Cowpea Response to Two Organic Fertilizers in the Nord Sudan Zone of Burkina Faso

Abstract

The Intensification of cowpea production is a priority because of its role in household income generation and its contribution to food security. To evaluate the effect of organic fertilizers on cowpea productivity, a dispersed block experiment design was set up in Saria in the semi-arid zone of Burkina Faso during the 2017 and 2018 cropping seasons. The combination of Biodeposit (Agro and Elixir) and Organova were used alone or in combination with mineral fertilizer. The results showed that during the two years, the highest cowpea grain yields were obtained with the Organova + the recommended mineral fertilizer and Biodeposit Agro + the recommended mineral fertilizer. The combination of organic fertilizers and recommended mineral fertilizer resulted in a 45% and 59% increase respectively with Organova and Biodeposit (Agro + Elixir). These two fertilizers then have the same effects on cowpea productivity. In the semi-arid zone where there is competition for organic resources, organic fertilizers can be used in combination with mineral fertilizer to improve cowpea productivity.

Effect of organic amendments on the growth, yield and nutrient status of cowpea (Vigna unguiculata (L.) Walp.)

“…The result is supported with the findings of Yadav et al (2019) and Sakpal et al (2021). Ouedraogo et al (2021) found increased grain and biomass yields of cow pea in combination with organic and recommended mineral fertilizer dose.…”

“…Replacing inorganic chemicals with organic one is effective in reducing environment pollution and producing safe food for human being (El-Sharawy et al, 2018). However, the increase in growth and yield of cowpea plant depends both on the boosting of soil fertility through the application of organic amendments and the use of fertilizers (Ouedraogo et al, 2021). There is little information available on the growth of cow pea plant in Bangladesh with the application of organic fertilizer.…”

Evaluation of the Effect of Stone Lines and Microdosing Adoption on Sorghum Yield and Income: A Case of Smallholder Farmers in Burkina Faso

“…Asfaw and Neka (2017), Kumar et al (2021), and Mondal et al (2018) demonstrated the soil and water conservation (SWC) structures significantly reduce soil erosion while improving crop yield. However, some studies have further investigated the benefits of optimizing fertility through microdosing on crop yields (Marenya et al, 2020;Ouedraogo et al, 2021;Timilsena et al, 2015;Traore et al, 2019). In addition, Kassie et al (2011), Manda et al (2016), and Zeeshan et al (2021) showed that fertilizer management significantly improves household income.…”
