Abstract

In order to investigate the saffron yield and its components at different levels of corm size and plant density, an experiment was conducted at East Azerbaijan Agricultural and Natural resources Research Center, as a factorial based on randomized complete block design with three replications for two years (2012-2013).

Abstract

wheatReduction in herbicide usage without compromising yields can lead to less environmental harm and lower production costs. We evaluated the effects of both the plant population and reduced doses of sulfosulfuron plus metsulfuron-methyl on the weed infestation and crop performance of wheat. Results experiments revealed that a fairly acceptable level of weed suppression in wheat fields was achieved with lower doses of sulfosulfuron plus metsulfuron-methyl (30 g a.i. ha-1) in combination with plant density of 500 plant m-2 that were comparable to results with its label dose. Increased seeding rate was able to increased grain yield and number spike m-2. However, 1000-grain weight decreased with increasing seeding rate. The results suggested that weeds can be controlled in wheat, for a higher yield, when a reduced herbicide dose is used in combination with increasing seeding rate.

Key words: electrical conductivity, irrigation treatments, plant density, seed vigour.

Abstract:

A field experiment was conducted in 2012 to investigate the effects of different irrigation treatments and plant density on seed vigour of Dragon’s head (Lallemantia iberica Fish. et Mey.). The experiment was arranged as split plot based on randomized complete block design with four replications.
