چکیده

به‌منظور بررسی تأثیر کودهای فسفر بر عملکرد و اسانس گیاه دارویی ریحانآزمایشی در قالب طرح بلوک‏های کامل تصادفی در سه تکرار در منطقۀ جیرفت انجام شد. تیمارها شامل: کود بارور 2 در سه سطح (20،10 و 25 گرم در هکتار)، کود گاوی در سه سطح (5، 10 و 15 تن در هکتار)، کودهای شیمیایی سوپرفسفات تریپل و فسفات آمونیوم هر کدام در سه سطح (50، 100 و 150 کیلوگرم در هکتار) و شاهد بودند. پس از اعمال تیمارها، صفاتی نظیر عملکرد، ارتفاع بوته، تعداد بذر، تعداد خوشه، وزن تک‌بوته، میزان اسانس، سطح برگ و تعداد برگ اندازه‏گیری شدند. نتایج نشان داد که اثر تیمارهای مختلف بر صفات، عملکرد، ارتفاع بوته، تعداد بذر، سطح برگ، درصد اسانس و وزن تک‌بوته در سطح احتمال یک‌درصد معنا‏دار شد و بر تعداد خوشه و تعداد برگ معنا‏دار نشد. تیمار کود گاوی بالاترین تأثیر را بر ارتفاع بوته، اسانس، وزن تک‌بوته، تعداد برگ و سطح برگ داشت. تیمار کود بارور 2 تنها بر تعداد بذر بیشترین تأثیر را داشت. تیمار کود سوپر‌فسفات تریپل بیشترین تأثیر را بر تعداد خوشه و سطح برگ داشت. در‌مجموع تیمار کود گاوی بیشترین تأثیر را در مقایسه با سایر تیمارهای استفاده‌شده داشت.

چکیده [English]

This study was conducted to evaluate the effect of fertilizers on the yield and essential oils of basil. This experiment was carried out in completely randomized block design with three replications in Jiroft area. The treatments included three levels of Barvar 2 (10, 20 and 25 g/ha), cow manure at three levels (5, 10 and 15 ton/ha), ammonium phosphate and superphosphate triple each at three levels (50, 100 and 150 kg/ha). Traits such as yield, plant height, seed number, panicle weight per plant, essential oil amount, leaf area, and leaf number were measured. The results showed that the treatments significantly affected yield, plant height, seed number, panicle weight per plant, essential oil amount, and leaf area at 1% level of significance but did not significantly affect the number of clusters and the leaf number. Cow manure treatment had the highest yield, plant height, essential oil, weight per plant, number of leaves and leaf area. Barvar 2 treatments had the highest effect only on the number of fertile seeds. Fertilizer treatments of superphosphate triple had the greatest impact on the number of leaf clusters. Overall, cow manures compared to other treatments had the highest impact.
