“…The beneficial effect of crop residue retention is attributable to better temperature modulation and crop protection from heat stress (Choudhary et al 2018). Residue retention improves the soil water holding capacity by increasing the soil organic carbon in loam or silt loam soils, which partly explains the difference in the effect of conservation agriculture and conventional practices (Paul et al 2014). Soil water content-higher under conservation agriculture practices-may play a key role in sustaining soil function during short-term dry periods (Liu et al 2014).…”

This study compares the economic impacts of conservation agriculture and conventional farming systems in the Lower Gangetic alluvial tract of West Bengal, India. Under conservation agriculture the overall gain in system productivity is 2.40%. The estimated change is attributable to the relative change in input use. Technology had a minor effect on the change in crop productivity, and the reduced use of machine labour, bullock labour, and plant protection chemicals had a significant positive impact. Farms that practised conservation agriculture averaged a 12.88% higher return per rupee of investment than conventional farm families.

“…Sustainable farming involves alternative integrated crop management approaches that are environment‐friendly 9 . Proficient agricultural management approaches involve tillage, crop rotation, soil water management, nutrient management, use of animal manures and legumes, soil cover maintenance, crop residue management, and crop diversification, for efficient crop production and soil health 10,11 . The conventional agricultural practice includes heavy tillage that limits the recycling of organic material and accelerates soil erosion, thereby enhancing the requirement of synthetic chemicals and mineral fertilizers to meet the need for nutrients 12 .…”

BACKGROUND Modern agricultural management approaches are often dependent on the application of chemicals, resulting in adverse impacts on human and environmental health. Therefore, for sustainable agriculture, there is a need to implement integrated agriculture practices that can maintain natural soil microbiome and enhance crop production. Various agricultural approaches influence crop production by impacting the functional bacterial community entailed in biogeochemical cycles, for example, nitrogen (N) cycle. This study aimed to assess the rhizospheric N cycling community of soybean under three agricultural practices, namely, conservation agriculture (CA), conventional treatment (CT), and organic agriculture (OA) for two consecutive years (2017 and 2018). RESULTS A field experiment was designed under soybean–wheat cropping system employing CA, CT, and OA modules that included different practices of tillage, crop bedding pattern, crop residue retention, and nutrient application. Assessment of bacterial communities contributing to N transformation was performed with quantitative polymerase chain reaction (qPCR) of important markers (nifH, amoA, narG, and nirK). CONCLUSION Results concluded that the practice of conservation agriculture comprising of raised bed, zero tillage, crop residue retention, and application of NPK (nitrogen, phosphorus, potassium) nutrients favorably affected the plant attributes and the abundance of N cycling bacterial community over the two consecutive years. The outcome revealed the mechanistic principle behind enhanced plant growth under conservation agriculture, and opened up the possibility of regulating the N cycling bacterial community to develop sustainable and productive agro‐ecosystems. © 2020 Society of Chemical Industry

“…However, micronutrient deficiencies were subsequently noticed in many parts of the world with the introduction of high yielding varieties (HYVs) [1]. Such micronutrient shortages were due to the high yield capacity and high nutritional needs of these high yielding genotypes, which resulted in improper usage of high analytical fertilizers, no introduction of organic manures, imbalanced fertilization, etc [2]. These micronutrients are not only essential to plants, but help in sustaining human as well as animal health.…”

Earlier, the agriculture system was oriented more towards achieving higher agronomic yields than the nutritional quality of food. Green revolution significantly enhanced the crop production primarily rice, wheat and maize production was boosted to meet the energy needs of growing population. As a consequence of the predominance of cereal-based staples that are fundamentally low in micronutrients, specifically Zn and Fe, more than 2 billion people worldwide suffer from an insidious type of deficiency known as micronutrient malnutrition. Just moderate amounts of micronutrient malnutrition can affect cognitive development, reduce disease resistance and increase the risk of women dying during childbirth. The approach to micronutrient fertilization has been shown to improve the yield and nutritional content of the staples. Agronomic biofortification provides an immediate and effective method to enhance accumulation of micronutrients especially Zn and Fe in cereals. An adequate amount of plant available micronutrients is a prime requisite to ensure adequate nutrient uptake. Most of the cereals are grown in soils deficit in Zn and under reduced conditions of rice ecosystem, its availability is decreased due to formation of less soluble Zn complexes with sulphate and carbonate. The form of fertilizer used, timing and method of application is critical for the enhancement of the grain quality of Zn and Fe. The effectiveness of agronomic biofortification can be enhanced by application of synthetic chelated micronutrient fertilizers and/or organic fertilizers fortified with micronutrients in combination with NPK ensuring proper nourishment of crops with adequate nutrient supply by slow release of nutrients in soil solution. Further, the response of foliar application has shown better results than soil application. Previous studies suggest that Zn fertilization not only enhances Zn concentration in grain but also improves the overall performance of maize crop. Agronomic biofortification of crops is advantageous in terms of accessibility, rapid result, ease in application and high sustainability.
