“…This implies that time trend variable accurately explained the variation in the area of cowpea under cultivation, output and yield per hectare, respectively. This result is validated by the findings of Abid et al (2018) and Nmadu et al (2015).…”

The study examined the trends over the years of cowpea cropped area, output and yield per hectare. Time series data of cowpea area and production in Nigeria (2006 - 2018) obtained from the Central Bank of Nigeria annual bulletins were used for the study. Data were analyzed using three (3) trend models; linear, quadratic and exponential growth models which were fitted and the exponential growth models were selected on econometric basis in the analysis. The result of the exponential model showed positive compound growth trends in area (0.031) and output (0.039), but with negative growth trend of -0.008 for the yield/ha analysis. The doubling times for the growth rates were estimated at 17 and 14 years to double the growth rates in cowpea cropped area and output. Result of the growth pattern disclosed that there was deceleration in the growth of cowpea cropped area, output and yield/ha for the period under consideration. It was concluded that that the marginal compound growth rates in cowpea area, output and yield/ha resulted in actual retardation in cowpea production. The study recommended that the trend results can be reversed by land improvement mechanisms that will increase the yield/ha, and the incorporation best practices like Purdue Improved Cowpea Storage (PICS) to achieve the dual objectives of increased production and market successes.

“…Over the previous three decades, there has been an upward trend in potato production (Sreepriya, Sidhu and Kumar, 2017). The predicted values of both area and production of potato crops illustrate the growing trend (Abid et al, 2018). This study also shows the increasing trend of the area of cultivation and production.…”

Although Bangladesh is known as a rice-eating country, enormous amounts of potatoes are produced and consumed each year. Potato has gradually acquired popularity in Bangladesh. Potato is grown as a food crop and a vegetable by both the rich and the poor. This study attempts to measure the trend, growth, and instability of potato production. Besides, here is an attempt to forecast the potato production of the coming years. This secondary data was gathered from the website https://www.potatopro.com/bangladesh/potato-statistics. Here, different statistical tools including t-test, correlation, simple linear regression, semi-log growth model, ARIMA (0,2,1) model, simple exponential smoothing, and Holts Damped trend method were used. Potato production is increasing in Bangladesh. It seems that the production of potatoes will continue to increase in the coming years. The growth rates of potato production in the whole period, period-1 and period-2 are 6.7, 2.7, and 9.3 respectively and CV's around the trend line are 40.28, 7.43, and 10.46 respectively. Therefore, potato production in Bangladesh is showing an increasing trend. It seems that the production of potatoes will continue to increase in the coming years. Potato production in Bangladesh is increasing and it is unstable. The government and numerous non-governmental organizations (NGOs) must work together to increase potato production.

“…Nearly 65% of barley throughout the world is employed for animal feed formulations, 33% for malting application while only 2% is processed as a human diet (Sullivan et al., 2013). The main reason for less production is improper crop safety and its application as fodder (Naheed et al., 2015). However, the crop shows great adaptability and tolerance against the unfavorable environment; therefore, it is successfully grown even on high altitudes of the Himalayas and in the Arctic Circle region (Zhu, 2017).…”

Barley belongs to the Poaceae family, grown and consumed in Africa, Asia, semi-arid tropics, and also grown in Europe, America, and Australia (Erkan et al., 2006). The crop possesses health-promoting nutritional and functional properties (Cook, 2013;Idehen et al., 2017). The main components of barley are carbohydrates with low fat, protein, minerals, vitamins especially vitamin E, dietary fiber, and antioxidants predominantly polyphenols (Das et al., 2016).The nutritional constituents of barley consist of health-promoting
