In field studies, pyroxsulam (12, 15 and 18 gha-1 ) and tank mix combination of sulfosulfuron + pyroxsulam at 12+12, 15+15 and 18+18 gha-1 without and with surfactant were evaluated for weed control in wheat and their carry over effect on succeeding sorghum crop. The weed control, particularly of the Phalaris minor was significantly poor, when pyroxsulam or its tank mix combination with sulfosulfuron were applied without surfactant compared to with surfactant (polyglycol 1000 ml ha-1). Pyroxsulam alone or in combination with sulfosulfuron provided excellent control of Avena ludoviciana. The optimum dose of tank mixture (TM) of sulfosulfuron + pyroxsulam was 18+18 gha-1 with 1000 ml ha-1 surfactant polyglycol. This combination was superior over sulfosulfuron, due to improved control of Rumex dentatus, thereby increased the wheat yield by 10-11% (on three years mean basis). The TM, sulfosulfuron + pyroxsulam with surfactant was similar to ready mixture Atlantis (mesosulfuron + iodosulfuron) at 14.4 (12+ 2.4) g a.i. ha-1 in controlling weeds and producing wheat yield. Pyroxsulam at 18 gha-1 was effective for control of diverse weed flora (Avena ludoviciana, Phalaris minor, Medicago denticulata and Lathyrus aphaca) under field and pot studies. The carry over effect of sulfosulfuron involving treatments (sulfosulfuron, sulfosulfuron + pyroxsulam) was observed on succeeding sorghum crop. At 18+18 gha-1 dose of sulfosulfuron + pyroxsulam, the average reduction in sorghum biomass was 44.5% in comparison to no herbicide treatment. Pyroxsulam effectively controlled the P. minor populations being susceptible as well as those resistant to fop and / or phenylurea herbicides. However, P. minor population resistant to sulfosulfuron showed the cross-resistance to pyroxsulam.","PeriodicalId":183623,"journal":{"name":"Wheat and Barley Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117286335","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 13 treatments consisted of three nitrogen levels (90, 120 and 150 kg N ha-1), two time of application (just before applying irrigations and about a week after irrigations when it was possible to walk in the field) and two schedule of application (three equal splits as 1/3rd basal, 1/3rd at first irrigation and 1/3rd at second irrigation; and four equal splits as 1/4th basal, 1/4th at first irrigation, 1/4th at second irrigation and1/4th at third irrigation) along with one absolute control. The study revealed that urea top dressed just before irrigation and nitrogen splitted in three equal doses led to better crop growth, yield attributes and yield of wheat leading to improved agronomic NUE (22.5-29.8 kg grain kg-1 applied N) than urea top dressed after irrigation and nitrogen splitting in four equal doses at all levels of nitrogen application (90-150 Kg ha-1). The highest wheat productivity was recorded with 150 kg N ha-1 applied in three splits with top dressing just before irrigation. Additional yield of 2.70-5.21q ha-1 (average 3.94 q ha-1) was produced when urea was applied just before irrigation as compared to urea top dressed after irrigatin.

Wheat pre-breeding and breeding may be based on secondary traits like chlorophyll content, chlorophyll fluorescence and grain number under heat stress. On the other hand, grain yield under heat stress can be improved by selecting genotypes for the rate of grain filling and for grain size. Wheat varieties with improved grain yield can be developed by integrating physiology and biotechnological tools with conventional breeding techniques during reproductive and grain-filling phases.

It feeds about 40 % of the world population by providing 20 % of total food calories and protein in human diet. It is highly challenged by various abiotic stresses such as drought, salt and heat stress during different growth and developmental stages leading to decreased total production. By altering physiological and metabolic processes, heat, salt and drought stress embarks major threat to the vegetative stage of plant growth and development (Boyer 1982). These stresses continue to be an important challenge to agricultural scientists to develop high performing genotypes. Plants response to heat, salinity and drought is highly negotiated by genotype, growth and developmental stage, duration of exposure, physiological, biochemical and molecular process leading to differential reprogramming of gene expressions (Chaves et al., 2003; Denby and Gehring, 2005; Flowers 2004; Langridge et al., 2006). Among the most important regulatory molecules, DREB family members are central in the regulation of effector molecules. DREB genes, found to be involved in stress signal transduction pathways (Ishitani et al., 1997; Knight et al., 1999; Lee et al., 2001), belong to a large DNA-binding protein family containing a conserved EREBP/AP2 domain (Pandey et al., 2014; Pandey et al., 2016). Different members of this family are able to regulate different processes such as stress response, hormone response and plant development functioning as trans-acting factors in separate signal transduction pathways (Riechmann and Meyerowitz 1998). Similarly, other genes such as NAC, TIR and SCl have also been reported to be involved in modulating the different abiotic stress responses in plants (Puranik et al., 2012).","PeriodicalId":183623,"journal":{"name":"Wheat and Barley Research","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114824683","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}

It is mainly grown as a rabi season crop in different temperate regions of the world including India. Barley is used as a feed for animals, malt for industrial uses and for human food. At present, Barley is subjected to various fungal, bacterial, viral and noninfectious diseases. The major barley diseases prevalent in the world as well as in India include leaf rust, covered and loose smut, spot or net blotch, powdery mildew, stripe disease, bacterial blight and molya. Stripe disease caused by Drechslera graminea (Telomorph: Pyrenophora graminea) is an important seed borne disease of barley and responsible for 21.6% 31.9% yield losses in Rajasthan. Moreover, yield loss up to 73% have also been reported where cultivation of susceptible cultivars are in practice (Mathur and Bhatnagar, 1991; Arabi et al., 2004). A range of systemic and contact fungicides are available as seed dresser for the seed borne disease control (Singh and Khetarpal, 2005). However, their continuous application not only disturbed the ecosystem, but also rendered the pathogen resistant for the fungicide (Soni et al., 2017). Hence, the use of resistant barley cultivars is one of the economic and best sustainable alternatives for controlling barley stripe disease. Therefore, screening of the available released varieties and genotypes of barley were carried out to identify the source of resistance against the pathogen of stripe disease of barley.","PeriodicalId":183623,"journal":{"name":"Wheat and Barley Research","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133281456","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}
