چکیده مقاله :

به¬منظور بررسی تاثیر کودهای زیستی نیتروکسین و فسفاته بارور 2 بر ویژگی‌های زراعی کنجد، آزمایشی به صورت فاکتوریل بر پایه طرح بلوک های کامل تصادفی با دو فاکتور و سه تکرار در سال زراعي 1393 در شهرستان خوي اجرا گردید. عامل اول فسفر در 3 سطح (شاهد، کود زیستی فسفاته بارور 2 همراه با 100 کیلوگرم در هکتار سوپر فسفات تریپل و 200 کیلوگرم در هکتار سوپر فسفات تریپل) و عامل دوم نیتروژن در 4 سطح (شاهد، نیتروکسین همراه با 100 کیلوگرم در هکتار اوره، نیتروکسین همراه با 150 کیلوگرم در هکتار اوره و 200 کیلوگرم در هکتار اوره) در نظر گرفته شدند. نتایج نشان داد که تاثیر کودهای زیستی فسفر بارور 2 و نیتروکسین روی ارتفاع بوته، تعداد شاخه فرعی در بوته، تعداد کپسول در بوته، تعداد دانه در کپسول، درصد روغن دانه، عملکرد دانه و شاخص برداشت معنی دار بودند. بیشترین عملکرد دانه به ترتیب به میزان های 4/1274 و 5/1232 کیلوگرم در هکتار در تیمارهای 200 کیلوگرم در هکتار سوپر فسفات تریپل و فسفاته بارور 2 همراه با 100 کیلوگرم در هکتار سوپر فسفات تریپل مشاهده شد. در مورد کود بیولوژیک نیتروکسین نیز بیشترین عملکرد دانه به ترتیب به میزان های 83/1264 و 12/1246 کیلوگرم در هکتار در تیمارهای با مصرف 200 کیلوگرم در هکتار اوره و مصرف 150 کیلوگرم در هکتار اوره همراه با نیتروکسین مشاهده شد. طبق نتایج این آزمایش با استفاده از کود زیستی فسفاته بارور 2 مصرف کود شیمیایی سوپر فسفات تریپل به میزان 50 درصد و همچنین با مصرف کود زیستی نیتروکسین، مصرف کود شیمیایی اوره به میزان 25 درصد کاهش یافت.

چکیده انگلیسی:

To study the impact of nitroxin and fertile phosphate 2 biofertilizers on the traits of sesame, an experiment was carried out in factorial on the completely random blocks with two factors and three replications in Khoy vicinity in 1393. The first factor was phosphorus in three levels ( control, fertile phosphate 2 biofertilizer with 100 kg/h super phosphate triple and 200 kg phosphate triple per hectare ); second factor was nitrogen in 4 levels ( control, nitroxin with 100 kg / h urea, nitroxin with 150 kg /h and 200 kg urea per hectare ). The results showed that the impact of fertile phosphorus 2 and nitroxin biofertilizers on the height of the stalk, the number of subsidiary bushes on the stalk, the number of capsules and the seeds in them, oil percentage and seed yield and harvesting index were significant. The highest seed yield was respectively 1274.4 and 1232.5 kg/h and 200kg/h super phosphate triple and fertile phosphate 2 treatment together with 100 kg/h super phosphate triple. The highest seed yield by 1264.83 and 1246.12 kg/h respectively belonged to nitroxin biologic fertilizer together with the consumption of 200 kg/h and 150 kg/h urea with nitroxin. The results of the experiments showed that the usage of fertile phosphate biofertilzer 2 decreased the consumption of super phosphare triple by 50 percent; and the usage of nitroxin biofertilizer reduced the consumption of urea chemical fertilizer by %25.
