Planting spacing is the systematic evaluation of the farm area or any growing surface for crop production. In order to study the effect of varying planting patterns in two garlic (Allium sativum L.) cultivars, an experiment was carried out as a factorial design based on randomised complete block design with three replications in the farm of Gonbad-e-Kavous University during 2016-2017. The factors consisted of seven planting spacing (12.5.12.5, 15.15, 17.5.17.5, 20.20, 22.5.22.5, 25.25 and 27.5.27.5 cm) and two cultivars (Tarom and Hamedan). The fresh bulb yield, bulb weight, clove weight, clove number of bulb, plant height, bulb diameter, bulb length, clove diameter, skin number and stem length were recorded. Results showed that there were significant differences between both planting spaces and cultivars in all variables assessed. The highest bulb yield (19,014 kg ha–¹) was recorded in Hamedan with the spacing 12.5.12.5 cm, while the lowest bulb yield (7572 kg ha–¹) was detected in Tarom with the spacing 27.5.27.5 cm. The highest number of cloves was produced by Hamedan under the 27.5.27.5 cm arrangement. In addition, upon the correlation analysis between variables, the bulb weight showed the highest effect on garlic yield that bulb weight was negatively correlated with bulb yield (r₌ –0.60**). Generally, Cultivar Hamedan had a higher yield and yield components than Tarom and the spacing 12.5.12.5 cm had a higher yield than the other spacing.

品种和种植间距对大蒜产量和产量构成的影响

种植间距是对农场面积或作物生产的任何生长表面的系统评估。为了研究不同种植模式对两种大蒜 (Allium sativum L.) 品种的影响，在 Gonbad-e-Kavous 大学农场进行了一项基于随机完全区组设计的因子设计试验，三个重复。 2016-2017 年。因子包括七个种植间距（12.5.12.5、15.15、17.5.17.5、20.20、22.5.22.5、25.25和27.5.27.5 cm）和两个栽培品种（Tarom和Hamedan）。记录鲜鳞茎产量、鳞茎重量、丁香重量、鳞茎丁香数、株高、鳞茎直径、鳞茎长度、丁香直径、皮数和茎长。结果表明，在评估的所有变量中，种植空间和栽培品种之间存在显着差异。最高的球茎产量 (19,014 kg ha–¹) 记录在哈马丹，间距 12.5.12.5 cm，而最低的球茎产量 (7572 kg ha–¹) 在 Tarom，间距 27.5.27.5 cm。在 27.5.27.5 厘米的排列下，哈马丹生产的丁香数量最多。此外，根据变量之间的相关性分析，鳞茎重量对大蒜产量的影响最大，鳞茎重量与鳞茎产量呈负相关（r₌ –0.60**）。一般而言，哈马丹品种的产量和产量构成比塔罗姆高，12.5.12.5 cm的行距比其他行距的产量高。在 27.5.27.5 厘米的排列下，哈马丹生产的丁香数量最多。此外，根据变量之间的相关性分析，鳞茎重量对大蒜产量的影响最大，鳞茎重量与鳞茎产量呈负相关（r₌ –0.60**）。一般而言，哈马丹品种的产量和产量构成比塔罗姆高，12.5.12.5 cm的行距比其他行距的产量高。在 27.5.27.5 厘米的排列下，哈马丹生产的丁香数量最多。此外，根据变量之间的相关性分析，鳞茎重量对大蒜产量的影响最大，鳞茎重量与鳞茎产量呈负相关（r₌ –0.60**）。一般而言，哈马丹品种的产量和产量构成比塔罗姆高，12.5.12.5 cm的行距比其他行距的产量高。
