“…After that, MgO powder and Devarda's alloy were added to the aliquot and placed in the distillation unit. The N content was determined by titrating with 0.01 N H 2 SO 4 till a slight purple colour developed as end point (Nayak et al 2016). Potentially mineralizable nitrogen (N 0 ) (day − 1 ) and N mineralization rate constant (kN) (kg ha − 1 day − 1 ) were measured using the rst order kinetics (Eq.…”

Continuous monocropping of puddled rice in Eastern India has decreased crop productivity and contributed to the deterioration of soil structure. To address this issue, conservation agriculture (CA) is being developed as a method to promote sustainability of the rice-based cropping system in eastern India. The study was conducted with the objectives to evaluate the influence of CA components on C and N mineralization and to study the impact of CA on the soil enzymes, C and N fractions. At the research farm of ICAR National Bureau of Plant Genetic Resources, Cuttack, a study was conducted using components of conservation agriculture in different combinations. The study included the effects of different components of CA, such as reduced tillage (T), addition of crop residues (R), and crop diversification (D) both alone and in combinations. Standard methods were used to determine carbon (C) and nitrogen (N) fractions, mineralization, and soil enzyme activities. Results showed that the addition of residue and crop diversification components (crop residues, crop residues with reduced tillage, crop residues with diversification and crop residues with reduced tillage and diversification) had higher CO2-C levels. Carbon mineralization in terms of mean cumulative CO2-C (mg CO2-C kg-1) fit well with first-order kinetics (R2=0.97-0.99), suggesting that degradation is concentration-dependent. Potentially mineralizable N (N0) content ranged from 191.27 to 219.53 kg ha-1, with the highest value in diversification (D). It showed the highest dehydrogenase activity and nitrate reductase activity, while residue addition in rice-green gram system (RD) showed the highest fluorescein di-acetate and β-glucosidase activities. At all growth stages, diversification (D) had the highest values for microbial biomass C, ammonium N and nitrate N. Correlation study shows a positive interaction between carbon and nitrogen fractions with soil enzymatic activities. It can be concluded that the influence of crop diversification (component D) and residue addition (component R) were more effective in C and N mineralization, fractions and soil enzyme activities than the other component of CA. The beneficial effect of incorporating residues is even more effective when it is combined with crop diversification. The combination of some of the components of CA are as good as complete CA in C and N mineralization, fractions and soil enzyme activities for rice-green gram cropping system.

“…Previous studies have called attention to the unintended negative impacts of the production of food grains on India's food system. They have highlighted the high dependency of cereal consumption on production in states with stressed groundwater reserves (Kayatz et al 2019, Harris et al 2020, Rajan et al 2020 and rising greenhouse gas (GHG) emissions from agriculture (Rao et al 2019, Nayak et al 2023. Some studies have proposed solutions such as reducing groundwater use by removing power subsidies for agriculture (Bhattarai et al 2021); providing incentives for water conservation (Shah 2009, Fishman et al 2015; replacing rice production with alternate grains (Davis et al 2018(Davis et al , 2019; and adopting sustainable agricultural practices to mitigate GHG emissions (Sapkota et al 2019).…”

Reducing the true cost of food-based safety nets: evidence from India’s subsidized food program

Public procurement of food plays a pivotal role in determining the production and consumption of various food items. This is particularly true for staple grains in countries such as India, where the government procures over 40 percent of rice and wheat. This grain is redistributed to approximately 60 percent of India’s population through the Public Distribution System (PDS), the national food-based safety net. Although the PDS plays a critical role in ensuring food security for millions of beneficiaries, there is scope for reducing the hidden costs associated with the production of PDS food grain. As costs such as unsustainable use of groundwater and subsidies for power and fertilizers are not accounted for in the ‘financial’ cost of the program, we use true cost accounting (TCA) to identify, quantify, and monetize these hidden costs associated with the PDS. In 2021-22, the Indian government and PDS beneficiaries spent US$16.5 billion and US$0.9 billion, respectively, on the PDS. However, accounting for hidden costs associated with the production of PDS food grain reveals that the true cost of the PDS is more than twice its financial cost. Using true cost estimates of distributing rice, wheat, and millets through the PDS, we find that replacing one kg of rice with one kg of millets for a quarter of PDS beneficiaries every month has the potential to reduce the true cost of the PDS by US$1.37 billion annually.
