The Impact

Frontline demonstration is the long-term educational activity conducted by agricultural scientists in a systematic manner on farmers’ field to show the worth of new practice/technology under the micro-farming situation. The Krishi Vigyan Kendra, Ratnagiri had conducted the frontline demonstrations (FLDs) on oilseeds during 2011 to 2016. The KVK had organized 93 FLDs on Groundnut (Arachis hypogaea) in two villages viz., Asage and Gawane and 26 FLDs on Niger (Guizotia abyssinica) in Gawane village from Lanja Block of Ratnagiri district. Therefore, the aim of present study was to determine the impact of frontline demonstrations (FLDs) on yield, adoption, varietal replacement of oilseed crops and its horizontal spread in Konkan region of Maharashtra state. To get the adequate size of the sample, 119 FLDs beneficiary farmers (93 Groundnut + 26 Niger) were selected as the sample for the present study. The study was conducted in experimental designs (Before-After and Control-Treatment) of social research. The findings showed that significant increase in the average yield of demonstration plot (20.57q ha-1) over the control plot (13.75 q ha-1) of groundnut crop. Average yield of niger was 2.75 q ha-1 , which increased to 3.11 q ha-1 in demonstration year. FLDs showed a positive impact on the adoption of production technologies in groundnut and niger. The ‘Local’ and ‘SB-11’ variety of groundnut were replaced by improved varieties such as ‘Konkan Trombay Tapora’, ‘TG 26’ and ‘Konkan Gaurav’. Similarly, improved ‘IGP-76’ and ‘Phule Karala’ varieties of niger replaced the ‘Local’ low yielding varieties. The area under improved varieties increased periodically. Thus, it can be inferred that FLD is an effective extension intervention to demonstrate the production potential of improved technologies in oilseed crops on farmers’ field. Therefore, it is recommended that the extension agencies engaged in transfer and application of agricultural technologies on farmer’s field should give priority to organize frontline demonstrations (FLDs) on cluster basis for harnessing the productivity potential of oilseed crops in the country.

The Impact

In our research we examined the effect of the hybrid, the nutrient supply, the number of plants and the abiotic factors (temperature, amount of precipitation) on the yield, crop quality and yield stability of maize. We devoted special attention to the natural nutrient utilization ability and fertilizer reaction of maize. The experiment took place in Hajdúszoboszló on chernozem soil, on a nearly 8 ha field. The size of one plot was 206 m2; therefore, this experiment was half-industrial. We tested six hybrids with different genetic characteristics and growing seasons. I analysed the correlation between the nutrient supply and the yield of maize hybrids with control treatment (treatment without fertilization) and with N 80, P2O5 60, K2O 70 kg ha-1 and N 160, P2O5 120, K2O 140 kg ha-1 fertilizer treatments. The yield increasing effect of the fertilizer also depended on the number of plants per hectare to a great extent. The number of plants of the six tested hybrids was 60, 70, and 80 thousand plants ha-1. In Hajdúszoboszló in 2017, up to October, 445.8 mm of rain fell, which is in line with the average values of 30 years, and is only 45.7 mm less than those. In 2017, the effect of increasing the plant number was slighter. Averaged over the observed fertilizer treatments and hybrids, the yield was 9.10 t ha-1 with 60 thousand plants ha-1, 9.11 t ha-1 with 70 thousand plants ha-1 and 9.12 t ha-1 with 80 thousand plants ha-1. Without fertilization, in most cases, increasing the plant number from 60 thousand plants ha-1 to 70-80 thousand plants ha-1 does not increased the yield but decreased it. With N80+PK treatment the yield changed between 8.90 and 11.27 t ha-1. The effect of increasing the plant number was just slightly observable and did not show a clear tendency. The effect of changing the plant number, even with the highest dosage of fertilizers, could not be detected adequately. In contrast with the plant number, the effect of the different fertilizer treatments was expressly traceable. Compared to the control treatment (treatment without fertilization), with N80+PK fertilizer dosage with 60 thousand plants ha-1 the yield increased by 3.36–4.99 t ha-1. The smallest demonstrable proof, i.e. the LSD5% was 0.22 t ha-1, which means that fertilization, in each case, significantly increased the yield. When analysing the effect of fertilization in the average of the hybrids and the different plant numbers, a yield of 5.61 t ha-1 could be detected, which value was 10.12 t ha-1 with N80+PK treatment and 11.61 t ha-1 with N160+PK treatment. Thus, it can be calculated that compared to the treatment without fertilization, the N80+PK treatment increased the yield by 4.51 t ha-1, while compared to the N80+PK treatment, the N160+PK treatment increased the yield by 1.49 t ha-1. In addition to agrotechnical factors, in maize production, the impact of the crop year is specifically of high importance. The average yield of hybrids (in the average of the different fertilizer treatments) was 6.81 t ha-1 in 2015, 11.86 t ha-1 in 2016 and 9.11 t ha-1 in 2017. When comparing the yield results against the precipitation data, it is clearly visible that the amount of rain fell in the January– October period is directly proportional to the average yield of maize. The effect of the crop year can be defined in a 5.05 t ha-1 difference in the yield.

