Abstract:

The past couple of decades, plant growth promoting rhizobacteria (PGPR) will begin to replace the use of chemicals in agriculture, horticulture, silviculture and environmental cleanup strategies. Scientific researchers involve multidisciplinary approaches to understand adaptation of PGPR, effects on plant physiology and growth induced systemic resistance, biocontrol of plant pathogens and biofertilization. PGPR are naturally occurring soil bacteria that aggressively colonize in plant roots and play a vital role in crop protection, growth promotion and in the improvement of soil health. The study was conducted to isolate plant growth promoting rhizobacteria from sugarcane rhizosphere and assess their potential with combination of chitosan for plant growth and biocontrol activities. Isolated rhizobacteria were characterized by morphological, physiological, biochemical and molecular identification of bacteria by 16S rRNA sequencing. They were screened in vitro plant growth promoting traits viz., production of Indole acetic acid, Hydrogen cyanide, Ammonia production and antifungal activity against Colletotrichum falcatum. Five isolates showed highest plant growth promoting activities. All isolates identified as Enterobacter hormaechei, Bacillus megaterium, Bacillus cereus, Bacillus thuringiensis and Bacillus pumilus. For biocontrol activities against Colletotrichum falcatum, the significant growth inhibition was observed. This study was further preceded in sugarcane. Sugarcane setts were soaked into PGPR and chitosan solution for 12 hours. Germination percentage, growth parameters, chlorophyll, proline content, nitrate reductase activity, anti-oxidative enzyme superoxide dismutase activity showed significant findings. The study is suggesting that PGPR and chitosan can be used as an effective biological fertilizer combination for increasing sugarcane production.

Abstract:

The detection of pigments in cacao pods together with colorless flavonoids serves as a useful indicator for pod maturity using a fast and non-destructive multi-parametric fluorescence sensor. In this study, the contents of anthocyanin, flavonol, chlorophyll and nitrogen balance of five cacao genotypes (DESA1, KKM22, KKM25, MCBC1 and PBC221) were determined monthly (1-5 months) after flower pollination. There were significant differences (P≤0.05) observed between the interaction of five different cacao clones and pod development periods in flavonol, chlorophyll and nitrogen balance contents. As pods developed, anthocyanin and flavonol accumulated while the content of chlorophyll decreased only when pod matured with nitrogen balance showed a decreasing trend in cacao pods. Among these clones, as expected, natural red appearance in cacao pods of DESA1 showed significantly highest index of anthocyanin (0.637), following by KKM22 (0.255). In addition, there was no significant difference observed in KKM25, MCBC1 and PBC221 for anthocyanin content. During pod development, MCBC1 showed the least content in flavonol (P≤0.05) and the chlorophyll contents in KKM22 and MCBC1 were lower compared to other clones. UPLC-QTOF analysis showed that major components found at the cacao peel extracts of the pods consisted of flavonoid and procyanidin which are commonly found in cacao beans. Besides phenolic compounds, the presence of methyl xanthine (theobromine and caffeine) was found in cacao peel. As a conclusion, non-destructive fluorescence-based indices can be used to measure the pigments and flavonoids in cacao which can provide valuable non-destructive indicators for cacao pod maturity across different cacao cultivars.

Biography:

Osondu Chimezie Nworu loves those who rule over their people in righteousness and in the fear of God because he strongly believes that successful management of cultural pluralism and diversity becomes an inborn skill on anyone in a position of authority when the one rules with love. That is the reason he is continually researching, evaluating, exposing and denouncing with scientific articles to educate people, governments and organization that displace, marginalize, persecute, devastate people and environments whether the people maltreated are  Ibos, Ogonis, Niger Deltans, and Rohingyas etc. The approach is the same, he sees his works as a means - using intellectualism to educate and promote public awareness of stampede human rights and hidden injustice by corrupt governments in Nigeria and elsewhere that showcases the contrary and do not devote time to thinking of the people

Abstract:

