Samplings were made during pre-monsoon; monsoon and post-monsoon sampling have been carried out for the duration of 2 years. The study deals with the occurrence of cyanobacterial species in five different aquatic habitats in Kaiga region, with respect to a change in the physico-chemical properties of water. The cyanobacterial diversity is maximum in monsoon season compared to post-monsoon; it was least during pre-monsoon. Among cyanobacteria non-heterocystous filamentous forms were dominant followed by unicellular forms, whereas heterocystous forms were least in number. It was also found that the physicho-chemical properties of water have the influence on the richness of cyanobacterial community. This study indicates the maximum occurrence and abundance of Chroococaceae (23.73%) and Phormidaceae (18.64%) members in all the sites, whereas Stigonemataceae (1.7%) shows very less occurrence. Among the cyanobacteria identified non-heterocystous filamentous forms were dominant followed by unicellular forms; whereas heterocystous forms were least in number.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"67 5 1","pages":"10-18"},"PeriodicalIF":0.0,"publicationDate":"2015-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88472824","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}

This study was conducted to determine the effect of long-term application of various levels of Nitrogen (N), Phosphorus (P), Potassium (K) and organic nutrients on HLB disease of wheat. The experiment was super imposed on long-term fertility experiment conducted in RCB design with three replications under rice- wheat cropping pattern at National wheat research program (NWRP), Bhairahawa, Nepal. The treatments include various combinations of 100 kg Nitrogen/ha, 0 and 60 kg Phosphorus/ha and 0, 50 and 100 kg Potash /ha with or without Sesbania ( Sesbania cannabina ) and Farm Yard Manure (FYM). Area under disease progress curve was calculated using the disease scores and yield parameters were recorded. Among the inorganic nutrients, long-term deficiency of potash in the field markedly enhances the HLB disease. Application of phosphorus in various doses increased the HLB severity in absence of potash. Regular application of at least 50 kg potash/ha in wheat noticeably reduced the HLB disease. Regular use of FYM 10 ton/ha for long term considerably reduced the HLB disease but long term use of Sesbania as green manure hadn’t any impact on HLB severity. Inclusion of potash in nutrients considerably increased the yield and thousand-grain weight (TGW) of wheat. In long term, balanced use of inorganic and organic nutrients with special attention on regular inclusion of potash and FYM in the nutrient combinations is vital in suppression of HLB disease under rice-wheat cropping pattern.

Application of balanced fertilizers alone is not only the solution for this problem, application of residue free nutrients that protects the soil health and environment is very important. Here comes the concept of organic farming. Hence, a field experiment was conducted in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar to study the effect of organic nutrients on growth and physiological parameters of radish. The experiment was conducted with eighteen treatments in three replications and laid out in FRBD design. The treatment includes various sources of organic manures viz., FYM, vermicompost, enriched manure along with and without use of consortium biofertilizer. Biostimulants viz., buttermilk solution and EMI were given as foliar spray at 15 d interval as 2 sprays. The intercultural operations and plant protection measures were carried out as per the recommendation. The results of the experiment revealed that application of farm yard manure @ 25 t ha-1 along with consortium biofertilizer @ 2 Kg ha-1 and EMI @ 1:1000 dilution ha1 as foliar application recorded the highest growth parameters viz., shoot length, number of leaves and shoot weight. The physiological parameters viz., leaf area and chlorophyll content were recorded the highest in the same treatment T6.","PeriodicalId":22829,"journal":{"name":"The Journal of Phytology","volume":"53 1","pages":"40-42"},"PeriodicalIF":0.0,"publicationDate":"1970-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82280286","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}
