COVID-19, Government Transfer Payments, and Investment Decisions in Farming Business: Evidence from Northern India.

Although the COVID-19 pandemic resulted in about a 24% decline in India's GDP during the April-June 2020 quarter, the nation's agricultural sector, somewhat surprisingly, seems to have done remarkably well. This paper examines whether the public transfer program Pradhan Mantri Garib Kalyan Yojana (PMGKY), announced immediately after the lockdown, benefited farmers in dealing with the COVID shock. Overall, 95% of the smallholders received support from at least one of PMGKY's four components. Direct cash transfers had significantly more impact than in-kind transfer schemes. The result shows that farmers receiving cash transfers under PM-KISAN, one component of PMGKY, were more likely to invest in buying seeds. In contrast, farmers receiving cash transfers under PM-UY, another piece of PMGKY, were more likely to invest in fertilizer and pesticides. Finally, smallholders who received benefits from all four components of PMGKY were more likely to invest in purchasing seeds, fertilizer, and pesticides. Findings suggest the fungibility of public cash transfers from the recent PMGKY scheme is significant in alleviating credit constraints and increasing future investments in modern inputs.

India's COVID-19 social assistance package and its impact on the agriculture sector.

Context: CVOID-19 induced significant economic and social disruptions in India. Rural households, including smallholders, were affected by loss in migrant income, livelihood and farm and non-farm incomes. During this lockdown, the Indian government enacted several emergency legislations to provide direct and indirect relief to workers and households. India's COVID-19 social assistance package, namely, PM-GKY, announced in March 2020, was designed to provide immediate relief to the vulnerable population. The PM-GKY provided cash direct benefit transfers (DBT) and in-kind supports (IKS) through existing schemes. Objectives: This study examines the impact of India's government assistance package (known as Pradhan Mantri Garib Kalyan Yojana or PM-GKY), announced immediately after the COVID-19 lockdown, on the procurement of agricultural inputs for the upcoming farming season. Methods: The study uses a quasi-experimental method and survey data from 1,789 smallholder households in three northern Indian states (Rajasthan, Madhya Pradesh, and Uttar Pradesh). Results: The result suggests that the fungibility of funds received under the government transfer package was significant in alleviating credit constraints and increasing agricultural investments in agricultural inputs. The farmers who received benefits from the PM-GKY scheme spent significantly more on the procurement of seeds, fertilizers, and pesticides. Conclusions: The disbursement of cash transfers in the three states showed that emergency relief packages had reached the vulnerable sections of Indian society. Overall, 89-94% of households benefited from direct cash transfers. Perhaps lower transaction costs, minimal leakages, and immediate delivery make a strong case for direct cash transfers. The above advantages facilitate the provision of relief to a large proportion of vulnerable sections of Indian society in a short period.

Impact of COVID-19 on agricultural markets: assessing the roles of commodity characteristics, disease caseload and market reforms.

This paper assesses the impact of the spread of COVID-19 and the lockdown on wholesale prices and quantities traded in agricultural markets. We compare whether these impacts differ across non-perishable (wheat) and perishable commodities (tomato and onion), and the extent to which any adverse impacts are mitigated by the adoption of a greater number of agricultural market reform measures. We use a granular data set comprising daily observations for 3 months from nearly 1000 markets across five states and use a double- and triple- difference estimation strategy. Expectedly, our results differ by type of commodity and period of analysis. While all prices spiked initially in April, they recovered relatively quickly, underscoring the importance of time duration for analysis. Wheat prices were anchored in large part by the minimum support price, while tomato prices were lower in some months. Supply constraints began easing in May with greater market arrivals perhaps reflecting distress sales. Market reform measures did help in insulating farmers from lower prices, but these effects are salient for the perishable goods, and not so much for wheat where the government remained the dominant market player. Taken together, these results point to considerable resilience in agricultural markets in dealing with the COVID-19 shock, buffered by adequate policy support.

Ultrananocrystalline diamond-decorated silicon nanowire field emitters.

Silicon nanowires (SiNWs) were uniformly decorated with ultrananocrystalline diamond (UNCD) by a novel route using paraffin wax as the seeding source, which is more efficient in the creation of diamond nuclei than traditional methods. These one-dimensional ultrananocrystalline diamond-decorated SiNWs (UNCD/SiNWs) exhibit uniform diameters ranging from 100 to 200 nm with a bulbous catalytic tip of ∼250 nm in diameter and an UNCD grain size of ∼5 nm. UNCD/SiNW nanostructures demonstrated enhanced electron field emission (EFE) properties with a turn-on field of about 3.7 V/µm. Current densities around 2 mA/cm(2) were achieved at 25 V/µm, which is significantly enhanced as compared to bare SiNWs.

Single-step route to diamond-nanotube composite.

Candle wax was used as a precursor for the production of a diamond-nanotube composite in a single step. The composite films were fabricated by sulfur-assisted hot-filament chemical vapor deposition technique. The morphology of the composite films was analyzed by scanning electron microscopy and transmission electron microscopy. Raman spectra of the films show characteristic diamond band at 1,332 cm-1, D-band around 1,342 cm-1, and graphitic G-band around 1,582 cm-1. The electron energy-loss spectroscopy recorded at the carbon K-edge region shows signature features of diamond and carbon nanotube in the fabricated material. The ability to synthesize diamond-nanotube composites at relatively low temperatures by a single-step process opens up new possibilities for the fabrication of nanoelectronic devices.

Fabrication and field emission study of novel rod-shaped diamond-like carbon nanostructures.

Novel sp(3) rich diamond-like carbon nanorod films were fabricated by a hot filament chemical vapour deposition technique. The results are indicative of a bottom-up synthesis process, which results in a hierarchical structure that consists of microscale papillae comprising numerous nanorods. The papillae have diameters ranging from 2 to 4 microm and the nanorods have diameters in the 35-45 nm range. A growth mechanism based on the vapour-liquid-solid mechanism is proposed that accounts for the morphological aspects at the microscale and nanoscale. Investigation of field emission properties of fabricated nanorods reveals a low turn-on field of about 4.9 V microm( - 1) at 1 nA and a high field-enhancement factor.
