2.1 Short description of the Technology

Definition of the Technology:

The improved cowpea variety (IT90k372-1-2) has a short cycle, multiple resistance and is adapted to the tropical agro-ecological zone.

2.2 Detailed description of the Technology

Description:

As in all of Niger, the department of Mayahi in the southern central part of the country is characterized by a harsh natural environment with low precipitation, which is variable in space and time, and high temperatures, with a tendency to increase even more due to the effects of climate change, increasing the aridity of the region. With 3,1%, the population is growth is very high. The pressure on the natural resources has also strongly increased, and the chronic food insecurity regularly affects the majority of the population.
Millet and cowpea are the main agricultural products of the region, but due to the demographic pressure, the arable land is practically entirely in use. Consequently, food security can only be achieved through an increased production.

The cowpea variety IT90K-372-1-2 is of an inbred line nature and was developed in 1990 by the International Institute of Tropical Agriculture (IIAT) based in Ibadan in Nigeria. It has a growth cycle of 60 to 70 days with a semi-erect bearing and a spread bloom. The potential yield of IT90K-372-1-2 is 1.2 to 1.5 tonnes per ha. The grains are white-coloured with a red-coloured eye. This variety is resistant to drought (isohyet 300-600 mm), tolerant to aphids, but sensitive to striga, thrips and beetles. It grows as well on fertile land as on degraded land. Its growth cycle is well adapted to the rainfall, especially in regions with a chronic rainfall deficit. Through its capacity for symbiotic nitrogen fixation, integrating cowpea in the crop rotation enables to fulfill the requirements for nitrogen fertiliser of the subsequent crops (Bationo et al., 1990). This variety was registered in the catalog of improved varieties of Niger in 2010 by the National Agronomic Research Institute of Niger (INRAN).
The recommended period for seeding are the first fifteen days in the month of July. The field should be well ploughed to promote the root development. In the zones with more fragile zones prone to erosion, it is recommended to adopt minimum tillage or no-tillage. Three grains must be sown in each pocket, and thinned out to two plants per stem two weeks after seeding. The latter is done in a pit of 2,5 to 5 cm depth in the soil ridges, or in the surface, depending on the type of soil preparation. Approximately 20 kg/ha of grains of IT90K-372-1-2 are used with a spacing of 75 cm x 20 cm. This variety does not require so much nitrogen fertiliser because, like any variety of cowpea, it fixes nitrogen from the atmosphere by the nodules contained between its roots. Nevertheless it is essential to apply it in small quantities (around 15 kg/ha of nitrogen) when starting on poor soils. A nitrogen excess leads to a low grain production and a strong vegetative growth. Around 30 kg of P/ha is recommended in the form of Supa for the production of cowpea in order to support the crop to nodulate to fix atmospheric nitrogen. Weeding with a hoe is the most frequently used method by the farmers; it is done for a first time two weeks after seeding and a second time 4-5 weeks after seeding to keep the field clean of weed.
Cowpea contributes for a substantial part to meeting the food requirements of the population in tropical countries (Bressani 1997). The variety IT90K372-1-2 is appreciated by the producers because of the size of its grains (large), the colour of the grains (white) and the taste.
