“…Averaging over Nform, the values ranged from 23.5 to 8.3 kg grain per kg N-input in 2011 and from 33.2 to 12.2 kg grain per kg N-input in 2012. Calcium nitrate allowed obtaining higher AE values than urea, confirming previous studies (Guarda et al, 2004;Rahman, et al, 2005). The observed values of indices describing N-input efficiency helped explaining the yield and GPC results, especially with respect to wheatear year-to-year variations.…”

“…During the transitional phase to CA, the limited amount of crop residues, typical of such dry environments, requires N application rates not lower than 150 kg ha -1 ; as the accumulation of crop residues increases over time the N fertilisation demand could be likely lowered, as already demonstrated by the available limited data (Rahman et al, 2005), thanks to the recycling of organic C and to long term effects on soil chemical, physical and biological properties.…”

Nitrogen (N) nutrition plays a key role for high yields and quality in durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn); in Mediterranean environments, data regarding N fertilisation management during the transition phase to conservation agriculture (CA) are limited. The aim of this work was to study the effects of N fertiliser forms and rates on yield and some quality traits of durum wheat, during the transition period to CA in Mediterranean areas; moreover, indication on the recommendable N form/rate combinations have been given. Field trials were carried out in south of Italy, during the first two years of transition to CA (from 2010 to 2012) in a durum wheat-based rotation. Following a split-plot design arranged on a randomised complete blocks with three replications, two N forms (main plots) -urea and calcium nitrate -and four N rates (sub-plots) -50, 100, 150 and 200 kg N ha -1 -plus an un-fertilised Control, were compared. The following parameters were analysed: grain yield, N-input efficiency, grains protein concentration (GPC), total gluten, gluten fractions and minerals concentration in kernels. Calcium nitrate gave the highest yield (4.48 t ha -1 ), as predicted by the quadratic model, at 146 kg N ha -1 , on average. This was particularly noticeable in 2012, when the distribution of rainfall and temperatures regimes as well as residues' status could have favoured such N-form. These results were confirmed by the observed higher values of all indices describing N-input efficiency. High GPC values (14.8%) were predicted at slightly higher N-rates (173 kg N ha -1 , averaging both N forms). In particular, gluten proteins and glutenin/gliadin ratio accrued as the N doses increased, reaching the highest values at 150 kg N ha -1 , also positively affecting the quality of durum wheat flour. Iron and zinc concentrations were noticeably increased (38% and 37% on average) by N supply, probably due to the enhanced water use efficiency under CA systems.Principal component analysis summarised properly the obtained results: analysing the N-rates at 150 kg N ha -1 , it was confirmed that yields and quality characteristics of durum wheat were optimised in the wettest year (2011) with calcium nitrate. Moreover, the scarce amount of residues characterising the transition phase to CA, requires N application rates not lower than 150 kg ha -1 in order to ensure stable yields and important quality traits. These N rates should be modulated as the accumulation of crop residues increases over time, thanks to long-term effects of CA on soil chemical, physical and biological properties. IntroductionSouthern Europe's environment is characterised by cool and wet winters and hot and dry summers with low and erratic rainfall distribution, and by soils with very low organic matter levels and nitrogen (N) content. Nitrogen is subjected to several losses with the main pathways being represented by ammonia volatilisation, denitrification and nitrate leaching (Plaza-Bonil et al., 2014). Moreover, in these environments ...

“…Reducing fertilizer N contact with the straw by drilling the fertilizer below the soil surface (about 5 cm beside and/or below the seed row) to minimize immobilization and volatilization may increase N use efficiency in wheat. Rahman et al (2005) observed a significantly larger apparent recovery of fertilizer N under mulch than non mulch conditions possibly due to reduction in fertilizer N losses. The build up of soil organic matter and increase in readily mineralized organic soil N with residue recycling suggest the potential for reducing fertilizer N rates for optimal yield of following crop after several years of residue incorporation (Eagle et al 2001, Thuy et al 2008, Yadvinder-Singh et al, 2009.…”

Rice-wheat (RW) cropping system of the Indo-Gangetic Plains has played a significant role in the food security of India. However, sustainability of this important cropping system is at risk due to the deterioration of soil health, mounting pressure on natural resources and emerging challenges of climate change. Conservation agriculture involving zero-or minimum-tillage and innovations in crop residue management (CRM) to avoid straw burning should assist in achieving sustainable productivity and allow farmers to reduce nutrient and water inputs, and reduce risk due to climate change. High yields of the irrigated RW system have resulted in production of huge quantities of crop residues (CRs). Burning of rice straw is common in north-western parts of India causing nutrient losses, and serious air quality problems affecting human health and safety. Mulch is a good option for rice residue management during the wheat crop, especially with no tillage. Mulch can increase yield, water use efficiency, and profitability, while decreasing weed pressure. Surplus residue from the previous wheat crop can be incorporated into the paddy fields with no adverse effect on rice yield. Residue decomposition in anaerobic flooded soil substantially increases methane emission relative to residue removal. Long-term studies of the residue recycling have indicated improvements in physical, chemical and biological health of soil. Since CRs contain significant quantities of plant nutrients; their continuous application will have positive effect on fertilizer management in RW system. Other plausible option of CRM lies in utilizing a potion of surplus residue for producing biochar (and co-production of bioenegy) for using as soil amendment to improve soil health, increase nutrient use efficiency and minimize air pollution. In this review authors have discussed current concerns and possible options for with efficient management of CRs in the RW cropping system.

The effects of conservation agriculture (CA) practices on soil properties along with crop yields of rice-based triple cropping systems have not been adequately assessed in Bangladesh. An experiment was conducted at Bangladesh Agricultural Research Institute, Gazipur, Bangladesh from 2009 to 2012 to assess the effects of tillage practices and crop residue retention on soil physical properties, soil organic carbon (SOC) and crop yields in a wheat-mungbeanrice system. Treatments consisted of three tillage practices (MT: minimum tillage; CT: conventional tillage and DT: deep tillage) and eight levels of crop residue management (S 0 -no residues retention, S r -retention of 30 cm rice straw, S m -whole mungbean stover retention, S W -30 cm wheat straw retention, S mr -whole mungbean stover & 30 cm rice straw retention, S rw -30 cm rice & wheat straw retention, S mw -whole mungbean stover & 30 cm wheat straw retention and S wrm -30 cm wheat and rice straw along with whole mungbean stover retention) were applied in split plot design with three replications. Bulk density (BD) and porosity responded positively to MT and increased residue retention of all crops (p > 0.05). Minimum tillage and S wrm also significantly accumulated SOC (p < 0.05; 0.38% higher than DT with no residue retention) and retained soil moisture (p < 0.05). Minimum tillage practice performed better in upland crops (p < 0.05; wheat & mungbean yields) and CT outperformed MT in wetland rice crop (p < 0.05). The grain and straw yields of wheat and rice were also influenced by previous crop residue retentions (p < 0.05). The results, therefore, suggested that increased residue 2 retention with minimum tillage practices improved soil properties and yield of upland crops but with deeper tillage practices consistently maintained wetland rice production.
