in this study 18 corn hybrids consist of 15 new early and mid mature foreign hybrids and three commercial iranian corn hybrids (ksc704, ksc647 and dc370) as controls were evaluated at two rcbd with three replications at the khorasan razavi agricultural research and natural resources center, during 2008 -2010. results showed that hybrid exp1 and dc370 with 16.5 and 12.1 t.ha-1 were the best and ...

The thermal conversion of sewage sludge to biochar offers a promising alternative use for a hazardous waste material with potential benefits to agricultural productivity and soil quality. Three short-term greenhouse experiments were conducted to evaluate the effect of corn cob (CC) and sewage sludge (SS) biochars, with their anaerobically treated counterparts, on soil properties and plant growt...

Nutrient composition of individual feed ingredient in mixed feed is important for accurate formulation of animal feeds. However, each feed ingredient can be different depending on its origin. Therefore, this study was conducted to investigate the variability in nutrient compositions of corn, wheat, and barley grains from different origins. Cereal grains used in this study were from 5 countries ...

The enzyme PAD from Lactobacillus plantarum CECT 748T decarboxylates some cinnamic acids namely p-coumaric acid (p-CA), caffeic acid (CA), and ferulic acid (FA) into their corresponding 4-vinyl derivatives (4-VD): 4-vinyl phenol (4-VP), 4-vinyl catechol (4-VC), and 4-vinyl guaiacol (4-VG), respectively, which are valuable food additives mainly employed as flavouring agents. The gene encoding th...

Ustilago maydis is the causative agent of common smut of corn. Early studies noted its ability to synthesize phytohormones and, more recently these growth promoting substances were confirmed as cytokinins (CKs). Cytokinins comprise a group of phytohormones commonly associated with actively dividing tissues. Lab analyses identified variation in virulence between U. maydis dikaryon and solopathog...

this experiment was carried out at agricultural research station of gorgan during summer 2006 to study the effects of corn and green gram intercropping on forage yield, and weed biomass. the experimental design was rcbd with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops employed. the experimental treatments consisted of sole corn and sole g...
