“Mutagenic Dosimetry in Gladiolus (Gladiolus grandifloras L.) with Sodium Azide”
Esta investigación se realizó en la Comunidad Número Ocho, en distrito de Acobamba, región Huancavelica. El experimento se llevó a cabo en un ambiente protegido (invernadero rustico). El objetivo fue evaluar el efecto del agente mutagénico azida sódico para inducir mutaciones en los bulbos de gladiolo. El experimento se realizó utilizando el diseño estadístico DCA (Diseño Completamente al Azar), con nueve tratamientos y con 4 repeticiones por tratamiento. Cada unidad experimental estuvo conformada por 5 bulbos, cada uno se evaluó emergencia de plántulas, altura de planta, diámetro de tallo, longitud de raíz, numero de foliolos. Asimismo, se empleó la prueba de comparación múltiple de Duncan manteniendo un nivel de significación de 5% para los promedios de las variables cuantitativas y se determinaron las medidas de centralización y de dispersión para evaluar los valores mínimos y máximos, así como para interpretar el coeficiente de variación. El efecto promedio de la azida de sodio en la estimulación o inhibición de caracteres morfológicos de las plantas se observó que el promedio más alto (10.17) se logró con la dosis de 3.0 mM. Los valores más bajos se encontraron con la dosis de 3.5 Mm (2.80) y el testigo Buffer (2.69). La dosis óptima de azida de sodio que provoca efectos los deseados en plantas de gladiolo fue de 3.0 mM.This research was carried out in the comunidad numeri ocho, in the district of Acobamba, Huancavelica region. The experiment was carried out in a protected environment (rustic greenhouse). The objective was to evaluate the effect of the mutagenic agent sodium azide to induce mutations in gladiolus bulbs. The experiment was conducted using the statistical design DCA (Completely Randomized Design), with nine treatments and with 4 repetitions per treatment. Each experimental unit was conformed by 5 bulbs each one, it was evaluated seedling emergence, plant height, stem diameter, root length, number of leaflets. Also, it was used Duncan's multiple comparison test maintaining a significance level of 5% the averages of the quantitative variables and there were determined the centralization and dispersion measures to evaluate the minimum and maximum values, as well as to interpret the variation coefficient. The average effect of sodium azide in the stimulation or inhibition of morphological characters of plants was observed that the highest average (10.17) was achieved with the dose of 3.0 mM. The lowest values were found with the dose of 3.5 Mm (2.80) and the Buffer control (2.69). The optimal dose of sodium azide causing desired effects in gladiolus plants was 3.0 mM
Effects of the Behavior of two natural enemies to reduce populations of (heliothis zea) in the Corn Corn crop
La presencia de plagas en el cultivo del Maíz en su etapa de choclo ha causado pérdidas económicas en el Perú. El estudio surge como objetivo: Evaluar la efectividad de dos predadores en estudio en control de Heliothis zea. en el cultivo de maíz, comparar la efectividad de dos enemigos naturales del Heliothis zea; Para ello se seleccionaron tres lotes de maíz variedad San Jerónimo, en etapas de floración, maduración para evaluar porcentajes de predacion de insectos en estudio fenológicas, Las observaciones en campo se realizó cada 10 días, teniendo presencia de predadores de Orius insidiosus (Hemiptera: Anthocoridae). Los estados inmaduros del mazorquero (Heliothis zea). Se evaluaron en tres etapas floración, fructificación y maduración. Los resultados encontrados de predacion Coleomegilla maculata y Orius insidiosus, La etapa de floración el C. maculata tiene un 13.71 % en los diferentes estados del Heliothis zea, siendo menor porcentaje 12.71 % de Orius insidiosus esto se debe a que C. maculata tiene mayor actividad en estadios larvales, La etapa de maduración C. maculata alcanza 24.71 % y Orius insidiosus 26.71%. El porcentaje de predacion de insectos en estudio mostraron mayor actividad predatora el Orius insidiosus, C. maculata y Orius insidiosus en la etapa de floración del cultivo de maíz.The presence of pests in the cultivation of maize in its choclo stage has caused economic losses in Peru. The study aims to: Evaluate the effectiveness of two predators under study in control of Heliothis zea. in maize cultivation, compare the effectiveness of two natural enemies of Heliothis zea; For this purpose, three batches of maize variety Saint Jerome were selected, in flowering stages, maturation to evaluate percentages of predation of insects in phenological study, Observations in the field was made every 10 days, having the presence of predators of Orius insidiosus (Hemiptera: Anthocoridae). The immature states of the mazorquero (Heliothis zea). They were evaluated in three stages flowering, fruiting and maturation. The results found from predation Coleomegilla maculata and Orius insidiosus, the flowering stage C. maculata has 13.71 % in the different states of Heliothis zea, being less percentage 12.71 % of Orius insidiosus this is because C. maculata has greater activity in larval stages, the maturation stage C. maculata reaches 24.71 % and Orius insidiosus 26.71%. The percentage of predation of insects under study showed increased predatory activity in Orius insidiosus, C. maculata and Orius insidiosus at the flowering stage of maize cultivation

Conversion of lignocellulose biomass to bioenergy through nanobiotechnology
The growing global demand for energy, particularly petroleum-based fuels, has stimulated a long-term quest for an optimal source of sustainable energy. This barrier is removed by lignocellulosic biomass, which is an economical, easily accessible, and renewable fuel source that fits sustainability standards. However, large-scale use of most of the techniques results in significant handling costs and decontamination of the inhibitors released. Taken together, these limits increase the efficacy of present solutions and create a need for the development of a novel, environmentally sustainable, productive, and cost-effective technology for lignocellulose biomass conversion. In this context, the use of nanotechnology in the treatment of lignocellulose biomass to bioenergy exchange has gained significant attention and has been extensively researched in recent years. This review discussed how nanotechnology can be used to turn biomass into energy. It gives new ideas and tools for developing new industries, which will help the economy, grow in the long run. This careful examination will also shed light on some of the minor details surrounding the different ways of biomass conversion previously explored by other experts
Intensifying Effects of Climate Change in Food Loss: A Threat to Food Security in Turkey
Turkey is increasingly concerned about the effects of climate change, weather unpredictability, and severe events on agricultural production, food loss, and livelihoods. Turkey has long struggled against climate variability and catastrophic climatic events to prevent further declines in agricultural output. This study assessed the risk of climate change in Turkey from the perspective of loss in food grains and food security domain considering exposure to extreme climate events using the data from 1991 to 2019. This paper makes a theoretical contribution to the literature by identifying the relationship between food waste and food import, food prices and economic growth. It also makes an empirical contribution by administering and econometrically analyzing the impact of the loss of food grains on the aforementioned independent variables. Policy implications for the current national agriculture policy were provided using the vector auto-regression (VAR) model and derivative analysis. Food grain loss negatively correlates with food security since it increases reliance on food imports from outside. Moreover, the losses in food supplies contributes greatly to price increases. The GDP growth rate, however, was shown to be a feeble instigator. Climate change threatens food security, and the country’s progress toward sustainable development objectives is hampered in general, particularly concerning no poverty and zero hunger goals. In conclusion, climate change and its associated factors harm Turkey’s food security and economy
