The present study was aimed to analyse the growth and instability in area, production and productivity of different crops in Bagalkot and Vijayapura districts and structural changes of agriculture and horticulture crops. The secondary data were collected and analysed using compound growth, instability analysis and Marcov chain. The result of showed that highest CAGR in case of area and production of Bengal gram in Bagalkot was 12.97 per cent and 12.09 per cent, respectively where as in Vijayapura highest growth rate in production was 18.78 per cent for Maize may be due to more suitable agroclimatic conditions. In case of Bagalkot district, onion could retain maximum area i.e, 74 per cent but in Vijayapura district about 82.86 per cent of area was retained by sunflower. Soyabean had lost all its area to other crops may be due to non-availability of competitive price in the market.

The present study has made an attempt to examine the instability in the area, production and productivity of barley crop in India and Haryana during three phases i.e. pre-green revolution, green revolution and post green revolution period. The study is based on secondary data and used three analytical methods. The results showed that in case of area, the instability is more in the post-green revolution than pre-green revolution period as the focus of the green revolution was mainly on other crops like rice and wheat. In case of production, instability showed a decreasing trend from pre-to post-green revolution period due to the adoption of new technology and good quality seeds during the green revolution. A same decreasing trend was observed in yield instability also. In case of growth pattern, the area in Haryana and India both shows a negative growth trend in the pre-green revolution. In case of production, in Haryana, negative growth trends were observed in the green revolution period but in the post-green revolution, it was positive growth; while in India as a whole growth rate was negative. In case of yield, the growth rate was positive in both Haryana and India.

Growth and instability in the area, production, and productivity of total horticultural crops have always been the subject of intense debate. In this study, trends in the growth and instability of horticultural crops in India for the last 15 years, from 2003-04 to 2017-18, have been examined. In agriculture, instability is a very aspect that indicates the variation in data. Indian agriculture is primarily dependent on the monsoon. If the monsoon fails, Indian agriculture faces significant loss and variations, especially in production over time. Cuddy Della Valle Index has been used for estimating instability in the area, production, and productivity of horticultural crops. Several fluctuations in the growth pattern and instability of the area, production, and productivity of the crops in northeastern states over the period were observed in the study. Production of horticulture crops increased in the northeastern state due to an increase in area.
Trend and Growth Rate Estimation of Principal Crops in Karnataka State in India
International Journal of Plant and Soil Science, 2022
The study undertaken to analyse the growth rate performance of area, production, productivity of selected crops in Karnataka from year 1997 to 2019. At state level, it was found that, the productivity of cereals showed positive growth with 1.22 percent. The area under maize increased by 5.30 percent by displacing Jowar, Bajra, minor millets. The rice and maize became stable crops in cultivation due its assured support prices and procurement from government. The production of pulses increased by 4.17 percent. The area under oil seeds showed negative trend with-5.87 percent which may be due to its high cost of production and unremunerative prices where as the commercial crops has recorded positive growth rates of production (2.69 percent) and productivity (2.43 percent) despite of its 0.24 percent area growth. The farmers prioritised sugarcane, cotton because of less labour requirements, good market prices. The Technology mission on oilseeds and Pulses in post 1990's could be reason for increased production and productivity of pulses.

