Assessment Effect of Spray Different level of Zinc and Magnesium on Crop Production and Agrophysiological Characteristics of Wheat

BACKGROUND: Suitable and useful usage of different kind of fertilizers is the main way for reformation and potential of soil fertility and increasing of crops yield. Microelements are the critical elements for plants; also play the important role in crop productivity where it is used in low rate. Optimum plant nutrition and maximum yield is achieved when nutrient elements are available for plant during the growing season. OBJECTIVES: This research was carried out to evaluate response of seed yield, materials redistribution and current photosynthesis of wheat under apply different level of microelements (Zinc and Manganese). METHODS: Current study was conducted according 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: Evaluation of analysis of variance indicated effect of different level of zinc on all measured traits was significant, also effect different level of Manganese (instead contribution and efficiency of redistribution) and interaction effect of treatments (instead efficiency of current photosynthesis) on all measured traits had similar result. Mean comparison result of different level of zinc revealed the maximum amount of seed yield (5258 kg.ha-1), rate of redistribution (150.2 gr.m-2), contribution of redistribution (28.5%), efficiency of redistribution (12.6 gr.gr-1), rate of current photosynthesis (375 gr.m-2), efficiency of current photosynthesis (48.5%) was noted for 10 kg.ha-1 zinc fertilizer. Also compare different level of manganese and interaction effect of treatments showed similar result. CONCLUSION: Finally according result of current study the highest of amount of crop production and agrophysiological traits belonged to spray 10 kg.ha-1 zinc and 4 gr.1000L-1 manganese micronutrient and under studied region it can be advised to farmers.
