Yield of Wheat (<i>Triticum aestivum</i>) and Nutrient Uptake in Grain and Straw as Influenced by Some Macro (S & Mg) and Micro (B & Zn) Nutrients

Abstract

A wheat variety BARI Gom 26 was cultivated with an objective of evaluating the effects of macro/secondary nutrients as S and Mg, and micro nutrients as B and Zn on yield, yield contributing traits and nutrient uptake status by the crop. The field experiment was conducted in the "North Eastern Barind Tract Soils" at Kushadaha, Nawabganj, Dinajpur, Bangladesh from November, 2014 to March, 2015. The surface soil was clay in texture, having pH 5.61, organic matter 1.58%, total N 0.10%, available P 7.03 ppm, exchangeable K 0.11 meq/100g, available S 2.57 ppm, exchangeable Mg 0.55 meq/100g, available Zn 1.30 ppm, available B 0.08 ppm. The experiment was designed with five treatments laid out in a randomized complete block design (RCBD) with three replications. The treatments were T 1 : NPK (control), T 2 : NPK + S, T 3 : NPK + S + Mg, T 4 : NPK + S + Mg + Zn and T 5 : NPK + S + Mg + Zn + B. All plots of wheat received 100 kg N/ha, 30 kg P/ha and 70 kg K/ha as basal dose. The secondary and micro nutrients doses were 15 kg S/ha, 6 kg Mg/ha, 2.5 kg Zn/ha and 1.5 kg B/ha. Results revealed that the plant height, tillers/hill, 1000-grain weight, yield of grain and straw, uptake of some specific nutrients in grain and straw were significantly influenced by all the treatments, though these treatments did not show any identical effect on spike length, content of P and Mg in wheat. Significantly highest amount of 1000-grain weight, yield of grain and straw weight of wheat were obtained in applying T 2 treatment that employed the addition of S with recommended dose of NPK. Significant positive effects were also observed for the rest parameters in receiving the treatments composed of secondary and micronutrients (T 3 , T 4 , and T 5 ). The highest concentration of nutrient uptake N, P, K and S in grain and straw of wheat were also obtained due to the application of T 2 treat-

Nitrogen flow in livestock waste system towards an efficient circular economy in agriculture

“…N content in the straw was high across all the treatments showing a relatively good uptake of N by the root system. Earlier result from our study had showed a well-developed root system across both soil types which gives credence to findings where improvement of the uptake of macronutrients with the addition of N is associated with the good development of the root system and the efficient application of N (Azad et al, 2021). Furthermore, with respect to C content in straw, lower content observed in the acidic soil showed a lower mineralization rate of organic C, subsequently resulting in slower uptake.…”

Effects of Different Kinds of Fertilizers on the Vegetative Growth, Antioxidative Defense System and Mineral Properties of Sunflower Plants

“…Mohamed et al [60] found that organic fertilizer treatments enhanced macro and micronutrient availability over inorganic fertilization, which is in line with our results. Furthermore, Azad et al [61] observed that the prescribed amount of inorganic fertilizer enhanced the content of N, P, K, and S in wheat grains significantly.…”
