To investigate the effect of polyethylene mulch, and manure on yield and yield components of cantaloupe, a two-year study (2007-2008) was carried out at Ardestan Agricultural Research Station by using split plot randomized based on complete block design with four replications. Three polyethylene mulch levels including clear polyethylene mulch, black polyethylene mulch and control treatment were...
Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...
Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...
Taxus baccata is a native species to the Caspian forests and is considered as the identification of these forests by some resources. The aim of this study was to understand the ecological characteristics of T. baccata in order to find suitable areas for its plantation in the Pone Aram preserve of Golestan province. Therefore, Multi-Criteria Evaluation (MCE) methods based on Analytical Hierarchy...
A field experiment was conducted to assess the effect of farmyard (cattle) manure (FYM) and inorganic nitrogen (N) phosphorus (P) fertilizers on growth and tuber yield of potato (Solanum tuberosum L.). The treatments consisted of factorial combination of 4 levels of FYM (0. 10, 20 and 30 t h-1) and three levels of inorganic NP fertilizers (0, 33.3%, 66.6% recommended rates) laid out in a Random...
in order to improve the efficiency of irrigation systems and investigate their impact on the pest population levels, furrow and sprinkler irrigation systems were compared in sugar beet fields. in this study, three different fields were chosen and irrigated by one of the furrow, classic and center pivot irrigation systems. in each field, 20 plots were randomly selected of which 10 plots were ma...
BACKGROUND Serum antibody responses in humans to inactivated influenza A (H5N1), (H9N2) and A (H7) vaccines have been varied but frequently low, particularly for subunit vaccines without adjuvant despite hemagglutinin (HA) concentrations expected to induce good responses. DESIGN To help understand the low responses to subunit vaccines, we evaluated influenza A (H5N1), (H9N2), (H7N7) vaccines ...
We present a technique for verifying the timing speci cations of the interfaces between digital systems. The veri cation process takes as input the timing protocols of each component as well as the connectivity between the components. The technique proceeds in three steps. First, a graph is built, which describes the causal relationships of events which can occur in the complete system. Second,...
The article shows for the first time results of studies on aftereffect 4 years a single use dairy industry waste - cake as fertilizer crops in crop rotation link: potatoes spring wheat barley productivity and product quality. In 2017, experimental plot after harvesting remains perennial grasses was mechanically processed with motor cultivator divided into plots 10 m2 following options: 1. Contr...
