on-farm experiments were designed to investigate the response of maize establishment and grain yield to variation in tillage systems. the tillage treatments included arara ploughing followed by zig-zag harrowing and arara ridging (t1); emcot ploughing fol-lowed by zig-zag harrowing and emcot ridging (t2); mouldboard ploughing followed by disc harrowing and mouldboard ridging (t3); disc ploughin...

today, the relationship between health-related quality of life at school (general satisfaction, relationships with teachers, negative emotions), body mass index with stress is challenging issues in domain of health and psychology. this study aimed to determine the perceived stress and its relationship with body mass index, general satisfaction, relationship with teachers, negative emotions. dur...

breeding for environmental stress is one of the most important goals in plant breeding. among stresses, drought stress has high influencing on limitation of wheat production. so, in order to find the best drought tolerant genotypes, 24 genotypes were planted in three separate experiments in ardebil: one with optimum irrigation (control), another with water stress at pre-anthesis stage and the o...

abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...

BACKGROUND Although cardiovascular (CV) risks are reported in first-degree relatives (FDRs) of type 2 diabetics, effects of gender on sympathovagal imbalance (SVI) and CV risks in these subjects have not been investigated. METHODS Body mass index (BMI), blood pressure variability parameters including baroreflex sensitivity (BRS), spectral indices of heart rate variability, autonomic function ...
