2.1 Short description of the Technology

Definition of the Technology:

Cover crops are crops grown on bare, fallow farmland or under a main crop to cover and conserve the soil by protecting it from exposure to the sun, wind, and direct impact of rain. It fixes nitrogen (if a legume), improves soil fertility, supplies livestock fodder, and helps manage both pests and weeds.

2.2 Detailed description of the Technology

Description:

Cover crops are planted to conserve the soil on bare, fallow farmland or under a main crop. They can be grown on their own or between rows of annual and perennial crops such as maize, coffee, and fruits. The main purposes of growing cover crops are to cover the soil with low-growing vegetation, protect the soil from exposure to sun and rain, suppress weeds, improve soil fertility, supply livestock feed, and manage insect pests. Cover crops may be nitrogen fixing (if legumes), and they make productive use of spaces between crop rows, as well as controlling wind and water erosion. They also have the potential to restore soil fertility and help in climate change adaptation, as well as sequestration of atmospheric carbon above and below soil surface. Furthermore, cover crops can be fed to livestock, helping to bridge periods of shortage of feed when grazing lands are not available – which is an increasing problem because of growing population pressure and expansion of croplands. Land users give huge credit for its role as a pesticide by deterring armyworm and stalk borer when used as a border, and stopping their advance into the maize crop.
Desmodium is an example of a leguminous cover crop, improving soil fertility via fixing atmospheric nitrogen, increasing infiltration and productive use of soil moisture, and catering for livestock via a “cut-and-carry” fodder system. Desmodium is planted between rows of maize crops as well as between grass hedgerows around the farm. For its establishment, access to desmodium seed is essential. Once established, it remains to serve as a permanent source of planting material. Nevertheless, there are some disadvantages of desmodium: seed collection is difficult, it may trap honey bees and it can compete with the crop for light and space if allowed to grow too tall. Thus, efficient management of desmodium is essential. Nevertheless, as part of an agro-ecological intervention, cover crops like desmodium deliver multiple benefits to resource-poor farmers and can be viewed as an investment in improving soil fertility as well as soil health. Overall, cover crops improve productivity, and help ensure yield stability and contribute to a healthier ecosystem.

Strengths/ advantages/ opportunities in the land user’s view
The technology improves soil fertility.

Supply protein-rich feed to the animals.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Cover crops provide multiple benefits to the family farmers such as the best uses of land between the rows of maize crops.
It smothers weeds and improves soil fertility and crop productivity which have a positive contribution to the livelihoods of family farmers.
Cover crops and the practice itself have a beneficial role in agroecology intervention and improvement of the ecosystem functioning.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view	How can they be overcome?
Fast growing and overwhelming the main crops (competition for space).	Applying intensive management such as cutting and feeding to the animals.
Feeding the animals with fresh harvest is not friendly to the livestock.	As it is a protein-rich fodder crop the harvest must be slightly dry and mixed with grass fodder that reduces the adverse effects of either bloating or diarrhea.

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
Difficulty to manage and harvesting desmodium seeds.	1. Intensify the management of desmodium and reduce harvesting inconvenience on main crop. 2. Replace desmodium with other farmer's friendly legume species such as Dolichos lablab...as cover crops.
Hooky nature of the seed that sticks to the clothes.	-Wear nylon wears/clothes that reduces the effects of hooky seeds. - Produce seeds on separate plots.
Quick growth and climbing traits that dominate the main crops.	- Apply intensive management and use the above-ground parts as fodder for the livestock by adopting cut-and-carry feeding system. Also, needs to keep the green parts under frequent management practices.
