In order to investigate the effects of sowing date on yield and some agronomic traits of six forage maize hybrids, two experiments were conducted in 2009 in two locations including Rasht and Fuman. The experimental design was randomized complete blocks with factorial arrangement and three replications. Treatments consisted of three levels of sowing date (31 May, 13 and 26 June) and six maize hy...

structure. So, it is possible to achieve the salinity-tolerant genotype in plants through creating changes in the genetic structure and breeding activities. Tomato is in the group of plants sensitive to salinity stress. Distinct studies have been explained different indicators for tolerance to salt stress in tomato. Identifying a reliable indicator in the early stages of plant growth under salt...

In order to assess the effects of different levels of nitrogen (N) and foliar application of iron amino chelate on yield and growth traits of dill medical plant, a factorial experiment was conducted in 2011 using a completely randomized design and three replications. In this experiment, five levels of N (0, 50, 100, 200 and 400 kg/ha N from urea source) and two levels of foliar spray of iron am...

Salinity and waterlogging are two important abiotic stresses to plants growth and yield in the world. These two stresses can occur simultaneously and have additive effects on plants, including corn, growth. In a greenhouse experiment, the effects of NaCl salinity and waterlogging and their interactive effect on the growth characteristics of forage corn (Zea mays cv. single cross 704) were studi...

To evaluate the effect of arbuscular mycorrhizal (AM) fungi (Glomus mosseae and Glomus intraradices) and Mesorhizobium Ciceri bacteria at three soil moisture levels [28% (field capacity, FC), 15% (-5 bar suction) and 9% (-10 bar tension) by weight] on morphological properties of root and aerial parts of chickpea, a greenhouse factorial experiment, arranged as a complete randomized design, was c...

To evaluate the effects of row spacing and plant density on yield and yield components of sweet corn, variety KSC403, an experiment was conducted in Research Farm of Isfahan University of Technology, Isfahan, Iran, in 2007, as randomized complete block design with a split-plot layout and three replications. The main plots were allocated to two row spacing (60 and 75 cm) and the sub-plots accomm...