No one can underrate the much significant contributions and potentials for Agriculture in the totality of the Nigerian economy. The key to developing agriculture in Nigeria is studying, researching and identify means to effectively support the small-scale farming practiced by a majority of the populace. The paper is not advocating the abandonment of the medium and large-scale farming levels, but the small-scaled and scattered farming that are prevalently practiced has evinced the needs to empower more this category through receiving more support from aid donors and the governments. Therefore, identifying ways to encourage this level of farming is vital, though presently more emphasis is being given to the middle and large-scale farming resulting in no visible increase of the gross national products. And for a fact that the above 75 percent of the population that engages in agriculture even the percentage gets to about 95 in most urban and in the rural areas during the rainy season are small-scale farmers. These are the lots of the small-scale farmers that cultivate the greatest part (90%) of the 83 million hectares of the 98 million hectares arable land mass. As in Nigeria small-scale farming accounts for about 95% of total agricultural output - Federal Ministry of Agriculture, 2005 (CTA, 2008)

Since, agricultural science is so a broad multidisciplinary field the goal to pursue self-sufficient in food production to ameliorate the lives of the masses by improving the capacity of the small-scale farmers who effectively produce almost the food consumed through the innovative applications of some parts of the discipline of agricultural science. Especially, by applying Soil Science, and Production techniques like irrigation management, recommended nitrogen inputs etc. thereby improving the agricultural productivity, optimally dissemination of information and free urban/rural farming vocation skills pieces of training. Apparently, applying the value and practical implementation of agricultural science such as soil science and  Science Production techniques to Nigerian agriculture shall invariably enhance productivity and distance the farmers from the stress of relying always on seasonal rainfall and bush fallow system especially in the Niger Delta region where family farming was prevalent and gas flaring rate is high  and UNEP in Ogoniland (topsoil) clean-up operations would ameliorate the environment so as to grow healthier efficient crops for consumption.

Abstract:

The Chitosan, which is biodegradable, non-toxic and biocompatible non-allergenic has been shown to be particularly useful in many fields including food, cosmetics, biomedicine, agriculture and possess versatile functional properties such as antitumor enhancing properties, immunostimulating effects, antimicrobial activity, free radical scavenging activity arthritis controlling activity. Chitosan shows its biological activity only in acidic medium because of its poor solubility at pH above 6.5 and low absorbability of non-digestible and high molecular polysaccharides. In this respect, chitosan oligosaccharides, because of their shorter chain length, display a reduced viscosity and are soluble in aqueous media at pH values close to neutrality, which increases their bioavailability and opens a wide range of new potential applications. Keeping in mind the above biomedical aspects of chitosan the present study has been conducted to investigate the therapeutic effect of chitooligosaccharides in diabetes mellitus, the study showed that blood glucose, urea and creatinine were decreased in diabetic mice administered with chitooligosaccharides. Chitooligosaccharides  lowered the serum SGOT and SGPT levels which reveals the protective effect and normal functioning of liver in reversing the organ damage due to diabetes which clearly observed by high levels of serum transaminases in diabetic control. Chitooligosaccharides also resulted a significant recovery in the levels of biosensors of lipid profile. chitooligosaccharides therapy increased the activity of catalase and superoxide dismutase in hepatic tissues of treated diabetic mice. The work exposes that chitooligosaccharides has significant effect for curing diabetic mellitus and related complications.

Abstract:

