Evaluation Effect of Macro and Micro Nutritional Elements on Quantitative and Qualitative Characteristics of Oat Crop (Avena sativa L.)

In order to assessment the effect of micro and macro nutrients on agro physiological traits of oat crop a research was conducted via split plot experiment based on randomized complete block design with three replications at Agricultural Research Station, Faculty of Agriculture, Shahid Chamran University of Ahvaz, along 2013-2014. The main factor included different complex of macro and micro nutrient elements at two level [F1: application 114 kg.ha-1 nitrogen from 46% source of urea, application 16.8 kg.ha-1 phosphorus from the source of super phosphate, 29.1 kg.ha-1 potassium from the source of potassium sulfate; F2: application of macro elements (N, P, K) along with a mixture of micro elements contain 0.8 kg.ha-1 iron, 0.88 kg.ha-1 zinc, molybdenum 0.1 kg.ha-1, copper 0.2 kg.ha-1, boron 0.1 kg.ha-1 and manganese 2.0 kg.ha-1]. Sub-factor consisted of four genotypes (G1, G2, G3 and G4) of oat crop. According result of analysis of variance effect of different fertilizer management, genotypes and interaction effect of treatments on all measured traits (instead ash concentration) was significant at 1% probability level. Assessment mean comparison result of interaction effect of treatments showed maximum amount of all measured traits (instead ash concentration) concentration was noted for F2G3 and lowest one belonged to F1G2 treatment, it could be concluded F2G3 treatment has positive effect on all the characteristics under study and increases the seed yield.
