Research ArticleOpen accessPhrase in the titleUsing Soil Plant Analysis Development Chlorophyll Meter for Two Growth Stages to Assess Grain Yield of Malaysian Rice (Oryza sativa)Asa Gholizadeh, Mohd Amin Mohd Soom, Anuar Abd. Rahim, Aimrun WayayokProblem Statement: Proper yield management in rice influences grain quality and quantity. Nitrogen site-specific management is also effective on final product of crops because excessive nitrogen application at any growth stage can reduce yield and increase disease incidence. In contrast, suboptimal nitrogen levels at discrete growth stages may substantially reduce plant productivity. The nitrogen status at specific growth stages may … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 11,820 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCorn (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 · 8,340 accessesView PDFCite
Research ArticleOpen accessPhrase 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 accessPhrase in the titleResponses of Grain Yield and Nutrient Accumulation to Water and Foliar Fertilizer Management in Upland and Wetland Rice VarietiesNatdanai Juntakad, Sittichai Lordkaew, Sansanee Jamjod, Chanakan Prom-u-thaiThis study evaluated the effects of water and fertilizer managements on grain yield and nutrient accumulation in upland and wetland rice varieties. The two rice varieties representing upland (KH CMU) and wetland (CNT1) ecotypes were grown in different water conditions and fertilizer managements. The interaction between variety and water condition had significantly affected on grain yield and straw dry weight. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 May 2018 · 8,356 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Spring Wheat Mutation Resources with Improved Grain Quality, Metals Bioavailability and Yield ComponentsSaule Kenzhebayeva, Alfia Abekova, Guoping Zhang et al.Genetic variability in micronutrients is limited in wheat varieties. To broaden variation, seeds of cv. Eritrospermum-35 were irradiated with 100 and 200 Gy using 60Co, the treated seeds were grown to M7 generation with successive selection of the highest yield lines in each generation. Selected lines were evaluated for yield and grain quality traits such as iron, zinc and phytic … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 4 · 2 Jan 2018 · 8,672 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFECT OF DROUGHT CONDITION ON GROWTH, YIELD AND GRAIN QUALITY OF UPLAND RICERaumjit Nokkoul, Teerayut WichitparpThus, the objective of this study was to investigate the effect of drought condition on growth, yield and grain quality of two varieties in upland rice: Nangdam and Lebnok. The experiment was performed at the King Mongkut’s Institute of Technology Ladkrabang, Chumphon Campus, Thailand during July to November, 2010. The study was conducted in randomized complete block design with four … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 26 Jul 2014 · 7,269 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Integrated Weed Management on Yield and Yield Component of Bread Wheat in Guji Zone, Southern OromiaLulu Misgana, Yared Tesfaye, Dagne Abu et al.Bread wheat (Triticum aestivum L.) is one of the most important food crops in the world, providing a staple food for over 35% of the global population; in Ethiopia, however, production in highland regions like the Guji zone is severely constrained by heavy weed infestation, causing significant yield gaps. While Integrated Weed Management (IWM) is a promising solution, locally validated … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 5 Dec 2025 · 3,424 accessesView PDFCite
