BACKGROUND: Addition of fertilizers to supplement the natural soil fertility is essential for modern crop production, and precise management of nutrient elements is essential for a sustainable agriculture production.
OBJECTIVES: Current study was conducted to assessment effect of different level of micronutrient crop production and seed protein content of wheat.
METHODS: This research was carried out via factorial experiment based on randomized complete blocks design with three replications along 2018 year. The first factor included spray different level of Zinc (0, 2.5, 5 and 10 kg.ha-1) and second factor consisted spray Manganese at three level (0, 2 and 4 gr.1000L-1).
RESULT: Result of analysis of variance revealed effect of zinc and manganese on all measured traits (instead protein percentage) was significant also interaction effect of treatments on all measured traits (instead plant height, spike length and protein percentage) was significant. Mean comparison result of different level of zinc indicated the highest amount of plant height (89 cm), spike length (11cm), number of spike per square meter (403), number of seed per spike (42), 1000-seed weight (40gr), seed yield (5595 kg.ha-1), biologic yield (10364 kg.ha-1), harvest index (54%) and protein percentage (13%) was noted for 10 kg.ha-1 zinc fertilizer. Also compare different level of manganese and interaction effect of treatments showed similar result.
CONCLUSION: According result of current research the maximum amount of seed yield, its components, harvest index and protein percentage was belonged to consume spray 10 kg.ha-1 zinc and 4 gr.1000L-1 manganese fertilizer and it can be advised to producers.
