Gold nanoparticles which are known for thousands years started their progress in 19 century. Nowadays gold nanoparticles are used in several fields of chemistry, physics, materials, medicine, and optics due to their unique physical and chemical properties (ref. 1). However, their applications in the separation science are still relatively rare. Nanoparticles have been successfully used to enhan...

There is an increasing market for locally grown malting barley (Hordeum vulgare L.) in the Northeast US. Malting must meet certain quality standards acceptability brewing market. Up-to-date recommendations are needed regionally adaptation to ongoing climate change. A two-year field experiment was conducted assess interactive influence of three dates planting (5 September, 15 and 25 September), ...

Determining the best combinations of variety choice and planting date may be crucial for farmers in view of optimising bean yields. A study was conducted to assess the agronomic performance of selected dry bean (Phaseolus vulgaris L.) lines when planted sequentially under rain fed conditions in the Western Highlands of Cameroon (WHC). Forty two introduced lines and three local checks were used,...

Abstract In the Peruvian Andes, first light rainfalls towards end of dry season in August-September are known as pushpa . Softening soils and improving sowing conditions, these rains crucial for planting dates agricultural planning. Yet remains to date unexplored literature. This study uses observations convection-permitting model simulations describe characteristics Rio Santa valley (Peru). Co...

The sensitivity of soybean [Glycine max (L.) Merr.] main stem node accrual to ambient temperature has been documented in greenhousegrown plants but not with fi eld-grown plants in the north-central United States. Biweekly V-node and R-stage, stem node number, internode length, and other traits were quantifi ed in an irrigated split-plot, four-replicate, randomized complete block experiment cond...

A field trial was conducted at the research farm of RRL, Jorhat during 1995 and 1996 to study the performance of Mentha Piperita under varying dates of planting and row spacings, maximum herbage and oil yield were obtained from January plants crops. Yield deceased when planting was delayed planting at a closer row spacing of 45 cm recorded the maximum herbage yield of 61'92 q/a while the yield ...

in order to investigate the effect of high density and depth of planting on agronomic characteristic of saffron, a field experiment was conducted as a complete randomized block design with three replications in faculty of agriculture, ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments were six levels of high densities (8, 11, 13, 16, 19 and 21...

The use of water resources should be restricted until a suitable irrigation and planting system is developed in the North China Plain. This study was aimed to study the effects of planting pattern and irrigation on the farmland microclimate, and indentify possible ways to improve the yield of winter wheat. The field experiments in a randomized complete block design with four replicates were con...
