Rice albumin from Oryza sativa (Var. Basmati 370) accounts for about 5% of the total seed proteins. A major fraction of rice albumin has been found to be a glycoprotein which is a monomer of 60 kd having iso-electric point 6.54. When rice albumin is digested with trypsin, it shows the presence of 24 peptides as against 28 peptides which were estimated from its amino acid composition. This indic...

Increasing population leads to intensification of water shortage problems in arid regions. Agriculture sector is the main user of water in Iran. Bushehr province with an arid and semiarid climate is located in the south of Iran. Improvement of water productivity (WP), the value or benefit derived from the use of water, is essential in the agriculture sector for achieving food security and susta...

There are scarce data connecting water relations in Azospirillum-inoculated wheat suffering drought during anthesis with the yield and mineral content of grains. Azospirillum brasilense Sp245-inoculated seeds of Triticum aestivum ‘Pro INTA Oasis’ were sown in nonirrigated and control plots. Water potential, water content, and relative water content were determined on flag leaves. Plant water st...

The effects of cultivar mixture cropping on yield, biomass, and water use efficiency (WUE) in winter wheat (Triticum aestivum L.) were investigated under non-irrigation (W0, no irrigation during growth stage), one time irrigation (W1, irrigation applied at stem elongation) and two times irrigation (W2, irrigation applied at stem elongation and anthesis) conditions. Nearly 90% of cultivar mixtur...

water and nitrogen fertilizer are two main factors of agricultural production and deficiency of each one makes reduction in the yield. deficit irrigation is one of the ways for water management in arid and semiarid areas, but it is effective on the need of nitrogen. excessive use of nitrogen will be a waste of capital and environmental pollution. in this study the interaction of water and nitro...

Nitrogen (N) is a nutrient element necessary for plant growth and development. However, excessive inputs of N will lead to inefficient use and large N losses to the environment, which can adversely affect air and water quality, biodiversity and human health. To examine the effects of controlled-release fertilisers (CRF) on yield, we measured ammonia volatilisation, N use efficiency (NUE) and ph...
