ABSTRACT
The present field investigation was conducted for two consecutive Rabi seasons of years 2021/22 and 2022/23 at the College of Horticulture, Odisha University of Agriculture and Technology, Chiplima, Odisha to record the seasonal incidence of major insect pests with the predatory fauna on toria (Brassica rapa) in relation to meteorological parameters. The occurring pest complex in both seasons constituted a total nine number of insects and three consistent predatory fauna.The highest peak population of pests recorded for 2021/22 were: mustard aphid (3.7 A.I plant-1 at 50th SMW), whitefly (25.9 whiteflies plant-1 at 50th SMW), painted bug (13.37 nymphs+adults plant-1 at 50th SMW), mustard sawfly (12 larvae plant-1 at 48th SMW), flea beetle (12.45 grubs+adults plant-1 at 50th SMW), diamondback moth (1.3 larvae plant-1 at 52nd SMW), leaf Webber (6.45 larvae plant-1 at 51st SMW), Bihar hairy caterpillar (29.3 larvae plant-1 at 50th SMW) and tobacco caterpillar (8.9 larvae plant-1 at 49th SMW. Similarly, the highest peak population of pests recorded for 2022/23 were: mustard aphid (3.82 A.I plant-1 at 51st SMW), whitefly (23.8 whiteflies plant-1 at 50th SMW), painted bug (13.7 nymphs+adults plant-1 at 51st SMW), mustard sawfly (15 larvae plant-1 at 48th SMW), flea beetle (13.45 grubs+adults plant-1 at 50th SMW), diamondback moth (1.2 larvae plant-1 at 47th SMW), leaf Webber (5.45 larvae plant-1 at 51st SMW) which coincided the abundance of natural enemies namely, coccinellid predators, syrphid fly and spider between 50th to 52nd SMW of the experimental year for both seasons.The correlation of insect pest density with weather parameters (Rabi, 2021/22) showed negative correlations with Tmax (mustard aphid, painted bug, flea beetle, leaf Webber, diamondback moth, Bihar hairy caterpillar), Tmin (all pests), rainfall (mustard aphid, whitefly, mustard sawfly, flea beetle, tobacco caterpillar), RH% at 7 hours (all pests), and RH% at 14 hours (mustard aphid, whitefly, painted bug, leaf Webber, diamondback moth, Bihar hairy caterpillar).For natural enemies, Tmax, Tmin, RH% at 7 hours, RH% at 14 hours, and wind velocity had negative effects on their population, while rainfall had a positive influence. However, in Rabi 2022/23, Tmax, Tmin, and RH% at 14 hours negatively influenced the pest population mostly except for wind velocity and RH% at 7 hours. For predators, wind velocity showed positive correlation with its’ population.
ABSTRACT
A field experiment was conducted during Rabi season of 2022 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P.) India. To study the Response of Sulphur and Spacing on growth and yield of Toria. The treatments consist of Sulphur 15, 30, 45 kg/ha and Spacing 20×15, 20×20, 25×20 cm. There were 10 treatments each replicated thrice. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction pH (7.2) with EC-0.187 (dS/m), low in organic carbon (0.72%) available N (178.48 kg/ha), available P (27.80 kg/ha) and available K (233.24 kg/ha). Results revealed that the higher plant height (105.93 cm), higher plant dry weight (17.70 g), higher crop growth rate (13.8 g/m2/day), higher number of siliquae/plant (216.19), higher seeds/ siliquae (23.67), higher test weight (3.64 g), higher seed yield (1.76 kg/ha), higher stover yield (3.21 kg/ha) and higher harvest index (35.39%) were significantly influenced with application of Sulphur 45 kg/ha + Spacing 25×20 cm.
