Combining ability and component analysis in Bread Wheat (Triticum aestivum L.)

Paper ID- AMA-07-08-2021-10563

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

Paper ID- AMA-07-08-2021-10562

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

Paper ID- AMA-07-08-2021-10561

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.

Linking Actors Related-Stakeholders By Applying Network Analyses In Promoting Economic Advantages of The Goat Business In West Papua

Paper ID- AMA-07-08-2021-10560

The goat has been taking the places on farmers' needs just recently due to its products, i.e. slurry. It has brought a significant impact on economic advantages for small farmers. Those are due to stakeholders’ involvement in promoting its development. The study was done in Manokwari using the descriptive method by using focus group discussion towards twenty various represented individuals, groups, and mass institutions. The queries discussed concerning the background, resources delivery, inter connectivity among actors using Pearson correlation coefficient and similarity matrix, power, and interest of actor’s delivery of intervention and innovation of actors. The goat farming system in West New Guinea is shaped by related groups, lawyers, privates, and stakeholders rather than shareholders. The actors are important and have a positive effect. The actors have a low direct threat and slight high turn back effect. The four top shared resources consist of access, satisfaction, time, and space. The actors have a willingness to contribute in a long-term period and can sustain their support. However, the power of resources shared is neutral and therefore needs further intervention. The relationship of SNA is showing a relationship of similarity and with a greater positive correlation of each actor due to high interest and high power. The five top intervention for goat farming system is skills, feed materials, policy, funds, and satisfaction. While innovation needed by actors are skills, policy, knowledge, feed materials, and fund.

Effect of LCC based nitrogen application on nutrient uptake and use efficiency in wheat under irrigated sub tropics of Jammu

Paper ID- AMA-07-08-2021-10559

A two-year field experiment was conducted to investigate the effect of leaf colour chart (LCC) and chlorophyll meter (SPAD meter) based nitrogen fertilization on nutrient uptake, use efficiency and productivity of wheat crop under irrigated sub tropics of Jammu. The investigation conducted at Divisional Research Farm of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main campus Chatha during Rabi 2018-19 and Rabi 2019-20. Experiment was laid out in randomized block design with four replications and six treatments viz. control, nitrogen application based on LCC ≤ 3, nitrogen application based on LCC ≤ 4, nitrogen application based on LCC ≤ 5, sufficiency index based nitrogen application and recommended dose of fertilizer (100:50:25:37.5 kg/ha N:P2O5:K2O:S) along with well fertilized reference plot with 150 per cent recommended dose of nitrogen (150:50:25:37.5 kg/ha N:P2O5:K2O:S) for calculating sufficiency index. Among different treatments of nitrogen management, significantly highest yield and nutrient uptake were recorded with LCC ≤ 5 based nitrogen application. However, sufficiency index based nitrogen application recorded numerically higher nitrogen use efficiency and apparent recovery of nitrogen whereas recommended dose of nitrogen application recorded maximum physiological efficiency.
