To attain the food needs of the world’s growing population, further increase in rice productivity is needed. To assess the sensitivity of agricultural output, a greater comprehension of the possible interactions amongst crops and weeds in the face of climate change, especially under elevated CO 2 (EC) and elevated temperature (ET), is essential. This study was conducted to quantify the influence of elevated temperature, CO 2 , weed density and their interactions on crop-weed competition, rice yield parameters and grain yield. The experiment was conducted in four separate Open Top Chambers (OTCs), viz . with ambient CO 2 (A), elevated CO 2 [550±50 ppm] (EC), elevated temperature (ambient±2 °C) (ET) and combined effect of elevated CO 2 and temperature (EC+ET) with and without weed competition. The EC alone enhanced the rice grain yield by 42.30% in weed-free conditions when compared to ambient CO 2 , however substantial change was not observed under ET. In the EC+ET condition, however, regardless of weeds presence or absence, crop output was reduced by 22.02 percent. Alternanthera paronychioides A. St.-Hil. competition caused rice yield reduction of 79.72, 83.04, 62.98 and 62.01% at A, EC, ET, EC+ET, respectively . The EC and ET interactions will certainly exert a profound influence on weed growth and competition against crops, which ultimately enhances crop yield losses in futuristic climate change scenario.","PeriodicalId":13467,"journal":{"name":"INDIAN JOURNAL OF WEED SCIENCE","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83801053","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 CA has paved the way for cultivation of pulses in diverse cropping systems. A field experiment was conducted at ICAR-Indian Agricultural Research Institute, New Delhi during 2018-19 and 2019-20 cropping cycle with summer greengram in maize-wheat system to assess the effects of CA on weed interference, crop productivity and resource use efficiency. Results showed that CA-based practices with residue retention resulted in a considerable reduction in weed density and biomass when compared to conventional tillage (CT). Greengram yield parameters in CA were higher than in CT. The permanent broad bed (PBB) with residue retention (R) and recommended 100% N application (100N) (~PBB+R+100N) gave ~56% higher greengram grain yield than CT with considerably higher water productivity, nutrient-use efficiency and net returns. The adoption of CA practice involving PBB+R in greengram led to higher weed control efficiency and was more productive, remunerative and irrigation water-use efficient. Thus, it could potentially boost up the greengram productivity, profitability and resource-use efficiency under maize-wheat-greengram system in north-western Indo-Gangetic Plains (IGP) of India.","PeriodicalId":13467,"journal":{"name":"INDIAN JOURNAL OF WEED SCIENCE","volume":"122 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76383484","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 experiment was laid out in a randomized block design with ten treatments and three replications. The crop was sown as per the package of practices recommended for zone Kymore Plateau of Madhya Pradesh. The major monocot weed was Cynodon dactylon and dominant dicot weed was Chenopodium album at 30 days after sowing (DAS). At 30 DAS, significantly lower weed density (7.75/m 2 ) and biomass (2.70 g/m 2 ) were recorded with post-emergence application (PoE) of fomesafen (11.1% W/W) 220 g + fluazifop-p-butyl (11.1% W/W) 220 g/ha PoE at 20 DAS, followed by imazethapyr (35%) + imazamox (35%) 100 g/ha PoE at 20 DAS. The lowest weed index was noted with imazethapyr 55 g/ha PoE followed by pre-emergence application (PE) of pendimethalin 0.75 kg/ha and fomesafen 220 g + fluazifop-p-butyl 220 g/ha PoE at 30 DAS. Higher weed control efficiency (WCE) at 30 DAS was recorded with fomesafen 220 g + fluazifop-p-butyl 220 g/ha (70.6%) followed by hand weeding at 20 and 40 DAS (57.1%). However, fomesafen 220 g + fluazifop-p-butyl 220 g/ha PoE at 20 DAS and imazethapyr + imazamox 100 g/ha PoE at 20 DAS caused severe injury to chickpea plants and even mortality of a few plants. Significantly higher 1000 seed weight (183.0 g) and grain yield (1.79 t/ha) were observed with imazethapyr 55 g/ha PoE which was statistically at par with weed free check. Significantly higher net returns ( 70746/ha) and B:C ratio (3.97) were recorded with imazethapyr 55 g/ha PoE ( 70746/ha), followed by pendimethalin 0.75 kg/ha PE. The monetary efficiency ( 589.5/ha/day) of imazethapyr 55 g/ha PoE was statistically at par with weed free ( 541.3/ha/day) and was significantly higher than all other treatments.","PeriodicalId":13467,"journal":{"name":"INDIAN JOURNAL OF WEED SCIENCE","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84689580","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}
