Abstract
This study was conducted on the experimental site of the Faculty of Agriculture of Abdou Moumouni University of Niamey. Objective of the work is to study the culture of species Cajanus cajan while determining its applicability to the Sahel goat. Germination test was carried out in petri dishes. Experimental set-up consists of 360 pockets distributed in three blocks each containing four plots of which three plots received urea, three received the NPK, three others received the manure and in the end three were kept as controls. Time between the establishment of grain culture in petri dishes and first appearance of radicle is one day and the staggering of germination is four days. The emergence of seedlings was observed 7 days after sowing in pockets. The seeds have a germination rate of 67.14%. At the first harvest, biomass production is 78.84; 89.42 and 79.87kg / ha respectively for plants treated with urea, NPK 15-15-15 and for plants treated with manure. Production of control plants is 50.45 kg / ha. Species Cajanus cajan has a higher appetence rate (80%) compared to species Leuceuna lecocephala and Gliricidia sepium which have respectively 66.66 and 46.66%.
Highlights
Pastoral areas represent more than 38% of the territory of Sahelian countries such as Mali, Mauritania, Niger, Senegal, Chad and Burkina Faso (Bernard, 2013)
The species Cajanus cajan commonly known as pigeon pea (Jonhson and Raymond, 1964, quoted by Chrysostome et al, 1998), is one of the most used both in the intertropical zone and in West Africa
Quenum et al (2016) recorded that germination rates are ranging from 77.5% to 85% on various varieties of pigeon pea, despite traditional conditions of storage and conservation of seeds at the producers
Summary
Pastoral areas represent more than 38% of the territory of Sahelian countries such as Mali, Mauritania, Niger, Senegal, Chad and Burkina Faso (Bernard, 2013). The possibilities of development of forage crops and improvement of pastoral production are enormous but remain dependent on certain determinants such as seed production, management and land development, especially pastoral areas. Niger is facing a long dry period, which means that animal production, especially food, is dependent on natural resources. They cannot meet the needs of animals. If the pigeon pea (Cajanus cajan) is very popular in West Africa by pastoralists for its tolerance to drought, its contribution to soil fertilization (Siambi et al, 1992), thanks to its richness in Nutrients, its adaptability to climatic conditions, its ability to regenerate soils and its multiple uses in humans and animals (Grâce et al, 2009), it is important to deepen its potential in terms of available forage.
