The data revealed that maximum weed number (45.6 m-2), weed fresh weight (20.6 g m-2), weed dry weight (6.3 g m-2) was observed under T1= No weeding (control). However, the maximum weed control (91.3%) was recorded under T7= Puma super 75 EW at 0.625 L ha-1, 50 reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS). The barley crop results revealed that maximum tillers (355.6 m-2), plant height (106.3 cm), spike length (11.5 cm), grains spike-2 (47.3), seed index (51 g), biological yield (11737 kg ha-1), grain yield (4493 kg ha-1) and harvest index (41.9%) was recorded under T7= Puma super 75 EW at 0.625 L ha-1 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS). Hence, current results manifested that proper application of puma super 75 EW at 0.625 L ha-1 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (50 DAS) produce maximum growth and yield parameters of barley crop. So, it was suggested that application of puma super 75 EW at 0.625 L ha-1, 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS) apply for getting higher yield (4493 kg ha-1) of barley crop. It was finalized that this study will be very fruitful for the future progress of barley production.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77061209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The laboratory studies were undertaken to confirm allelopathicity of its plant leachates and soil-decomposition plant residues towards emergence and seedling growth of rice. In first experiment, aqueous extracts from various plant parts of red sprangletop (stem, root, leaves, flower and entire plant) at their 5% (w/v) concentration were applied to germinating rice seeds. In second experiment, soil-decomposed red sprangletop plant residues of variable concentrations (2, 4 and 6% w/w) were used as germination media for rice. Among plant parts, red sprangletop leaves showed maximum allelopathic effect by fully inhibiting the germination of rice while its stem could be positioned at second situation as it caused 60, 73, 84.13 and 86 % reductions in germination percentage, germination index, seedling length and seedling dry biomass of rice as compared with control, respectively. This treatment also resulted in maximum delays in mean germination time (up to 4.80 days) and days taken to 50% germination (up to 4.40 days) of rice. The highest concentrated (6%) soil-decomposed plant residue of red sprangletop significantly diminished the germination percentage, germination index, seedling length and seedling vigor index that were 35.13, 23.26 and 41.61% lower than control. It very well may be presumed that liquid concentrates of leave and stem soil-decomposed plant residues of 6% concentration had different kind of allelochemicals that inhibited the germination, seedling growth and development of rice.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80682153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each experiment was laid-out in completely randomized design (CRD) having water levels and herbicides as treatments, replicated thrice. Five fragments of fresh rhizomes with active buds were placed in the soil in each pot for investigating the effect of various water regimes on re-sprouting of common reed. Sprouting were examined up to two months. While in the 2nd experiment post emergence herbicides were applied to the re-sprouts to check the efficacy of various herbicides against common reed management. Various water regimes affected the re-sprouting ability of common reed rhizomes. The lowest sprouting (6.66%) were noted for T8 (control) where no water was applied except at the time of placing the rhizomes in the pots, while maximum (96.66%) sprouting observed within (T3) water was applied from 5th to 7th weeks (5 times). While in the 2nd experiment herbicides significantly affected the re-sprouting ability, growth and biomass production of common reed and minimum re-sprouting and shoot biomass (3.33% and 6.00 g), respectively, were noted for fenoxaprop-p-ethyl as compared to control treatment (90.00% and 38.67 g) where no herbicide had been applied. Therefore it is concluded from the results that on either side from water regime T5 the re-sprouting ability decreases and buds mortality increases, which clearly indicates that common reed needs slightly moist soil to start the re-sprouting and do not need standing water during that period, while after re-sprouting it do needs water i.e. from 3rd weed onwards and dry conditions afterwards (T6-T8) cannot be tolerated. Therefore flooding common reed after cutting [1]for three weeks of draining and keeping them dry for 8 weeks can be used as cultural control method for common reed management, while in case of herbicides fenoxaprop-p-ethyl gives desirable results to control the common reed and to stop further infestation.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74401225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
