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.
Growth and instability analysis in Indian agriculture
International journal of Multidisciplinary Research and Development, 2018
Agricultural growth and instability has remained subject of intense debate in the agricultural economics literature in India. Instability is a very essential characteristic of agriculture. Since agriculture is dependent on weather conditions, the area, production and yield of the crops are subject to significant variations over time. This study aims at studying the growth and instability in the major crops of India. Cuddy Della Valle Index and Coppock's instability index has been calculated for all the crops. The entire study period is divided into three sub-periods-17. Several fluctuations in the growth pattern of area, production and productivity of the crops were observed in the study. Also, different pattern of instability were observed in the area, production and productivity of the crops over the period.

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.

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.
Trend and Instability in the Growth of Major Agricultural Crops in India: 1950-2003
The output of major crops grew by over 3½ % pa before the Green Revolution, and 3% pa after 1981. The cropping pattern did not contribute to this deceleration. However, changes in the cropping pattern in favour of high yielding crops seem to have contributed 1/5th of the trend growth of major crops. The remaining 80% of the trend in output may be attributed to changes in area and adjusted yield. Expansion in area sown under major crops accounted for 1/3rd of the annual trend of adjusted output before the green Revolution. After 1981, this fell to about 1/4th of the annual trend in adjusted output of major crops. Before the Green Revolution the trend in area was almost 1% pa, falling to 0.55% pa after 1981. Most of the deceleration in adjusted output (can be attributed to this slowdown in the growth of area under major crops. The yield of major crops, after freezing the cropping pattern, appears to trend at an average 1.9% pa. The green revolution has added nothing to this trend. The...
