The advancement of new technologies has highlighted the need for a more precise assessment of the life of goods and systems before allowing them to serve in the market. Due to time and cost constraints, tests must be able to generate rapid and reliable life information, which is not attainable using conventional life testing methods. As a result, various censorship schemes, along with accelerated life testing, in which goods are subjected to increased stress in order to determine the life characteristics of products and systems in a short period of time, have been deemed significant tools. In addition to reducing product testing time through the use of accelerated life testing and various filtering techniques, understanding the impact of failure reasons is critical. In order to get precise failure information, the observer must distinguish between various failure causes. The current work aims to quantify the amount of information accessible for test item lifetimes by employing step-stress partly accelerated life tests with competing risks (CR) based on an adaptive type-I progressive hybrid censoring scheme (AdTI-PHCS). The Rayleigh distribution is used to explain the distribution of test item lifespans. To get point and interval estimates, the maximum-likelihood estimation (MxLE) approach is implemented. Moreover, to assess the performance of the given model parameters, a Monte Carlo simulation approach is utilized.
Melon is one of the most beloved healthy food crops worldwide that needs to increase its production and quality. This study was designed to estimate heterosis, combining abilities, gene action, and heritability in hybrids of melons to develop their yield and quality. The half-diallel cross method was used to produce six F1 hybrids driven from four inbred lines in a randomized complete block design (RCBD) with three replications. The hybrids and their parents were evaluated at the El-Gemmeiza Agriculture Research Station, Horticulture Research Institute, Agriculture Research Center, Egypt. The results revealed that the majority of the crosses had significant heterosis over the midparents, with better parent and chick hybrids for the majority of the traits. The highest significant heterosis over mid parents was 135:15%. The cross P1 x P3 was recorded for average fruit weight, followed by total yield / plot (108.97%). Analysis for combining ability indicated that GCA and SCA variances were highly significant. The ratios of GCA/SCA for all traits were lower than unity. The results reported that none of the parents showed either the best combiner or the best specific combiner for all traits. The broad-sense heritability magnitudes for number of leaves / plant and plant length traits ranged from 83.06 to 99.96%, while the narrow-sense heritability values ranged from 0.42 to 74.08% for total yield / plot and number of fruits / plot traits. These results indicate that selection may be more effective for improving traits in genotypes in early generations.
Texture is perilous to the appropriateness of fruits and vegetables, both fresh and cooked. Textural properties data of tomato are important in adoption and design of various handling, packaging and transportation systems. Textural properties namely, bio yield point, flesh firmness, fracture energy and total energy were determined with respect to maturity stage under immature, mature and over mature situations as well as storage temperatures under ambient condition (25o C) and low temperature condition (6o C). The bio yield point (kg), flesh firmness (kg), fracture energy (kg.s) and total energy (kg.s) decreased with different stage of maturity, storage period and temperature of tomato was significant at 5 per cent level.
A field experiment was conducted during 2016–17 and 2017–18 to assess the productivity, profitability and soil health of a rice-based crop sequence under different sowing dates and nitrogen management. The experiment was laid out in a factorial randomized block design with three replication. The treatment consisted of four dates of sowing for rice, green gram, maize, and four N management practices. Early sowing of rice, green gram and maize, combined with applications of 50% nitrogen as inorganic plus vermicompost @ 1.0 t/ha, resulted in a significantly higher grain yield. Performance on the crop sequence as a whole showed that early sowing of the crops produced the highest rice equivalent yield (REY), production efficiency (PE), land utilization efficiency (LUE), nutrient use efficiency (NUE), net return and B C ratio compared to later dates of sowing of the crop in the sequence. Application of 50% N as inorganic along with vermicompost @ 1.0 t/ha recorded significantly higher productivity, profitability and efficiency indices as compared to other treatments. There was maximum improvement in soil health indices with respect to organic carbon, microbial biomass carbon and soil microbial populations when inorganic nitrogen sources were combined with organic sources.
An experiment was initiated at a farmers field at Manikpur area, Bongaigaon, Assam, India during 2020-21 and 2021-22 to resolve the problem of drop of fruitlets leading to low fruit retention in Thailand ber. The statistical design of the experiment was factorial randomized block design, where two types of variety, two pruning height and eight micronutrient combinations alongwith control were tested. In the investigation, spraying with micronutrient combinations of borax 0.5% together with ZnSo4 0.5% was proved to be the best in controlling fruit drop and increasing fruit retention in Thailand ber.
