Export and Import performance of Walnut in India: An empirical analysis through Revealed Comparative and Trade advantage along with Revealed competitiveness
Walnut is the most important temperate nut of India with Jammu and Kashmir being the highest contributor (90%) to the total walnut production in the country. This study focuses on analysing the export performance of Indian walnut from 2005 to 2020. The secondary data for this research was collected from Agriculture and Processed Food Products Export Development Authority (APEDA) and United Nations Statistics. Revealed Comparative advantage (RCA), Revealed Import advantage (RMA), Revealed Competitiveness (RC) and Revealed Trade advantage (RTA) was used to assess the Export and Import stand of India globally. The import penetration ratio (IPR) was used to assess the protection levels of domestic markets. The findings of this research demonstrate that the RCA of walnut has been below 1 since 2011, depicting the country’s disadvantage in world export with an RCA of 0.136 in 2020, whereas the RMA has been increasing since 2014 which was 0.02 and then 0.81 in 2020. In addition to that, RTA has been continuously declining in 2011which was 0.65 and then being its lowest at -0.68 in 2020. Similarly, RC has also been declining since 2005 (11.85) and has remained below zero since 2016 with -1.79 in 2020. Thus, the IPR has been positive since 2015 which shows that Indian markets have been lowering their tariff and protections. Therefore, the novelty of this research is that Indian walnut export has been losing its advantage in global trades as our area and production of walnut didn’t show much growth over the last 15 years but our demand has been increasing continuously, so importing turned out to be highly advantageous as it fulfilled our domestic demands.
The Relationship of Food Intake to Nutritional Status in Children with Disabilities
Children who have disabilities or special needs are more likely to have physical impairments, which may include deficiencies in motor function, body form, or body size. Physical impairments are prevalent. Children who need particular care are included in the category of high-risk individuals. The health problems are also not considerably different from those that are experienced by children and adolescents in the general population. One of these concerns is a nutritional intake that is either insufficient or excessive. The objective of this study is to investigate the relationship between having a disability and the nutritional condition of children who have disabilities. The data for this research were collected via the use of a cross-sectional design and a thorough sampling method from forty children with disabilities who voluntarily gave their agreement to take part in the study. The retrieval of information via the use of a food intake questionnaire. It was shown that 52.50 percent of children with disabilities had a nutritional status of 21 or above, which is regarded to be normal. The majority of those that participated in this study were female. The consumption of carbs was the most abundant (441.7 g), while the intake of vitamins was the least abundant (0.27 g). The vast majority of children with disabilities exhibit normal levels of nutritional health. Protein and vitamin intake in the diet are directly connected to a person's nutritional health.
Efficacy of Synthetic and Biopesticides Against thrips, (Scirtothrips dorsalis Hood) in Chilli
Investigations on “Efficacy of synthetic and biopesticides against thrips, (Scirtothrips dorsalis Hood) in chilli” were carried out at Samajik Vigyan Kendra, Dr. B. R. Ambedkar University Rehti, (Village Bordi) Tehsil- Nasrullaganj, Distt- Sehore (M.P.) during Rabi, 2018-19 and 2019-20. A total of ten treatments including untreated control was taken to test their efficacy. Based on the mean per cent reduction in thrips population in all three sprays the treatment of fipronil (77.48%), was found to be the most effective, followed by spinosad (73.53%), emamectin benzoate (71.99%), thiamethoxam (70.23%) former three treatments were statistically at par with each other in their efficacy. The treatments of carbosulfan 25 EC (67.09%), propalgite 57 EC (66.57%), neem (65.10%) and fenpropathrin 30 EC (64.78%) percent reduction, formed a moderately effective group of insecticides. The minimum reduction was noticed in bifenthrin 10 EC (58.65%). The highest fruit yield of 106.26 q ha-1 was recorded in the plots treated with fipronil, followed by thiamethoxam (104.20 q ha-1), emamectin benzoate (100.35 q ha-1), spinosad (98.11 q ha-1). The lowest fruit yield was recorded in the plots treated with neem (56.95 q ha-1) followed by bifenthrin (60.50 q ha-1). The maximum cost-benefit ratio of 1:2.98 was recorded in the treatment of fipronil, followed by thiamethoxam (1:2.91), emamectin benzoate (1:2.79) and spinosad, (1:2.72). The cost-benefit ratio of 1:2.38, 1:1.87, 1:1.61, 1:1.49, and 1:1.43 were recorded in the treatments of fenpropathrin, carbosulfan, propelgit, bifenthrinand neem respectively. The descending order of insecticides effective in controlling this pest and their order of efficacy was fipronil> spinosad>emamectin benzoate> thiamethoxam>carbosulfan>propalgite> neem>fenpropathrin& bifenthrin.
Interactive effects of conservation tillage practices and precision nitrogen management options on the performance of Wheat (Triticum aestivum L.) in Indo-Gangetic Plains
This two year of study was conducted during 2017–18 and 2018-19 to assess the influence of Conservation tillage practices (CTPs) and precision nitrogen management practices (PNM) on wheat genotype DBW-17 in sandy loam soil of Modipuram, Meerut, Uttar Pradesh. The experiment comprising four crop establishment methods (CEMs) [(Zero tillage (ZT), reduced tillage (RT), furrow irrigation raised beds (FIRB), conventional tillage (CT)] in the main plot and five precision nitrogen management options [N 80:20, N 33:33:33, N 80 – LCC, N 50:50 and farmers fertilization practice in sub-plot and laid out in split-plot design with three replications. The results of the current experiment showed that the use of a furrow irrigated raised bed system (FIRB) and the application of nutrients like N 80-LCC for wheat seemed to be the best combination for achieving higher crop growth characteristics and yield under the north-western plain zone of Uttar Pradesh. So, during two years of study, it was confirmed that FIRB and N 80- LCC based practices on wheat fertilizer demand could significantly increase efficiency and achieve a higher yield level, which provides a theoretical basis for the realization of the synergistic combination.
Study on Tagetes minuta (Fam. Asteraceae) essential oil and its effects on some stored product insects
The study curried out to study the chemical composition of tagette essential oil and evaluate the insecticidal activities of tagette oil against two major stored product insects Tribolium castaneum and Rhyzopertha dominica. The study indicated that, Dihydrotagetone was the main component in tagette oil with 28.85 % percentage of total oil followed by Cis- Ocimene with 26.91%. For T. castaneum the highest concentration 0.24 mg/cm2 had the highest repellent effect with 87.5% repellency after over the 24 h duration. All tested concentrations had a repellent effect on R. dominica the repellency percentage was increased with increasing exposure period and concentrations. tagette essential oil showed fumigant toxicity against R. dominica and T.castaneum. However, R. domenica was considerably more susceptible than T. castaneum. For R. dominica after 3 h tagette essential oil had fumigant effect, with LC50 value 0.26 mg/cm3 while after 6 h tested oil had fumigant effect with LC50 value 0.17 mg/cm3. While after 48 h T. minuta oil had the fumigant effect with LC50 value 0.48 mg/cm3. tagette oil had contact effect at all exposure periods of exposure against T. castaneum with LC50 of (7942.9, 3375.0 and 2967.7 mg/kg) after 24, 48 and 72 h of exposure, respectively. Data also showed that tested essential oil had contact effect on adults of R. dominica with LC50 of (820.7 and 665.5 mg/kg) after 24 and 48 h of exposure, respectively.