The study has examined productivity instability of major crops for 20 years by considering first period as 1998-99 to 2008-09 and second period as 2009-10 to 2018-19 at the district level in Karnataka state. Instability categories were grouped as low < 15%, medium 15-30% ,High >30%. A low value index indicates the high stability in crop productivity. Through Cudde Della Valle index it was observed that, instability has been low and declined over the time in Rice, Maize, Sugarcane while medium instability noticed in Ragi, and cotton .The trend of instability is high in Arhar, Gram, Groundnut and Jowar. Instability in Pulses and oil seeds is high because area under these crops have been shifted towards Rice, maize which are giving high remunerative prices and assured profit.
Analysis of growth rate and yield instability of major crops of the northern dry zone of Karnataka
2023
Karnataka state has the second largest area under rain-fed agriculture i.e., 7.01 m.ha after Rajasthan. It is highly vulnerable to changing climate and its extreme climatic conditions threatening the food security of state. The Northern Dry Zone (NDZ) of Karnataka was purposively selected for the study as it was drought vulnerable and was affected by changing climate. The study was undertaken to examine the growth rate in area, production, and productivity of major crops of NDZ i.e., four districts namely Bagalakote, Ballari, Koppal and Vijayapura districts over the period of 22 years (1997-2019). Maize and chickpea crops, Compund Annual Growth Rate (CAGR) was found to be significantly increasing in area and production whereas, productivity was found to be increasing significantly incase of rice and sorghum crops. Farmers were practiced of growing pulses as they were short-duration crops and drought tolerant by nature. Cropping intensity (CI) was increasing over the years in all dry districts to avoid crop failures and risks. Sesamum was found unsuitable crop to be grown in the Northern Dry Zone. Based on water availability, rice can be grown in the zone as the yield instability index is low.
Instability in Production and Productivity of Horticultural Crops in Assam
Background: Horticultural crops in Assam play a significant role in contributing towards overall agricultural production of the state. During last two decades, the production of horticultural crops in the state has increased steadily but only a few studies were found on horticultural sector particularly. So, the present study examines the growth and instability in production, productivity and area of horticultural crops in Assam. It also analyzed different factors contributing towards production of horticultural crops in the state and nation. Methods: The study is totally based on the secondary sources of data. Various statistical techniques like exponential growth rate, Karl Pearson correlation coefficient etc., are used to examine growth and instability. However, instability is estimated with the help of Cuddy Della Valle index. Result: The study showed that production and productivity of horticultural crops increased over the period, but, there is instability in production, productivity and area at both state and national level. On the other hand, there is a high positive correlation found between area and production of horticultural crops. Regarding the contribution towards production of horticulture in Assam and in India, area and productivity of horticulture have found high impact respectively.
Changing Pattern of Area, Production and Productivity of Principal Crops in Haryana, India
International Journal of Current Microbiology and Applied Sciences, 2017
The study was based on secondary data collected from various issues of Statistical Abstracts of Haryana and other published and unpublished sources. The results revealed that with the passage of time, there has been a substantial change in the cropping pattern in the state. In overall study period (1993-2013) the area, production and productivity of food grains has shown increasing trend with a compound annual growth rate of 0.56, 2.56 and 1.93 per cent per annum while for pulses all these values were in negative. Average area has increased only in case of rice, wheat and barley while the area under other crops like jowar, bajra, maize, cotton, sugarcane, etc. declined during the study period. The cropping pattern has skewed towards rice-wheat cultivation. The decline in the growth of area for pearlmillet and sugarcane is due to shift of area towards paddy while decrease in area of gram is due to shift of area towards wheat.

Growth Performance of Major Crop Groups in Odisha Agriculture: A Spatiotemporal Analysis
Agricultural Economics Research Review, 2016
This study has analysed the pattern in growth of area, production and productivity of major crop groups across the physiographic zones in the state of Odisha for the period 1993-94 to 2010-11. It has observed an unstable and unsustainable growth in area, production and productivity over the years in the state as well as in all physiographic zones. The relatively high growth rate of foodgrains production in Odisha has been achieved mainly through area effect. Although, contribution of technology towards sustainable output growth has been recognized, growth in the yield rate is slow. This sluggish growth in area, production and yield of all crop groups in the state is because of slow expansion of irrigation network, low level of fertilizer consumption, slow rate of technology adoption, and low level of infrastructural development. The slowdown in the process of cropping pattern change indicates the failure of most government efforts to diversify agriculture in the state. It is time to reform this sector and accord importance to food safety issues to meet the growing demand for quality food through stable and sustainable growth in agriculture and replacing subsidies with investments and infrastructural development.
Growth and Diversification of Horticulture Crops in Karnataka: An Inter-District Analysis
SAGE Open, 2014
With the growth of technology, modernization, and changes in food habits, agricultural cropping pattern of the country has undergone a major shift in the recent past, moving away from the cereal to non-cereal crops cultivation, especially toward the horticulture crops. Horticulture has been one of the fastest growing sectors within the larger agriculture activities in India, and the State of Karnataka is at the forefront in this context. With the help of secondary data and by employing Simpson's Diversification Index, crop diversification toward horticulture across the districts of Karnataka was explored. Using regression growth trends, the districts have been categorized as high, medium, low, and negative growth trend of horticulture crop area, and the districts have been further regrouped according to their agro-climatic zones. The study found that the districts of Gulbarga, Raichur, Bijapur, Bidar, Koppal, Bagalkot, and Bellary showed a complete diversification toward horticulture crops, whereas the districts of Kolar, Udupi, and Dakshina Kannada were found to be diversified the least. The study also explored that the districts having complete diversification toward horticulture sector were found to have devoted a lesser share of their cultivable area under horticulture crops. Also, most of the highly diversified districts have come under the dry agro-climatic zones and experienced a high growth rate of horticulture crops cultivation from triennium ending (TE) 2002-2003 to TE 2009-2010. However, the lesser diversified districts have got lesser growth rate of area under the horticulture crops, but devoted relatively a higher share of area under the crops.