Sweet flag (Acorus calamus Linn.) is an important littoral plant widely used in traditional medicine since times immemorial. Four cytotypes, viz., diploid, triploid, tetraploid and hexaploid are found world-wide. Two cytotypes, viz., diploid and triploid are found in Manipur, India. Different cytotypes show wide variations in morphology and chemical composition of essential oils in rhizomes and leaves. The plants is used for anti-spasmodic, anti-diarrhoeic, carminative, anti-helminthic, anti-depressant and CNS anxiolytic properties, as tonic, stimulant and aphrodisiac, for treating rheumatism, toothache and respiratory ailments. The aromatic oils are used for flavoring alcoholic beverages and as fragrances in perfumes and sacred oils. The crude extract can prevent acrylamide-induced limb paralysis and increase dopamine receptor in corpus striatum, prevent noise stress-induced changes in rat brain and significant hypolipidemic activities. Bioactive molecules present are acorin, α- and β-asarone, asaryldehyde, caryophylene, isoasarone, methyl isoeugenol and safrol. β-asarone content varies with ploidy level. Triploids contain 7-7.8% β-asarone as against 73-88% in tetraploids. Diploids do not contain β-asarone which is known carcinogen. Chinese medicine suggests its beneficial effects on memory disorder, learning performance and senescence. Clonal propagation of diploid and triploid cytotypes have been developed using dual-phase culture. Microrhizome induction for propagation has significance in conservational and sustainable development priorities. Accessions across nineteen different populations have been investigated. RAPD and ISSR markers have been employed for understanding genetic variabilities of the species. Amplification of genomic DNAs reveals 35.3% polymorphism.  Marker indices and resolving powers indicate that ISSR markers are more efficient. Similarity matrix has been used to construct dendrogram based on UPGMA analysis and grouped accessions into two clusters in tune with ploidy level.

Abstract:

Sustained self-sufficiency and March towards food and nutritional security depend on crop improvement in rapidly limiting natural resources. Besides cereals, pulse production now needs understanding of intricate physiology by utilizing judiciously devised cutting edge technologies and consequently to develop climate resilient desirable genotypes with breeders and biotechnologists for relentlessly enhanced productivity. Abiotic stresses: drought, salinity, heat and flooding affect photosynthesis, nitrogen assimilation, protein synthesis, pollination and fertilization. In our experiments, seed hardened and foliage applied salicylic acid (SA) significantly alleviated salinity and drought in pea and chickpea respectively; brassinolide and micronutrient zinc individually mitigated salinity, whereas paclobutrazol alleviated harmful effects of flash flooding in mungbean by producing aerial roots with initiating arenchymatous tissue in roots. SA @ 1.0 to 1.5 mM; brassinolide @ 0.05mM and paclobutrazol @ 10 ppm provided protection against stresses (drought, salinity, heat and flash flooding) at critical developmental stages of seedling growth, reproduction (pollen formation, pollen, germination, fertilization) and seed development. Encouraging findings regarding SA induced micronutrients uptake with improved cellular metabolism through improved water use efficiency, enhanced antioxidative ezymes activity and synthesis of antioxidants of compatible nature under abiotic stresses were recorded, which helped in elucidating the underlying mechanisms for tolerance in crop plants. Conclusion and Significance: Stress tolerance may be achieved by the maintenance, activation, and enhanced function of physiological systems that are especially sensitive to disruption by increased levels of stress. Information on stress-inducible genes, genetic control of stress responses and signaling pathways offer a chance for creating a clearer picture of plant responses and adaptations to different stresses.

Biography:

Xiaochuang Cao has his expertise in plant nutrition and rice high yield cultivation technology. Recently, he focused to explain why the mixed-N (NO₃^-+NH₄⁺) nutrition enhances rice growth under water-deficit condition, from the aspects of photosynthesis, root-shoot carbon partitioning, and hormone signaling. His results provide new insights for improving plant tolerance to water stress via nutrient resource management in certain drought-prone
regions.

Abstract:

To investigate the response of rice growth to nitrogen forms under water-deficit condition, and its intrinsic mechanisms involved in photosynthesis, hormone signaling and root-shoot photoassimilates partitioning. A hydroponic experiment supplying different N forms (NO₃^-, NH₄⁺, NO₃^-+NH₄⁺) was conducted in a greenhouse under water stress.Water stress significantly inhibited rice biomass, leaf area, leaf chlorophyll and Rubisco contents. However, mixed-N nutrition substantially alleviated these inhibitions compared with NO₃^- nutrition. Mixed-N nutrition maintained a higher, ETR, ФPSII and NP, thus causing higher photosynthesis and photochemical efficiency. Water stress up-regulated leaf SPS, but reduced leaf InvA. Water stress decreased IAA in leaf and cytokinins in root, and their contents in mixed-N nutrition were higher than those in NO₃^- nutrition. In mixed-N nutrition, the up-regulation of leaf SPS and IAA and the reduction of SSc and InvA in roots jointly resulted in the accumulation of sucrose in leaves and the inhibition of its transportation to roots, finally reducing R/S.The inhibited R/S reduces the photosynthate for root redundant growth, but provides more photosynthate for shoots, also increases its drought tolerance. We concluded that the strengthened water-deficit tolerance in mixed-N-supplied rice seedlings is closely associated with the improvement of photosynthesis and photochemical efficiency, hormone balance and root-shoot carbon partitioning.

