“…However, micronutrient status in the soils was not targeted in this study. Higher BD in RW cropping system might be due to low organic matter input and compaction by the heavy vehicles like tractors (Datta et al, 2015;Chaudhari et al, 2015a).…”

“…It has long been recognized that hydraulic conductivity is related to the grain size distribution of granular porous media (Bardhan et al, 2016). Since hydraulic conductivity can vary, depending on many indices, it is difficult to treat all these parameters at the same time (Chaudhari et al, 2010). It is now recognized that hydraulic characteristics can be obtained from direct and field measurements.…”

“…The water permeability of the soil, to a large extent, determines how efficient an irrigation or drainage system functions. The hydraulic conductivity is not an exclusive property of the soil alone, since it depends upon the attributes of soil and the fluid together (Chaudhari et al, 2010). The soil characteristics, which affect the hydraulic conductivity, are the total porosity, the distribution of pore sizes and tortuosity, in short the pore geometry of the soil (Bandyopadhyay et al, 2011;Chaudhari et al, 2015).…”

Three soil profiles from Regional Research Station of Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur situated in New Alluvial zone of Nadia district, West Bengal were studied to assess the predictability of the hydraulic conductivity of the soil as influenced by different physical and chemical and properties of cultivated and forest land. The various statistical procedures were employed on the measured laboratory based data for comprehensive agreement of dependent hydraulic conductivity of soils as a model function of independent soil variables that is likely to be useful for different land cover systems. Soils are neutral in reaction, silty clay to silty clay loam in nature. Forest soil contained greater organic carbon (OC)(5.9 ± 0.16 g kg ). Jhau plantation recorded the highest value (6.8 g kg -1) of OC due to soil texture and cation exchange capacity (CEC). Soil hydraulic conductivity was greater in soil for cabbage and Sagun tree among the cultivated and forest soil studied with values 2.80 and 1.10 cmh -1. Correlation study showed a positive and negative relation with hydraulic conductivity for sand (r= 0.68; P > 0.05) and clay (r= -0.71; P > 0.05) respectively. Further, principal component analysis concluded that addition of bulk density with clay and sand can predict the hydraulic conductivity for different land uses.

Rice ( Oryza sativa L.) is the staple food of more than 50% of the world’s population. Manual puddled transplanted rice (PTR) system is still the predominant method of rice establishment. However, due to declining water tables, increasing water scarcity, water, labor- and energy-intensive nature of PTR, high labor wages, adverse effects of puddling on soil health and succeeding crops, and high methane emissions, this production system is becoming less profitable. These factors trigger the need for an alternative crop establishment method. The direct-seeded rice (DSR) technique is gaining popularity because of its low input demand compared to PTR. It is done by sowing pre-germinated seeds in puddled soil (wet-DSR), standing water (water seeding), or dry seeding on a prepared seedbed (dry-DSR). DSR requires less water and labor (12–35%), reduces methane emissions (10–90%), improves soil physical properties, involves less drudgery and production cost (US$9–125 per hectare), and gives comparable yields. Upgraded short-duration and high-yielding varieties and efficient nutrient, weed, and resource management techniques encouraged the farmers to switch to DSR culture. However, several constraints are associated with this shift: more weeds, the emergence of weedy rice, herbicide resistance, nitrous oxide emissions, nutrient disorders, primarily N and micro-nutrients, and an increase in soil-borne pathogens lodging etc. These issues can be overcome if proper weed, water, and fertilizer management strategies are adopted. Techniques like stale bed technique, mulching, crop rotation, Sesbania co-culture, seed priming, pre-emergence and post-emergence spray, and a systematic weed monitoring program will help reduce weeds. Chemical to biotechnological methods like herbicide-resistant rice varieties and more competitive allelopathic varieties will be required for sustainable rice production. In addition, strategies like nitrification inhibitors and deep urea placement can be used to reduce N 2 O emissions. Developing site and soil-specific integrated packages will help in the broader adoption of DSR and reduce the environmental footprint of PTR. The present paper aims to identify the gaps and develop the best-bet agronomic practices and develop an integrated package of technologies for DSR, keeping in mind the advantages and constraints associated with DSR, and suggest some prospects. Eco-friendly, cost-effective DSR package offers sustainable rice production systems with fewer resources and low emissions. Graphical abstract
