What is it about?
Water and phosphate deficits are among the main limiting factors which decrease Bambara groundnut yield. This study aimed to evaluate the effect of water deficit and phosphate fertilizer on the growth and biochemical composition of Bambara groundnut.

Why is it important?
The results show that phosphate fertilizer significantly improved growth and biochemical composition under water deficit or none. The leaves dry weight increased from 22.6 % from 0 to 100 mg P2O5 at 30% FC. At 90% FC, the doses 20, 40, 60, 100 mg of P2O5 increased sugar content by 39, 50, 65, and 47%, respectively, compared to 0 mg P2O5. Proline content at 30% FC was twice that of 90% FC. Increased accumulation of sugars, proline, and amino acids in leaves was recorded at the severe level of water deficit. Phosphate fertilizer mitigated the adverse effect of water deficit on the growth and biochemical composition of BG.
Perspectives
Writing this article was a great pleasure as it was co-authored by co-authors with whom I have had long-standing collaborations. This article emphasizes that adequate P supply is recommended to help plants escape, avoid or tolerate water deficit.
