“…Mungbean residue incorporated treatments produced significantly higher yield than the rest residue treatments except DSR+BM-ZTW+RR treatment. Dhiman et al (2000) also reported similar findings. Lowest yield was recorded under the treatment (DSR-ZTW) where no-residue was applied during both the seasons.…”

The field experiments were conducted during rainy season (June to October) and winter season (November to April) of 2010−11 and 2011−12 at the research farm of Indian Agricultural Research Institute, New Delhi to assess the effect of tillage and residue management practices on yields and nurient uptake by crops in rice –wheat cropping system. Direct seeding under unpuddled condition, transplanting under puddled condition, brown manuring and mungbean residue incorporation before sowing of direct-seeded rice were practiced in rice, while zero-till sowing, conventional till sowing and rice residue application with zero-till wheat were tested in wheat crop. During first year nutrient uptake under transplanted rice was significantly higher than the rest of the treatments. In second year, treatments where rice residue was applied in previous season wheat crop and mungbean residue incorporation showed comparable N, P and K uptake with the TPR treatments. In case of wheat the uptake of nutrients were not significantly influenced during first year of study but in second year, the treatments where rice residue was applied with zero-till wheat and mungbean residue was incorporated in previous DSR showed significantly higher N, P and K uptake. In first year of study TPR produced significantly higher yield (5.37 t ha-1) while in second year mungbean residue incorporation with direct seeded rice produced significantly at par yield (5.61 t ha-1) than the transplanted rice (5.75 t ha-1). Productivity of wheat under all the treatments during first year remained at par but in second year MBR+DSR-ZTW+RR-MB produced significantly highest yield (5.33 t ha-1).

“…Poor root development caused by the previous rice crop's puddling was the key factor in the reduced grain yield of wheat following CT-PTR [34,35,36]. Similar to this, [37,38] contrasted the productivity of the DSR-based cropping system and the PTRbased cropping system. He noted that the productivities of the DSR-wheat, DSR-chickpea, and DSR-mustard systems were greater than those of the PTR systems (13.53 t/ha, 12.12 t/ha, and 11.81 t/ha, respectively).…”

Climate change is a major issue facing humanity, and the most common method for growing rice is manual puddled transplanted rice (PTR). Direct-seeded rice (DSR) is becoming increasingly popular due to its reduced methane emissions and reduced labour costs. However, there are drawbacks to this transition, such as an increase in weeds, herbicide resistance, nitrous oxide emissions, nutritional disorders, and soil-borne diseases. To reduce these issues, appropriate weed, water, and fertilizer management practices should be applied. Chemical and biotechnological methods, such as herbicide-resistant and more competitive allelopathic variants, will be required for sustainable rice production. The development of site- and soil-specific integrated packages will increase the adoption of DSR and decrease the negative effects of PTR on the environment.

“…(2016) reported that younger seedlings with higher tillering ability, optimum plant population, efficient nutrient, and moisture utilization enabled SRI to produce higher grain yield. Higher grain yield in DSR was due to early seeding vigor, avoidance of transplanting shock, increased panicle number, higher test weight, and reduced poor grain sterility percentage ( Gangwar et al., 2008 ). Compared to continuous flooding, AWD considerably reduced water use while maintaining or even increasing yields ( Mishra and Salokhe, 2011 ; Thakur et al., 2014 ; Malyan et al., 2016 ).…”

Multi-criteria assessment to screen climate smart rice establishment techniques in coastal rice production system of India

IntroductionConventional rice production techniques are less economical and more vulnerable to sustainable utilization of farm resources as well as significantly contributed GHGs to atmosphere.MethodsIn order to assess the best rice production system for coastal areas, six rice production techniques were evaluated, including SRI-AWD (system of rice intensification with alternate wetting and drying (AWD)), DSR-CF (direct seeded rice with continuous flooding (CF)), DSR-AWD (direct seeded rice with AWD), TPR-CF (transplanted rice with CF), TPR-AWD (transplanted rice with AWD), and FPR-CF (farmer practice with CF). The performance of these technologies was assessed using indicators such as rice productivity, energy balance, GWP (global warming potential), soil health indicators, and profitability. Finally, using these indicators, a climate smartness index (CSI) was calculated.Results and discussionRice grown with SRI-AWD method had 54.8 % higher CSI over FPR-CF, and also give 24.5 to 28.3% higher CSI for DSR and TPR as well. There evaluations based on the climate smartness index can provide cleaner and more sustainable rice production and can be used as guiding principle for policy makers.
