Research ArticleOpen accessIn the keywordsCorn (Zea Mays L.) Plant Characteristics and Grain Yield Response to N Fertilization Programs in No-Tillage SystemKesi Liu, Pawel WiatrakProblem statement: Nitrogen application timing and Nitrogen (N) rate are two important factors to influence corn production in No-Tillage (NT) system, but N recommendations may need to be revised due to insufficient rainfall in dryland rain-fed environment. Approach: This study was to determine the effects of two N application timing (planting and split application at planting and V6 corn growth … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 25 Mar 2011 · 8,343 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCorn Response to Nitrogen Timing and Rate under Strip Tillage and Low-Yield Environment in Southeastern Coastal PlainsPawel Wiatrak, Ahmad Khalilian, Guihua ChenProblem statement: Insufficient rainfall under low yield environment may affect nitrogen management, plant growth indices and grain yields of corn (Zea mays L.). Approach: The objective of this study was to determine the effects of two N application timings (all at planting and as split application with N applied at planting and V6 stage) and five N fertilizer rates (0, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 7,994 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUSE OF SALINE WATER FOR GREENHOUSE BELL PEPPER (CAPSICUM ANNUUM) PRODUCTIONV. C. Patil, K. A. Al-Gaadi, M. A. Wahb-Allah et al.A greenhouse experiment was conducted to study the response of bell pepper to quality of irrigation water and irrigation regimes. The main treatments included non-saline water (EC-0.5 dS m-1) and saline water (EC-3.5 dS m-1). The sub-treatments included three irrigation regimes (at 100, 80 and 60% of crop Evapotranspiration (ETc)) in combination with three crop growth stages (vegetative, flowering to … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 1 Feb 2014 · 8,611 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEVALUATION OF NITROGEN APPLICATION METHODS AND RATES WITH NUTRISPHERE-N ON CORN IN SOUTHEASTERN COASTAL PLAINSPawel WiatrakApplication method of Nitrogen (N) and Nutrisphere-N may influence corn (Zea mays L.) growth and yields under dryland conditions. The objective of this study was to determine the effect of two N application methods (all at planting and split application with 35 kg N ha-1 applied at planting and remaining N at V6 stage) and five N rates (0, 45, … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 4 Jan 2014 · 7,301 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Foliar Bio-Based Fertilization on Spring Wheat (Triticum Aestivum L.) in Reconciling Productivity and Alleviation of Environmental Concerns Under Semi-Arid ConditionsGani Stybayev, Raushan Ramazanova, Kelvin Harrison Diri et al.A two-year randomized field trial was conducted to evaluate the effects of foliar bio-based fertilization on the growth, productivity, grain quality, and soil health of spring wheat (Triticum aestivum L.) under semi-arid conditions in Northern Kazakhstan. Four treatments were compared: T0 (100 kg Ammophos, mineral fertilizer control), T1 (50 kg N14P23 + biotreatment), T2 (25 kg N14P23 + biotreatment), and … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 3 Apr 2026 · 1,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Disease Index Based on Multi-Spectra of UAV to Estimate Cotton DiseaseBing Chen, Jing Wang, Qiong Wang et al.Verticillium wilt is a significant disease that affects cotton plants, which can lead to stunted growth and reduced yield. To address this, a multi-spectral comprehensive monitoring disease index model is developed using an Unmanned Aerial Vehicle (UAV) to monitor the severity of cotton Verticillium wilt. First, multi-spectral dates were collected from Hexacopter (HY-6X) and the phenotype disease grade of cotton … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 25 Mar 2024 · 5,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of the Effects of Soil Salinity on the Growth and Development of Maize (Zea Mays L.) by using Sentinel-2 ImageryShakhislam Uzakbaevich Laiskhanov, Zhassulan Maratuly Smanov, Kulyash Duisenbaevna Kaimuldinova et al.Salinization of soil cover and the constant increase in their area have become one of the most pressing problems year after year for irrigated agriculture regions. The degradation processes caused by the salinity of soils negatively affect the growth and development of food crops. Therefore, this study focused on the effects of soil salinity in the midstream of the Syrdarya … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 15 Aug 2022 · 6,261 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructure and Diversity of Agroforestry Parklands in the Sudano-Sahelian Zone of CameroonAwé Djongmo Victor, Noiha Noumi Valery, Zapfack LouisThe general objective of the study is to characterize the woody vegetation of 05 agroforestry parkland in the Sudano-Sahelian zone of Cameroon. A total of 40 floristic surveys of 200  20 m were carried out. A total of 33 species in 20 families and 31 genera were recorded. The dendrometric survey method enabled us to characterize the vegetation of … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 2 Apr 2021 · 7,816 accessesView PDFCite
Research ArticleOpen accessIn the abstractIN-SEASON ASSESSMENT OF WHEAT CROP HEALTH USING VEGETATION INDICES BASED ON GROUND MEASURED HYPER SPECTRAL DATAKhalid Ali Al-Gaadi, Virupakshagouda Patil, ElKamil Tola et al.An experiment on a 50 ha center pivot field was conducted to determine the Vegetation Indices (VI’s) that were helpful in assessing the in-season performance of wheat crop treated with graded levels of irrigation water and fertilizers. The irrigation levels were at 100, 90, 80 and 70% evapotranspiration (ETc); however, the fertilizer levels of N: P: K kg-1ha included 300:150:200 … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 7 Jan 2014 · 7,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Worldview-2 Satellite Imagery to Support Geoscience Studies on Phlegraean AreaPasquale Maglione, Claudio Parente, Andrea VallarioWorldView-2 satellite imagery includes half-meter panchromatic resolution and 2 m multispectral resolution.
