    Cytomorphometric analysis of oral squames Tobacco Smokers using oral brush biopsy: An exfoliative cytological study
    (Educational Society for Excellence, 2016) Shetty, R; Mukherjee, S; Dutta, N; Bhagat, DK; Sushma, KN; Pandey, V.
    Background: Tobacco is mostly regarded as one of the primary etiologic factor in causing oral cancer. Literature quotes studies have depicted the alteration of nuclear (NA) and cytoplasmic area (CA) induced by tobacco smoking and chewing. Also some authors have stressed on quantifying the role of cytomorphometric analysis in analysing these cellular alterations. Therefore, we evaluated the cytological and cytomorphometric changes in the oral squames using brush biopsy from buccal mucosa of tobacco users. Materials and methods: 200 patients of age group of 40-65 years attending the hospital OPD with history of smoking were included in the study. The patients were broadly divided into two groups; Shetty R, Mukherjee S, Dutta N, Bhagat DK, Sushma K N, Pandey V. Cytomorphometric analysis of oral squames Tobacco Smoker’s using oral brush biopsy: An exfoliative cytological study. IAIM, 2016; 3(5): 14-19. Page 15 smokers (n=150) and Non-smokers (n=50). The cytological samples were taken from clinically normal appearing oral mucosa, stained and analysed using Image analysing software. IndependentSamples T Test and One-Way ANOVA were used to assess the level of significance. Results: significant increase in Mean NA was observed in smokers as compared to non-smokers. Also, Mean CA decreased in smoker’s group as compared to non-smokers. Likewise, N/C ratio was found to be significantly elevated in smokers group. Cytomorphometric parameter changes showed significant alteration with increasing duration of smoking. Conclusion: Cytomorhometric analysis can be used to analyse the alterations occurring in cellular and nuclear level.

    Enriched Linz-Donawitz (LD) slag application for improving grain yield and quality of wheat grown under nutritionally poor degraded soil
    (Triveni Enterprises, 2024-12) Khokhar, S.K.; Goyal, V.; Kumar, N.; Usha, K.; Pandey, V.; Sharma, J.; Gupta, C.K.; Singh, B.
    Aim: To evaluate the impact of enriched steel slag on the physico-chemical characteristics of soil and yield attributes of wheat under poor quality degraded soil. Methodology: Steel slag was biologically and organically amended with natural sources of phosphorus (P), sulfur (S), potassium (K) and nitrogen (N) and characterized for its nutrient content along with biological activity. The impact of resultant products was assessed on soil quality and yield component traits of wheat for two consecutive years(2021-2022 and 2022-23). Results: Application of slag based products significantly (p<0.05) improved the plant height, biological yield, grain yield and ear bearing tillers (EBT) of -1 wheat even with 80% of recommended fertilizer dose (NPK). Further, in comparison to control, a moderation of soil pH (8.6 to 8.8), EC (0.18 to 0.20 dS m ), -1 -1 -1 OC (0.22 to 0.24 %) and essential mineral macronutrients viz., N (126 to 130 kg N ha ), P (8.0 to 13.0 kg ha ), K (100 to 125 kg ha ) were observed with the application of amended steel slag products. No significant change with respect to existing heavy metal concentration viz., Co, Ni, Cd and Pb in soil was observed when supplemented with amended slag products. Interpretation: Steel slag can be transformed favorably for on-farm application to improve wheat yield besides serving as an environmentally sustainable alternate of soil conditioner for the management of degraded soil.

    Simulation of Intra-seasonal Climatic Variability, Potential Yield and Yield Gap of Sugarcane for the South Gujarat Region, India
    (Ms. M. B. Mondal, 2024-11) Parmar, PK; Mali, SC; Tank, V; Pandey, V.
    The validated CANEGRO (DSSAT v4.7) model was used to simulate the intra-seasonal climatic variation viz. temperature (-3oC to +3oC) and rainfall (-25% to +25%) variability in sugarcane yield and quantifying the yield gap of sugarcane at Navsari, Bharuch, Surat and Valsad districts of south Gujarat region under the various management options included dates of planting, irrigations and fertilizers application and compared with the reported yield of the districts. The cane yield increased with an increase in rainfall and a decrease in temperature. In contrast, the cane yield decreased with a decrease in rainfall and an increase in temperature. The extent of effect was found to vary with crop growth stages. The potential yield of sugarcane simulated by the model in different districts was found to vary between 107.0 to 114.7 t ha-1, while the reported yield in these districts varied between 68.1 to 72.0 t ha-1. This resulted in a total yield gap between 38.9 to 45.5 t ha-1 in different districts. The highest yield gap was in Navsari district while the lowest yield gap was found in Bharuch district.
