Response of Crop Production of Wheat (Triticum aestivum L.) to Use Different Level of Zinc Sulphate and Urea Fertilizer

Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Zinc plays an important role in protein metabolism, gene expression, structural and functional integrity of biological membranes and photosynthetic carbon metabolism. Indiscriminate use of chemical fertilizers to achieve high yield and to compensate for lack of nutrients and consequently the increase of production costs and destruction of soil and water resources have made the specialists interested in healthy and stable crop systems in terms of ecology.

This study was carried out to assess effect of different level of micro nutrient (Zinc) and macro nutrient (Nitrogen) on effective traits on wheat grain yield.

This research was done via factorial experiment based on randomized complete blocks design (RCBD) with three replications along 2016 year. The treatments included foliar application Zinc sulphate (Control, 3, 5 and 7 L.1000L-1 water) and Urea fertilizer (Control, 10, 20, 30 kg.ha-1).

According result of analysis of variance effect of Zinc sulphate, Urea fertilizer and interaction effect of treatments on all measured traits was significant (instead 1000 grain weight and harvest index). Evaluation mean comparison result of interaction effect of treatments indicated maximum number of grain per spike (30.58), number of spikelet per spike (17.39), grain yield (4547.78 kg.ha-1) and biological yield (13776.03 kg.ha-1) was noted for 7 L.1000L-1 water zinc sulphate and 30 kg.ha-1 Urea fertilizer and lowest ones belonged to control.

In general, according result of current research foliar application of urea (30 kg.ha-1) and zinc sulfate (7 L.1000L-1 water) can replace soil application to increase wheat production and can be advised to producers.
