Rice production in Ghana produced more N2O than CO2 -- African Crop Science Vol.21 No.2
Today we are featuring African Crop Science vol.21 no.2, the second post in a series of posts we are doing on African Crop Science.
This issue features articles such as "Greenhouse Gaseous Emission and Energy Analysis in Rice Production Systems in Ghana" by Eshun et al. Because Africa is trying to increase its agricultural productivity, the need to examine what greenhouse gases are emitted and its energy-efficiency has grown. Little research has been done on the environmental impacts of rice production and how the management and system of rice production could be improved to be more environmentally friendly. For this study, rice (Oryza sativa) production in Ghana is analyzed. Greenhouse gas emissions and energy impacts were measured. The results indicated that rice production in Ghana produced more N2O than the other two main greenhouse gases, followed by CO2. During rice production, approximately 477 kg of CO2-equivalents of greenhouse gases were emitted. The amount of greenhouse gases measured during different stages of production had varied emitted amounts, depending on the stage that was being recorded. In this study, fertilizer application produced 72% of greenhouse gases, while transportation to mills produced 10% of greenhouse gases.
This issue also includes "Markets and Rural Services As Determinants of Improved Seeds Usage by Crop Farmers in Osun State, Nigeria" by Adejobi & Kassali. This study aims to uncover how markets and rural services affect the use of better seeds by farmers. The study was conducted in Osun State in Nigeria, where 270 farming households were surveyed using the multistage sampling technique. The results indicated that accessibility to market information and socio-economic characteristics of farmers were among factors influencing the use of improved seeds.
