“…It is important because it can help researchers and policymakers to predict future growth. The compound growth rates of area, production, yield, and price of pulses were calculated by fitting an exponential function of the following type (equation 1), which was done for simplicity and was frequently employed even in the recent past [6][7]. Y = ae bt or lnY = lna + bt (1) Where, Y is the area/production/yield of minor pulses, 't' is the time in a year, and 'a' is the constant, e b -1 is the compound growth rate which is expressed in percentage.…”

Providing a balanced diet to ensure food and nutritional security is the primary worldwide challenge. Food production efficiency and sustainability must be enhanced to address hunger and malnutrition, while food quantity and quality must grow. Pulses are an important food for the people of Bangladesh. Besides major pulses, we have to look at minor pulses as well. On the other hand, growth and instability are the two crucial aspects of agriculture. Since agriculture depends on weather conditions, the crop area, production, and yield are subject to significant variations over time. This study examined growth and instability in the area, production and yield of minor pulses using secondary data for the past 40 years (1981-2020). The entire period was divided into four sub-periods: 1981-1990, 1991-2000, 2001-2010 & 2011-2020 for analysis through different statistical tools. A suitable exponential growth function was used to calculate growth rates, and the Cuddy-Della Valle Index (CDI) was created to examine instability. The investigation showed that over the time period, both the area and production of minor pulses significantly decreased. However, the yield growth rate was modest and fell short of the demand in our nation. The investigation also revealed that there was no stability in the area, production, or yield of minor pulses during the course of the study.

For simplicity and widely used even in the recent past (Rahman et al, 2011;Das and Mishra 2020;Chaudhary et al, 2016) the compound growth rates of area, production, yield, and price of black gram were worked out by fitting an exponential function of the following type:…”

Growth and instability of crops are two crucial aspects that significantly impact the agricultural sector and its contributions to enhancing agricultural resilience, food security, economic development, risk management, income volatility, and sustainable practices to meet increasing demands and challenges precipitated by erratic weather patterns. Black gram is one of the high-value pulses in Bangladesh and is essential for human nutrition and sustaining agricultural soil quality. This study presents the growth and instability in area, production, and yield of black gram along with the contributory factors affecting the growth and instability of black gram production in the context of Bangladesh’s agricultural landscape based on secondary data for the last 40 years (1981-2020). The entire period was divided into four sub-periods: 1981-90, 1991-2000, 2001-10 and 2011-20 for analysis through different statistical tools. Growth rates were calculated by fitting an exponential growth function, and instability was analyzed by generating the Cuddy-Della Valle index. The analysis presented highlights a significant decrease in the area of black gram cultivation and production, even though there has been a notable increase in black gram yields. However, this increase in yield is not sufficient to meet the overall demand for black gram in the country. The study also points out that the growth rate of yield is low compared to the increase in demand. Throughout the study period, the contribution of the area was -3.29%, while the yield contribution was 142.25% in the average growth of black gram production at the national level. The analysis underscores the lack of stability in black gram cultivation, production, and yield during this period. Notably, there were instabilities of 4.37%, 4.89%, and -25.7% in the area, production, and productivity of black gram at the national level, respectively. Hence, researchers, policymakers, and farmers must prioritize advancing technology to boost black gram production. This enhancement holds the promise of improving food security in Bangladesh. Encouragingly, there are signs that the government has recently implemented incentives to support the cultivation of black gram. Bangladesh J. Agri. 2023, 48(2): 30-38

“…The most common tool used for calculating the growth rate is the compound annual growth rate and this study follows the method adopted by Das and Mishra [7]. This method analyses the trend in pesticide consumption and the final result is expressed in percentage per annum.…”

Aims: The main aim of this study is to examine the growth rate of consumption of pesticides in India and Tamil Nadu. Place and Duration of Study: The study was carried out using the time series data on pesticide consumption collected from secondary sources from 1990 to 2020 for India and for Tamil Nadu, the data were collected from 2011 to 2021. Methodology: The compound annual growth rate is used to calculate the growth rate of consumption of pesticides. The data is segmented for every 10 years and decadal growth rate was also examined. Results: The overall compound annual growth rate of pesticide consumption is negative(-0.44 per cent) and the decadal average was found to be -5.27%, -0.73% and 1.81% for the decades 1990-2000, 2001-2010 and 2011-2020 respectively for India. The growth rate for different types of pesticides was found to be declining (-2.26 per cent) for insecticides, however it is increasing for fungicides (2.65 per cent) and herbicides (0.99 per cent). CAGR indicates that there is no change in growth of pesticide consumption in Tamil Nadu. Conclusion: The trend in the pesticide use has been decreasing over the period and it shows that the total quantity of pesticides used in the country has been continuously decreasing which is a healthy sign for the environment. It may due to increase in the area of organic farming, practices like IPM and increase in the use of biopesticides.
