Determination of Agronomic attributes and Essential Oil yield of Peppermint (Mentha piperita L.) varieties under altered planting time and harvesting schedules
A field experiment was carried out to evaluate the ideal planting dates and harvesting stage of peppermint varieties to produce higher herb and essential oil yield of peppermint during two consecutive spring seasons of 2019 and 2020 at two locations viz. Ludhiana and Bathinda. The experiment in split plot design contained the combinations of two varieties (Local and ‘Kukrail’) and three dates of planting (January 15, January 30 and February 15) in the main plots and three harvesting schedules [120, 130 and 140 days after planting(DAP)] in sub plots. The late planting of peppermint varieties on Feb 15 significantly enhanced growth and development of crop in relation to significantly higher dry matter accumulation and leaf area index; the key contributing attributes to herb and oil yield of crop irrespective of the agro-climatic conditions of two different locations. However, Feb 15 planted crop produced significantly higher herb yield than Jan 15 planting while statistically at par with Jan 30 planting. In addition to it, harvesting the peppermint varieties at 140 DAP indicated significantly higher herb yield by 16.3 and 31.2% than 130 and 120 DAP respectively under Ludhiana conditions and similarly, by 11.3 and 20.2% respectively at other prescribed location.
Shelf life evaluation of processed Assam lemon (Citrus limon Burm) juice
Present investigation was carried out to evaluate the shelf life based on the microbial and sensory analysis of processed Assam lemon juice subjected to treatments like pasteurization and addition of KMS. The processed juices were stored in refrigerated conditions and subjected to microbial evaluation every 15 days. The result showed that the untreated juices were spoiled just after 90 days whereas the samples given a combination of pasteurization and KMS treatment remained within microbial permissible limit for 180 days in ripe Assam lemon juice giving the best results. However, the matured juice was discarded after 165 days due to exceeding of microbial permissible limit. Sensory results suggested superior quality and stability of pasteurized and KMS treated juices in terms of colour, taste and overall acceptability suggesting that mature and ripe Assam lemon juice samples treated with a combination treatment of heat and chemical preservatives can be stored for a period of 180 days in refrigerated conditions.
Field studies of crop geometry and nitrogen application on growth and yield of peppermint (Mentha Piperita L.)
Peppermint (Mentha piperita L.) is mainly cultivated during the spring season for its medicinal and quality uses. The present investigation was planned to evaluate the row spacing and nitrogen application rate to ensure potential herbage yield and superior quality essential oil. The experiment was laid out in split plot design at two locations (Ludhiana and Bathinda) keeping combinations of Two varieties (Local and Kukrail) and three row spacing (30 cm, 45 cm and 60 cm) in main plots and four nitrogen levels (0, 50, 75 and 100 kg/ha N) in sub plots. The Kukrail variety performed significantly better than Local variety in terms of plant height, stool count, leaf area index resulting in 7.47 % and 7.69 % higher herbage yield at Ludhiana and Bathinda, respectively. Planting of peppermint at 45 cm row spacing produced significantly higher growth parameters like plant height, dry matter and fresh herb yield than 30 cm while the differences between 45 and 60 cm were non-significant. Also, the application of 75 kg/ha N produced significantly higher herb and oil yield than 0 kg/ha N and 50 kg/ha N while the response beyond 75 kg/ha N was non-significant at both the locations.
Molecular validation of markers linked to rust resistance (leaf and yellow) and grain quality genes in a UP 2338-derived BIL population of bread wheat (Triticum aestivum L. em Thell.)
The widespread use of DNA markers has created new opportunities for plant breeding to protect plants from biotic and abiotic stress. The development of rust-resistant wheat varieties is aided by the use of DNA markers, which are helpful in the fight against rust infections in wheat and are essential for the identification, characterization, and expression of rust resistance genes. It is imperative to combine rust resistance with grain quality features. Genes related to grain quality and rust resistance, such as GPC-B1, HMW-GS, Lr34, Lr19, Lr24, and Yr15, are crucial for preventing rust disease-related declines in grain quality and maintaining wheat productivity. Significant correlations were detected between the goal attributes and the molecular validation of markers associated with rust resistance (leaf and yellow) and grain quality genes in a BILs population of bread wheat. The expression of genes such as GPC-B1, HMW-GS, Lr34, Lr19, Lr24, and Yr15 was validated via the use of molecular markers in the validation of rust resistance and grain quality genes within wheat cultivars. In addition to being present alone and in combination with other rust and quality genes, the GPC-B1 gene was found in 82 BIL populations. However, the HMW-GS gene coexisted with additional genes in 169 BILs population. The Lr34 gene was found in 69 populations and was found in different combinations with Lr34/Yr18. Resistance genes to Lr19, Lr24, and Yr15 were also identified; these combinations included two, three, four, and five genes, respectively. Among the 217 chosen BILs, 23 also exhibited all of the genes GPC-B1, HMW-GS, Lr19, Lr24, Lr34, and Yr15. The confirmed common lines will be used for further development of wheat breeding.
The Impact of Financial Development and Economic Growth on the Economy of Kingdom Saudi Arabia.
The purpose of this study is to use the fully modified ordinary least squares (FMOLS) method to examine the connection between financial development and economic growth in Saudi Arabia from 2013 to 2023. The growth of the credit market (bank loans to the private sector) and the stock market (the general stock market index) have been the manifestations of the evolution of financial markets. According to the findings, domestic bank credit to the private sector influences economic growth in the long run, but in the short run, it has little effect and even has a negative impact. In contrast, the stock market index has an unexpectedly small but positive impact in the short term, but a long-term beneficial effect that is barely noticeable. Lastly, there is good and substantial evidence that increasing industrial production will contribute to economic growth, both now and in the future.
