Our understanding of the evolution of domestication has changed radically in the past 10 years, from a relatively simplistic rapid origin scenario to a protracted complex process in which plants adapted to the human environment. The adaptation of plants continued as the human environment changed with the expansion of agriculture from its centres of origin. Using archaeogenomics and computationa...

Environmental pollution poses a great health hazard to human beings, animals and plants. Pollution has also adverse effects on the land, water and its living and nonliving components. Industrial effluents, containing organic and inorganic compounds have strong influence on the development of growth of crop plants. When the concentration of the pollutants in the effluents are low, the agricultur...

Parallel declines in insect-pollinated plants and their pollinators have been reported as a result of agricultural intensification. Intensive arable plant communities have previously been shown to contain higher proportions of self-pollinated plants compared to natural or semi-natural plant communities. Though intensive grasslands are widespread, it is not known whether they show similar patter...

Nanotechnology monitors a leading agricultural controlling process, especially by its miniature dimension. Additionally, many potential benefits such as enhancement of food quality and safety, reduction of agricultural inputs, enrichment of absorbing nanoscale nutrients from the soil, etc. allow the application of nanotechnology to be resonant encumbrance. Agriculture, food, and natural resourc...

Devastating insect pests and environment-malignant pesticides that are applied against them are still a major problem in agriculture and horticulture. In plant breeding and genomic research there is an increasing demand for efficient screening methods of plants. In this study we develop a high-throughput phenotyping system to screen plants for resistance to aphids by video-tracking of insect be...

Weeds are currently present in a wide range of ecosystems worldwide. Although the beginning of their evolution is largely unknown, researchers assumed that they developed in tandem with cultivation since the appearance of agricultural habitats some 12,000 years ago. These rapidly-evolving plants invaded the human disturbed areas and thrived in the new habitat. Here we present unprecedented new ...

This paper details the automatic recognition of diseases & diseased component found in plants leaf picture & also in farming Crop creation. It is completed with development of technology which assists in farming to boom manufacturing. Primarily there's accuracy detection issue in current NN technique. In this research proposal, we have discussed the various advantages and disadvantage of the pl...

Arable areas are commonly susceptible to alien plant invasion because they experience dramatic environmental influences and intense anthropogenic activity. However, the limited reports on relevant factors in plant invasion of croplands have addressed single or a few invasive species and environmental factors. To elucidate key factors affecting plant invasions in croplands, we analyzed the relat...

1.Environmental changes may not always result in rapid changes in species distributions, abundances or diversity. In order to estimate the effects of, for example, land-use changes caused by agri-environment schemes (AES) on biodiversity and ecosystem services, information on the time-lag between the application of the scheme and the responses of organisms is essential.2.We examined the effects...

Foliar fertilization makes it possible to quickly supply plants with deficient nutrients, in case of both their deficiency the soil and hindered uptake. Crops are characterized by varying nutrient requirements for micronutrients, as well sensitivity deficiency. The paper presents practical aspects foliar feeding micronutrients using fertilizers, general classification characteristics. basic cro...
