RESUMEN
Dryland agricultural system is under threat due to climate extremes and unsustainable management. Understanding of climate change impact is important to design adaptation options for dry land agricultural systems. Thus, the present review was conducted with the objectives to identify gaps and suggest technology-based intervention that can support dry land farming under changing climate. Careful management of the available agricultural resources in the region is a current need, as it will play crucial role in the coming decades to ensure food security, reduce poverty, hunger, and malnutrition. Technology based regional collaborative interventions among Universities, Institutions, Growers, Companies etc. for water conservation, supplemental irrigation, foliar sprays, integrated nutrient management, resilient crops-based cropping systems, artificial intelligence, and precision agriculture (modeling and remote sensing) are needed to support agriculture of the region. Different process-based models have been used in different regions around the world to quantify the impacts of climate change at field, regional, and national scales to design management options for dryland cropping systems. Modeling include water and nutrient management, ideotype designing, modification in tillage practices, application of cover crops, insect, and disease management. However, diversification in the mixed and integrated crop and livestock farming system is needed to have profitable, sustainable business. The main focus in this work is to recommend different agro-adaptation measures to be part of policies for sustainable agricultural production systems in future.
RESUMEN
Maize flour was infested with fresh emerged Tribolium castaneum adults, and its nutritional composition was evaluated after 0, 45, and 90 days of the infestation. Furthermore, 99% carbon dioxide was applied to different developmental stages of T. castaneum for its management. There were six treatments and five replicates; for each replicate, maize flour (150 g) was taken in a 250-ml plastic jar container, insects were released in the flour, and jars were placed into the incubator at a temperature of 28 ± 1 °C, 60 ± 5% RH. Similarly, the application of 99% CO2 was done with four exposure times of 12, 24, 48, and 72 h, at 35 °C 65 ± 5% RH. Present results showed major fluctuations in the nutritive composition of maize flour. Increase in the moisture, fat, fiber, protein, and ash contents was directly proportional to the increase in infestation level and time, contrary to the depletion of carbohydrates and total weight loss. The results of CO2 treatment indicated that pupa was the most resilient stage as compared with larvae and adult stage. The observed susceptibility order was as follows: adult > larvae > pupae. The maximum mortality of adult, larval, and pupal stages was recorded after 24, 48, and 72 h of CO2 application, respectively. These findings might be helpful to develop an ecofriendly technique to manage this crucial pest.
