The use of phosphate solubilising bacteria as inoculants simultaneously increases P uptake by the plants and hence improves crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium are among the most powerful Phosphate solubilisers. The principal mechanism for mineral phosphate solubilisation is the production of organic acids. Acid phosphatase plays a major role in the mineralization of organic phosphorous in soil. Several phosphatase encoding genes have been cloned and characterized. A few genes involved in mineral phosphate solubilisation have been isolated. Therefore, genetic manipulation of phosphate solubilising bacteria can improve plant growth. Synergistic effect of phosphate solubilising microorganisms on TCP solubilisation was highest when triple culture of Aspergillus niger, Aspergillus flavus and Trichoderma sp. was inoculated in NBRIP broth as compared to double and single inoculations.","PeriodicalId":14249,"journal":{"name":"International Journal of Pure & Applied Bioscience","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88155867","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}

A total of eight traits viz., leaf pubescence of blade surface, leaf length of blade, leaf width of blade, flag leaf, panicle awns, panicle presence of secondary branching, panicle secondary branching and panicle exertion were dimorphic. Three traits basal leaf sheath colour, leaf intensity of green colour, culm attitude were found to be trimorphic. Remaining three traits namely flag leaf attitude of blade, panicle curvature of main axis and panicle attitude of branches were found to be tetramorphic. The genotype mundamaranellu was found to be distinct for erect culm, erect flag leaf and presence of awns and these genotypes can be used as donor for rice breeding program. The cultivars Thondi and mullampunchan (106 days) were found to be early on days to 50% flowering among all the genotypes evaluated. All genotypes exhibited significant differences for eight quantitative traits. The high PCV and GCV was recorded for plant height, number of productive tillers and single plant yield. The highest heritability and high genetic advance as per cent of mean was observed in plant height, number of panicles per plant, number of productive tillers, 1000grain weight, single plant yield and these characters could be further improved by following simple selection procedure.","PeriodicalId":14249,"journal":{"name":"International Journal of Pure & Applied Bioscience","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81744616","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}

Forty one soybean genotypes along with five check varieties were arranged in RBD. The major insect pests observed at weekly intervals were leaf webber (Anarsia ephippias), aphid (Aphis glycines), leaf hopper (Bothrogonia indistincta), Pod bug (Riptortus pedestris) and blister beetle (Mylabris phalerata). The genotypes NRC 134 (4.20 no/mrl) and JS 20-17 (0.70 no/mrl) showed highest and lowest infestation by leaf webber. Highest infestation of aphid was found on PS 1613 (21.85no/3leaf) and lowest was found on AMS 100-39 (1.50 no/3leaf). In case of leaf hopper, the highest infestation was found on NRC 137 (4.75no/3leaf) and the lowest infestation was found on DSb 34 (1.08 no/3leaf). Genotypes namely NRC 137 (5.88 no/mrl) showed highest infestation and genotype JS 21-15 (1.23 no/mrl) showed lowest infestation by blister beetle.

No one source of nutrient usually suffices to maintain productivity and quality control in organic system. In addition, the inputs to supplement nutrient availability are often not uniform presenting additional challenges in meeting the nutrient requirement of crops in organic systems. With this concept, a field experiment was conducted at village Jahangirpur in Jewar Tehsil in Gautam Buddha Nagar district of Uttar Pradesh during 2014-2016 in rice-wheat cropping system. In this experiment, different treatments comprising organic amendments such as Blue Green Algae (BGA) 15kg/ha, SGM 10.0 tonne/ha, and Farm Yard Manure (FYM) 10.0 tonne/ha each applied alone or in combination were tested in organic crop production. These treatments were compared with absolute control (N0P0K0). For rice, a scented variety ‘Pusa Basmati 1’ were taken. The observations on grain yield, contents of Fe, Zn, Mn and Cu in rice grains, insect pest incidence, soil nutrients and microbial activity were taken. Results revealed a significant enhancement in grain yield of rice over absolute control due to the application of different organic amendments applied alone or in combinations. Rice grain yield increased by 114 to 116.8% over absolute control when all the 4 organic amendments were applied altogether. The rice grain yield (4.0 t ha-1) obtained under combined application of four organic amendments was at par with the yield recorded under recommended dose of chemical fertilizer application. An interesting observation recorded was that there was no serious attack of any insect pest or disease in organically grown crop. Soil microbial population (Actinomycetes, Bacteria, Fungi and BGA) enhanced due to the application of organic amendments in comparison to absolute control application that in turn resulted in a notable enhancement in soil dehydrogenase and phosphatase enzyme activity. Soil organic carbon and available phosphorus contents were also found to be significantly increased due to organic farming practice over control. Rice grain analysis for nutrients viz. Fe, Zn, Mn and Cu showed a significant increase in Fe and Mn content in the treatments having 2 or more organic amendments over control. Zn and Cu content also increased but the increment was significant with combined application of 2 or 3 organic amendments. The study revealed that addition of three organic amendments viz. BGA, SGM, and FYM could give the optimum yield (4.05 t/ha) of organic Basmati rice and improve grain and soil quality.","PeriodicalId":14249,"journal":{"name":"International Journal of Pure & Applied Bioscience","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81563654","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}

Genetic variability in plants can be used for developing improved cultivars with desirable traits. Present study focused on identifying genetic variability in 30 white yam genotypes (Dwarf, Semi dwarf and Tall) using 19 random oligonucleotide primers for RAPD analysis. On 19 RAPD primers, only 8 primers were selected based on their polymorphism and repeatability. Among the eight RAPD primers studied in white yam, OPW -16 was found be the best that produced ten polymorphic bands. All the primers evaluated resulted in 100% polymorphism. All the primers were recorded with high PIC value of >0.6. Dendrogram based on RAPD marker showed nine clusters at 0.8 dissimilarity level. It also shows the high divergence of the genotype V20 (DR17) and the clustering pattern indicates the grouping of the dwarf genotypes together.

Two Brassica vegetables viz. broccoli (Brassica oleracea) and kale (Brassica oleraceae l.var acephala) which, grown organically and conventionally were analysed for their phytochemicals content. The ascorbic acid content of organically grown broccoli and kale was 89.67±0.33 and 48.67±0.33 mg/100g which was comparatively higher when compared with inorganic counterparts with 84.80±0.40 and 43.33±0.67 mg/100g values respectively. The beta carotene content was found to be higher in case of organic broccoli i.e. 11.17±0.01 ppm as compared to 8.71±0.01 ppm in inorganic broccoli. The chlorophyll content was higher in case of inorganic broccoli (5.87±0.03 mg/L) and kale (8.31±0.01 mg/L). Simple phenol and flavanoids were found to be higher in case of organic kale as compared to inorganic kale. Total phenols, tannins and oxalates were found to be higher in inorganic broccoli and kale. Both broccoli and kale were good sources of pytochemicals. From the findings of the study concluded that they are rich in health–promoting phytochemicals so should be included in our food basket to provide protection against various diseases especially cancer. The cultivation and consumption of broccoli and kale should be promoted to harness their health promoting and health protecting beneficial effects. The phytochemical contents of the leafy vegetables serve as supplements for food and also have the potential to improve the health status of its users as a result of the presence of various compounds vital for good health.","PeriodicalId":14249,"journal":{"name":"International Journal of Pure & Applied Bioscience","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86832736","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}
