Analysing Determinants of Household Broiler Chicken Meat Purchases amidst Social-Media Misinformation: A Tobit Study
Get PDFThe Indian poultry sector significantly boosts GDP. It is grown at 8-10% annually, reaching 41.94 billion (10.18% CAGR) from 2023 to 2028. Social media misinformation adversely affected the broiler sector, lowering prices and consumption. Using the Tobit Model, this study analysed Indian households' broiler chicken purchases during misinformation. Data on demographics, socioeconomics, and monthly consumption of chicken meat was collected from 503 respondents and analysed. On average, men favoured broiler chicken, while women preferred native chicken. The potential impact of social media misinformation on women's choices and the influence on households with senior citizens, which consumed significantly less quantity compared to their counterparts, remained intriguing. Unexpectedly, households with better incomes and more education purchased less broiler meat. Marital status, place of residence, cohabitation, and presence of children did not significantly affect the outcome. Muslim families purchased more broiler chicken meat, and larger households consumed more. Consumption frequency was important, with daily and alternate-day customers making larger purchases. Purchases of broiler meat were negatively impacted by the consumption of country chicken. Amidst social media misinformation, while a slight adverse impact on household broiler consumption may have occurred, it's notable that a significant portion of households (97.20%) continued to purchase broiler chicken meat, exhibiting the potential effectiveness of media-driven interventions in mitigating the impact of misinformation and reiterated the persistent favourability for broiler chicken as a dietary protein choice within the larger consumer demographic. The Indian poultry industry is vital for food security and economic growth, making it imperative to address social media-induced panic. Transparency, trust, and accurate information transmission are essential. In order to effectively handle market challenges, stakeholders need to take into account factors like demography and dietary preferences that impact consumer behaviour.Indian poultry sector is a significant contributor to GDP.

Dry matter distribution of banderita grass [Bouteloua curtipendula (Michx.) Torr.] at different plant strata
Get PDFObjective: To evaluate the dry matter distribution of banderita grass [Bouteloua curtipendula (Michx.) Torr.] in different plant strata.
Design/Methodology/Approach: A randomized block experimental design with five repetitions was used for the experiment. Each repetition consisted of three plants which were evaluated at different days after sowing (DAS), in three different plant strata: basal stratum (BS), middle stratum (MS), and upper or apical stratum (AS). The following variables were evaluated: dry matter yield (DMY), morphological composition (MC), leaf area (LA), plant height (PH), leaf:stem ratio (L:SR), and aerial part:root ratio (Ap:rR). An analysis of variance was performed, using the PROC GLM procedure of the SAS software; in addition, a comparison of means was carried out using Tukey’s test (α<0.05).
Results: SB made a greater contribution to DMY at 50 DAS, with a 16 g DMY plant-1 average, followed by MS, with 9 g DM plant-1, and AS with 3 g plant-1. The MC (g) in the BS registered that the stem made a greater contribution than the rest of the components (average: 12.3 g plant-1), while leaves from the MS and AS made the greatest contribution (2.6 g plant-1) up to 64 DAS. However, they were surpassed by the stem in the MS and by the inflorescence in the AS. In addition, BS registered the highest LA (173.4 cm2). The largest PH was recorded at 120 DAS (96 cm). The highest L:SR ratio reached 1.10 at 50 DAS, while Ap:rR recorded 3.82 at 92 DAS.
Study Limitations/Implications: The experiment was carried out under greenhouse conditions. Therefore, any extrapolation or comparison with field conditions should be done with caution.
Findings/Conclusions: The basal and middle part of a banderita grass (Bouteloua curtipendula) plant contains the highest forage accumulation (mainly in the leaves and the stem), while the highest biomass content in the apical part is produced by the inflorescence

Germination test of maize (Zea mays L.) seeds in a NaCl solution
Get PDFABSTRACT
Objective. To evaluate germination behavior and define initial vigor in maize seeds.
Methodology. The genetic material used were four batches of 20 hybrid seeds (M-2014, SR-2014, SR-2012 and SR-2011) of each one, which were germinated in a NaCl solution (0, 5, 10, and 15 dS m-1) in a germination chamber. A Randomized Complete Block experimental design was used, where the experimental unit was the seed lot and salinity level; with four replicates each. Once seeds with defined radicle and plumule were observed, they were counted for evaluation.
Results. When comparing the three lots from the same environment (production site) and different year, the statistical analysis indicated that longer seeds had lower germination percentages. Similarly, when comparing the lots from different production environments and the same year, M-2014 obtained the highest average germination percentage (92.19%). When evaluating the maximum salinity level, 15 dS m-1, a loss in the average germination percentage of 41.25% was observed.
Conclusions. The test was acceptable to evaluate the viability and vigor of a seed lot, because it was efficient in discriminating seed lots in relation to speed and uniformity in germination based on the NaCl solution.
Key words: Hybrid, saline solution, initial seed vigor, physiological quality.R

Assessment and selection of flowering inducers to increase productivity of mango cv. Ataulfo (Mangifera indica L.)
No full textObjective: To assess new flowering inducers used to increase the fruit yield in mango cv. Ataulfo trees, to substitute paclobutrazol.
Design/methodology/approach: Ten-year-old mango cv. Ataulfo trees were used, homogeneous in terms of health. The treatments evaluated were prohexadione calcium, cytokinins, itaconic acid, phosphonitrate, potassium nitrate and paclobutrazol. The experimental design was completely random blocks with five repetitions; each experimental unit and repetition consisted of one tree. The number of inflorescences, percentage of flowering, number of fruits, fruit yield by hectare, and profitability of treatments were assessed. The data were analyzed through ANOVA and Tukey’s means comparison (p<0.05).
Results: There were no significant effects of the treatments for number of inflorescences, percentage of flowering, and number of fruits; however, the homogeneous formation of inflorescences was found with itaconic acid. Prohexadione calcium (P-Ca) presented the highest fruit yield (19.32 t ha-1), but it does not differ from paclobutrazol (10.34 t ha-1). The highest profitability of the crop was obtained with prohexadione calcium, in which for each peso invested the amount of $1.51 was recovered.
Findings/conclusions: Prohexadione calcium can be an alternative for the use of paclobutrazol to induce flowering and increase the fruit yield of mango cv. Ataulfo in the Coast of Guerrero
