Impact of integrated nutrient management on vegetative growth and flowering quality of gladiolus (Gladiolus hybridus Hort.) cv. American Beauty

A field study on ‘effects of integrated nutrient management on vegetative growth and flowering quality of gladiolus (Gladiolus hybridus Hort.) cv. American Beauty’ was carried out at College of Horticulture and Forestry, Jhalawar during 2016-17. It was found that cv. American Beauty with treatment the tallest plants (121.50 cm), maximum number of leaves per plant (9.03), the maximum  leaf length (38.20 cm), earliest spike emergence (59.22 days), minimum number of days to floret opening (12.50 days), maximum number of florets per spike (17.53), maximum spike length (108.50 cm), maximum floret diameter (9.01 cm), maximum rachis length (39.03 cm) was found in T12 (RDF 75% + Azotobacter + PSB + Mycorrhiza). The maximum stem diameter (1.52 cm) and maximum spike girth (0.97 cm) was recorded in T10 (RDF 75% + PSB + Mycorrhiza). On the basis of foregoing summary, the results may be concluded as follow: The different bio-fertilizer treatments had significant influence on the vegetative growth, flowering and post-harvest of gladiolus in the present study. Application of bio fertilizer singly and in different combinations has significant effect on all the vegetative, floral and corms parameters. Therefore, among various bio fertilizers and their combinations, Azotobacter, PSB and Myccorhiza were found the best, followed by un-inoculated treatment show least value for these parameters during the seasons of experiment

Кінетика сумісного виділення цинку і нікелю з розбавлених електролітів

Досліджені закономірності виділення цінку, нікелю і цинк-нікелевого сплаву з розведених електролітів, що містять в якості лігандів амінокислоту та аміак. Найкращі технологічні параметри та якість покрить отримані при спільному вмісті у розчині обох лігандів. Запропонований електроліт характеризується високою стабільністю, є технологічним та екологічно безпечним.The mechanisms of zinc, nickel and zinc-nickel alloy deposition from diluted electrolytes, containing amino acid or ammonia as a ligand, were investigated. The very technological characteristics and coatings quality were obtained if the electrolyte contained both of the ligands. The suggested electrolyte is characterized by high stability, processibility and it is ecologically safe

A SARS-CoV-2 protein interaction map reveals targets for drug repurposing

The novel coronavirus SARS-CoV-2, the causative agent of COVID-19 respiratory disease, has infected over 2.3 million people, killed over 160,000, and caused worldwide social and economic disruption1,2. There are currently no antiviral drugs with proven clinical efficacy, nor are there vaccines for its prevention, and these efforts are hampered by limited knowledge of the molecular details of SARS-CoV-2 infection. To address this, we cloned, tagged and expressed 26 of the 29 SARS-CoV-2 proteins in human cells and identified the human proteins physically associated with each using affinity-purification mass spectrometry (AP-MS), identifying 332 high-confidence SARS-CoV-2-human protein-protein interactions (PPIs). Among these, we identify 66 druggable human proteins or host factors targeted by 69 compounds (29 FDA-approved drugs, 12 drugs in clinical trials, and 28 preclinical compounds). Screening a subset of these in multiple viral assays identified two sets of pharmacological agents that displayed antiviral activity: inhibitors of mRNA translation and predicted regulators of the Sigma1 and Sigma2 receptors. Further studies of these host factor targeting agents, including their combination with drugs that directly target viral enzymes, could lead to a therapeutic regimen to treat COVID-19

Not AvailableVarious projections made to food requirement of human clearly indicates that the demands of animal products will increase in future, which call for augmenting the productivity of animal to meet the nutrition requirement of human population. The inadequate nutrition and deficit fodder has been reported as major constraint for sustainable animal production in the hot arid region. Therefore, augmenting the fodder availability is of prime concern. The present attempt is to highlight the important option s available to augment the fodder availability in arid region for the development of large-scale pastures and silvi-pasture systems.Not Availabl

Not AvailableAmong the perennial vegetation, shrubs are important as they cover 70-80 % of desert landscape from Aravalli to the international border of Indian part of Thar Desert. Shrubs have a vital role in sustenance of livelihood and ecological resilience of hot arid region. Despite their economic and ecological significances, indigenous shrubs did not get desired attention in research and development programme. Recently, focus has been shifted towards shrubs for emerging need of agricultural diversification, demand for fodder, medicinal and other economic products, along with their role in environment restoration. This chapter is an attempt to give comprehensive account of diversity and utilization of shrubs along with options for their conservation.Not Availabl

Not AvailableRangelands are important component of hot desert landscapes. They improve soil fertility, combat soil erosion, protect water tables, enhance water infiltration in soil and store carbon in soils mitigating climate change effects. Compared to arable farming, rangeland based animal husbandry has positive impacts on the desert environment and provide various ecosystem services and goods. Grazing based animal husbandry is not an economic activity in the desert but also an important component of cultural heritage. Although rangelands in hot arid region largely found in degraded state due to combination of environmental and socio-economic factors, they still remain the major forage resource base significantly contributing to the animal husbandry sector. Hot arid rangeland shrubs due to their morpho-physiological characteristics have very important role in climate change scenario. If, somehow, with available technologies and sound management these rangelands are brought back to their potential production level, the gap between forage supply and demand can be at least leveled up in view of climate change scenario.Not Availabl

Not AvailableHot arid region represents a range of diversity in native shrubs, which occur on a wide range of habitats. Some of these grow in extreme desertic habitat and survive in harsh climatic conditions. The diverse material of indigenous multipurpose little known shrubs offers a good scope for introduction in the farming system. This will be particularly useful on those areas where some of the species like Phog (Calligonum polygonoides), Lana (Haloxylon salicornicum), Gangeran (Grewia tenax), Kheep (Leptadenia pyrotechnica) etc make the dominant cover even in times of drought. These species with food and fuelwood value also provide the nutritious feed to animals during forage scarcity and drought period. Their introduction in suitable habitat will also help in conservation of these shrubs. In the chapter, importance and propagation of some of less known shrubs of western Rajasthan have been discussed.Not Availabl

Not AvailableIndigenous woody perennials are integral component of agricultural production system and have immense economic, ecological and social values in arid region. They provide variety of products that include food, fodder, fuel wood, gums, resins, fibre, medicine etc. they help to maintain ecological balance via preventing soil erosion, improving fertility of soil and promoting biodiversity. They possess peculiar structural, functional and biological characteristics, which allow them to survive in harsh climatic conditions. A number of perennial underutilized fruit species of arid region are used as human food in normal as well as in famine condition and play a vital role as life support species. The nutritional composition of these species indicates that these species could be important contributors to improving the nutrition and livelihood security of people of hot arid region.Not Availabl
