Research ArticleOpen accessIn the keywordsPerformance of Hevea brasiliensis on Haplic Ferralsol as Affected by Different Water RegimesShafar Jefri Mokhatar, Noordin Wan Daud, Nazera ArbainProblem statement: Rubber has been grown more than a century in South East Asia, who has been the largest producer of natural rubber. Demand of natural rubber increases steadily due to increasing demand particularly from developing countries. Water has been a limited and invaluable resource especially in agriculture. This resource has to be used wisely and there is a need … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 8,905 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPhysiological Response of Soybean (Glycine max) to Foliar Application of Methanol Under Different Soil MoisturesFarzad Paknejad, Mojtaba Mirakhori, Majid Jami Al-Ahmadi et al.Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,150 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEvaluation of Sorghum Density As Affected By Two Water Qualities Under Drip Irrigation SystemB.A. Ould Ahmed, T. Yamamoto, M. Inoue, H. DehghanisanijPot experiment was conducted under glasshouse conditions during 2005 at the Arid Land Research Center, Tottori University in Tottori, Japan. The study presented here was aimed to evaluating the response of sorghum (Sorghum bicolor (L) Moench), density under two different water qualities. The investigation was carried out in randomized complete block design experiments located in a plastic greenhouse.

Research ArticleOpen accessIn the keywordsStomatal Resistance to Low Leaf Water Potential at Different Growth Stages Affects Plant Biomass in Glycine max L.F.B. Adejare, C.E. UmebeseTwo cultivars of Glycine max (L) Merril. (TGX536-02D and TGX 923-2E designated cv.A and cv.B respectively), were subjected to water stress for a period of 7 days at the vegetative (T2), flowering/fruiting (T3) and seed development (T4) stages of growth, with a control (T1). Stress was considered moderate at T2 stage (ψw : -1.53 to -1.57 MPa) and severe at … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,349 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsModeling of Stress- Strain Curves of Drained Triaxial Test on SandAwad Al- Karni, Abdulhafiz AlshenawyThis paper presents a hyperbolic mathematical model to predict the complete stress-strain curve of drained triaxial tests on uniform dense sand. The model was formed in one equation with many parameters. The main parameters that are needed to run the model are the confining pressure, angle of friction and the relative density. The other parameters, initial and final slopes of … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 6,838 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsINCREASED NUTRIENT SOLUTION CONCENTRATION DURING EARLY FRUIT DEVELOPMENT STAGES ENHANCES PUNGENCY AND PHENYLALANINE AMMONIA-LYASE ACTIVITY IN HOT CHILI (CAPSICUM ANNUUM L.)Parichat Dittakit, Thammasak ThongketThe effect of increased nutrient concentration during different fruit development stages on the yield, pun-gency and PAL enzyme activity in hot chili cv. ’Super hot’ was studied during August 2009-January 2010. The seedlings were planted in plastic containers containing 20 L of coconut-coir-dust substrate placed inside a plastic-roofed net house and received Resh’s Tropical Dry Summer nutrient solution at a … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 7,492 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSustainable Technology for Agriculture at Extreme Altitudes: Design and Evaluation of a Sprinkler Irrigation System in a Peruvian High Andean CommunityJuan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Daniel Olivier Carranza Lizana et al.In high-altitude agroecosystems, erratic rainfall patterns and steep topography severely constrain crop productivity by exposing plants to soil water deficits during critical phenological stages. This study aimed to enhance the productivity of eleven staple and horticultural crops corn (Zea mays), tomato (Solanum lycopersicum), cucumber (Cucumis sativus), eggplant (Solanum melongena), lettuce (Lactuca sativa), carrot (Daucus carota), barley (Hordeum vulgare), celery (Apium … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 2 Oct 2026 · 645 accessesView PDF Cite

Research ArticleOpen accessIn the abstractClimate-Driven Productivity Responses and Implications for Genetic Adaptation and Breeding of Boreal Trees in KazakhstanZhadyra Baigazakova, Kuralay Mazarzhanova, Asset Satayev et al.Kazakhstan’s boreal and forest-steppe forests form the southern ecotonal edge of the West Siberian taiga, where relatively small changes in heat and moisture can trigger disproportionate impacts on tree growth, mortality, and regeneration. Although forests cover only ~4% of Kazakhstan, they provide critical ecosystem services: stabilizing hydrological regimes, buffering microclimates, protecting agricultural lands from wind and water erosion, and supporting … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 10 Aug 2026 · 709 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpatial-Dynamics of Trace Metals Accumulation and Physicochemical Characteristics in Ikpukulu-Ama Creeks, Rivers State, NigeriaDavies Ibienebo Chris, Khang Wen Goh, Davies Imachrist Ibienebo et al.The study examines the spatial-dynamics variability of water parameters and trace metal concentrations between January and June 2023 at the Ikpukulu-Ama sites of the Bonny River, Nigeria. Key parameters analyzed include temperature, salinity, pH, transparency, dissolved oxygen, and trace metals (Ni, Pb, Cd, Cu, Zn) across three sites. The highest temperature, 32.56°C, was recorded at Site 2, indicating potential thermal … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 29 Jul 2026 · 494 accessesView PDF Cite
