the increasing needs for energy, its high price and its environmental impact on greenhouse gases emission and limited energy resources due to increased research on energy balance in crop production systems. the objective of this research was to compare seedbed preparation and sowing methods in wheat production in kordkoy region with respect to energy use and efficiency. fifteen wheat fields wer...

Vigour was measured using computer-aided analysis of digital images in six seed lots of Impatiens that differed in vigour but retained greater than 86% standard germination. Seed lots that differed in initial seed vigour were selected based on the commercially used Ball Vigour Index and vigour independently assessed using saturated salts accelerated aging tests. Digital images were captured fro...

Preparation and Evaluation of Master seed prepared from Local variant infectious bronchitis virus (IBV) isolated from different poultry farms in Egypt and identified as IS/1494/06 nephropathogenic strain are very important point for vaccine production for controlling of infectious brobchitis(IB) disease in Egypt. Master seed of the virus (MSV) contained 10 EID50 per dose per bird free from bact...

this study was conducted during two years (2007-2009) in shawoor agricultural research station on a silty-clay soil. experiment conducted in split plots in a randomized complete blocks design in three replications. main plots were planting methods including centrifugal broadcaster (p1), centrifugal broadcaster + furrower (p2), seed drill (p3), seed drill + furrower (p4), three lines bed drillin...

Herein, we report a rapid route for the synthesis of AlPO4-5. By combining fast heating in a tubular reactor with a seed-assisted method, both of which were found to be crucial, the preparation of AlPO4-5 was completed in one minute, making this route the fastest known for the preparation of the crystalline microporous materials.
