Avaliou-se a germinacao, o indice de velocidade de germinacao (IVG) e o tempo medio de germinacao (TMG). O GA 3 mostrou-se promotor eficiente para rapida germinacao de sementes de aracazeiro.

Therefore the proper level of fertilizers and appropriate methods is required to sustain the productivity of crops and soil fertility. Different levels of Nitrogen and its application methods were used to improve the canola productivity. A field experiment was conducted at University of Agriculture, Peshawar research farm in 2015-16. Randomized complete block design in split plot arrangement was applied with four replicates. Application methods (Broadcast method, rows one side placement, rows both side placement and rows between) were allotted to main plots and N levels (40, 70 and 90 kg ha-1) were allotted to subplots. Experimental results exhibit that all the parameter were significantly (p ≤ 0.05) different; maximum days to emergence (9), maximum number of plant m-2 (32), maximum days to first flowering (97), maximum grain pod-1 (28), maximum 1000 grain weight (3.2 g), maximum grain yield (985 kg ha-1) were noted at plot that fertilized with 70 kg ha-1 N along with both side placement of rows. It can be concluded that N at 70 kg ha-1 and both side placement of rows produce a higher yield and yield attributes of canola.","PeriodicalId":42771,"journal":{"name":"Applied Research & Agrotechnology","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81477132","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}

Kinnow mandarin is dominant cultivated in the plain of the Punjab, Pakistan. Being a perennial crop, citrus is more vulnerable to changing environmental conditions and both physical and biochemical quality parameters are deteriorated by erratic behavior of weather around the year. The present study was conducted to assess the impact of climate change on citrus industry of Pakistan and selected three main citrus groves of the Punjab province. The selected orchards were uniform in age, vigor and planting geometry by using factorial (RCBD) while survey design was performed to assess impact of climate change on Kinnow fruit industry. Climate change has triggered pest’s infestation, disease incidence and water use and ultimately increased inputs cost. Heat and drought stress and fog was more observed in Vehari and Toba Tek Singh (TTS) and more yield reduction and low quality was recorded in these districts than Sargodha. Processing cost increased and more export risk was seen with market fluctuation in climate change scenario. Increased in input cost, water requirement of plant, reduction in net return and uncertain market were observed. Climate change has directly affected citrus industry and scientific approach requires addressing these challenges.","PeriodicalId":42771,"journal":{"name":"Applied Research & Agrotechnology","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83781579","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}

Como el cultivo de maiz requiere suelos de alta fertilidade el potencial osmotico de estos suelos normalmente es negativo. Por lo tanto, el uso de semillas vigorosas brinda mayores oportunidades para el establecimiento de plantas en el campo, y el factor genetico tambien puede actuar en estas situaciones. Por lo tanto, el objetivo de este trabajo fue investigar la influencia del genotipo y el vigor del maiz en el desarrollo de las plantulas bajo el efecto del potencial osmotico. Se utilizaron semillas de dos cultivares hibridos simples (30F35R y 30P70H), cada uno representado por tres lotes con diferencias de vigor, inicialmente evaluados por la determinacion del contenido de agua y la emergencia de las plantulas en el campo. Los tratamientos de estres osmotico probados fueron: cero; -0,1; -0,2; -0,3; -0.4 y -0.6 MPa, obtenido con solucion de polietilenglicol 6000. Se concluye que en situaciones de suelos con potencial osmotico negativo, la influencia del vigor de las semillas de maiz en el establecimiento del stand es relevante, especialmente cuando el genotipo presenta caracteristicas de tolerancia al estres hidrico.","PeriodicalId":42771,"journal":{"name":"Applied Research & Agrotechnology","volume":"2015 1","pages":"65-73"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73894032","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}

Frutos imersos em ethephon apresentaram cor da casca 100% amarela apos 14 dias (tres dias antes do tratamento controle). Cor da polpa, espessura da casca, perda de massa e pH nao diferiram entre os tratamentos, bem como AT, SS e ratio apresentaram semelhancas. O rendimento de polpa obedeceu ao nivel requerido pela industria em ambos os casos.
