INTRODUCTION Cropping pattern define the proportion of various crops in an area of land at specific time period and also indicates the yearly sequence and spatial arrangements of crops and fallows in an area. Rotation of crops is the process of growing different crops in succession, on a piece of land, in a particular period of time. Cultivating the crops is the proportion of area with various crops, inclusive of changes over time and space. Cropping patterns of an area are closely influenced by the climatic, historical and socio-economic condition of the farmers and also terrain, topography, slope, soil condition and availability of water, as well as the pesticides, fertilizers and mechanization.

OBJECTIVES The main objectives of the present study are: To study the annual area variation of crops in the Hemavathi watershed. To study the area indices of the major crops in the study region. METHODOLOGY The cropping data was collected from district statistical offices, at Hassan, Mandya, Mysore, Chikkamagalur and Kodagu. This study is concentrate on major crops of the Hemavathi watershed, these crops are paddy, ragi, jower, maize, sugarcane, coffee and Tobacco. From the year of 2015-16 to 2018-19 crops cultivating area was used for full fill the objectives. The study region has been divided into three zones on the basis of climate, rainfall, temperature and elevation. STUDY REGION The Hemavathi River is a very important tributary of the Cauvery river. It starts in the Western Ghats at an elevation of about 1,219 meters near Ballala Rayana Durga in the Chikamagalur district of the state of Karnataka and flows through Chikamagalur, Hassan, Mandya and Mysore districts, before joining the Cauvery river near Krishnarajasagara. It is 245 km long and it has a drainage area of about 5,697.65 km2. A larger reservoir has been built on the river at Gorur in the Hassan district. In the entire Cauvery basin the Hemavathi watershed is second largest in terms of area.

Maximum decreases were recorded in the year 2011-12 in both the zones, whereas in zone three, the paddy area cultivation increased in the years 2009-10 and 2012-13 and decreased in the remaining years. This is because paddy requires more water but in the study periods gradually rainfall is decreasing although this area is irrigated by Hemavathi and Yagachi dams the water supply from these dams to agricultural crops is gradually decreasing. So the formers invariably instead of growing paddy they give preference for less water consuming crops like maize and other crops. Ragi Ragi is the second most important food crop in this region. In zone one, the ragi area increased from 2009-10 to 2012-13 and in zone three, also, it increased from 2009-10 to 2011-12. From 2012-13 onwards, the ragi cropping area decreased in both the zones. In zone two, the area’s growing ragi gradually decreased during the period of study, all though in southern Karnataka ragi is popular food crop this is because the per hectare yield of ragi is less when compare to other food crops as a result formers prefer to grow other commercial crops. Jowar Jowar is third important crop in this area. The jowar crop area clearly indicates that there is a tendency of both increasing and decreasing. In the zone one jowar area increases occurred from 2009-10 to 2015-16. After 2017, the total jowar area cultivation decreased. In zone two, the jowar area increased. The highest positive change is noticed in the year 201112 and the lowest positive change occurred in 2016-17. Maize In zone one, total maize crop area increased. The highest increase was recorded in the year, 2016-17. In zone two, also, there's an increase, except during the year, 2009-10. Beyond this year, the total area of maize was increased. The highest positive change in the area growing maize crops was found in 2017-18. In zone three, the maize crops in the area increased from 2014-15 to 2018-19 and decreased from 2009-10 to 2012-13. The greatest positive change, in the maize areas was observed in the year, 2018-19. The greatest negative change in the maize area was observed in 2011-12. The lowest negative change in this maize crop area occurred in 2012-13. Totally the area under maize is gradually increasing because it is less labour intensive as well as the use of maize is expanding because the by products Copyright © 2021, Scholarly Research Journal for Humanity Science & English Language

number from the maize is increasing day by day and also the cost for this crop is relatively less. Sugarcane Sugarcane is one of the commercial crops in this region. This crop is concentrated in zone one and zone two. In zone one, the area growing sugarcane has increased in 2012-13, but decreased in 2011-12. In zone two, the sugarcane areas changed both positively and negatively, from 2009-10 to 2013-14. The total area increased after 2013-14. The greatest positive change occurred in the year, 2011-12 and the greatest negative change occurred in the year, 2018-19. In zone one, the total sugarcane cropping areas increased, compared to the sugarcane cropping areas in zone two, this is because zone one has more area under irrigation. Coffee Coffee is a dominant crop in zone three, because it is situated in the Western Ghats. The area’s growing coffee is increased in zones two and zone three. In zone two, the greatest positive changes were recorded in the year 2018-19. Total areas growing coffee crops gradually increased from 2009-10 to 2018-19 in zones two and three. Mainly because it is one of the income oriented plantation crop the formers in these areas gradually encroached forest land for cultivation of coffee crops. Tobacco The total area growing tobacco crops increased in all three zones. In zone one, the highest positive change can be observed in the year, 2018-19 i.e., 2739.74 hectares. In zone three, tobacco cultivation began and continued after 2012-13. This crop was concentrated on, only in Somvarpet taluk. AREA INDICES OF SELECTED CROPS (from 2008-09 to 2018-19) The year 2008-09 is considered as the base year for comparing and reviewing areas for the selected crops during the periods under study. Paddy The index number, of the paddy areas, was below 100 percent during the period under study. Table 5.5 shows that the indices of paddy areas have decreased up to 28.17 percent in zone one, in the year 2008-09. Below 50 percent indices were observed in the years 2010-11 and 2011-12. In zone two, the area’s growing paddy, decreased by 44.43 percent in 2009-10, Copyright © 2021, Scholarly Research Journal for Humanity Science & English Language

CONCLUSION: There has been remarkable variation in areas of different crops. All cropped areas indicate increases and decreases in their areas from 2008-09 to 2018-19. In the zone one maize, sugarcane and tobacco crops recorded positive increase compare to base year. Paddy crop recorded native decreased in the all zones. In zone two jower, coffee and tobacco crops recorded positive increase and in the zone three coffee and tobacco crops recorded positive changes in the study period. While compare the all zones the highest positive change can observed in the crops of coffee, maize and tobacco and highest negative change is recorded in the crop of paddy and ragi. This changes is indicate the famers are gradually decreases to cultivate the traditional crops they are practices to cultivate the commercial crops, because from the traditional crops they will get less income compare to the commercial crops.
