Abstract To move toward the principles of ecological agriculture in the direction investigating environmental and nutritional effects on yield and nitrogen efficiency of chickpea (Cicer arietinum L.), a field experiment was conducted on the experimental farm of Gonbad Kavous University, Iran; during the growing seasons of 2016 and 2017. The experimental layout was based on a factorial randomized complete block design with three replications and three factors. Three factors were Nitrogen (N) at four rates (0, 20, 40 and 60 kg N ha−1), two planting date (early January and early February) and two Mesorhizobium biological fertilizer levels (inoculation with Mesorhizobium and no-inoculation). Maximum seed yield, N agronomic efficiency, N utilization efficiency and N use efficiency were obtained from early January. The highest protein percent in seeds and N percent in straw were obtained from early February. Although, protein percent of seed, N percent of residues and seed yield increased with N rate, the N agronomic efficiency and N use efficiency decreased. The inoculation with Mesorhizobium had positive effects on yield and N use efficiency but had negative effect on N agronomic efficiency. The effect of biofertilizer levels was different at each planting date for seed protein percent in 2016.

伊朗温暖和半干旱气候下环境和营养对鹰嘴豆(Cicer arietinum L.)产量和氮效率的影响

摘要 为了研究环境和营养对鹰嘴豆(Cicer arietinum L.)产量和氮肥效率的影响,从生态农业的原则出发,在伊朗贡巴德卡沃斯大学的实验农场进行了田间试验;在 2016 年和 2017 年的生长季节。实验布局基于因子随机完整区组设计,具有三个重复和三个因子。三个因素是四种比率的氮 (N)(0、20、40 和 60 kg N ha-1)、两个种植日期(1 月初和 2 月初)和两个中生根瘤菌生物肥料水平(接种中生根瘤菌和不接种) . 从 1 月初开始获得最大种子产量、氮农艺效率、氮利用效率和氮利用效率。从 2 月初开始获得种子中最高的蛋白质百分比和秸秆中的 N 百分比。尽管随着施氮量的增加,种子蛋白质含量、残留物氮含量和种子产量增加,但氮肥农艺效率和氮肥利用效率却下降。接种中生根瘤菌对产量和氮素利用效率有积极影响,但对氮素农艺效率有消极影响。生物肥料水平对 2016 年种子蛋白质百分比的影响在每个种植日期都不同。
