In order to study the efficacy of nicosulfuron in the control of redroot pigweed (Amaranthus retroflexus L.) using adjuvants, a greenhouse experiment was conducted at the Research Greenhouse, Faculty of Agriculture, University of Ferdowsi, Mashhad, Iran. The experiment was carried out as a factorial based on a randomized complete block design with four replications. Treatments included adjuvant...

Silicon (Si) is a beneficial nutrient for growth of crops such as cucumber. It seems that Si improves antioxidant capacity of plants and reduces damages induced by environmental stresses and metal toxicity. This research aimed to investigate the interaction of Si and cadmium (Cd) on growth, dry matter yield and catalase (CAT) activity, as an antioxidant enzyme, in cucumber. This hydroponic expe...

To investigate the effect of applying different amounts of municipal solid waste compost (MSWC) and sewage sludge (SS) on yield and concentration of some heavy metals including nickel (Ni), chromium (Cr), cadmium (Cd) and lead (Pb) in organs of green pepper plant, a pot experiment was conducted as a completely randomized design with seven treatments and four replications. Treatments included co...

Due to ever increasing greenhouse cultures, using organic fertilizers for enhancing healthy products is necessary. To investigate the effect of two types of these fertilizers on tomato, in a factorial experiment, based on completely randomized design with 3 replications, with 2 pots in each replication, 0 g/kg humic acid (Humic0) and 1 g/kg (Humic1) and amino acid at 3 levels of 0 g/kg (Amin0),...

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...

Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...

Plants deal with various stresses like salt stress in their life. Henbane is one of the important plants of potato family with numerous pharmaceutical effects. To assess the effects of salinity on growth responses of Henbane plant, experiment performed in growth chamber as pot culture based on a randomized complete design (CRD) with three replications. Seed germination percentage has been studi...
