A field experiment was conducted to evaluate the effect of planting pattern and irrigation system on antioxidant activity of wheat and Persian clover. The experiment was carried out as a two-factor factorial with three replications. The first factor was irrigation system (conventional and partial root-zone irrigation) and the second was planting pattern (sole wheat, sole Persian clover, alterna...

The effects of plant density and water stress on yield of Medicago sativa and Bromus tomentellus was studied. A greenhouse experiment was conducted at Isfahan University of Technology in 2013. The experiment included 18 treatments, three crop compositions (M.sativa, B. tomentellus or mixture of the two), two plant density levels, three watering regimes and four replicates, arranged in a complet...

A global atmospheric general circulation model (GCM) is modified to include radiative transfer parameterizations for the absorption and scattering of solar radiation and the absorption of thermal infrared (IR} radiation by smoke aerosols. The solar scattering modifications include a parameterization for diagnosing smoke optical properties as a function of the timeand spacedependent smoke partic...

Land policy in India has been under discussion even prior to independence and especially following the infamous Deccan Riots. One of the important issues on which the peasants backed the independence movement was the land to the tiller policy promised by the then Congress party. Immediately after the independence a Committee under the Chairmanship of Late Shri J C Kumarappa (A senior Congress l...

Phosphorus (P) losses from land-applied manure can contribute to nonpoint source pollution of surface waters. Dietary P levels influence P concentrations in animal manures and may affect P losses from land-applied manure. The objective of this study was to determine the effects of dairy diet P concentration on P losses in runoff from landapplied manure. Manures with P concentrations of 0.48 and...
