Abstract: Declining land productivity associated with diminishing farm size is a significant issue for intensive and sustainable crop production in Ethiopia. An intercropping of cereals such as wheat with grain legumes may provide a farm wide production system that achieves both economic and environmental concerns. Therefore, a field trial was carried out to evaluate the effect of different crop combinations of wheat-haricot bean on the productivity of wheat and haricot bean under two tillage practices at Alem Tena during 2016-2017 cropping seasons. The experiment was conducted by using split-plot design with three replications. The treatments comprised of two tillage practices (conventional and minimum tillage) assigned as the main plot and five wheat-haricot bean intercropping combinations (1:0, 1:1, 2:1, 1:2 and 0:1) assigned as the subplot. The results showed that tillage practices had a significant effect on growth and yield parameters of wheat, but not on growth and yield parameters of haricot bean. Minimum tillage increased biomass and grain yield of wheat over conventional tillage. Intercropping combination had a significant effect on both growth and yield parameters of both crops. The highest yield of wheat (3396 kg/ha) and haricot bean (4257.1 kg/ha) were observed in sole wheat and sole haricot bean, followed by 2:1 and 1:2 wheat-haricot bean combination, respectively. However, competitive indices showed that wheat-haricot bean in any of the combinations found to be more profitable and productive compared to sole wheat and haricot bean. Among intercropping combinations, 1:2 wheat-haricot bean gave the highest LER, ATER, MAI, IER. Therefore, 1:2 wheat-haricot bean intercropping combinations with a minimum tillage may provide a new opportunity in a low-input small grain production system for the study area, one that accomplishes both environmental and economic benefits through higher land productivity, improved grain and biomass productions.

Abstract: These days the world has been facing ever seen multi-dimensional crisis due to new deadly disease known as Covid-19. Even though world is not stranger for different catastrophic events recently the outbreak of Covid-19 came up with ever seen difficulties which tested the resilience of different societies. Covid-19 came to social world when the globalization era celebrates its hegemonic inevitabilities. So far different pandemic visited human society and none of them were not mysterious compared to Covid-19. Those pandemic were either partly or completely controlled by the then human knowledge and technologies. However, Covid-19 tested hitherto medical knowledge and health system of all societies regardless of their level of advancement. Yet different societies experienced Covid-19 challenges and pains differently. This trend may provoke the question of covid-19 varying factors and the overall nature of a given Society. Covid-19 deadly affected almost all societies regardless of their technological and medical advancement. So far Covid-19 distracts all elements of social systems such as social life, political life, cultural life, spiritual life, economic life and overall social existence. Different societies used to withstand covid-19 challenges with different affordable and relevant strategies. Different aspects of society have been affected. In this article, it is needed to penetrate into varying intensity secrets complicated the pandemic despite knowledge gap and limitation of medical knowledge in case of exhaustive awareness of etiology of viruses.
