ABSTRACT

For sustainable agriculture, efficient use of energy is of utmost importance. This study was conducted for a period of 3 years in Central Anatolia region of Turkey to find out how the energy balance was affected under different planting methods. Split plot design with four replications was used in the study. While the main plots included planting methods, the subplots included the varieties. Energy use efficiency, energy productivity, specific energy and net energy were investigated. According to the results obtained, energy inputs were found to be lower in bed planting (26.38 GJ ha⁻¹), when compared with conventional flat planting (26.51 GJ ha⁻¹). Energy use efficiency was found to be higher in conventional flat planting (7.15) when compared with bed planting (5.39). While grain yield (GY), biomass yield (BY) and number of spikes m² (NS) were found to be higher with conventional flat planting, harvest index (HI) and thousand kernel weight (TKW) were found to be higher with bed planting. It was concluded that the variety chosen was extremely important in the success of bed planting method.

摘要

对于可持续农业，能源的有效利用至关重要。这项研究在土耳其安纳托利亚中部地区进行了为期 3 年的时间，以了解不同种植方法对能量平衡的影响。研究中使用了四次重复的裂区设计。主地块包括种植方法，子地块包括品种。研究了能源利用效率、能源生产率、比能和净能。根据获得的结果，与传统平地种植（26.51 GJ ha ^-1）相比，床种植（26.38 GJ ha ^-1）的能量输入较低）。与床铺种植 (5.39) 相比，传统平地种植 (7.15) 的能源利用效率更高。虽然发现传统平地种植的谷物产量 (GY)、生物量产量 (BY) 和穗数 m ² (NS) 更高，但发现收获指数 (HI) 和千粒重 (TKW) 更高种植。得出的结论是，所选择的品种对于床栽法的成功极为重要。
