Nano particles are finding their way into the environment through deliberate and accidental actions, ecotoxicological properties and the risks of these nano particles have yet not been fully characterized. In this present investigation, experiments were carried out to know the effect of Cu oxide-nano particles （〈 50 nm） on germination and growth of seeds of soybean and chickpea. In both the crops, germination was not checked up to 2,000 ppm Cu （applied through Cu oxide-nano particles）, but the root growth was prevented above 500 ppm Cu. With increasing concentration of NPs, the elongation of the roots was severely inhibited as compared to that in control. In many cases root necrosis was occurred. Massive adsorption of Cu oxide-nano particles into the root system was responsible for the toxicity. A parallel experiment was also carried out to know the effect of copper sulphate solution on seed germination, above 200 ppm Cu, it restricted the germination of seeds, because of high salinity.

The development of single electrode with multifunctional purposes for electrochemical devices remains a symbolic challenge in recent *** work explores interfacially-rich transition metal nitride hybrid that consist of nickel nitride and vanadium oxynitride(VO_(0.26)N_(0.52))on robust carbon fiber(denoted CF/Ni_(3)N/VON)as trifunctional electrode for hydrogen evolution reaction(HER),oxygen evolution reaction(OER),and sodium ion batteries(SIBs).The as-prepared CF/Ni_(3)N/VON exhibits low HER overpotential of 48 m V@10 m A cm^(-2),OER overpotential of 287 m V@10 m A cm^(-2),and sodium-ion anode storage reversible capacity of 555 m A h g^(-1)@0.2 *** analyses reveal that the Ni_(3)N effectively facilitates hydrogen desorption for HER,increases the electrical conductivity for OER,and promotes the Na-ion storage intercalation process,while the VON substantially elevates the water dissociation kinetics for HER,accelerates the adsorption of OH*intermediate for OER and enhances the Na-ion surface adsorption storage *** to the excellent HER and OER performances of the CF/Ni_(3)N/VON electrode,an overall water splitting device denoted as CF/Ni_(3)N/VON//CF/Ni_(3)N/VON was not only assembled showing an operating voltage of 1.63 V at current density of 10 m A cm^(-2)but was also successfully self-powered by the assembled CF/Ni_(3)N/VON//CF/Na_(3)V_(2)(PO_(4))_(3) flexible sodium ion *** work will contribute to the development of efficient and cost-effective flexible integrated electrochemical energy devices.

A flexible carbon fiber-confined yolk-shelled silicon-based composite is reported as an anode material for lithium storage *** nanoparticles(Si NPs)are confined by the N-doped hollow carbon cages(SiNHC)and these uniform dispersed yolk-shell-structured Si-NHC units were encapsulated by the carbon fibers within an interconnected three-dimensional(3D)framework(Si-NHC@CNFs).For the encapsulated yolkshelled Si-NHC,the void space between the inner Si NPs and outer NHC can accommodate the structural changes of Si NPs during charging/discharging processes,leading to effectively improved structural stability and cycling *** importantly,all the Si-NHC units were bridged together through a conductive CNFs"highway"to enhance the overall conductivity and tap density *** observed,Si-NHC@CNFs exhibited an initial discharge capacity of 1364.1 mAh·g^(-1)at 1000 mA·g^(-1)and678.9 mAh·g^(-1)at 2000 mA·g^(-1).Furthermore,the reversible capacity was well maintained at 752.2 mAh·g^(-1)at500 mA·g^(-1)after 6000 ultra-long cycles.

