Effect of NPK application dates on agronomic parameters of two Bambara groundnut varieties cultivated on ferric Lixisol in northern Sudanian Sector of Burkina Faso

Bambara groundnut is a neglected legume crop that contributes to improve global food and face insecurity. In Burkina Faso, research on cropping system were essentially focused mounding times. Less attention has been paid the application of fertilizers. Experiments was carried out site Tenkodogo University Centre (11°48’37’’N, 0°22’19’’W), Faso study response two varieties different NPK periods. The experiments consisted factorial combination factors, including (KVS 235 KVS 246) dates (At basal, 7, 15 21 days after sowing) in completely randomised blocks with three replications. Characters collected, plant height spread, total biomass at flowering, stalks weight, yield-components yield. results indicated most characters not varied significantly for both whatever period except weight (P = 0.013). interactions between had significant effects only flowering 0.048). addition, pod length effect 0.032) varieties. mentioned above implies fertilizer have influenced characteristics differently, depending bringing. basal lead best performance regarding seed dimension 100-seeds general, KVS235 outperformed than 246.
