rarely they occupy isolation from other crops in a particular area at a particular time. In India generally a set of crops are grown so as to suit the environmental frame. Different types of crop grown avoid the risk of crop damages; verities of crop create high cropping intensity zones. Combinations of crops produce different types of crop. The study of crop combination is also very useful for the area development planning particularly for the rural areas. In recent period this crop combination concept gain more attention and become an important fact among geographers and agricultural planners.

Haveri district encompasses an area 4823 sq.km lying between the latitudinal parallels of 14⁰ 19' North to 15⁰ 19' North and the longitudes of 75⁰ 01' East to 75⁰ 50' East.Haveri district one of the newly formed district in Karnataka. It was carved out of the undivided Dharwad district on 24^th August 1997. Erstwhile Dharwad district was divided into three districts; Dharwad, Haveri and Gadag. Now Haveri district is surrounded by Dharwad district in the North, Uttar Kannada district in the west and Davanagere district in the South, Ballari district is towards East of Haveri district. Haveri district is located in northern semi rain fed and semi-malnadu zone.

Haveri district consists of 7 taluks namely Byadagi, Hangal, Haveri, Hirekerur, Ranebennur, Savanur and Shiggaon. For administration convenience two revenue sub-divisions have been formed in this district. While Haveri, Byadagi, Hirekerur and Ranebennurtaluks are the part of Haveri sub-division, the remaining Savanur, Shiggaon and Hangal are the part of Savanur sun-divisions. The district has 698 inhabited of which 7 uninhabited villages, 19 hoblies. This district also known as the Gateway of the Northern Districts of Karnataka.It isfamous for its Cardamom garlands. Jawar, cotton, rice, chillies, gram, groundnut, sunflower, sugarcane and oilseeds are the major crops of the district.

To know the agricultural aspects of Haveri district.

The present research has been done by using secondary data of District Statistical Handbook of Haveri district (2016-17) which is collected from department of economics and Statistics, Haveri district. In this study taluks has considered as the smallest unit of analysis. The crop combination pattern has been calculated by using the J.C. Weaver method which is expressed as, d=∑d2N

Where d means difference between standard value and actual value and N means number of crop in a given combination.

To understand the cropping pattern of the study region a comparison of relative position of a real strength of various crops is ascertained by ranking them for each taluk according to the percentage of each crop to the total cropped area. The first, second and third ranking crops thus obtained for each taluk is mapped with resulting pattern
