Crop evapotranspiration (ETc) is the basis for calculation plant water needs. Various methods might be used for determining ETc such as the soil water balance that has the following components: water storage variation (h), precipitation (P), irrigation (I), deep percolation (DP), evapotranspiration (ETc) and run off (R). The way these components are measured affects the accuracy of the method. The objective of work was to determine banana evapotranspiration by using soil water balance method with data collected by a TDR equipment at different distances from the banana pseudostem. Soil water content was monitored at various horizontal distances (R) from a banana pseudostem and soil depths(Z) in a 0.20 m x 0.20 m grid of a vertical plane between two pseudostems along plant row. Results showed that evapotranspiration and deep percolation are not uniform around a banana pseudostem and varied according to water and root distribution in the soil profile. The larger values of deep percolation and smaller values of evapotranspiration occured at zones of the soil of smaller percentage of total root length and vice versa |

Ecological intensification, or the improvement of crop yield through enhancement of biodiversity, may be a sustainable pathway toward greater food supplies. Such sustainable increases may be especially important for the 2 billion people reliant on small farms, many of which are undernourished, yet we know little about the efficacy of this approach. Using a coordinated protocol across regions and crops, we quantify to what degree enhancing pollinator density and richness can improve yields on 344 fields from 33 pollinator-dependent crop systems in small and large farms from Africa, Asia, and Latin America. For fields less than 2 hectares, we found that yield gaps could be closed by a median of 24% through higher flower-visitor density. For larger fields, such benefits only occurred at high flower-visitor richness. Worldwide, our study demonstrates that ecological intensification can create synchronous biodiversity and yield outcomes. |
