Growth and Instability analysis in Wheat in India
The present investigation deals with the use of Coefficient of Variation (CV), Cuddy-Della Valle index (CDVI), Coppock’s instability index (CII), to determine the instability in the wheat production in major producing states in India. Time series data for the period (1960–1961 to 2018–2019) on area, production, yield and MSP of wheat have been used in this study. Time series data was divided into six decades of 10-year interval to measure the instability in area, production and yield of selected crops into different periods. Annual growth rate of area, production and productivity of wheat crop in India and major wheat growing states were also observed by fitting to the time-series data in linear function.
Date Fruit Varieties Classification Based on Dryness Levels by Using YOLOv3
Fruits native to the Middle East, such as dates, are small fruits that can be diverse and popular in the Middle East. There are several common date varieties, each with different characteristics. Date classification is a critical tool in date processing which may be an expensive operation. In this research, we present a computer vision and color perception strategy for the automatic classification of date fruits. The approach was introduced and tested empirically based on image data representing of three distinct date classes at various dryness stages. You only look once (YOLO) is a state-of- the-art, real-time entity detection device that has been used for this reason. The best precision varied from the 0.29 range to the 1.00 range.
Combining ability and component analysis in Bread Wheat (Triticum aestivum L.)
In the present study a diallel set of 9 x 9 was attempted by crossing nine bread wheat genotypes in all possible combinations excluding reciprocals. The mean squares of nine diverse parents and 36F1s due to GCA and SCA component were significant for all the thirteen traits. These outcomes show the importance of additive variance in the inheritance of all the traits. The comparative importance of additive and non-additive components was revealed by checking the components of variance (s²g and s²s), heritability in broad-sense (Hb), narrow-sense (Hn) and gca/sca ratio. The magnitude of GCA component (s²g) and gca/sca ratio was higher for plant height and peduncle length, indicating that these two traits were under the control of additive genetic variance and all the others traits were controlled by non-additive genetic component. Based on general combining ability effects and per se performance, parents WH1184, HD3086 and HD3059 were found the good general combiners for grain yield per plant. On the basis of per se performance and SCA effects the crosses viz., HD2967 × WH1184 and HD3059 × Raj3765 were found as good specific cross combination. These crosses can be extensively used in further breeding programmes to develop superior pure lines.
Financial analysis of dairy companies in India A comparative study of selected companies
The study has made an attempt to analyses the solvency and profitability position of select Dairy companies in India. The select companies are CDPL, Hatsun, Heritage, Parag and Prabhat. The solvency has been explained by debt-to-equity ratio, interest coverage ratio, and proprietary ratio; profitability has been explained by ratios such as return on total assets, return on equity. It can be concluded that there is a significant difference in terms of current ratio, debt to equity ratio, proprietary ratio, debtors turnover ratio, creditors turnover ratio and total assets turnover ratio of select dairy firms in India. It means that at least one of the means of the sample is different. The test results also indicated that there is no significant difference in terms of inventory turnover ratio, fixed assets turnover ratio and interest coverage ratio.
Indigenous Bacteria for Increasing the Shelf Life of Seaweed (Caulerpa lentillifera) in Laboratory Scale
The optimum of culture time and concentration of alginate for antimicrobial activity of both potential strain L18 and L8 were carried out for 12h, 24h, 36h, 48h, 60h, 72h, 84h, 96h, 108h and 120h by agar well diffusion method. The cultured broth of two best parameters in the previous experiment was designed as bio-products for application on preservation of sea grapes after harvesting. The effectiveness of those bio- products was expressed in the number of pathogenic bacteria counted. The physiological state of sea grapes was reliably evaluated with a diving pulse-amplitude-modulation fluorometer quantifying the chlorophyll fluorescence parameter of maximum quantum yield of photosystem II (PSII, Fv/Fm). Results showed strain L8 was strongly inhibited against Pseudomonas sp. A1 and Klebsiella variicola S1 after 36h cultivation whereas the strain L18 was most inhibition Pseudomonas sp. A1, Enterobacter sp. T1, Citrobacter freundii A2 after 60h cultivation. The concentration of alginate which was the most effective for antimicrobial activity of L8 was 0.3% and L18 was 0.2%. The bio-products added treatments showed a lower number of pathogenic bacteria from 1000 to 10000 times than those in the control samples. Bio-products treatments had not shown significant differences in total phenolic content and chlorophyll-a. In addition, the data from PSII measurement showed that two treatments L8 plus 0.3% alginate and L18 plus 0.2% alginate yielded much better productivity of PSII than other two control samples. The shelf life of edible seaweed could be increased up to 10 days at room temperature, when it was sprayed with bio-products.