The Impact

While several researchers have suggested that evolution should be explored from the initial years of schooling, little information is available on effective resources to enhance elementary school students’ level of understanding of evolution by natural selection (LUENS). For the present study, we designed, implemented and evaluated an educational activity planned for fourth graders to explore concepts and conceptual fields that were historically important for the discovery of natural selection. Observation field notes and students’ productions were used to analyse how the students explored the proposed activity. Additionally, an evaluation framework consisting of a test, the evaluation criteria and the scoring process was applied in two fourth-grade classes to estimate elementary school students’ LUENS before and after engaging in the activity. Our results suggest that our activity allowed students to effectively link all of the key concepts in the classroom and produced a significant increase in their LUENS. These results indicate that our activity had a positive impact on students’ understanding of natural selection. They also reveal that additional activities and minor fine-tuning of the present activity are required to further support students’ learning about the concept of differential reproduction. We also observed a low level of teleological predictions for both pre- and post-tests.

The Impact

Various levels of weed competition were implemented in a second-year well-established strawberry (Fragaria ×ananassa `Jewel') planting by cultivating and hand weed removal for defined periods of time over 3 years. The impact of weeds on subsequent productivity was then determined. Sixteen treatments were established where weeds were allowed to grow for defined periods (0, 1, 2, 3, 4, or 5 months) throughout the growing season. Treatments were maintained in the plots for 3 consecutive years. Spring weed biomass in 1997 had no impact on yield that same year. Weed biomass in 1997 was negatively associated with yield in 1998, although the trend was nonsignificant. However, several individual contrasts were significant. For example, the weed-free control treatment had the highest average yield, while season-long weed competition reduced yield by 14%. The inverse relationship between weed biomass and fruit yield became significant in 1999. For every 100 g·m-2 increase in weed biomass in 1998, fruit yield was reduced by 6% in 1999. Season-long uncontrolled weed growth reduced productivity by 51%. However, several plots with a limited amount of weed competition had higher yields than the continuously weeded control. These data indicate that yields from a well-established strawberry planting may not be vulnerable to a limited amount of weed competition for at least 2 years. Furthermore, data suggest that hand weeding and cultivation on a monthly basis for multiple years may be damaging as well. Growers should direct a majority of their efforts and resources toward controlling weeds in the planting year. Once the planting is well-established, growers may limit the number of times they hand weed to two or three per season.

