Excessive use of synthetic chemicals in conventional agriculture largely degraded the agroecosystems that constitute approximately 40% of the global terrestrial ecosystems. Moreover, changing climate resulted in a substantial loss in agricultural productivity (both in quantity and in quality) mainly due to diverse abiotic and biotic stresses. This draws public awareness about depleting natural resources, viz., soil, land, and water due to unsustainable agricultural practices and equivalently concerns for food-related animal and human health risks. Modern organic agriculture has shown positive impacts in terms of food/biomass production, climate resilience, soil health, biodiversity, nutritional security, and good quality of life; and is of prodigious demand for nutrient-rich organic food products. In the ensuing decade, owing to the principal focus for the quality aspects or health benefits of organic agriculture, this review explores how organic interventions affect the nutritional value and yield quality in a production system; enable plants to adapt to adverse futuristic environmental conditions, and address the global food and nutritional security challenges. The chronological emergence, current global status, public perceptions, and key components of organic agriculture with their attached health benefits are inextricably synthesized herein. Fostering the ethos of organic agriculture under the UN Decade on Ecosystem Restoration (2021-2030) is highly imperative for agroecosystem restoration and its sustainable management. Moreover, the multidimensional paybacks of organic agriculture help in attaining important global goals and targets such as the Bonn Challenge and United Nations Sustainable Development Goals (UN-SDGs) by the year 2030. Therefore, invigorating the escalation of organic farming as a concurrent strategy of soil, land, and ecosystem restoration is the need of the hour.

Effects of different levels of chemical fertilizer, farmyard manure (FYM) and bio-inoculants on nutrient content, uptake and quality parameter of wheat were studied. Results indicated that increasing levels of chemical fertilizer, FYM and bio-inoculants significantly enhanced nutrient content and uptake by wheat, while quality parameters of wheat showed significant results with bio-inoculants application. Maximum N, P and K content and their uptake in grain (80.3, 11.07 and 25.29%, respectively) and straw (32.18, 7.14 and 95.92%, respectively) were noticed with 100% NPK over control. Application of FYM @ 10 t/ha significantly increased nutrient content (NPK) in grain and straw and their uptake over the control. The total N, P and K uptake by wheat were found to be maximum 80.97, 12.68 and 86.10 kg/ha, respectively with the application of FYM over control. Combined use of fertilizer levels and FYM, and combined use of fertilizer levels and bio-inoculants significantly increased the nutrient uptake by wheat. Bangladesh J.
