“…Explanations for Zn deficiency have included increased growth rate with marginal supply of Zn; change in soil solution pH due to different nitrogen source; Zn retention in the roots as a NÁZn protein complex (Ozanne, 1955). More recently evidence of a nitrogen/zinc interaction has been forthcoming from the observation that continuous use of highanalysis nitrogenous fertilizers and intensive cultivation of high-yielding crop varieties is associated with widespread Zn deficiency on a variety of soils (Verma & Bhagat, 1990). The same authors have also observed that the uptake of Zn by wheat on an acid soil was increased by nitrogen supplied as urea regardless of whether the soil was limed or not.…”

Due to continuous single nitrogen fertilization, we hypothesized a built-up deficiency of micronutrients in crops that would limit plant growth and crop quality. In 2-year field experiments using urea-N fertilized grain maize (Zea mays L.), hybrid KWS 2376 at 0, 120 and 240 kg N ha (1 crop uptake of Zn, Mn, Cu and Fe was studied at DC 32, DC 61 and in the grain harvested. Micronutrient contents at DC 32 stage Á 1st node (aboveground phytomass) and DC 61 Á flowering (ear leaf) were all at levels indicative of adequate micronutrient supply to the crop. At both sampling occasions the Fe:Zn and Fe:Mn ratios were adequate implying that Fe did not inhibit the uptake of Zn and Mn. The application of nitrogen increased the Fe content at the 1st sampling in both years; in the second year the same was also the case for the Zn content. Nitrogen nutrition increased the contents of Mn and Fe at the 2nd sampling only in year 2; in the other treatments no changes were observed in the micronutrient contents. Micronutrient correlations in the grain were discovered between Zn and Mn contents and between Fe and Mn contents. In the second year the highest N-rate significantly increased the Fe and Zn content of the grain compared with the lower rates of nitrogen fertilization. Grain yields were not affected by the rate of nitrogen and ranged between 13.65 and 14.34 t ha (1 (1st year) and between 13.68 and 14.18 t ha (1 (2nd year). Nitrogen fertilization did not reduce the content of micronutrients in the plant or grain of maize. It is evident that the continuous single use of N fertilization so far has not resulted in a micronutrient deficiency of the plants limiting the nutrient density of the grain or reducing its quality.

“…N treatment has been determined to effect Zn absorption by plants and vice versa. N x Zn interaction is an important factor in nutrient management for all field crops that require moderate to high amounts of N. The synergistic N x Zn interaction has also been determined to increase the N concentration in different crops as Zn helps to accelerate protein synthesis and the biological N 2 fixation (Verma and Bhagat, 1990). Zn uptake of soil solution is generally in divalent cation form (Zn 2+ ), but in calcareous soils with high pH zinc uptake may be in valence ion form.…”

Plant density for poppy (Papaver Somniferum L.) and impacts of genotype and nitrogen fertilizer dose applications on total ash, N, P, K, Ca, Mg, Na, Fe, Mn, Zn, Cu contents on poppy leaves, capsule yield, seed yield and morphine ratio were investigated. Two plant density (SD 1 : 25 plants per m 2 , SD 2 : 16 plants per m 2 ), four poppy genotypes (Zaferyolu, Tınaztepe, Ofis 3 and Local line) and four nitrogen fertilizer dose (0, 6, 12 and 18 kg da -1 ) were used. Experiments were conducted in randomized complete block, split-split plots design with 3 replications for 2 years (2009/10 and 2010/11). While the effect of plant density x nitrogen dose x genotype interaction was statistically significant in terms of the total ash (p<0.01), mineral elements of poppy leaves, capsule yield and seed yield, it was not significant for morphine ratio. The highest capsule yield and seed yield (134.30 kg da -1 and 161.11 kg da -1 ) were obtained in 12 kg da -1 N treatment of local line genotype at SD 1 plant density and the lowest capsule yield and seed yield (67.22 kg da -1 and 76.53 kg da -1 ) were observed in the without nitrogen of Tınaztepe genotype at SD 2 plant density, respectively. Morphine ratios were determined as 0.445%, 0.508%, 0.570% and 0.597% according to N doses (0, 6, 12 ve 18 kg da -1 ), respectively. With regard to plant density, SD 1 (25 plants per m 2 ) was prominent for majority of investigated parameters. As compared to other genotypes, Ofis 3 genotype can be recommended 12 kg da -1 N treatment in terms of mineral nutrient contents of poppy leaves and morphine ratio at SD 1 plant density.

“…But, use of organics alone does not result in spectacular increase in crop yields, due to their low nutrient status. Sustainable yield could be achieved only by applying appropriate combination of green manures or organic manures and chemical fertilizers (Verma and Bhagat, 1990;Obi and Ebo, 1995). Farmyard manure (FYM) is also considered as an important source of macro and micronutrients to increase crop yield.…”

A field experiment was conducted during 201112 and 201213 at New Delhi, to evaluate the effect of inte- grated nutrient management on growth and yield attributes, yield and economics of maize (Zea mays L.)wheat {Triticum aestivum (L.) emend. Fiori & Paol.} cropping system. The experiment was laid out in a randomized block design (RBD) during the first year of maize and in factorial randomized block design (FRBD) in successive crops with 3 replications, consisting of 5 different treatments in rainy and winter season each comprising 25 treatment combinations. The results revealed that 50% recommended dose of fertilizer (RDF-120 kg N, 60 kg P O and 40 2 5 kg K O/ha) + 50% recommended dose of nitrogen (RDN-120 kg N/ha) through crop residue mixed farmyard ma- 2 nure resulted in significantly higher maize grain yield (4.24 t/ha) over the control (2.23 t/ha) during first year, but during the second year (5.25 t/ha) it was significantly higher than the control (3.07 t/ha) and 50% RDF + 25% RDN + biofertilizer (4.83 t/ha). Application of 100% RDF to maize recorded significantly maximum net profit ( 28.22 103, 42.74 103 /ha), followed by 75% RDF + 25% RDN. However, benefit: cost (B:C) ratio of 1.33 and 1.60 were recorded significantly higher under the control over the other treatments followed by 100% RDF, during 2011 and 2012 respectively. In wheat crop, 100% RDF showed significantly higher growth and yield attributes over the control. The maximum wheat grain yield (4.97 t/ha) and net returns (66.96 103) were recorded with the applica- tion of 100% RDF through chemical fertilizers, whereas, maximum B: C ratio (2.76) was recorded in control.