The Cluster Front Line Demonstration (CFLD) programmes on oilseeds were carried out with respect to yield, extension gap, technological gap and economic returns in oilseed crops in Darrang district of Assam, India during 2016-17 and 2017-18 under NMOOP, Ministry of Agriculture and Farmers welfare, GoI. The fields were selected from different villages/clusters of the district. The observations on selected parameters of demonstration plots as well as control plots were recorded through experimental designs (‘Control-Treatment’) of social research. The results reflected that the average grain yield in demonstration plots of the selected oilseed crops namely; Rapeseed & Mustard, Sesamum and Groundnut was more compared to farmers practice. The crop sesamum recorded with the lowest extension gap (1.9q/ha), technology gap (0.90 q/ha) and technology index (11.25%) followed by rapeseed & mustard with 2.95q/ha, 0.31 q/ha and 3.42% and groundnut with 5.7q/ha, 15.6q/ha and 42.3% respectively. The highest additional income (Rs. 31307/ha) in demonstration plot over control was recorded in cultivation of groundnut followed by sesamum (Rs. 13134/ha) and rapeseed  & mustard (Rs. 11019/ha). The results revealed that the use of improved varieties, scientific cultivation practices in cluster mode facilitates to boost the productivity and profitability scenario of  oilseed crops in the district by minimizing the yield and technology gaps.

The effort to maintain the balance of the natural environment is the responsibility of all humans on earth. The Waso Community (Anak Waso Community, AWAS.com) and the Waso indigenous community have been trying to carry out their responsibilities by carrying out reforestation activities for three years. To see the extent of these efforts carried out and get its impact, it is necessary to do social research. The main objective of this social research is to observe and evaluate comprehensively the steps of the Waso children's community in carrying out reforestation activities for three years in the Bangka Poa region, as well as the impact of the activities carried out. To describe the efforts of the Awas.Com community in protecting the environment, researchers conducted social research carried out using the Planning, Organizing, Acting, Impact (POAI) method. The research results illustrate that this reforestation activity has shown a positive impact in the form of the recovery of the natural conditions of the Bangka Poa region and the stable water debit in several springs. The research study also looks at and evaluates that reforestation activities for three years in a row have had a direct or indirect impact on the growth and development of ecological, sociological, economic and religious awareness and responsibilities in the community and Waso young generation.

Abstract. Background: Worldwide prevalence of peripheral artery disease (PAD) is increasing and peripheral vascular intervention (PVI) has become the primary invasive treatment. There is evidence that multidisciplinary team decision-making (MTD) has an impact on in-hospital outcomes. This study aims to depict practice patterns and time changes regarding MTD of different medical specialties. Methods: This is a retrospective cross-sectional study design. 20,748 invasive, percutaneous PVI of PAD conducted in the metropolitan area of Hamburg (Germany) were consecutively collected between January 2004 and December 2014. Results: MTD prior to PVI was associated with lower odds of early unsuccessful termination of the procedures (Odds Ratio 0.662, p < 0.001). The proportion of MTD decreased over the study period (30.9 % until 2009 vs. 16.6 % from 2010, p < 0.001) while rates of critical limb-threatening ischemia (34.5 % vs. 42.1 %), patients´ age (70 vs. 72 years), PVI below-the-knee (BTK) (13.2 % vs. 22.4 %), and rates of severe TASC C/D lesions BTK (43.2 % vs. 54.2 %) increased (all p < 0.001). Utilization of MTD was different between medical specialties with lowest frequency in procedures performed by internists when compared to other medical specialties (7.1 % vs. 25.7 %, p < 0.001). Conclusions: MTD prior to PVI is associated with technical success of the procedure. Nonetheless, rates of MTD prior to PVI are decreasing during the study period. Future studies should address the impact of multidisciplinary vascular teams on long-term outcomes.

The Impact

Based on cross-country panel regressions, the paper analyzes the impact of external currency exposures on monetary policy, exchange rate regime and capital controls. It is determined that positive net external position (which, e.g., is the case for Russia) is associated with a higher degree of monetary policy autonomy, i.e. the national key interest rate is less responsive to Fed/ECB policy and exchange rate fluctuations. Therefore, the risks of cross-country synchronization of financial cycles are reduced, while central banks are able to place a larger emphasis on their price stability mandates. Significant positive impact of net external currency exposure on exchange rate flexibility and financial account liberalization is only found in the context of static models. This is probably due to the two-way links between incentives for external assets/liabilities accumulation and these macroeconomic policy tools.

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.
