Research ArticleOpen accessEvery word in the titleEfficiency of Nitrogen Fixation by Rhizobium Strains Associated With White Clover in the Ecuadorian Highlands Biological Nitrogen Fixation by White Clover in EcuadorDaniela Michell Chuquimarca Mamarandi, Venancio Saúl Arahana Bonilla, Paulina Andrea Cevallos Hidalgo et al.The objective of this research was to evaluate the nitrogen-fixing capacity of 30 strains of Rhizobium isolated from white clover nodules, collected in the provinces of Pichincha and Cotopaxi under greenhouse conditions. After isolation of the bacteria and authentication of the isolates, a greenhouse experiment was conducted, in a Completely Randomized Design (CRD), with three replications and two controls: with … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 4 Oct 2026 · 835 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Differently Processed Taro Mixed With Other Ingredients on Digestibility and Nitrogen Balance in Crossbred PigsPhiny Chiv, Saravuth Tum, Putheasath Sin et al.Leaves from forage crops and vegetables such as water spinach, sweetpotato, cassava, and especially taro, can be incorporated into pig diets aspartially replace commonly used protein sources including fish meal or/and soybeanmeal. However, their use remains limited among farmers and livestock producers.This study aimed to compare feed intake, determine apparent digestibilitycoefficients, and analyze nitrogen retention in pigs fed various forms … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 7 Jul 2026 · 1,355 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCoix lacryma-jobi L. Nutritional Value Concerning Nitrogen Fertilizer DosesTaufan Purwokusumaning Daru, Mayang Sari, Hamdi MayuluCoix lacryma-jobi L., as animal feed is considered a cereal plant from the Poaceae or Gramineae family. We aimed to determine the influence of different doses of Nitrogen (N) fertilizer on Coix lacryma-jobi L. It was conducted in the Lempake Village area; and the Chemical and biochemical laboratory of agricultural products and animal husbandry nutrition laboratory at Mulawarman University from … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 2 · 3 Jun 2023 · 6,221 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Differentiated Nitrogen Fertilization using Satellite Navigation Systems on the Spring Wheat (Triticum aestivum L.) Crop Yield in the Conditions of Chernozem-Like Soils in the Northern Forest Steppe of the Tyumen Region of RussiaAltynay Oxukbayeva, Nikolai Abramov, Marden Baidalin, Sergei SemizorovSoil cultivation without layers turnover impeded the process of nitrate nitrogen accumulation compared with plowing. The traditional scheme of mineral fertilization applying the averaged standard did not create a heterogeneous level of nutrient supply in primary soil cultivation systems. These factors set them in unequal conditions by default in terms of nitrogen supply to crops. Solid mineral fertilization with the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 16 Jan 2023 · 5,201 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Nitrogen Fertilizer on Grain Yield and Fragrant Contents in two Thai Rice VarietiesAyut Kongpun, Chanakan Thebault Prom-u-ThaiNitrogen (N) is commonly applied in rice crop production for improving grain quality and productivity. This experiment aimed to evaluate how applying N fertilizer affects the concentration of 2-Acetyl-1-Pyrroline (2AP), the major fragrant compound in rice grains, between two selected rice varieties with high yield potential and fragrant scent, Pathum Thani 1 (PTT1) and RD22. Rice plants were grown in … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 18 Jul 2021 · 7,458 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Nitrogen Source on the Lipid Accumulation in Phaeodactylum TricornutumXiaojie Ren, Qi Yan, Song Li et al.Nitrogen source has an important influence on the growth and lipid synthesis of Phaeodactylum tricornutum. It affects lipid accumulation through global metabolic regulation. However, little research has been done on the correlation between other metabolites and lipid metabolism during the synthesis of Phaeodactylum tricornutum. In this study, we studied the effect of different nitrogen sources on lipid and other major … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 27 Jul 2020 · 6,913 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResponses of Milling Quality to Nitrogen and Water Management in Modern Long Grain Rice VarietiesThitinan Sreethong, Benjavan Rerkasem, Bernard Dell et al.This study determined how nitrogen (N) fertilizer and water management affect grain yield and milling quality of 9 modern rice varieties with long, slender grain in two field experiments. The effect of N on rice grown in wetland culture was evaluated at 0, 60 and 120 kg N ha-1. In a second experiment the rice in aerobic and wetland culture … …OnLine Journal of Biological Sciences, Vol. 19, Issue 4 · 31 Oct 2019 · 7,224 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Investigation of Biological Nitrogen Fixation in Critical Dryland PastureSyamsuddin Hasan, Budiman, Asmuddin Natsir et al.The aim of the study is to determine the production and growth of dwarf napier grass (Pennisetum purpureum cv.mott) integrated with siratro legumes (Macroptilium atropurpureum) contributing to the availability of preferred forage for ruminants on critical dryland. The study applied randomized block design consisted of 4 groups and 4 treatments; P0 consisted of 100% control Pennisetum purpureum cv.mott; P1 consisted … …OnLine Journal of Biological Sciences, Vol. 19, Issue 3 · 26 Jul 2019 · 7,937 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStable Nitrogen Isotopic Changes in Winter Wheat (Triticum aestivum L.) Induced by its Growth TemperatureZhou Feng Wang, Wei Guo Liu, Rui Juan HaoThe nitrogen dynamics of plants can be quantified using the variation in their δ15N level. This reveals details of plant physiological characteristics and the relationship between plants and their growth conditions. To better understand plant nitrogen dynamics and the effects of external temperature changes on their nitrogen isotopic composition, we investigated the δ15N characteristics in Triticum aestivum and its mother … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 1 · 21 Mar 2017 · 8,119 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpatial Analysis and Modeling the Nitrogen Flush after Rainfall Events at the Field Scale in SWATElizabeth Brooke Haney, Richard Lee Haney, Jeffrey George Arnold et al.Current nitrogen (N) models tend to neglect the contribution of the microbial population to the plant available N pool, resulting in an underestimation of yield and possible over or underestimation of N runoff from natural and agricultural landscapes. We used the measurement of microbial activity coupled with the measurement of their food source, water extractable nitrogen (N) and carbon (C), … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 11 Apr 2016 · 7,228 accessesView PDFCite
