Soil salinity is a major threat to the sustainability of agricultural production and rural livelihoods in the Mirzachul area in Uzbekistan. Leaching, a traditional practice to cope with salinity through flushing of soils with fresh water in order to remove excess salts from the topsoil, is no longer feasible due to disrepair and inefficient operation of the drainage networks. As a result, salinized lands are either giving very low yields and income or are abandoned, which is negatively affecting rural livelihoods. As an intermediate solution, the cultivation of licorice (Glycyrrhiza glabra) is proposed as a viable alternative, as it rehabilitates salinized soils and improves their fertility - so that major crops can be again grown profitably in these abandoned or highly saline lands. In addition to its positive impact on the sustainability of agricultural production in irrigated areas, licorice cultivation can also increase farm income thanks to the high economic value and marketability of its roots and the value of its biomass as livestock feed.
To cultivate field crops and increasing their salinity resistance under saline soil condition has become the prior issue. It is important to study the technology of care for each field crop based on the specific soil and climatic conditions. It is very essential to study the advanced technologies to increase the salinity of corn in these soils. In the condition of less saline soils, the green mass of the produced corn was 669.9 c/ha and dry mass constituted 169.6 c/ha while was in average saline soil this indicates were 312.7 c/ha and 95.00 c/ha relatively. Under strong saline soil condition initially 3-4 pieces of corn sprouted per sq. m. and subsequently died of salt exposure. KEYWORDS: corn, less saline, medium saline, salt resistance, sowing time, dense of seedling, green mass, irrigation dynamics.
This article discusses how to develop students' skills in physics lessons and how to choose problems. Preschool educational institutions and schools are responsible for the education of students with modern scientific and technical knowledge and understanding, providing quality education and the first lessons in the harmonious development of young people, the proper development of children's worldview.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
