However, challenges such as high-water consumption, labour intensiveness, and environmental degradation have prompted the exploration of alternative methods. In this study, we assessed the impact of various crop establishment methods (CE) i.e. conventional puddled transplanting, direct drill seeding on flatbed (DSR), and direct seeding on raised beds (FIRB) on five stress-tolerant rice varieties (V) i.e. DRR 42, DRR 44, Sukha Dhan 5, Sukha Dhan 6 and Sarjoo 52 by analysing biochemical parameters i.e. total sugar content, starch content, MDA content, SOD content and yield outcomes. Our findings reveal significant variations in biochemical parameters and yield across different CE and V combinations. Notably, FIRB consistently outperformed other CEs, indicating its potential for enhancing stress tolerance and yield. Similarly, DRR 44 exhibited superior performance across most growth stages. Our study highlights the potential advantages of FIRB method in mitigating water wastage and addressing the limitations of conventional transplanting practices.","PeriodicalId":505977,"journal":{"name":"Journal of Scientific Research and Reports","volume":"30 2‐3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141002409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work identified and studied the active photosynthetic pigments in tomato crop (Solanum lycopersicum) at each growth stage and grown in an open field under Sahelian conditions. Phytochemical screening, UV-visible and Fourier transform infrared spectroscopy, and thin layer chromatography analyses were done on tomatoes leaves samples. The results, first, revealed the presence of phytoconstituents such as triterpenoids and carotenoids. Then, UV spectra combined with FTIR and thin layer chromatography showed that chlorophylls (a and b), xanthophyll (lutein) and carotene (mostly β) are being synthesized at different proportions during all growth stages. Besides, the photosynthetic pigments showed more activity during the flowering stage than at the other growth stages. The various action spectra showed intense absorption within the intervals 400 – 510 nm and 560 – 710 nm which seem to be vital radiation ranges for photosynthesis.  Knowing these optimum plant’s needs can help in a choice of better outdoor and indoor cultivation conditions that can ensure necessary radiations for optimum plant growth.","PeriodicalId":505977,"journal":{"name":"Journal of Scientific Research and Reports","volume":"71 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141013649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil, a clay loam with slightly alkaline pH, low nitrogen, medium phosphorus, and high potassium levels, received RDF 60:30:30 N: P2O5: K2O kg ha-1 at sowing. The investigation monitored various growth parameters, including plant height, number of tillers, number of functional leaves, and dry matter accumulation, at different growth stages. The study revealed that early sowing at 26 MW significantly influenced plant height, number of tillers, and dry matter production, favoring greater vegetative growth. The Renadu variety consistently exhibited superior performance in plant height, tiller count, and dry matter accumulation compared to other varieties. Days to 50% flowering and maturity were significantly affected by both sowing dates and varieties, with early-sown crops taking more days to reach these stages. Grain yield, straw yield, and harvest index were influenced by sowing dates and varieties, with the combination of the Renadu variety and 26 MW sowing exhibiting the highest grain yield and straw yield. Renadu also displayed a superior harvest index, emphasizing its suitability for optimal growth and yield. The study recommends sowing foxtail millet on 26 MW or 28 MW, particularly with the Renadu variety, for achieving maximum growth and yield during the Kharif season.

The pest was detected in red sanders plantations located in Dharmapuri and Tenkasi districts of Tamil Nadu, as well as in Surat, Navsari, and Tapi districts of Gujarat, India, during August 2023. In both regions, young red sanders trees aged between 2 to 16 years were affected, with incidence levels varying from 2.24% to 10.86% in the affected plantations. Signs of infestation include the presence of galleries, bore holes in cut stems, complete drying, and mortality of the trees. Initially, larvae feed on the bark, and as they mature, they tunnel through the cambium and wood, impeding nutrient flow and leading to tree mortality. The larvae's deep tunneling within the wood makes them difficult to eradicate with pesticides. Adult beetles typically emerge in peak numbers during April to May and November to December, coinciding with their mating period and selection of host plants for egg-laying. This report aims to outline the damage caused by the stem borer in red sanders and document ongoing monitoring efforts to support interim management strategies.","PeriodicalId":505977,"journal":{"name":"Journal of Scientific Research and Reports","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140361656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
