Non-point source pollution is considered as a serious issue especially in the field of eutrophication for surface waters. Vegetative buffer strips include a specific plant being passed by flow before entering the waterways, so it causes to reduce runoff volume, deposited pesticides and other pollutants of the flow through infiltration, absorption and sediment deposition. The present study has b...
Agriculture in the context of climate arrives at a favorable outcome. One of the important goals in agricultural researches is the investigation of effects of atmospheric parameter on various agricultural products. In this research we study the thermal and phenological conditions of grape cultivation in Hamadan province. In this study we analyzed thermal conditions for grape based on minimum an...
Among the natural enemies of insect pests in rice fields, parasitoids are especially notable. To better understand the space-time dynamics of these insects, the objectives of this study were to describe and compare groups of parasitoids in organic irrigated rice fields using two management approaches for levee vegetation, and to relate them to the phenological stages of rice cultivation (the se...
Article info: Received: 27 August 2014 Accepted: 13 November 2014 ABSTRACT Root biomass accumulation in spring and winter varieties and hybrids pea was recorded in field experiment in the Institute of Forage Crops, Pleven, Bulgaria (2011-2013). Spring (Shtambovyi and Pleven 4) and winter (Rosacrono and Pleven 10) varieties and their hybrids (Shtambovyi x Pleven 10 and Rosacrono х Pleven 4) (in ...
Phenology is a key aspect of plant success. Recent research has demonstrated that herbarium specimens can provide important information on plant phenology. Massive digitization efforts have the potential to greatly expand herbarium-based phenological research, but also pose a serious challenge regarding efficient data collection. Here, we introduce CrowdCurio, a crowdsourcing tool for the colle...
Phenology offers critical insights into the responses of species to climate change; shifts in species' phenologies can result in disruptions to the ecosystem processes and services upon which human livelihood depends. To better detect such shifts, scientists need long-term phenological records covering many taxa and across a broad geographic distribution. To date, phenological observation effor...
