rice is the world's most important food crop. to decrease the damage of rice pests, development of insect pest management strategies in rice is necessary. biennial results for determination of a suitable method to control striped stem borer in rice showed that integration of two methods of control (biological and mechanical) is a feasible effort to reduce stem borer infestation. to assure...
This study seeks to provide insights on understanding the contemporary problems of energy efficiency in Ukrainian universities by developing a comprehensive energy efficiency management framework that encompasses its participating subjects, objects and key drivers along with suggesting its implementation mechanism and tools. Emphasis should be given that the current situation of inefficient and...
Rice – wheat cropping system is backbone of agriculture and responsible for achieving food security in the country. However, because threat to sustainability this there urgent need crop diversification. A field experiment diversify rice wet zone Himachal Pradesh was carried out during year 2017-18 at Bhadiarkhar research farm, Department Agronomy, CSK HPKV, Palampur evaluate productivity, profi...
In current research, energy efficiency and technical efficiency of wheat farmers were calculated in Mazandaran province. To estimate technical efficiency the Stochastic Nonparametric Envelopment of Data (StoNED) was used. The model incorporating nonparametric data envelopment analysis model which contain the smoothness and concavity constraints with stochastic frontier analysis model. The requi...
The most important problem in achieving high yields in rice is how to increase the nitrogen (N) absorption at each growth stage without reducing the percentage of ripened grains. Proper amount and timing of application could reduce N losses and increase fertilizer use efficiency while cost of production is also reduced and yield is increased. In order to avoid losses and to use soil-and fertili...
Background : Industrial wastewaters contain organic pollutant such as dyes, halogenated hydrocarbon, phenolic compounds and so on Rice husk is a cheap material which is new available in our country. The aim of this study is removal efficiency comparing rice husk ash performance with commercial granulated activated carbon in removal of 2-CP and 4-CP from aqueous solutions. Methods : Experime...
integration reinforcement of renewable energy resources and phevs through hybrid ac-dc local network
the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
Rice is considered as one of the most strategic plants in Iran. The production of rice has been confronted with new challenges since the year of 2000, so the necessity of supporting policies implemented by all relevant authorities has been revealed more and more. Average rainfall records in Gilan province, a rice-favored tropical region, often show a range of 800 ml – 2000 ml with the latter nu...
The determination method of total arsenic (As) and the speciation method of inorganic As for non-glutinous rice reported in our preceding paper were applied to several varieties of rice under optimized experimental conditions. In the determination of total As with ICP-MS, acetic acid was added to increase the sensitivity and an internal reference method with germanium was adopted to increase th...
