Many yield-enhancing and improved soybean varieties (ISVs) have been bred and distributed in Ghana. However, little is known about the predictors of ISVs’ adoption and the magnitude of their effects on productivity and household welfare. This paper explores the welfare effects of adopting ISVs using data collected from 330 soybean farmers in Northern and Savannah regions of Ghana. The results indicated that about 47% of the sampled farming households have adopted the ISVs. Adoption of ISVs was influenced by factors such as farm size, engagement in non-farm economic activities, membership of farmer group and household asset. Using both Instrumental Variable two-stage least square (IV-2sls) and Generalized Method of Moments (GMM) estimators to correct for both observed and unobserved differences in household characteristics, the adoption of ISVs led to significant gains in productivity/yields and food consumption expenditure per capita (welfare indicators). Overall, the findings suggest that ISVs need to be scaled up in order to have</em> <em>a strong influence on the welfare of smallholder farmers in Ghana.</em></p> Gideon Danso-Abbeam ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 2022-12-14 2022-12-14 8 2 160 172 10.47881/346.967x COVID-19, Agriculture and Food Security in Ghana; The Way Forward https://gjstd.org/index.php/GJSTD/article/view/342 <p><em>Food production, its availability, and accessibility will continue to be key contributors to human existence. The world was hit by the COVID-19 pandemic in the year 2020 and its effect trickled into reduced production of goods and services in many industries across the globe. Understanding the effects of the pandemic in Ghana necessitated the write-up of this paper. The study took the form of a desk review where current studies across the globe on the effect of the pandemic on agriculture and food security were reviewed, after which it was supported by data from self-placed questionnaire administration. Across the globe, agricultural production experienced a reduction that phased into food insecurity. This was not limited only to the extremely affected countries, but also, in countries where COVID-19 infections were low. One key limiting factor that spiked the challenge in the agricultural sector was a reduction in the availability of labour for production. In many leading food-producing countries, the challenge became acute when perishable food crops began to get damaged. In Ghana, the virus similarly led to restrictions in movements in and between epicenters. It was reported by the Ghana Statistical Service that, 77.4% of Ghanaians were negatively affected by the increased prices in food sold in the country. Without immediate and effective management as well as policy interventions from the Ghanaian government, it is highly possible for most farmers and agricultural businesses to completely collapse. This communication is to highlight some ongoing and disturbing effects of the pandemic to policymakers as well as individual and governmental strategies that have been put in place to curb adverse effects on food production. This will help enhance Ghanaians’ standards of living amidst economic challenges<strong>. </strong></em></p> John Tennyson Afele Emmanuel Gyan Ansah Eunice Nimo Sydney Stanley Blankson David Ofoe Gorleku Esther Odi Tieku Cindy Yaa Gyeniaw Maxwell Osei Hene Raphael Babatunde ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 2022-12-14 2022-12-14 8 2 147 159 10.47881/342.967x Preliminary study on the Effect of NPK (15-15-15) fertilizer and plastic mulch on growth and yield of three chili cultivars grown in field and pot conditions https://gjstd.org/index.php/GJSTD/article/view/380 <p><em>The study was conducted to investigate the effect of Black Plastic Mulch (BPM) and different rates of NPK (15:15:15) fertilizer on the growth and yield of three chili cultivars under field and protected cultivation.&nbsp; Two levels of mulch (BPM and no mulch), three levels of NPK (0, 200 and 300 kg/ha), and three cultivars “Demond F1” (DF1), “Legon 18” (L18), and “Shito Adope”, (SA) were used.&nbsp; Split application of half of each of the 200 and 300 kg/ha rates were applied two and four weeks after transplanting.&nbsp; Vegetative growth indices, soil moisture, and soil temperature were measured at 2, 4, 6, 8, and 10 weeks after transplanting. The yield was calculated using </em><em>AVRDC (1990)</em><em> formula for chili pepper. The study revealed an increase in soil temperature and moisture under BPM for both studies. Also, 200 kg/ha NPK and BPM led to an increase in vegetative growth and yield for DF1 and SA. However, 300 kg/ha NPK decreased vegetative growth. In addition, there was no significant influence of BPM on the number of fruits harvested. &nbsp;However, for the pot study, BPM led to an increase in the number of fruits for “Legon 18” as compared to the other cultivars. The study, therefore, concludes that 200 kg/ha NPK was the best when cultivating DF1 and SA, for chili growth and development in the savannah ecological zone</em><em>. </em></p> H. Musah Nimatu G.
