Nutrient distribution across wheat rhizosphere with oxamide and ammonium sulfate as N source

Abstract: Analysis of the behavior of slow releasing nitrogen fertilizers in the rhizosphere soil of agricultural crops is essential for their effective use. This work presents a comparative study of the effects of oxamide and ammonium sulfate as different N sources on the relative mobility of some nutritionally important anions and cations and their relevance to plant growth, root development, and pH distribution pattern in the rhizosphere of wheat (Triticum aestivum cv. Nourin No. 61). Experiment was conducted on a Ja… Show more

“…Fertilizers are divided into inorganic and organic ones in their chemical forms. By the application of inorganic fertilizers, the concentrations of available nutrients in the rhizosphere often became higher than those in the non-rhizosphere (Okajima and Taniyama 1980;Lee et al 1997;Miah et al 1998). Besides inorganic fertilizers, organic fertilizers have been utilized for a long period of time.…”

“…Determined by the methods of Miah et al (1998), the soil characters of the experimental site were silty clay loam having a pH (5.5), total nitrogen (0.054%) and organic matter (1.38%). The experiment was laid out in a Randomized Complete Block Design (RCBD) comprising the treatment combinations T 0 (No nitrogen), T 1 (50 kg N ha -1 ), T 2 (75 kg N ha -1 ), T 3 (100 kg N ha -1 ), T 4 (125 kg N ha -1 ), T 5 (150 kg N ha -1 ) with urea as N source and replicated four.…”

“…Eight plants were randomly selected from each plot to study the nutrient accumulation and their uptake. N, P, K, Mg, S, and Zn contents in red amaranth were determined (Miah et al, 1998) at soil chemistry laboratory of BSMRAU using AAS (Model Z-9000, Hitachi Co., Japan). Nutrient uptake was calculated from nutrient contents and dry matter yield and statistical analyses were performed by the method of Gomez and Gomez (1984).…”

“…So the trend of Mg uptake in red amaranth of the current experiment was corroborated by the findings of Kirkby and Mengel (1976). However, it remained to be studied whether the application of increased N levels had a positive effect on Mg uptake or not since the crop was grown only for one season which is not enough to conclude on plant nutrient uptake (Miah et al, 1998).…”
