Abstract

In order to investigate the phenological and morphological traits of Arachis hypogeae L., influenced by row spacing and iron and zinc micronutrients in Moghan conditions, an experiment was conducted in Ardabil province, 15 km in Parsabad, Jafarabad, Mahmoodabad village, Taleghani region Moghan was a factorial based on randomized complete block design with three replications. The cultivar used in this study was the plant type and dominant type of the region called NC2 or North Carolina 2. The factors used were: the spacing between rows of three levels, 75, 60 and 45 cm, and the iron and zinc micronutrient foliar application in four levels, without micronutrients, iron in the amount of 3.5 grams per liter, zinc to the amount 1.5 grams per liter, and iron and zinc micronutrients mixed together and in the same amount in three stages of peanut growth stages (20, 35 and 50 days after germination). The results of analysis of variance and means comparisons showed that phenological traits were not significant for row spacing treatments, but the other studied traits for this treatment and spraying treatment were significant for all traits at 1% probability level. For interactions of these treatments, plant height and shoot dry weight were significant at 5% probability and 1%, respectively, and the other traits were non-significant. Increasing the plant density increased altitude, but in shoot dry weight and grain yield, the reverse was used. Also, the fourth treatment had the highest amount and in some of the traits it was in the second group with the second level of spraying. As a result, with the conditions of this experiment, the spacing of 60 cm row spacing with combination of iron and zinc could be the best treatment.
