春季在安巴尔省的石膏土壤中进行了田间试验，以确定珍珠岩水平（PL）、灌溉数量和间隔（IQ＆IT）对马铃薯生长和产量的影响。 PL 分别为 0%、4% 和 8%，具体取决于 30 厘米深度的土壤体积。两次 IT 3 天和 6 天后，IQ 水平分别为 NDI（净灌溉深度）的 100% 和 50%。随机完全区组设计 (RCBD) 中使用了分割-分割区组设计，具有 3 个重复。种植了马铃薯。根据蒸发盘 A 类安排灌溉。研究的性状为植物高度 (PLH)、植物干重 (PLDW)、植物叶面积 (PLA)、主要气生茎数量 (MASN) 和总产量 (YT)。对于 8% PL、3 天 IT 和 100% (NDI) 深度，PLH 的最高值为 67.17 cm。对于相同的 PL (8%)，6 天 IT 和 50% NDI，植物干重 (PLDW) 与 3 天 IT 和 100% NDI 相比降低了 15.69%。最高 YT 为 29 吨.ha-1，IT 时间为 3 天且 NDI 水平为 100%，而每 6 天灌溉一次且 NDI 水平为 50% 时，YT 为 19.5 吨.ha-1。
field experiment was conducted in Anbar province during spring in gypsiferous soil to determine the effects of Perlite levels (PL), quantity and intervals of irrigation (IQ & IT) on the growth and yield of potato. PLs were 0, 4, and 8% depends on soil volume to 30cm depth. IQ levels were, 100 and 50 % of NDI (net depth of irrigation) with two ITs 3 and 6 days. Split-split block design was used within Randomized Complete Block Design (RCBD) with 3 replicates. Potatoes were cultivated. Irrigation was scheduled depending on evaporation pan class A. The studied traits were plant height (PLH), plant dry weight (PLDW), plant leaf area (PLA), main aerial stems number (MASN) and total yield (YT). The highest value of PLH was 67.17 cm for 8% PL, 3 days ITs, and 100% (NDI) depth. For the same PL (8%) with 6 days ITs and 50% of NDI the plant dry weight (PLDW) was decreased by 15.69% compared to 3 days IT and 100% of NDI. The highest YT of 29 tons.ha-1 was achieved at IT of 3 days and level of 100% of NDI compared to 19.5 tons.ha-1 at irrigation every 6 days IT and 50% of NDI.