Sustaining rice （Oryza sativa L.） productivity at high level is a great challenge, particularly in areas where rice productivity declines in spite of following recommended nutrient management practices. Nutrient management by integrating organic manures, inorganic fertilizers and biofertilizers may play an important role in improving and sustaining rice productivity. In this study, the authors tried to evaluate the suitable proportion of organic manures and inorganic fertilizers along with biofertilizer to maximize growth and productivity of hybrid rice on sandy-loam lateritic soils of West Bengal, India. The crop having 50% recommended dose of fertilizer （RDF）＋ 50% recommended dose of nitrogen （RDN） through mustard oil cake （MOC） and 75% RDF ＋ 25% RDN through MOC ＋ biofertilizer significantly increased plant height, number of tillers/m2, leaf area index （LAI）, dry matter accumulation （DMA） and crop growth rate （CGR） at initial and vital period of grain growth over those of 25% RDF ＋ 75% RDN through MOC and 100% RDN through MOC. The former two treatments also increased number of panicles/m2 and number of grains/panicle over those of only organic manuring （100% RDN） or only chemical fertilization （100% RDF） or 25% RDF ＋ 75% RDN through MOC. Crop with 75% RDF ＋ 25% RDN through MOC ＋ biofertilizer or 50% RDF ＋ 50% RDN through MOC produced 20.2%-33.8% higher grain yield and 11.0%-33.3% greater straw yield, and paid higher gross and net returns over other treatments. This study suggests growing hybrid rice with 75% RDF ＋ 25% RDN through MOC ＋ biofertilizer or 50% RDF ＋ 50% RDN through MOC for better growth, higher productivity and greater profit.

Farmers of North-Eastern India grow ginger organically and obtain low yield. Biofertilizer may help in increasing yield and maintaining soil fertility. An investigation made with different biofertilizers showed that seed treatment with biofertilizer increased biomass by 18.3%, enhanced N, P and K removal and improved short-term soil fertility status by increasing N and P balance and reducing negative K balance over control plots. Use of high dose （5.0 kg haL） of Azotobacter （a3） and medium dose （3.75 kg hal） of both Azospirillum （b2） and Phosphotica （c2） increased rhizome biomass by 6.8%-12.5% and shoot biomass by 5.6%-14.3% over other levels. They enhanced N, P and K removal by both rhizome and shoot when compared with other levels. The above biofertilizer treatments improved organic carbon and available N and P status of the soil by increasing N and P balance. The result showed overall strong negative K balance; but biofertilizer treatments greatly reduced the negative K balance in soil as compared to the control plots. Seed treatment with high level of Azotobacter along with medium level of Phosphotica （a3c2） produced the highest biomass yield （7.4 t hal）, increased N and P balance and fertility status in spite of hizh N, P and K removal.

Ginger yields in the NorthEastern region of India are low because the extremely poor farmers of the region can not afford to apply any chemical fertilizers and hence apply only the locally-available farmyard manures to ginger fields. Biofertilizers may be a cheap source of fertilizers for ginger cultivation as they can increase nutrient availability and improve rhizome quality and are required in small quantity. An investigation was thus undertaken to study the effect of different biofenilizers on growth, productivity, quality and economics of organic ginger grown under rainfed condition in NorthEastern region of India. Seed treatment with biofertilizers enhanced growth, increased rhizome yield by 19.0% and resulted in 32.4% higher net profit over control. Among the seed treatments, Azotobacter 5.0 kg ha＂l, Azospirillum 3.75 kg hal and Phosphotica 3.75 kg ha-1 were found optimum in improving most of the growth attributes, increasing yield components and yield of rhizome by 5.6%-13.5%. They also improved rhizome quality by increasing specific gravity, oleoresin and dry matter content and by decreasing crude fibre in rhizome. They resulted in higher net return by 4.0%-12.0% as compared to their other levels. Combined use of Azotobacter 5.0 kg hal along with Phosphotica 3.75 kg ha＂l was found to be the best treatment combination which greatly improved growth and yield attributes of ginger and ultimately recorded markedly higher productivity （2.0%-23.5%） over other combinations. This treatment combination improved the quality of the produce and resulted in the highest gross return （$4,905 hal）, net return （$3,525 hal） and return per dollar （3.55） invested in ginger cultivation. It appears that growing organic ginger by treating the seed rhizome with Azotobacter 5.0 kg ha-~ along with Phosphotica 3.75 kg ha-1 can result in good growth and high productivity of improved quality rhizome and ultimately result in maximum net profit and thus can be recommended for the NorthEas
