This Research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated Fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. Applied nutrients were zinc sulphate (Zn) of 0.0 and 1.5gl-1 and urea (N) at 0.0 and 5 gl-1 and Fe (1) control (low Fe)...

Pig manure (PM) is widely used as an organic fertilizer to increase yields of crops. Excessive application of compost containing relatively great concentrations of copper (Cu) and zinc (Zn) can change soil quality. To clarify the effects of different rates of application and to determine the optimal rate of fertilization, PM containing 1,115 mg Cu kg(-1), dry mass (dm) and 1,497 mg Zn kg(-1), d...

Zinc (Zn) deficiency constrains crop yield and quality, but soil factors influencing Zn availability to plants reactions of applied fertilizer are not fully understood. This work is aimed at studying in the use efficiency fertilizers by as affected properties particularly available P. We performed a pot experiment involving four consecutive crops fertilized with sulfate using 36 soils. The cumu...

Current malnourishment statistics are high and are exacerbated by contemporary agricultural practices that damage the very environments on which the production of nutritious food depends. As the World's population grows at an unprecedented rate, food systems must be revised to provide adequate nutrition while minimizing environmental impacts. One specific nutritional problem that needs attentio...

A field experiment using a block design was set up from 1995-1999. Soil at this site is the well-drained Bungor Series, clayey, kaolinitic, isohyperthermic Typic Paleudults. The treatments for the first cycle are no sludge application, inorganic N (ammonium sulfate) at 140 kg N ha and sludge application rates at 150, 300, 450 and 600% of recommended fertilizer N rate of 140 kg N ha. No sludge w...

A long-term experiment was conducted at research farm of department Soil Science, PAU to investigate the impact rice straw incorporation (0-10 t/ha/yr) and fertilizer N (0-150 kg N/ha) application on wheat yield Zn fractions after 7 years (2010–17). The treatments were arranged in a split plot design with three replications, (N0, N90, N120 N150) main plots (RS0, RS5, RS7. 5 RS10) sub-plots. Z...

This study was planned to estimate the performance of three zinc fertilizers [Zn sulfate heptahydrate (non-chelated), Zn- EDTA and Zn-humate (chelated)] at four levels (0, 2.5, 5.0, 7.5 mg kg-1) on use efficiency, availability crop productivity with rice. Field trials were conducted in clay loam sandy textured soils using factorial randomized block design (FRBD) replications. Data recorded yiel...

This study was carried out to determine the effects of nitrogen and zinc applied in different doses (0.0, 5.0, 10.0 15.0 kg N/da 0.0 2.5 ppm Zn) soil sample taken from Erzurum Atatürk University Faculty Agriculture Farm land on dry matter content mineral wheat maize. It under greenhouse conditions 96 pots (2 plants, 2 application methods, 4 doses, 3 replications). As a base fertilizer, it all b...

This research was conducted to evaluate the effect of soil application of nitrogen (N) and iron (Fe) fertilizers on morphological traits and shoot mineral contents of bread wheat via factorial arrangement based on randomized complete block design with four replications. The factors included three level of nitrogen (100, 200 and 400 mg N kg-1 dry soil applied) as Ca(NO3)2 and three rate of Iron ...