Abstract:

Statement of the Problem: The plants can absorb Pb from leaf depositions that lead to elevated Pb concentration in plants even when there is a low level of Pb in soils and/or irrigation water. In urban and peri-urban agricultural areas, the valid assessment of low Pb accumulation by plant species/genotypes is necessary for the successful production of Pb safe food crops.

Methodology & Theoretical Orientation: A pot study was conducted to evaluate the effect of foliar application of Pb salts on growth, physiological processes and tissue concentration of Pb in rice. The present study was comprised of two factors: a) foliar application of Pb at 25 mg L^-1 as lead chloride (PbCl₂) and lead nitrate i.e., Pb(NO₃)₂, along with an uncontaminated control and b) fourteen rice genotypes, arranged in completely randomized block design each with three replications.

Findings: The results showed a devastating nature of Pb(NO₃)₂ treatment than PbCl₂ on growth such as plant height, straw dry matter and yield, and physiological attributes like photosynthetic rate, transpiration rate, stomatal conductance of rice genotypes. Among rice genotypes, with foliar Pb application, Shaheen Basmati and KS-282 showed better growth, yield and physiological attributes, low Pb concentration in rice straw and paddy.

Conclusion & Significance: These both rice genotypes were identified as a valuable resource that can be used by farmers or in advance rice breeding programs targeted to increased Pb tolerance. Regarding the additional practical significance, the present study was under taken to capitalize the differences in toxicities of foliar applied Pb salts on rice genotypes, considering various anthropogenic sources of Pb pollution with associated risks of accompanying anions like Cl^- and NO₃^- in the environment.

Srikrushna Behera, he is working at Krishi Vigyan Kendra, Bhawnipatna,(OUAT), Odisha, India. His research is on "Effect of Plant Growth Regulators on Morpho-Physiological And Yield Parameters Of Some Sesame (Sesamum Indicum L.)  Cultivars".

Abstract:

The present experiment was conducted in the Central farm, OUAT during Rabi season 2014-15 with five sesame varieties viz. Uma, Amrit, Smarak, Prachi and  Nirmala to find the efficiency of growth regulators such as NAA, GA₃ and IAA in two Conc. (10 ppm and 20 ppm ) sprayed at 30 and 45 DAS. The experiment was laid out in split-plot design with three replications. The Morpho-physiological observations were recorded at different stages of growth of all the varieties due to effect of growth regulators. Significant increase was observed in response to growth regulator on germination of seeds. The highest percentage of seed germination was recorded in GA₃ 20 ppm (98.51%). Due to spraying of growth regulators there was increase of plant height, number of branches and leaf area per plant in all the treatments irrespective of varieties and the highest value was exhibited by Nirmala as regards to above characters. The LAI, RGR, NAR, CGR & LAD were found to be increased in PGRs treatments over the control. Among the varieties Nirmala exhibited highest value followed by Amrit. The yield attributing characters such as total dry matter, number of capsules/ plant, number of seeds per capsules and 1000 seed weight were significantly increased among the treatments as well as varieties. Due to the spraying of plant growth regulators the percentage of increase in yield ranged from to a tune of 0.5 % in GA₃ 10 ppm conc. to 24 % in GA₃ 20 ppm conc. over the control. Among the varieties highest yield was noted in Nirmala (5.60 q/ha) followed by Amrit (5.08 q/ha). In view of the present findings Nirmala was found to be the highest yielder and higher concentrations of plant growth regulators were found to be more significant over the control.
