Review study showed that CTPTR-CTW and ZTDSR-ZTW (RRRW) record the highest seed bank (SB) of grasses, sedges and BLWs as total weeds, in general; and predominant weeds i.e., Echinochloa spp., Ammania baccifera, Commelina benghalensis and Digitaria sanguinalis, in particular. It also showed the higher species richness (DMg) and Shannon–Weaver (H’) indices. CTDSRCTW and CTDSR-ZTW (RRR) show the lowest WSB and at par with Shannon–Weaver (H’) index; further, lowest species richness (DMg) under CTDSR-CTW.

Soil organic carbon (SOC) and its fractions (labile and non-labile) including particulate organic carbon (POC) and its components [coarse POC and fine POC], light fraction organic carbon (LFOC), readily oxidizable organic carbon, dissolved organic carbon (DOC) are important for sustainability of any agricultural production system as they govern most of the soil properties, and hence soil quality and health.

Nutrient supply is the most limiting factor next to the water for crop production. Sustaining rice production has become a great challenge, particularly in areas where rice productivity declines in spite of following recommended nutrient management practices.

Understanding the process of soil organic carbon (SOC) sequestration and mineralization in aggregates is pertinent to mitigate climate change and minimize risks of soil degradation. The NT system increased the proportion of >2 mm aggregate fraction and reduced the proportion of 0.25 mm macro-aggregate fraction also significantly increased in the 0.00-0.5 m layer in NT system. However, those within the 2.00-0.25 mm aggregate fraction were significantly reduced in the 0.05-0.200 m layer under NT system.

This paper identifies possible climate change responses that address agricultural production at the plant, and farm, regional scales. Critical components required for the strategic assessment of adaptation capacity and anticipatory adaptive planning is identified and examples of adaptive strategies for a number of key agricultural sectors are provided.

Hydrodynamic cavitation is a technology for the conservation of soil and water and waste water treatment due to its simple reactor design and capacity in large‐ scale operation. When fluid’s local pressure reaches a level lower than the saturation vapour’s pressure at environment temperature, cavitation bubbles begin to grow and together with fluid flow are driven to the points with high pressure where they are quickly collapsed.