ABSTRACT
A field experiment was carried out at Regional Research and Technology Transfer Station (OUAT), Semiliguda of Koraput district under Eastern Ghat High Land zone of Odisha in acidic soil during two consecutive rabi seasons of 2016-17 and 2017-18 to study the residual effect of integrated nutrient management in maize on succeeding toria crop. The experiment was laid out in randomized block design with three replications consisting of twelve treatments. The present investigation revealed that application of soil test based fertilizer with green leaf manure (cowpea), FYM @ 5 t ha-1 and biofertilizer (Azotobacter + Azospirillum + PSB @ 4 kg ha-1 each) to maize crop registered maximum residual effect thereby resulted significantly highest seed yield (6.3 q ha-1) and stover yield (11.1 q ha-1) of toria with a net monetary return of Rs. 7025 ha-1 and benefit cost ratio of 1.38.
ABSTRACT
Introducción: Durante la pandemia por SARS-CoV-2, la cánula nasal de alto flujo (CNAF) se usó como soporte en espera de Unidad de terapia intensiva (UTI) o como alternativa a la ventilación invasiva. Objetivos: Primario: Determinar si la cánula nasal de alto flujo evita la intubación oro traqueal. Secundarios: Analizar predictores de éxito al inicio de la cánula nasal de alto flujo y análisis descriptivo de la muestra. Materiales y métodos: Estudio observacional descriptivo retrospectivo. Se incluyeron pacientes mayores de 16 años positivos para SARS-CoV-2, atendidos en guardia y unidad de terapia intensiva, que utilizaron cánula nasal de alto flujo entre octubre de 2020 y marzo 2021. Se recolectaron datos en planillas individuales, analizadas por un profesional externo. Resultados: Se incluyeron en el trabajo 72 pacientes (de 16 a 88 años), 20 mujeres y 52 hombres. El 50 % de la muestra evitó la intubación orotraqueal. El IROX inicio grupo "éxito" vs. grupo "fracaso", p = 0,006. Comparación Irox 12 h grupo "éxito" vs. grupo "fracaso" p < 0,001. Comparación "tiempo desde ingreso a inicio de cánula nasal de alto flujo" grupo "éxito" vs. grupo "fracaso", p = 0,133. Comparación "Delta IROX" grupo "éxito" vs grupo "fracaso" p = 0,092. Conclusión: Se evitó la intubación orotraqueal en el 50 % de los casos. El IROX de inicio y el IROX a las 12 h del uso de cánula nasal de alto flujo fue estadísticamente significativo, lo que es un buen predictor del éxito en esta población. La fecha de inicio de síntomas y el uso de cánula nasal de alto flujo y el delta del IROX durante las pri meras 12 h no fue estadísticamente significativo para el éxito de la terapia. Estos datos son una herramienta útil con el objeto de generar protocolos de selección de pacientes para esta patología.
Introduction: During the SARS-CoV-2 pandemic, the high flow nasal cannula (HFNC) was used as support while waiting for the Intensive Care Unit (ICU) or as an alternative to invasive ventilation. The objective of this work is the description and analysis of the use of CNAF in our population. Objectives: Primary: Determine if HFNC prevents orotracheal intubation. Secondary: Analyze predictors of success at the start of CNAF and a descriptive analysis of the sample Materials and method: Retrospective descriptive observational study. Patients over 16 years of age positive for SARS-CoV-2, treated in Guard and ICU were included. who used CNAF between October 2020 and March 2021 Data was collected in individual forms, analyzed by an external professional. Results: The study included 72 patients (16 to 88 years old), 20 women and 52 men; 50 % of the sample avoided orotracheal intubation. Start IROX, group "success" vs. group "failure" p = 0.006. Comparison Irox.12 h group "success" vs. group "failure" p < 0.001. Comparison "Time from admission to start of CNAF" group "success" vs. group "failure" p = 0.133. Comparison "Delta IROX" group "success" vs. group "failure" p = 0.092. Conclusion: HFNC avoided orotracheal intubation in the 50 % of the cases. The initial IROX and the IROX 12 hours after the use of HFNC were statistically significant, which is a good predictor of success in this population. The date of onset of symptoms and the use of FNAF and IROX delta during the first 12 hours were not statistically significant for the success of the therapy. These data are a useful tool for generating patient selection protocols for this pathology.
