Lifetimes of products are inspected in life tests upto a predetermined time t0, which may observe early failure of some of the products; incorporation of this fact may not only reduce the cost of inspection, but also provide some more insight into the failure mechanism. In this paper, we consider a two-stage time censoring scheme by dividing test truncation time t0 into two parts [.. formula..] and observe the number of failures in each interval, considering the remainder items as censored at t0. The trinomial distribution has been used to develop life test acceptance sampling plans for establishing quantile life of items having Weibull lifetimes. The proposed life test sampling plan gives added advantage to producers and extra safeguard to consumers, as compared to the life test sampling plans available in the literature for the Weibull distribution. Tables of plan parameters are constructed through code written in R 4.1.2, and illustrated for some real-life industrial cases..

Furthermore, blockchain platform benefits producers by enhancing their reputation, increasing their competitiveness and reducing fraud by eliminating undesirable practices in the supply chain. This research paper aims to analyze the determinants of blockchain technology adoption in agricultural supply chain. Grey relational analysis is employed to identify the determinant factors of blockchain technology adoption in the supply chain. The factors for blockchain technology adoption in supply chain are identified based on the literature review collected and focus group discussion with experts. Experts are insisted to rate the factors based on the five point likert scale. The findings revealed that data transparency, traceability, interoperability, data immutability and high value pricing, product type, organization trust, and government support can influence the blockchain adoption in supply chain. The findings conclude that priorities must be given to those influential factors which will help the organizational stakeholders in formulating suitable strategy for effectively implementing blockchain technology in the agricultural supply chain..

Traditional imputation methods often introduce biases, prompting the need for a robust solution. The EM algorithm, anchored in a mixed effects model, iteratively estimates missing values, demonstrating its efficacy in a practical RCBD scenario. Through 15 iterations, the algorithm converges to stable parameter estimates. Root Mean Square Error (RMSE) and bias calculations validate the accuracy of imputations. This study establishes the EM algorithm as a powerful tool for enhancing the integrity of analyses in RCBD experiments with missing data..

In this article, we are trying to extend this method when the population size is countably infinite. In finite population, a unit has equal probability of being chosen in most of the cases except PPS. However, this cannot be so in infinite population. In that case,we approximate infinite population by large finite population and then use the traditional finite population method. It is true that the original population have some distribution, but without knowing that we are using systematic sampling method and based on that we are estimating population mean. We want to see the effectiveness of this systematic manner if the population has some specified distribution. Here, based on Poisson assumption, we provide some approximation methods and see performances in each case. However, this is to be done for some important distributions also. Here, the problem has been viewed in three ways and out of that the first method performs well, where the Poisson probabilities has been assigned to all possible samples rather than any truncation of the infinite population by finite population. .

Most of the informal workers comprise the agriculture sector. So, the present paper is focused on the growth of the unorganized sector in India with special emphasis on the agriculture sector. The agriculture share in gross value added is higher than other sectors. The proportion of selfemployed is higher than casual labour and regular waged workers. In rural areas, workers? livelihoods are dependent upon agriculture because when people have limited or no livelihood opportunities and for earning no formal jobs are there then to fulfil the basic requirement of the family, they are involved in jobs in the informal sector. The government has initiated many measures to formalize unorganized sectors like MGNREGA, Udyam, e-Sharam portal, Atamnirbhar package etc. It is suggested that government should organize awareness camps to inform people about formalization and its potential impact on their lifestyles.

Different non-linear and ARIMA models were used to forecast and analyse area, production, and yield trends. The cubic model for production and yield of the mango crop farmed in Andhra Pradesh and the Power model for area trends both fit the data well. For forecasting mango area, production and yield, the best models were ARIMA (2,0,2), Cubic and ARIMA (2,2,1) based on model selection parameters such as adjusted R2 , RMSE, and MAE. The findings showed that the yield, production and area of the growing mango crop in Andhra Pradesh would likely exhibit an upward trend in the future years. The projected figures for 2022-2023 were roughly 641 thousand hectares of mango area, 6565 thousand metric tonnes of production and 45.4 mt/ha of mango crop yield.
