Abstract

Millet is one of the most widely grown food crops in Niger. This study, conducted in the village of Digargo in Niger, aims to evaluate the combined effects of zai and the number of plants per pocket on millet growth and yield. A randomization experimental design with three (3) replicates was set up and where two (2) factors were studied. Factor (A) has two (2) levels A1 and A2 where millet is sown on zai treated soil and control soil respectively and factor (B) has 5 levels of number of plants per pocket. The best grain yields were obtained on soils treated with zaï with three (3) and four (4) plants per pocket, particularly A1B3 and A1B4, with respectively 2523 and 2187 kg/ha. On the other hand, treatments A1B3 and A1B4 are characterized by a good yield of ears, grains and a high thousand kernel weight. The zaï treatment helps to improve crop yields and can be recommended for agroecological management of soil fertility.
