A pot culture experiment was conducted to study the effect of soil amendment with different forms groundnut waste on spore population and root infection indigenous Arbuscular Mycorrhizal fungal species i.e. Glomus mosseae under polyhouse conditions. Two angiospermic plant viz. sorghum sesame were also examined for mycorrhization potential in study. Observations made percent colonization, densit...

  Abstract Two experiments with factorial arrangements on the basis of randomized complete block design in three replications were conducted in 2007 and 2008, to evaluate chlorophyll content index (CCI), fluorescence of chlorophyll, proline content and grain yield of three soybean cultivars (Williams, Zan and L17) under a non-saline (control) and three saline (3, 6 and 9 ds/m NaCl) conditions...

screening methods that are effective in the early stage of growth will potentially provide the largest quantity of breeding material. although various screening methods under greenhouse have been proposed, potential effective approaches must be described a good correlation with results under field conditions. this study was aimed to assess the correlations between traits obtained from four salt...

Soil organisms influence plant species coexistence and invasion potential. Plant-soil feedbacks occur when plants change soil community composition such that interactions with that soil community in turn may positively or negatively affect the performance of conspecifics. Theories predict and studies show that invasions may be promoted by stronger negative soil feedbacks for native compared wit...

At present, there is limited understanding of how biochar application to soil could be beneficial to crop growth in temperate regions and which biochar types are most suitable. Biochar’s (two feedstocks: willow, pine; three pyrolysis temperatures: 450 °C, 550 °C, 650 °C) effect on nitrogen (N) availability, N use efficiency and crop yield was studied in northwestern European soils using a combi...

in order to study the effects of drought stress and municipal compost on quantitive characteristics in peppermint , a green house experiment in a factorial based on a randomized complete block design with four replications was conducted in 2009 at university of zabol. treatments included: three irrigation levels %100 field capacity(control),%80 field capacity(mild stress) and %60 field capacity...

build, maintain the body's structure and supply energy for vital activities. Protein tends to be the most expensive. The safest, simplest and cheapest source is the non protein nitrogen urea. It has been reported that one hundred grammes of urea are equivalent to 200g of digestible protein provided the remainder of the ration supplies enough readily usable energy (McDonald et al., 1995). The ce...
