چکیده مقاله :
به منظور تعیین دوره ی بحرانی تداخل علف های هرز با برنج، آزمایشی در سال 1393 در شهرستان های آمل و محمودآباد استان مازندران به صورت طرح بلوک های کامل تصادفی با 12 تیمار و در سه تکرار انجام شد. تیمارهای آزمایشی شامل شش دوره تداخل علف های هرز در فاصله زمانی 10،20،30،40 و50 روز پس از نشاءکاری برنج و سپس کنترل علف های هرز در ادامه فصل رشد، به علاوه یک تیمار تداخل تمام فصل، سری دوم شامل شش تیمار کنترل علف های هرز در فاصله زمانی 10،20،30،40 و50 روز پس از نشاءکاری برنج و سپس تداخل علف های هرز در ادامه فصل رشد، به علاوه یک تیمار کنترل تمام فصل بودند. نتایج حاصل از تجزیه واریانس تفاوت بسیار معنی داری را برای عملکرد دانه برنج درتیمارهای کنترل و تداخل در بین مکان ها و تیمارهای مختلف نشان داد. تداخل و کنترل علف های هرز در دو منطقه اثر بسیار معنی داری بر عملکرد دانه، تعداد دانه در خوشه و وزن هزار دانه به استثنای تعداد خوشه و عملکرد بیولوژیک داشتند. بالاترین عملکرد دانه از تیمار کنترل تمام فصل با میانگین عملکرد دانه 83/3010 و کمترین میزان آن از تیمار تداخل در تمام فصل با میانگین 2075 کیلوگرم در هکتار به دست آمدند. تیمار تداخل کامل نسبت به شاهد در عملکرد دانه به میزان 08/31 درصد، در تعداد خوشه 33/8 درصد و در تعداد دانه در خوشه 26/10 درصد حاصل شدند. دوره بحرانی کنترل علف های هرز بر مبنای مقادیر پنج و ده درصد افت مجاز عملکرد و از طریق برازش توابع غیرخطی رگرسیونی گامپرتز و لجستیک به داده های مربوطه به عملکرد نسبی، به ترتیب در تیمارهای عاری و آلوده به علف های هرز تعیین شد. نتایج نشان داد دوره بحرانی کنترل علف های هرز در محمود آباد با احتساب ده و پنج درصد افت مجاز عملکرد، به ترتیب در روزهای 22 تا 59 و 27 تا 36 روز بین مراحل ابتدا تا انتهای پنجه زنی بود. نقطه بحرانی در این منطقه 32 روز پس از نشاکاری تعیین گردید. در مزرعه آمل نیز دوره بحرانی با احتساب ده و پنج درصد افت مجاز عملکرد به ترتیب در روزهای 15 تا 54 و 20 تا 37 روز بین مراحل ابتدا تا انتهای پنجه زنی بودند. نقطه بحرانی در این منطقه 25 روز پس از نشاکاری بود. بنابراین، دوره بحرانی کنترل علف های هرز در آمل نسبت به محمودآباد زودتر شروع شده و دامنه آن نیز طولانی تر بود.
چکیده انگلیسی:
To investigate the effect of weed interference on the yield and yield components of rice an experiment was conducted in 2014 at Amol and Mahmoudabad cities in Mazandaran. The experiment was performed in a randomized complete block design with 12 treatments and three replications. Treatments to control weeds were of two types. The first treatment consistsed of controling weeds 10, 20, 30, 40, and 50 days after rice transplanting and then weeds interfered with plant during rest of growing season. A whole season weed control was used as check. The second type treatment at weed interference until 10, 20, 30, 40, and 50 days after rice transplanting and then weeds were controlled during rest of growing season. A whole season interference treatment was used as a weed infested check. The results of variance analysis showed a significant difference for grain yield in either weed free or weed infested treatments between two places. Weed control and interference (except panicle number and biological yield) significantly affected grain yield, grain numbers per panicle and 1000 grain weight. The highest grain yield (3010.83 kg.ha-1) belonged to weed control during whole growing season and lowest grain yield (2075 kg.ha-1) was obtained from weed infested check. Weed infested check resulted in lower grain yield (by 8.31%), panicle number (by 8.33%) and grains number per panicle (by 10.26%) as compared to the control. The critical period of weed control, based on the amount of 5 and 10 percent of yield losses, were fitted by Gompertz and Logestic regression to weed infested weed free treatments, respectively. The results showed that the critical period of weed control in Mahmoudabad region occurred during the days of 22 to 59 and 27 to 36 (from early to end of tillering) based on 10 and 5 percent of yield loss, respectively. The critical point was calculated to be 32 days after transplanting.Thecritical period for Amol region occurred during days of 15 to 54 and 20 to 37 (from early to end of tillering) based on 10 and 5 percent of yield loss, respectively. The critical point was calculated for day 25 after transplanting. In conclusion, the critical period of weed control seems to begin earlier in Amol than in Mahmoudabad and it also had a longer range.
