RESUMO
It is important for the breeders to find how genetic differences may affect crop grain yield and nutrient uptake affected by micronutrient fertilization. Accordingly, with respect to our published research, the foliar application of the most deficient micronutrients (Fe, Zn and Mn) in the arid and semi-arid areas of the world affecting grain yield and nutrient concentration of maize parental lines of new hybrid genotypes was tested in a two-year experiment (2016-2017). A split plot experiment (randomized complete block design) with seven maize parental lines (G1-G7, sub-plots), and eight micronutrients treatments (main plots) including control (without spraying, M1), Zn (M2), Mn (M3), and Fe (M4) at 3 g L-1, Mn + Zn (M5), Fe + Zn (M6), Fe + Mn (M7), and Fe + Mn + Zn (M8) at 1.5 g L-1, sprayed at the growth stages of V8 and the full appearance of the plant organs (R1) was conducted. Plant height, cob height, 1000 grain weight, grain yield, number of rows per cob, number of grains per row, grain crude protein content, and micronutrient (Zn, Fe and Mn) concentrations were determined. Micronutrients significantly affected Fe (27.68-62.55 mg. kg-1) and Zn (33.34-55.73 mg. kg-1) concentrations. A3 (12,600 kg. ha-1) and A5 (8900 kg. ha-1) resulted in the highest and least grain yield, respectively. M7 (11,470 kg. ha-1) had the highest grain yield significantly different from control (5510 kg. ha-1). Interestingly, just Mn significantly affected grain crude protein (9.63-12.92%). Correlation coefficients indicated Mn and Fe as the least and the most correlated micronutrients with the growth of maize parental lines.

RESUMO
INTRODUCTION: A brief neuroscience-informed psychoeducation program (Neuroscience-Informed Psychoeducation for Recovery [NIPER]) was developed to promote awareness (metacognition) in the main cognitive domains affected by drug and alcohol use to increase willingness to invest time and effort in the brain and cognition recovery process. The primary aim of this pilot study was to determine the feasibility and acceptability of the NIPER program and its potential effectiveness in increasing metacognition, psychological wellbeing, and willingness for the brain and cognition recovery programs among patients with Substance Use Disorders (SUDs). METHODS: A total of 56 patients with SUDs were recruited from four outpatient treatment centers in Tehran City, Iran. They participated in four 90-min weekly sessions delivered adjunct to their routine treatment. The program's effectiveness was measured in terms of metacognition and psychological wellbeing at baseline and the end of the program. The rate of adherence and participation and willingness to continue with brain and cognition recovery programs were measured as feasibility outcomes. RESULTS: A total of 51 participants completed the study. Compared to the baseline assessments, patients reported more problems in dimensions of attention, memory, inhibitory control, decision making, motor/speech, interoception, insight, and a higher level of psychological wellbeing (t=4.66; P<0.001). In terms of feasibility outcomes, the adherence and participation rates were found above 85%. Most participants expressed their high willingness to continue the brain and cognition recovery programs (86.2%) and would introduce NIPER to their peers (98%). CONCLUSION: Considering the pilot results in terms of feasibility and preliminary effectiveness of NIPER in the clinical context of addiction treatment, we think that NIPER is a potentially beneficial intervention to be offered to people with SUD. It would increase their awareness and engage them in the brain and cognition recovery process. However, the clinical efficacy of the intervention should be tested in future randomized clinical trials.
