For over two centuries homeopathy has demonstrated its therapeutic properties, thus gaining more and more supporters worldwide. Many researchers opine that due to absence of a medicinal substance in a homeopathic preparation it is not necessary to study its healing effect. However, for the last few years our research was focused not only on understanding the mechanism(s) of homeopathic action in medical and veterinary practices but also on the effect of different homeopathic preparations on plants. The studies aimed to rule out the placebo effect from the homeopathic phenomenon, but also at identification of therapeutic effect on different plants. These studies allowed to extend the boundaries of practical use of homeopathy including its common use in the farming industry. The efficacy of various homeopathic preparations was assessed for their use in plant growth through application techniques such as watering, spraying, soaking and sprinkling etc. Growth dynamics, duration of fruit ripening, crop yield were monitored and compared to reference plants. Homeopathic preparations for agricultural plants were carefully selected on the basis of their effect on the crop yield – the principal criterion for the selection. Based on these criteria it was observed that the homeopathic picture of tomatoes, cucumbers, potatoes is almost same within one variety, in all tested sorts, although, in case of fruit trees such as apple, pear the homeopathic similimum varied depending of the selection method. Our results showed that, in case of trees, one-time application of homeopathic preparation during a season is preferable and sufficient. In case of vegetable cultures, application may not be more frequent than once a month as more frequent application results in diminishing of yield. For root plants single treatment at the time of planting was sufficient. The performed studies showed that the growth and ripening indicators significantly prevailed in the vegetables, which had been treated with homeopathic preparations, as compared to common traditional way of plant handling (controls). Thus the performed studies suggest the following: a) Homeopathic effect on biological structures is not a placebo effect. b) Obtained data are a categorical proof of the homeopathic preparation effect on plants causing higher yield in agricultural crops and therefore, have good potential for their use on the industrial scale in agriculture. c) The potential of the homeopathic phenomenon practical use has not been fully explored yet and needs a follow-up study.

Methanol is abundant in the phyllosphere, the surface of the above-ground parts of plants, and its concentration oscillates diurnally. The phyllosphere is one of the major habitats for a group of microorganisms, the so-called methylotrophs, that utilize one-carbon (C1) compounds, such as methanol and methane, as their sole source of carbon and energy. Among phyllospheric microorganisms, methanol-utilizing methylotrophic bacteria, known as pink-pigmented facultative methylotrophs (PPFMs), are the dominant colonizers of the phyllosphere, and some of them have recently been shown to have the ability to promote plant growth and increase crop yield. In addition to PPFMs, methanol-utilizing yeasts can proliferate and survive in the phyllosphere by using unique molecular and cellular mechanisms to adapt to the stressful phyllosphere environment. This review describes our current understanding of the physiology of methylotrophic bacteria and yeasts living in the phyllosphere where they are exposed to diurnal cycles of environmental conditions.

Environmental adversities, particularly drought and nutrient limitation, are among the major causes of crop losses worldwide. Due to the rapid increase of the world’s population, there is an urgent need to combine knowledge of plant science with innovative applications in agriculture to protect plant growth and thus enhance crop yield. In recent decades, engineering strategies have been successfully developed with the aim to improve growth and stress tolerance in plants. Most strategies applied so far have relied on transgenic approaches and/or chemical treatments. However, to cope with rapid climate change and the need to secure sustainable agriculture and biomass production, innovative approaches need to be developed to effectively meet these challenges and demands. In this review, we summarize recent and advanced strategies that involve the use of plant-related cyanobacterial proteins, macro- and micronutrient management, nutrient-coated nanoparticles, and phytopathogenic organisms, all of which offer promise as protective resources to shield plants from climate challenges and to boost stress tolerance in crops.

In the present era, the global need for food is increasing rapidly; nanomaterials are a useful tool for improving crop production and yield. The application of nanomaterials can improve plant growth parameters. Biotic stress is induced by many microbes in crops and causes disease and high yield loss. Every year, approximately 20–40% of crop yield is lost due to plant diseases caused by various pests and pathogens. Current plant disease or biotic stress management mainly relies on toxic fungicides and pesticides that are potentially harmful to the environment. Nanotechnology emerged as an alternative for the sustainable and eco-friendly management of biotic stress induced by pests and pathogens on crops. In this review article, we assess the role and impact of different nanoparticles in plant disease management, and this review explores the direction in which nanoparticles can be utilized for improving plant growth and crop yield.

Abstract There is no consensus for the management of incidental meningiomas. To evaluate the natural history, we assessed tumour growth dynamics during 10 years of active monitoring of 62 patients (45 female and mean age 63.9) harbouring 68 tumours. Radiological and clinical data was obtained was obtained biannually for two years, then annually the following eight. Thirty-six patients (38 tumours) were referred to treatment and/or died of unrelated causes (n=5) within 5 years. The remaining were monitored for up to 10 years. Mean overall survival was at 128 months (95% CI: 118.8-136.7). Median progression free survival was 34 months (95% CI: 14.7-53.3). Median time for growth requiring intervention was 46 months (95% CI: 23.5-68.5). All tumours with self-limiting growth at 5 years (57.9 %) were still stable or reducing in size at 10 years. Mean growth rate decreased from 0.27 cm3/year (95% CI: 0.10-0.43) during the early observation period (0-5 years) to 0.09 cm3/year (95% CI: -0.02-0.21) in the late observation period. No tumours were referred to treatment during the late observation period. Two patients, both with verified WHO2 grade meningiomas succumbed to the disease, seven and eight years after diagnosis. No other patients developed symptoms and none other of the 18 total mortalities were meningioma related. Most clinical and radiological events occur within 5 years after diagnosis. Our findings suggests that if tumour growth slows down during the first 5 years of monitoring, this trend will continue. Clinical follow-up should be sufficient when a self-limiting growth pattern has been established.

Food security is one of the major concerns for all developing countries of the world. Even though we had attained the highest food production with the use of new technologies, we may not able to feed the burgeoning population adequately in coming years due to stagnant crop productivity. Natural source of nutrients like organic manures and external source of nutrients, viz. fertilizers, are considered as the two eyes in plant nutrient management. Nutrient use efficiency of fertilizer is very low due to numerous pathways of losses such as leaching, denitrification, microbial immobilization, fixation and runoff. It has been estimated that around 40-70% of nitrogen, 80-90% of phosphorus, 50-70% of potassium and more than 95% of micronutrient content of applied fertilizers are lost in to the environment and results in pollution (Kanjana, 2017). Smart fertilizers like slow and controlled release fertilizers, nanofertilizers and bioformulation fertilizers are the new technologies to enhance the nutrient use efficiency their by improving crop yield in sustainable manner. The use of slow and controlled release fertilizers increase nutrient use efficiency, minimize the risks like leaf burning, water contamination and eutrophication. Nano-fertilizers are the nano-particles-based fertilizers, where supply of the nutrients is made precisely for maximum plant growth, have higher use efficiency, exploiting plant unavailable nutrients in the rhizosphere and can be delivered on real time basis into the rhizosphere or by foliar spray (Priyanka Solangi et al., 2015). The small size, high specific surface area and reactivity of nano fertilizers increase the solubility, diffusion and availability of nutrients to plants and enhance crop productivity. Bioformulation is microbial preparations containing specific beneficial microorganisms which are capable of fixing or solubilizing or mobilizing plant nutrients for promoting plant growth and crop yield. Smart fertilizers are the better option for the farmers to increase their crop yield with low input cost in sustainable way without degrading natural environment.
