Research ArticleOpen accessPhrase in the titleCorn 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 PDF Cite

Research ArticleOpen accessIn the keywordsNuclear Posture Review: Kahn Vs. Schelling…and PerryTimothy Sands, Harold Camacho, Richard MihalikThe 2018 American Nuclear Posture Review includes a revived emphasis on deployed, low-yield nuclear options to reserve credible deterrence against countries that have transmitted beliefs the U.S. would not respond to employment of non-strategic nuclear weapons, since there is a mistaken perception that the U.S. could only respond with high-yield strategic weapons, which would be deemed unacceptable. An important question … …Journal of Social Sciences, Vol. 14, Issue 1 · 30 Apr 2018 · 9,278 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsTheoretical Context of the Nuclear Posture ReviewTimothy Sands, Richard Mihalik, Harold CamachoThe very recently published 2018 American Nuclear Posture Review hails the revived emphasis on deployed, low-yield nuclear options to reserve credible deterrence against countries that have transmitted beliefs the U.S. would not respond to employment of non-strategic nuclear weapons, since there is a mistaken perception that the U.S. could only respond with high-yield strategic weapons, which would be deemed unacceptable. … …Journal of Social Sciences, Vol. 14, Issue 1 · 30 Mar 2018 · 8,079 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsRice Yield Related to Fertilizers Applied by Farmers on Two Areas of Marginal Peat Soil in Bengkulu IndonesiaRidha Rizki Novanda, Satria Putra Utama, Andi Ishak, Muhammad Faiz BarchiaThe research was intended to identify amounts of fertilizers applied by small-scale farmers related to rice yield cultivated on marginal peat soils in irrigated paddy fields in Bengkulu. The study was conducted at two peat areas; Pekik Nyaring Village, Air Hitam irrigated rice fields in Central Bengkulu and Sumber Makmur Village, Air Manjuto irrigated areas, Mukomuko Bengkulu Province from June … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 10 Jan 2021 · 7,579 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetermination of Crop Yield Detection and Prediction With Multimodal Data Using Fusion TechniquesKutlwano Sedimo, Rajalakshmi Selveraj, Venumadhav Kuthadi, Thulaganyo DimakatsoMost often, soil, environmental, and agronomic data are used in pieces, hence limiting the performance of crop selection and yield forecasting. This study develops an integrated, fusion-based framework that combines soil image classification, environmental feature analysis, and input-driven yield prediction to support precise agricultural decision-making. The system consists of three major modules: (i) a CNN for the classification of soil … …Journal of Computer Science, Vol. 22, Issue 10 · 5 Oct 2026 · 494 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMachine Learning Based Prediction of Catch Yields in Small Scale FisheriesEpifelward Niño Olaivar Amora, Patrick D. CernaSmall-scale fisheries are critical for food security and livelihoods but increasingly face threats from overfishing and environmental change. This study employed machine learning to predict catch yields in Cogtong Bay, Philippines, using 3,478 records collected in 2020–2021 that included species, gear, location, season, and weather data. Models developed in Python with scikit-learn and XGBoost compared Random Forest (RF), Extreme Gradient … …Journal of Computer Science, Vol. 22, Issue 8 · 24 Aug 2026 · 1,117 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,991 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdaptation and Use of the Gangaria Seed Drill for the Improvement of Peanut (Arachis hypogaea) Cultivation in Niger: Case of the Maradi and Zinder RegionsAbdoulahi Mamane, Arifa Warouma et al.In Niger, peanut cultivation plays a significant role in food security and improving the incomes of rural households, particularly in the Maradi and Zinder regions. However, this crop remains hampered by low mechanization, the use of traditional tools, and inefficient fertilization, resulting in consistently low yields of around 600 to 800 kg/ha. Faced with these constraints, this study aims to … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 6 Feb 2026 · 2,843 accessesView PDF Cite

Research ArticleOpen accessIn the abstractResponse of Cowpea (Vigna unguiculata L. Walp.) Varieties to Striga gesnerioides (Willd.) Vatke InfestationAlhassan Bawa, Ismael Yakubu, Yussif SeiduProduction of cowpea within the sub-Saharan Africa, and Ghana in particular, is bedeviled with many challenges, including Striga infestation, resulting in abysmal low grain and biomass yields. Thus, the study was conducted to evaluate Striga's impact on cowpea growth and yield. During the 2023 agricultural season, the study was carried out in Northern Ghana. A control (non-infested) experiment and a … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 18 Sep 2025 · 4,874 accessesView PDF Cite
