Research ArticleOpen accessIn the abstractThe Time of Flooding Occurrence is Critical for Yield Production in Rice and Vary in a Genotype-Dependent MannerJenjira Mongon, Arom Jantasorn, Prateep Oupkaew et al.Flash floods occur in rainfed lowland and flood-prone areas and have a profound incidence on crop yield, which is tightly linked to worldwide food insecurity. The most flooding-threatened crop is rice. Under this condition, rice undergoes anoxic and post-anoxic shock that affects its growth, development capacity and ultimately causes an important grain yield loss. Therefore, the introduction of submergence-tolerant varieties … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 3 Jun 2017 · 8,096 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiallel Analysis and Evaluation of Parents and F1 Progenies of Maize (Zea mays L.) for Tolerance to Drought and Striga hermonthica (Del.) Benth in the Guinea Savanna Agro-Ecological Zone of GhanaAlhassan Bawa, Isaac Kwahene Addai, Mashark Seidu Abdulai, Al-Hassan IssahakuField studies were conducted to evaluate 6 parents and 30 F1 hybrids of maize for tolerance to drought and Striga hermonthica in Nyankpala, Ghana during the 2014 and 2015 cropping seasons. These genotypes were evaluated for two years on single-row plots of three replicates, in a randomized complete block design. The control plants were planted in July each year which … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 1 · 25 Mar 2017 · 8,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Approach to Study Stimulating Effect of the Pre-Sowing Barley Seeds Treatment in the Electromagnetic FieldAliya S. Kasakova, Igor V. Yudaev, Michael G. Fedorishchenko et al.Improvement of the agricultural crops seeds quality with their pre-sowing treatment in the electromagnetic field and the subsequent increase in grain yield and studying the mechanisms of stimulating effects – all those are the important problems of science and practice of the crop-growing sector. The purpose of the presented research was to study the mechanism for increasing the germinating ability … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 4 May 2018 · 7,351 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Subacute Ruminal Acidosis on Milk Fatty Acid Profile in Dairy CattleC. Mitchell, O. ALZahal, M.M. Or-Rashid et al.The objective of this experiment was to examine the effect of Subacute Ruminal Acidosis (SARA) on milk fatty acid (FA) profiles with emphasis on odd-chain and branched-chain FA. Sixteen multiparous Holstein dairy cows (618±35 kg of body weight, 221±32 days in milk) were used in a randomized complete-block design. During week 1, all cows received a high-forage diet (90% chopped … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 2 · 27 Apr 2016 · 7,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractModels of Winter Wheat Yield Based on Calcareous Chernozem Fertility ParametersOlga A. Biryukova, Dmitry V. Bozhkov, Tatiana M. Minkina et al.The use of polyelement diagnostics and regression analysis for predicting the yield of winter wheat at different stages of vegetation is considered. It has been established that the prediction and integrated assessment of grain yield and quality should be performed with consideration for the balance of macro-and micronutrients in the grain and the aboveground biomass of plants. Possibility of predicting … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 1 Jan 2016 · 7,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponses of Rice to Green Manure and Nitrogen Fertilizer ApplicationMd Safiqul Islam, Nitish Kumar Paul, Md Robiul Alam et al.The effect of green manure and nitrogen fertilizer applications on rice performance and post-harvest nutrient status of the soil was studied at the Regional Wheat Research Station of Bangladesh Agricultural Research Institute (BARI), Shyampur, Rajshahi, Bangladesh. The experiment comprised two sets of treatments: (i) green manure application (Crotalaria jusncea, Sesbania aculeata, Sesbania rostrata,Vigna radiata, and Phaseolus mungo) and (ii) application … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 1 Sep 2015 · 7,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION OF N ADDITIVES FOR IMPROVING N USE EFFICIENCY OF SURFACE APPLIED UREA TO DRY SEEDED AND PERMANENTLY FLOODED RICEDavid D. Dunn, Pawel WiatrakThere are several potential Nitrogen (N) loss mechanisms in a dry seeded and delayed flood system rice (Oryza Satvia L.) production system including urea volatilization and denitrification. The scope and magnitude of these potential losses are largely weather dependent. Two additives (stabilizers), Agrotain and Nutrisphere-N, have been offered to rice producers for controlling these potential losses. This study compared these … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 21 Jun 2014 · 6,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION 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 abstractEFFECT OF UREA WITH NUTRISPHERE-N POLYMER IN FALL AND SPRING NITROGEN APPLICATIONS FOR CORNPawel Wiatrak, Walter B. GordonPolymer coated urea may be a viable option to improve Nitrogen (N) uptake and corn (Zea mays L.) grain yields, especially in areas with relatively high soil N loss. The objective of this study was to evaluate the effect of two urea application timings (fall and spring) and three N rates (90, 180 and 270 kg N ha-1) with and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 8,153 accessesView PDFCite
