to study the effects of zabol wastewater treated with two kinds of fertilizer (manure and chemical fertilizer) application vs use of ordinary water on grain yield and yield components in corn (kosc704) a field experiment was conducted at the university of zabol, iran during 2007 growing season. the statistical plan selected was a split plot one of three replications. the treatments were compris...

northern regions of khuzestan province are suitable areas for soybean cultivation. hybridization blocks and soybean segregating generations were established in safiabad agricultural research center during 1990-1997 to produce new soybean lines which would have a high seed yield and high adaptability to the region. line l.14 selected from segregating generations of a hybridization between cultiv...

tillage and press wheel weight play an important role in seedling emergence, crop establishment and growth. an optimal combination of tillage implements and suitable press wheel weights should increase grain yield. this study investigated the effect of tillage systems and press wheel weights on dry land wheat (triticum aestivum l.) seedling emergence and grain yields in izeh, khuzestan province...

abstract soil crust decreases soil infiltration and prevents plant stablishment. thus reduction of crust effects is a prominent way to avert desertification. this study was conducted to investigate the effect of polyacrylamide on emergence of canola seedlings in a crusted soil and some physicochemical properties of soil such as ph, ec, sar and bulk density in a field located in date and tropica...

The interaction of the chaperonin GroEL14 with its cochaperonin GroES7 is dynamic, involving stable, asymmetric 1:1 complexes (GroES7.GroEL7-GroEL7) and transient, metastable symmetric 2:1 complexes [GroES7.GroEL7-GroEL7.GroES7]. The transient formation of a 2:1 complex permits exchange of free GroES7 for GroES7 bound in the stable 1:1 complex. Electrophoresis in the presence of ADP was used to...

line no. 4 was selected from local champ a rice of lord egan, based on pure line selection method, during 1992 to 1995. the mean yield of this line was 6342 and 6829 kgha-l in two regions of lord egan in 1996 to 1997. the yield of this line was 700-1500 kgha-l more than that of lord egan local rice. line 4 is more early maturing than the local rice with better marketability and quality. amylase...
