| Abstract: |
| To explore the influence of water stress and clinoptilolite on peanut yield and water use, peanut pot experiments were carried out in a sliding canopy. The results showed that water stress significantly reduced the ground dry weight of peanut. Compared with W3, W1 and W2 decreased the ground dry weight of peanut by 24.00% and 10.60%, respectively. With the application of clinoptilolite, the ground dry weight of peanut increased significantly by 7.74%, and the interaction between water stress and clinoptilolite. Peanut yield was 38.05±4.82 g under moderate water stress, 7.69% lower than that of mild water stress, being the minimum decrease, while it was 42.37±1.04 g with clinoptilolite application and increased by 25.65% which was the maximum value. Water use efficiency of peanut was the highest (1.50±0.21 g·L-1) under moderate water stress (W2), while it was 1.68±0.09 g·L-1 after applying clinoptilolite which was the optimal treatment to get the beat water use efficiency. The moderate water stress and the application of clinoptilolite could achieve the goal of water saving and high yield of peanut. |
